OUR PROJECT EXPERTISE




In the projects experience section of this qualification manual you will find
summaries of our current and historical projects, most from the last 15 years,
that demonstrate our breadth and depth of capabilities. The project section
is organized into the following topics:

COAL FUEL HANDLING
Coal handling is a critical step in the power generation process as there are
multiple points in the chain from production. R&S has developed innovative
solutions to meet requirements at each of these stages, including the design
and construction of rapid discharge unloading facilities, stacking tubes,
conveyor systems, reclaiming hoppers, crushers, silos, and various other
systems. In addition, R&S designs and installs industry-leading dust
suppression and collection systems that maintain air quality throughout
the coal handling process. The Company is capable of taking full turnkey
design and construction responsibilities for coal fuel facilities and has
completed both new and retrofit projects

FLUE GAS DESULFURIZATION (“FGD”)
FGD is the technology used for removing sulfur dioxide from the exhaust flue
gases in coal-fired power plants. Environmental protection legislation mandates
that utilities install FGD systems to curb their emissions profile and lessen their
impact on the environment. The most common FGD technology is wet scrubbing,
which uses a crushed limestone reagent to absorb SO2 from the power plant’s
flue gasses. A byproduct of this process is gypsum, a compound that is marketable
for use in the building products industry.
R&S is the industry leader in the design, procurement, and construction
of solutions for handling limestone and gypsum within the FGD process.
The Company’s engineers understand the challenges associated with moving
limestone and gypsum and have years of experience designing grinders, dryers,
impactors, conveyors, screen feeders, sizing screens, surge bins, silos, and
boiler houses. The Company is also experienced in the handling of lime and
activated carbon from dry scrubber and mercury removal applications.

    OUR PROJECT EXPERTISE




    ALTERNATIVE FUEL HANDLING
    As utilities and other power generators strive to reduce operating costs and
    explore environmentally friendly technologies, they are employing alternative fuel
    sources, such as petroleum coke, bituminous waste (gob), biomass, and bio-fuels.
    Wood chips, used tires, sugar cane waste, municipal waste, and virtually any other
    combustible material are being considered as alternative fuel sources.
    In particular, R&S engineers have extensive experience and knowledge of how
    petroleum coke is handled at the refinery, utilized as a fuel source, and its
    applications to the cement industry. This assures careful analysis, correct criteria
    and equipment selection, and efficient facility configuration for every project.

    COAL MINING AND PROCESSING
    Leveraging a history of engineering excellence and material handling expertise,
    R&S began designing solutions for coal mining and processing customers in the
    early 1900s and quickly established itself as a leading provider of coal handling
    solutions for mining applications. Today, R&S continues to offer the coal mining
    and processing industries innovative and cost effective solutions for cleaning,
    transporting, conveying, storing, reclaiming, and loading coal.

    PRECIOUS & BASE METALS
    R&S provides material handling and processing solutions to customers mining
    various precious and base metals, including copper, gold, silver, and others.
    The Company has experience designing and implementing systems that enable
    gold and silver extraction, carbon absorption technologies, and grinding, flotation,
    and leaching circuits for high-grade ore processing. R&S also maintains strong
    relationships with outside processing experts so that it has access to additional
    resources and capabilities that can be employed as necessary in conjunction
    with its materials handling capabilities.

CVY-13 to pick up any tramp iron that may have found its way into the
as-received coal. A two way diverter gate then directs the coal to an existing
conveyor or through another diverter gate and into one of two surge bins.
One surge bin is the existing Unit 3 bin and the other bin is a newly provided
bin for Unit 4. The new Unit 4 surge bin includes a slide gate at the bottom
that will allow the coal to be fed through a new coal crusher and onto new
reclaim conveyor that has a capacity of 1,000 TPH.
The reclaim conveyor also feeds the coal into Junction House No. 2 and onto
conveyor CVY-16. A new magnetic separator has been installed at the head end
of CVY-16 to pick up any tramp iron that may have come from the crushing
operation. Conveyor CVY-16 feeds the coal into Junction House No. 3 and onto
new power feed conveyor CVY-17, also with a capacity of 1,000 TPH. Conveyor
CVY-17 feeds the coal onto fixed tripper conveyor CVY-18 located in the tripper
bay of the new unit 4 generating building. Conveyor CVY-18 feeds the coal into
the five (5) coal silos with the same capacity of 1,000 TPH.
A dust collection system picks fugitive dust from all transfer points and
pneumatically conveys the dust to one of two designated coal silos.

     Engineering and procurement of a fuel handling facility for an independant
     power project (IPP).
     The fuel (bituminous gob) is delivered by truck to a coarse reclaim hopper and a
     fine reclaim hopper. The coarse gob is reclaimed on a 48" variable speed belt feeder.
     The fine gob is reclaimed by a special designed variable speed rotary plow feeder,
     integral with the fines hopper. Both the coarse and the fine material are collected
     on a 36" reclaim tripper belt. This belt terminates in a 6,000 ton capacity storage
     barn. The belt is fitted with a traveling tripper which traverses the operating
     length of the building.
     Material is reclaimed from the storage pile by a traveling scraper-reclaimer rated
     at 250 TPH. This reclaimer traverses the pile length and reclaims material to the
     30" reclaim conveyor. Additionally, provisions are included for emergency reclaim
     by an aboveground dump hopper. The reclaim conveyor is fitted with a belt scale
     and a magnetic separator for tramp iron removal. The reclaimed gob is discharged
     to a vibrating scalping screen with a nominal 4" deck. The +4" material (considered
     refuse) is discharged along with the tramp iron to separate tote bins.
     The through product from the scalping screen is collected in a 20-ton, surge bin
     from which it is fed by twin vibratory feeders to two crushers. Each crusher unit is
     rated at 120 TPH and makes a nominal 1/4" x 0 product. The processed fuel is then
     collected on the fuel bunker feed conveyor/tripper conveyor, which terminates on
     the boiler bunker system. A traveling tripper is provided for bunker filling.
     A control system is provided, which interfaces with the owner-supplied distributed
     control system. The project was completed in approximately 12 months.

Engineering and procurement of a fuel handling/processing facility. This facility
handles both bituminous coal and bituminous coal gob.
The material is handled in twin unloading hoppers, rated at a nominal 30 tons
each. Vibrating feeders are provided for reclaiming. The reclaimed material is
collected on a 36" fuel transfer belt rated at 500 TPH. The material is then
transferred to a 60" high angle elevating conveyor using a flexible belt wall.
This unique conveyor is a special design and is fitted with a service-way the
entire elevated length. The material from the elevating conveyor discharges
to a 36" reversible silo feed belt rated at 500 TPH. This belt discharges material to
either the coal silo or the gob silo. The silos themselves were not in our scope
of supply; however, we did provide the engineering.
Fuel silos are fitted with variable speed, specially designed, rotary plow feeders.
The rotary plow feeders discharge to twin-way feeders which convey the material
to either the BMR or Hammermill crushers for processing. The crushed material
is collected and conveyed to the second high angle elevating conveyor (rated at
120 TPH) for delivery to the bunker fuel bins.
An emergency hopper is provided, suitable for front end loading, and fitted
with an en-masse elevating conveyor for emergency reclaiming.
Ancillaries for this project include exclusive dust collection (particularly in
the area of the truck dump) and heating and dust collection for the BMR and
Hammermill units.
The scope of supply included the supply of low voltage electrical apparatus,
control and instrumentation and control panels. An interface was provided

     Engineering, procurement and construction of a coal handling system and dust
     suppression and collection upgrade at their C.P. Crane Station originally built
     in 1958. Most of our construction occurred during a six week planned shut down
     during the Spring of 1994. The challenge of this project was to plan so that all the
     material, site preparations, equipment and workers were deployed, ready to start
     and finished during the shutdown.
     The scope of the project included replacing conveyor idlers, pulleys, chutework,
     covers, skirts, reducers and motors. It also included modifying the existing silo
     hopper bottom to accept new conveyor feeders. As part of the project the existing
     car dump hoppers were demolished and replaced. A limestone handling system
     with a capacity 6 TPH was also installed. A dust collection and suppression

COGENERATION COMPANY, MT. POSO COGENERATION
PROJECT FLUIDIZED BED BOILER (49 MW)
Engineering design, procurement and construction management services were
provided for construction of a fuel handling system for a 49 MW, coal fired
cogeneration power plant. Work included the design of a truck dump to receive
27-ton capacity, highway trucks with tandem trailers.
The dump is fitted with two vibrating reclaim feeders which reclaim coal at a rate
of 200 TPH and discharge to an en-masse type conveyor which transports the coal
to a silo fill bucket elevator. A rotary drum type magnetic separator located at the
discharge of the en-masse conveyor removes tramp iron from the as-received coal.
The silo feed elevator discharges directly to a 3,000-ton capacity concrete coal
storage silo providing approximately 4.5 days fuel supply. The silo is fitted with
a single, totally enclosed, variable rate vibrating feeder to reclaim stored coal.
Reclaimed coal reports directly to a ring-type granulator crusher which reduces
the 2" x 0 as-received coal to a nominal 1/2" x 0 product required at the boiler feed.
The silo reclaim feeder and crusher are rated at 200 TPH. Sized coal discharges
directly to a reclaim en-masse conveyor which transports the coal to the day bin
fill bucket elevator. Coal is elevated to a point above two 300 ton capacity day bins
and is directed to the appropriate bin via an automatic flop gate located in the day
bin elevator discharge chute. The day bins provide approximately 24 hours of live
storage and are positioned directly above two gravimetric feeders which feed coal
at a metered rate to the boiler. The coal handling and storage system is entirely
enclosed and is provided with a dust collection system designed to maintain
a negative pressure within the system.
The truck dump is totally enclosed and fitted with a dry fog type dust
suppression system to minimize fugitive dust emissions. A programmable
logic controller provides the control means for automatically receiving,
storing and reclaiming coal.

    R&S prepared a feasibility study that included investigating the coke conveyors,
    the coke crushing, truck loading and washing, pumping the pit sumps, and
    removing the coke solids from the recycle cutting water.
    At the conclusion of the study R&S was awarded the engineering, procurement
    and ultimately the construction.
    A big concern was designing a layout that could be built during normal coker and
    refinery operations. R&S was able to construct 90% of the project pre turn-around
    as planned and completed the last 10% during the turn. Start-up was completed
    prior to the scheduled completion.
    The major equipment and construction involved with this project included:
    • Replace the 30' long turbine sump pumps with submersible sump
      and modify the coke sump pits to better settle
    • Fabricate and install a second mobile crushing unit as a back-up to
      the existing mobile crusher
    • Upgrade the existing mobile crusher to match the safety and automation
      levels of the new crusher
    • Construct two new conveyors and a fully enclosed transfer station including
      new directionally adjustable chute work, a cyclone dust removal system,
      and a transfer building.
    • Fabricate and install a new 500 ton capacity pant leg load-out hopper.
      The hopper includes two automatically actuated knife gates for loading
      the trucks, a 104' long truck scale, a pulse jet bag house dust collection
      system, and future support and access for additional conveyors should
      a new storage facility be required.
    • Install a new PLC system that fully automates the hopper level and truck
      loading and provides feedback to the coke control room and the crane operators
      from which they can make real time production decisions. The truck driver
      remains in his cab and is only required to select his final destination to activate
      the automated loading. The knife gate is activated in such a way as to assure
      loading to within 200 pounds of maximum load.
    • Fabricate and install a new automated truck wash system.

GOLDEN EAGLE REFINERY, MARTINEZ, CALIFORNIA

Engineering and procurement for the coke handling system.
Tesoro Refining and Marketing Company (Tesoro) has implemented major
modifications to their coking facility at the Golden Eagle Refinery located
at Martinez, California, an essential part of which is the Coke Handling System
for loading coke product into trucks for transport to market.
The system incorporates two switchback conveyors, with a transfer station
at the switchback. The conveyors receive coke from a feeder/breaker and deliver
the product to either of two twin bolted steel loadout silos situated above dual
drive-through loading lanes.
The entire facility is enclosed for dust control. In order to circumvent
the ventilation problems associated with steam, dust and visibility inside
a conventional enclosed conveyor gallery, the conveyors are enclosed locally
with light gauge material around the carry and return belts; leaving the
walkways open for maintenance and ventilation.
An automated wash-down system enables cleaning of the enclosed conveyors
with spray nozzles located inside the enclosure and pipe drainage to sump pumps.
The two loadout lanes (one below each silo) are fully automated. RF readers
and weigh scales communicate with a PLC to control the silo discharge slide
gates for loading trucks within plus/minus 200 lbs.
The trucks exit the enclosed loading lanes through an automatic wash station
to remove latent dust prior to entering the State road system.

handling system; the contract was awarded by Worley Parsons.
Limestone is received from trucks with a capacity of 20 to 40 tons at the
outdoor limestone storage pile.
The limestone can be reclaimed by one of two pieces of equipment. The first option
is to push the limestone by end loader to the feed end of the limestone reclaim
feeder, a chain conveyor provided by Joy Mining Machinery Corporation with
a capacity of 125 tons per hour. The limestone reclaim feeder feeds the limestone
onto a crusher feed conveyor with a capacity of 125 TPH designed and supplied
by R&S. This conveyor feeds the crusher building. At the head end of the crusher
feed conveyor, a magnetic separator collects any tramp iron that may have found
its way into the as-delivered limestone. The second option is to use an end loader
to dump the limestone into the emergency limestone reclaim chain conveyor,
a chain feeder that was designed and manufactured by R&S. This feeder also
has a capacity of 125 TPH. The emergency limestone feeder feeds the limestone
onto the emergency crusher feed conveyor. This conveyor also feeds the crusher
building but bypasses the crusher and feeds the limestone directly onto one
of the two overland conveyors.
At the crusher building the limestone is reduced to a size of 1/8" x 0 by a Penn
Crusher hammer mill and is then discharged into a two-way diverter gate and
then onto one of two limestone overland conveyors as provided R&S. A dust
collector is provided for the feed onto the overland conveyors to pick up any
fugitive dust from the discharge of the limestone onto the overland conveyors.
The limestone overland conveyors have a capacity of 125 TPH and run to the
top of three limestone storage silos and discharge onto one of two limestone
cross conveyors. The cross conveyors also have a capacity of 125 TPH and
are used to distribute the limestone into the three silos.
The limestone can be reclaimed from the silos by the use of a rotary silo discharger
that was provided by Decker Industries. The silo dischargers feed the limestone
onto a weigh belt feeder which then feeds the limestone into one of three ball mills
for further processing.

     to a 36" unloading conveyor and transported at 900 TPH to a 4000 ton
     concrete storage silo.
     The limestone is reclaimed from the silo via (2)-36" variable speed belt
     feeders operating at 30 to 300 TPH each.
     Each belt feeder transfers to a 30" limestone transfer conveyor operating at
     300 TPH up to (2)-400 ton steel surge bins in TVA’s limestone preparation plant.
     Each surge bin feeds a TVA supplied weigh belt feeder. Limestone can also
     be fed to the transfer conveyors with a front end loader via an emergency
     hopper and conveyor.
     Bin vent filters were provided for the silo and also for each surge bin.

Engineering, procurement and construction of a 320-460 MTPH R&S Coal Flo®
Thermal Dryer System.
The system is capable of handling 460 MTPH of J-Seam coal at 10.84% moisture
and 320 MTPH of Upper Seam at 12.08% moisture. The process results in coal
at 6% total moisture.
While evaporating approximately 26 MTPH of water, the system meets MWLAP
requirements of 7.08 TSP per second and SO2 emissions of 5.6 GPS (based on the
alkalinity of the water and sulfur content of the coal).
The coal to be dried is fed by conveyor into the feed control bin and discharged
to the dryer bed with an automatically controlled gate.
On the dryer bed the coal is fluidized by the upward stream of hot gases and dried
almost immediately then settles into the discharge hoppers.
As the drying gases are pulled through the coal bed, heat and velocity are quickly
dissipated.
Gases leaving the drying chamber pass through cyclone dust collectors and

    NORTH ROCHELLE MINE, GILLETTE, WYOMING

    Engineering, procurement and construction of a 6,000 TPH coal handling, storage,
    and train loadout system with overland conveyor.
    The coal handling system is designed to receive raw coal from 240-ton dump trucks
    with material size of 8" x 0". The receiving hoppers have a capacity of 535 tons.
    The hoppers feed two feeder breakers rated at 2,000 TPH each that feed the
    transfer conveyor to the crusher station. A 4000 TPH roll crusher reduces
    the coal to 2" x 0". The coal is then fed to a 7,000-foot long overland conveyor
    rated at 4,000 TPH.
    The overland conveyor conveys the coal to a traveling tripper conveyor at the
    coal storage barn. The traveling tripper discharges the coal to the slot storage
    coal barn with a capacity of 50,000 tons.
    Coal is reclaimed from the storage barn with 26 vibratory feeders with a rated
    capacity of 800 TPH each, of which 10 are variable rate.
    The vibratory feeders feed the loadout conveyor rated at 6,000 TPH, which in turn
    feeds, the loadout system.
    The batch weigh dual hopper loadout system incorporates a 300-ton surge bin

Coal Crushing and Handling Facility
Coal is received from off-road trucks with a capacity of 100 to 220-tonnes at the
truck dump hopper. The hopper is located at the western end of the stockpile and
consists of a single 300-tonnes hopper, with main dump face. The truck dump
area will have a secondary side dump face at a future date. The hopper discharges
through a feeder breaker to the sizer station feed conveyor. The feeder breaker
reduces the received coal from 500 mm to 200 mm x 0 mm at an average capacity
of 2,000 MTPH (2,500 MTPH peak). At the sizer station the coal is further reduced
to 50 mm x 0 mm, and then it is conveyed and discharged to the stockage pile with
a traveling tripper. The storage pile has a total capacity of 200,000 tons.
A reclaim tunnel under the full length of the stockpile houses the reclaim conveyor
and includes five equally-spaced draw-down hoppers with coal valves and stockpile
activators. The coal is discharged directly onto the reclaim conveyor at an
average capacity of 4,000 MTPH (4,500 MTPH peak). Downstream of each
reclaim discharge valve, a belt scale respectively controls the valve coal feed rate,
while indicating total metric tons. Each coal valve also has an average capacity
of 4,000 MTPH (4,500 MTPH peak). Diverse coal stockpiles can be blended via
the use of these coal valves. The reclaim conveyor includes a sampling system

AMAX COAL COMPANY

WABASH MINE , KEENSBURG, ILLINOIS

Engineering, procurement and construction of a 1,500 TPH coal preparation,
storage and reclaim facility.
The plant was built at an existing mine site, which previously operated separate
fine and coarse coal cleaning plants. The new facility replaced all existing cleaning
facilities while increasing total plant capacity. The existing operations were kept
on stream during the construction phase.
The project consisted of the installation of a new rotary breaker circuit, raw coal
storage facilities (twin open storage piles with transfer conveyor and concrete dust
tube). Reclaim to the new preparation plant was accomplished by in-line vibratory
feeders, feeding the plant feed belt housed in a concrete reclaim tunnel.
The clean coal from the new plant tied into the existing clean coal storage system.
Refuse was transported to the existing refuse bin.
Plant circuitry consisted of wet screening using “banana” screens for separation
to the coarse circuit (which uses twin heavy medium vessels). The intermediate
fraction is cleaned in heavy medium cyclones while the 16 mesh x 100 mesh
material is cleaned in conventional spiral circuit. The -100 mesh material is
thickened in a static thickener and dewatered on seven 3-meter belt presses.           The overall project was completed
This plant design is unique in that screen bowl centrifuges are used to dewater        in approximately 14 months.

     MINGO LOGAN COAL COMPANY

     BLACK BEAR PREPARATION PLANT, MOUNTAINEER MINE,
     GILBERT, WEST VIRGINIA
     Engineering, procurement and construction of a 1,600 TPH coal preparation plant
     and material handling facility. This project is one of the largest coal preparation
     facilities in North America and encompasses extensive material handling, storage,
     blending and reclaim facilities in addition to the preparation plant.
     The location, together with the distance between the mine face and the loadout,
     presented unusual engineering challenges.
     The raw coal was received at the mine site and stored in a 6,000-ton silo prior
     to being conveyed overland on a 2-flight transfer conveyor system to the plant
     site. At the plant site, additional unloading facilities were provided, consisting
     of truck dumps and open storage. The combined R.O.M. product was screened
     and passed through a rotary breaker, prior to storage in three 6,600-ton raw
     coal storage silos. Overflow provisions are included in the silo along with
     emergency reclaim provisions.
     The preparation plant consists of two independent 800-ton circuits. Separate
     surge bins are provided ahead of both circuits to guarantee uniform splitting
     of the plant feed. Each circuit consists of wet screening of the raw coal into three
     fractions: a 6 x 3/8 fraction for processing in the coarse vessel circuit, a 3/8 x 16
     mesh fraction for the heavy medium cyclone circuit and a 16 mesh x 0 fraction
     which is the coarse deslimed product.
     The 16 mesh x 0 material is classified at approximately 65 mesh with the
     overflow reporting to a spiral circuit and the underflow reporting to single stage
     froth flotation. Clean coal dewatering is accomplished by the use of conventional
     vertical centrifuges for the vessel. Horizontal screen bowl centrifuges are provided
     for the combined spiral circuit and froth circuit products.
     The water clarification and magnetite control circuits are common to both the
     A and B circuits of the plant. The clean coal is collected on a single conveyor with
     a tail drive located in the coal preparation plant and transported to the three clean
     coal silos, approximately 1-1/2 miles down stream. The three clean coal silos are
     equipped with high rate vibrating feeders that feed the 4,000 TPH loadout system.
     Plant refuse system consists of a loadout bin with surplus ground storage for the
     +100 mesh refuse. The -100 mesh refuse is thickened and ponded in a settling
     basin/aquifer system, located approximately half way between the plant and
     the loadout facility. Fresh water rate to the preparation plant, as well as all fire
     protection and ancillaries, is included in the scope of our supply.
     This particular project had unusual time restraints. The plant itself was
     operational in approximately 11 months with the total facilities operable
     in approximately 13 months.

KENTUCKY CRITERION COAL COMPANY

DEANE, KENTUCKY

Engineering, procurement and construction of a 750 TPH cleaning plant and raw
coal facility. A few years prior to the installation of this plant, Roberts & Schaefer
had constructed a high rate train loadout system fed by open storage pile and
stacking conveyors. An extensive truck dump and crushing station were provided.
The 750 TPH plant and raw coal handling facility were added and tied into the
previously supplied system. The new raw coal storage consisted of a unique high
wall dumping facility with lateral feed of the dump area. It was provided with
guide rails and concrete curbing. A pocket containing a feeder breaker system was
installed at the dump area of the high wall to crush oversize material obtained
from some of the local strip pits.
At the bottom of the high wall, an above grade reclaim tunnel was installed
housing two reclaim belts, fed by vibrating feeders. This system provided
a myriad of blending options. Reclaim material is crushed and then by-passed
to the existing loadout facility or fed to the new preparation facility.
The preparation plant consisted of wet screening on double deck raw coal screens
ahead of a single 20' heavy medium vessel. No pre-wet screens were included in
this plant. The intermediate size was split at 3/8". The feed to the vessel circuit
is 6" top size x 3/8". The 3/8" x 0 slurry is deslimed at 1 mm ahead of the heavy

     MAPCO COAL COMPANY

     PONTIKI MINE , LOVELY, KENTUCKY

     Engineering, procurement and construction of a 500 TPH plant addition.
     This project required a major scheduling and coordinating effort. The addition was
     designed to increase existing plant capacity, while keeping the facility operable
     during the erection and installation of the additional equipment.
     Roberts & Schaefer Company elected to add a heavy medium cyclone circuit in
     a size fraction which maintained the feed rate to the existing vessel circuit, and
     simultaneously reduced the feed to the existing heavy medium circuit. This was
     effected by selective screening raw coal ahead of the existing circuit. Additional
     rework was required on existing equipment such as replacement of the existing
     heavy medium vessel, and modifications to the existing screening facilities.
     Also included was a complete control system incorporating both the existing
     and new facilities.
     The existing water clarification circuit and static thickener were refurbished
     so they would be adequate for the increased capacity. The changes were made
     by the use of magnetic separation tailings as rinse water for the heavy medium
     rinse screens.
     Existing material handling facilities for raw coal and clean coal were upgraded
     to accommodate the additional capacity.
                                                                                          This project also had an unusual time

BLUE RESOURCES, INC.

J. W. CORNETT PREPARATION PLANT,
LEATHERWOOD, KENTUCKY
Engineering, procurement and construction of a 1,250 TPH preparation plant
and coal handling facility. This project was unique because of the extreme site
constraints, resulting from mountainous terrain.
Raw coal was received from two truck dump areas which obtain coal from two
separate seams. A storage and reclaim facility for raw coal was designed to permit
coal blending from the two seams. The screening and breaker station was provided
to make a 6" x 0 product, which is fed to the preparation plant. Raw coal is wet
screened with a combination incline and pre-wet screens to make a 6 x 4" feed
to a heavy medium low flow bath circuit. The 1/4" x 0 raw coal is partly deslimed
over sieve bends and passed through super-scalping units for refuse scalping
ahead of the raw coal cleaning circuit. The raw 1/4" x 0 overflow from the super-
scalping circuit is screened in high refuse capacity double deck Deister tables.
The 28 mesh x raw coal is classified at approximately 100 mesh; the classifying
cyclone underflow reports to a spiral circuit. The cyclone overflow is delivered to
the water clarification circuit, which used a 120' diameter high capacity thickener.
The clean coal products and refuse products are mechanically dewatered. A stoker
product is made from the bottom deck of the low-flow circuit clean coal screens.
The primary rejects from the low-flow circuit are rewashed in a secondary vessel.
A middlings product is made from the secondary vessel circuit. The clean coal
stoker and the middlings product are collected and transported to a series of open
storage piles with transfer belts, gates and lowering tubes which effect complete
flexibility for product storage. The entire storage system is located over a common
reclaim tunnel, approximately half a mile in length.
Vibrating feeders and intermediate belt scales allow for blending. The reclaimed/
blended coal is transported on a high capacity reclaim belt to a loadout system.
This loadout system is unique in that it adds a separate system for stoker batch
weighing, to the conventional batch weighing concept.

     BAILEY MINE COAL PREPARATION PLANT,
     ENON, PENNSYLVANIA
     As an addition to the original Bailey Mine complex, initially installed by Roberts
     & Schaefer in 1983, we designed, engineered, procured and installed a large
     capacity facility. This plant addition combined with the original plant to make
     the Bailey Preparation Plant the highest annual production facility in North
     America. Plant input often exceeds 3,200 TPH with one of the highest availability
     ratios in the industry.

     The installation consists of a second stream raw coal handling system with            so that it was operating at full capacity in
     scalping screens and rotary breaker. Breaker rejects are gravity fed to the           11 months from date of award.
     existing loadout bin. The 4" x 0 breaker through product is the plant feed
     at a nominal 1,600 TPH.
     The plant circuitry consists of heavy medium vessel circuit for the 4" x 3/8" raw
     coal with the 3/8" x 0 wet screened product deslimed at .5 mm. A heavy medium
     cyclone circuit is used for the 3/8" x .5 mm fraction. The .5 mm x 0 raw coal is
     cleaned in two stage hydrocyclones with the hydrocyclone overflow classified
     at 100 mesh. Froth flotation is provided for the 100 mesh x 0 material. Clean
     coal products are centrifugally dried for the plus .5 mm fraction.
     The froth concentrate is dewatered in vacuum filters. The mechanically dried clean
     coal product in the size range of 3/8" x 0 is then collected and transported to the
     thermal dryer. The thermal dryer (the largest in the United States) was designed
     and furnished by Roberts & Schaefer. The dried clean coal and dewatered refuse
     are conveyed to the existing facilities.
     The project had unusual physical and time constraints since the existing complex
     had to be kept in operation essentially around the clock during construction
     of the new facilities. The commitments for coal sales by the client required
     an accelerated schedule.

     Roberts & Schaefer Company was selected to furnish the complete project
     management, permitting, detailed engineering, procurement and construction
     management services for a coal storage terminal facility. This facility will assemble
     and store coal for ship loading and transhipment for the Norfolk & Western
     Railway Company. The ground storage terminal system will initially provide
     a facility capable of storing 1.63 million tons of coal on the ground with an annual
     throughput capacity of 8 million tons. The final phase of the project will increase
     the ground storage capacity to approximately 8 million tons with an annual
     throughput capacity of 40 million tons.
     The proposed facility will receive coal by rail, transfer the coal to ground storage
     at the design rate of 6,000 TPH. This will be done through an automated high
     capacity tandem rotary car dumper, conveyors, surge bins and automated
     stacker/reclaimer. The coal will be stored on a surface constructed to prevent
     contamination of the ground water table, as well as allow various trans-shippers
     to have their coal stored and reclaimed without contamination from other grades
     of coal. The coal handled will be primarily of metallurgical quality. During
     operations, the environmental conditions of wind, precipitation and humidity will
     be monitored through a computerized system to determine the effects the weather
     will have on the stored coal. An automatic dust suppression system is provided,
     and controlled by the computerized monitoring system. It is used to protect the
     environment from air borne dust from the ground storage and conveying systems.
     Upon request by the trans-shipper, coal will be reclaimed from storage at a design
     rate of 6,000 TPH by the stacker/reclaimer. The stacker/reclaimer is fitted with
     a 210' boom arranged to deliver reclaimed coal via yard conveyors to two over
     the track loadout silos. Each silo is capable of storing 11,500 tons of coal. The
     coal will be discharged from the silos through a unit batch weigh system at the
     nominal rate of 8,000 TPH. From there it will go directly into 220 car unit trains
     for transporting to Norfolk Southern Corporation’s Lamberts Point Terminal for
     loading into ships.

GEOVIC

NICKEL – COBALT PROJECT, NKAMOUNA, CAMEROON

Roberts & Schaefer conducted an Optimized Feasibility Study to investigate
all areas for lowering costs while concurrently advancing front end engineering
design (FEED); reducing risk and establishing major construction start and
completion dates.
Some of the challenges facing the project team for the feasibility study are, limited
local electrical supply, and very basic services and supplies. There is no telephone
service, airstrip, or approved heliport, and only rudimentary medical facilities.
This is extremely demanding project and one of the first of its kind in this part
of the African continent, apart from the above mentioned challengers there are
many other issues to be overcome such as skilled labor to build & operate the
mine and processing plant.
There is a huge potential of future mines within the resources rich region, the joint
venture team are very mind full of getting the project right to pave the way for
other such ventures.
The Geovic Project will be executed within a joint venture structure comprising
Roberts & Schaefer, Bateman International Projects and Group 5 Projects.
The Geovic Project is the first of seven potential cobalt-nickel-manganese
deposits to be developed and it is estimated to contain 53 million tons of proven
                                                                                        Roberts & Schaefer has provided the
and probable ore reserves at average grades of 0.24% cobalt, 0.72% nickel and
1.22% manganese.

The ore is concentrated by simple sizing and upgraded to 0.7% cobalt, 1.0% nickel
                                                                                        all phases of precious and base metal
and 3.5% manganese prior to processing. The project includes a shallow open pit
mine, ore concentration facilities and a 2,000 metric ton per day process plant.
                                                                                        processing facilities and crushing plants.

NEWMONT GOLD COMPANY, HEAP LEACH CRUSHING
PROJECT, CARLIN, NEVADA
An engineering feasibility study was completed to develop the arrangement
and capital cost for a new heap leach crushing and conveying facility at Newmont
Gold Company’s Gold Quarry Mine near Carlin, Nevada. The final report included
drawings and a cost estimate in a form suitable for presentation to the Board
of Newmont Mining Corporation. The facility consisted of a truck dump station
arranged with a 42" x 65" gyratory crusher, fitted with an under crusher belt
feeder to deliver 6" x 0 ore to an overland conveyor system. The conveying system
allowed for the future addition of secondary crushing. Cement addition and
agglomeration was accomplished through conveyor transfer stations prior
to the ore reporting to a radial stacker and storage.

    ALASKA GOLD COMPANY (NOVAGOLD)

    ROCK CREEK GOLD FACILITY, NOME, ALASKA

    Engineering and estimating services to provide input to the feasibility study for
    the Rock Creek Project, a grass-roots gold facility to be located near Nome, Alaska.
    Plant design was based on processing 7,000 metric tons per day (t/d) of gold ore
    for approximately four years. The processing plant consisted of a conventional
    carbon-in-leach (CIL) and electrowinning recovery circuit.
    Run-of-mine ore is crushed in a primary jaw crusher, a secondary cone crusher,
    in two tertiary crushers and subsequently conveyed to a fine ore stockpile.
    Ore from the stockpile is reclaimed and fed, along with water, to a single ball mill.
    The ball mill operates in closed circuit with cyclones; coarse material in the
    cyclone underflow returns to the ball mill for further grinding, and cyclone
    overflow is processed in gravity concentrators and in a flash flotation cell.
    Gravity concentrate, containing relatively clean gold, is refined into doré
    bars on site.
    Gravity tailings feed the flash flotation cell and flotation tailings feed
    a high density tailings thickener.
    Tailings thickener underflow is pumped to a tailings disposal area and
    thickener overflow is recycled to the milling circuits.
    Flotation concentrate, combined with gravity middlings, feeds a carbon-in
    leach (CIL) circuit where gold is dissolved with cyanide and adsorbed onto
    activated carbon.
    CIL tailings, free of gold values, is conditioned with chemicals in an agitated
    tank to detoxify residual cyanide and pumped to the tailings thickener.
    A pressurized strip circuit will desorb gold from the loaded carbon into
    a concentrated solution, and the gold is recovered from the concentrated
    solution by electrowinning onto steel wool.
    Gold-loaded steel wool is smelted with fluxes to produce gold bullion.

OMG APEX

TUNGSTEN RECYCLE PROJECT, ST GEORGE, UTAH

Engineering for a new Crystallizer Circuit to increase production; R&S had
worked with OMG Apex previously on other upgrade projects.
The scope of the project included:
• Conveyor
• Dryer
• Feeder modifications
• Reactor modification
• Crystallizer #3
• Filter Feed Tank
• Belt Filter
• Receiver tank silo
• Bag house dust collector
• Piping to integrate Crystallizer #3 with #1 and #2.
• Electrical power and PLC control architecture
• Platforms, access stirs, access ladders, product and maintenance lifts
• All process, mechanical, structural, electrical and control engineering
OMG Apex stored the magnesium scrap in their yard where it absorbed moisture
awaiting processing. Their scrap deliveries were inconsistent and they were forced
to purchase and store material to assure a consistent feed to the process.
As a result of process fine tuning they were able to increase the slurry feed which
required additional process equipment to convert to final product.
In order to properly dry the scrap material R&S designed a feed conveyor to a
dryer vessel modified for this purpose, and the support so the vessel could rotate.
The dry material was loaded to a feed hopper which fed the calciner. The calciner
could process at a higher rate since energy was not required to dry as well as
break down the tungsten.
The increased process flow required a third crystallizer which was tied into
crystallizers 1 and 2. A filter Feed Tank, Belt Filter, concentrate tank, agitator,
centrifuge, and product silo were added to finalize the recovery of the tungsten.

    HEMATITE FLOTATION CONCENTRATOR,
    HUMBOLDT, MICHIGAN
    Complete engineering, procurement and construction management services were
    provided to convert an existing hematite flotation concentrator to a 2,000 TPD
    gold ore processing facility.
    The project included the addition of a new two-stage crushing plant with a jaw
    crusher, a cone crusher and associated screening and conveying equipment.
    Existing fine ore storage bins were reused to store crushed ore to serve each
    of two grinding circuits consisting of 900 HP ball mills in closed circuit with
    20" cyclones.
    The remainder of the mill equipment included rougher and cleaner flotation,
    a cyanide leach circuit, static thickeners and drum and disk vacuum filters.
    The leachate was clarified in a pressure leaf filter prior to deaeration ahead
    of zinc dust precipitation. The facility utilized the Merrill-Crowe zinc
    precipitation process to produce dore’ bullion.
    Engineering services included all design phases associated with both the crushing
    plant and the mill including determination of suitable environmental mitigation
    measures, development of process flow sheets, P&ID and equipment specifications
    and selection.
    All electrical power and control design was also provided. Conversion of the
    existing mill to process gold ore stressed evaluation of existing equipment
    and the reconditioning and re-use where suitable.
    Re-use of existing equipment required detailed evaluation of facility design
    parameters. This was necessary in order to match as closely as possible the
    equipment available to that required by the process, and to provide an efficient
    operating system at the lowest possible capital cost.

ILLINOIS CENTRAL RAIL

MARINE TERMINAL, ST. JAMES PARISH, LOUISIANA

Roberts & Schaefer Company provided engineering, procurement, startup and
construction management services for the Illinois Central Rail Marine Terminal
(ICRMT) in St. James Parish, Louisiana. Several different products are being
handled at this facility, including Coal, Pet Coke, Met Coke, Iron Ore Pellets,
and DRI. The facility provides iron ore pellets to the neighboring DRI facility
for processing, which then conveys the processed DRI back to the handling facility
for loading onto ocean vessels, river barges or trains. The project consisted of the
following major systems:
1. Traveling Grab Unloader to unload river barges or ocean vessels
   of Met Coke or Iron Ore Pellets at a rate of 3000 TPH to a traveling
   stacker for storage or directly to the DRI processing facility.
2. Traveling Shiploader to load ocean vessels with DRI (1100 TPH),
   Pet Coke (1100 TPH), or Coal (3000 TPH).
3. Barge Loader (supplied by R&S) to load river barges with DRI (1100Tph)
   or Coal (1700 TPH).
4. Rotary Car Dumper to unload Coal (3000 TPH) or Pet Coke (3000 TPH)
   to the traveling stacker for storage or onto conveyor belts for direct loading
   to ocean vessels or river barges.
5. Unit Train Batchweigh Loadout to load rail cars with DRI or Pet Coke.
6. Traveling Stacker to stockpile Iron Ore, Coal, Pet Coke or Met Coke.
   Reclaiming was accomplished by front end loaders feeding portable
   conveyors or dozer traps.
Due to the varying densities of the materials, variable frequency drives were
utilized on many conveyors to convey the materials at the proper rate. Also, several
conveyors were used to convey material both inbound and outbound, therefore they
had to be reversible. There is over 16,000' of conveyor on this project. The entire
process is controlled by an Allen Bradley programmable logic controller (PLC)
and human machine interface (HMI) terminal in a control tower which also
communicates with other PLCs aboard the machines. The PLC automatically
selects the proper conveyor speed based on the material being conveyed. The
control room is situated on top of a transfer tower to provide the operator with
a vantage point to be able to oversee the entire system.

     Engineering, procurement and construction for the addition of a hearth layer
     system for pellet machines No. 11 and No. 12 at the then inactive Silver Bay
     processing facility in Silver Bay, Minnesota.
     This process was initially designed to provide taconite pellets. The installation
     included in this project increased plant capacity and coordinated the reactivation
     of the vessel.
     Pellets for the hearth layer are obtained from the pellet discharge chutes on ma-
     chines No. 11 and No. 12. Chutes are provided with a diverter gate to direct mate-
     rial to a process transfer conveyor or to individual collecting conveyors
     which transfer to the first green pellet elevating conveyor.
     The first green pellet elevating conveyor distributes to an external transfer tower
     to a second transfer conveyor. This conveyor elevates the material to three transfer
     conveyors that feed a combination feed chute and diverter gate which in turn
     recycles the material to either machine No. 11 or via an additional transfer
     conveyor to machine No. 12.
     The entire system is fitted with bag house type dust collectors. A complete process
     control system was provided, which is tied into the existing facility. As part of the

POSVEN

HOT BRIQUETTED IRON PLANT
PUERTO ORDAZ, VENEZUELA
Engineering and procurement for the ore/pellet feed and blending system
and HBI (Hot Briquetted Iron) stockpile, screening and train loadout system
at Posven HBI Plant.
The process consists of an iron ore/pellet feed system from either an open
ore/pellet reclaim hopper or a pellet feed conveyor system. The ore/pellets are
stored in separate bins which have weigh belt feeders on the discharge of each
bin. The weigh belt feeders then feed double deck screens. The oversize lumps
(+38mm) are conveyed to a stockpile. The screened fines (-6.35 mm) are conveyed
to two ore/pellets fines bins which provide truck loadout. The sized (+6.35 mm to
-38mm) ore/pellets are then conveyed in a controlled ration of ore/pellets/HBI fines
to the reactor reduction system and briquetter machines. The briquettes are then
conveyed along product cooling conveyors to two screens. The screened HBI fines
are then transported by conveyor to an HBI fines bin in the ore/pellet blending
system which are then sent back through the process. The overs from the screens
are conveyed to either the train loadout system or stockout pile.
The use of pocket conveyors and standard conveyor systems are used throughout
the system due to space considerations. The process also included dust collection,
cooling water spray, sampling and dust suppression systems. The entire system
is controlled through a programmable logic control (PLC) system and human
machine interface (HMI) computer terminal.

SGS CANADA

OIL SANDS EXTRACTION PLANT, FORT MCMURRAY,
ALBERTA, CANADA
Mineral: Oil Sands
Engineering and procurement services for the material handling system,
oil extraction skids and froth treatment skids for their pilot plant facilities.
SGS is a world renowned third party testing services company. In an effort
to establish themselves in the oil sands industry, started building their pilot
plant for first oil sands client , Synenco Energy in 2007.
Synenco contracted SGS to provide testing facilities to test their patented spiral
drum extraction technology using the ore from their oil sands lease. SGS contracted
R&S to engineer and procure the material handling system and work with Synenco
to develop a pilot scale version of their extraction drum.
The 2 MTPH material handling system consisted of a crushing station which
reduced the ore to 2" minus. It is then conveyed to a metering station that uses
an apron feeder to meter the ore going into the extraction area. Once the sand
has been separated from the oil, it is removed by the tailings stacking conveyor.
The crushing and metering stations are all located in the ore storage building
that is maintained at -15° C year round.
The extraction system involved the patented extraction drum and various
process skids consisted of tanks, pumps, floatation columns, thickeners
and instrumentation.
Upon successfully delivering the first job, R&S was sole sourced to reconfigure
the extraction process equipment, design and deliver 3 froth treatment skids
for SGS’s second customer Teckcominco/ UTS.
The extraction drum drive was completely redesigned and the froth treatment
skids included a CCD (counter-current decantation) system, TSRU (tailings
solvent recovery unit), and a SRU (solvent recovery unit). separate from the
railcar loadout system.

     KRUPINITE CORPORATION

     MODULAR PRODUCTION PLANT

     Mineral: Tantalum and Niobium
     Detailed Design & Engineering (Construction to follow when location is found)
     Roberts & Schaefer Company worked with a newly formed company, Krupinite
     Corporation to design and build a modular tantalum/niobium production plant
     with throughput of 100 metric tons per month, to verify and refine the new
     recovery process for commercialization. To date the design engineering has
     been completed and the construction of the modules is awaiting the owner’s
     selection of a location to place the new facility.
     The new technology, called the Krupinite Process, has been developed to recover
     tantalum and niobium from ores, wastes, process residues, concentrates, and
     other similar materials. Although tantalum and niobium recovery processes
     are not new, present methods use highly corrosive and hazardous reagents and
     produce harmful waste streams. For example, the procedure currently being
     used consists of the following basic steps:
     1. Dissolving tantalum and niobium from materials with hot hydrofluoric acid.
     2. Separating the liquid (dissolved tantalum / niobium) from the solids.
     3. Precipitating the metals from the aqueous solution with ammonia.
     4. Calcining the precipitate to produce tantalum and niobium oxides.
     The main disadvantage of the old technology is that it produces a large amount
     of wastewater containing ammonium fluoride and a solid waste containing
     fluorides and residual hydrofluoric acid. Elaborate and expensive neutralization
     and precipitation steps are therefore required before any of these waste streams
     can be disposed of. Another disadvantage is that fresh hydrofluoric acid has
     to be added on a continuous basis to make up for the acid compounds lost
     to the waste streams.
     The Krupinite Process drastically reduces the volume of hazardous waste streams
     generated by the current processes. The steps involved in this new process are
     similar to current procedures except that in Step 1, the metals are dissolved in
     a heated solution of ammonium fluoride instead of hydrofluoric acid. Fluoride
     ions that would normally end up in the waste streams with present extraction
     procedures are instead, through a series of scrubbers and condensers, recovered,
     regenerated and recycled into the process. In Step 3, ammonia used to precipitate
     the metals is also recovered, regenerated and recycled into the process.
     Additionally, waste piles from existing operations can serve as the feedstock in the
     recovery of contained metal values without disturbing additional land by mining.
     Reclaiming the nonrenewable resources such as tantalum and niobium would also
     reduce the volume of existing waste piles.

The project involves three stages of crushing/screening utilizing Sandvik and
Metso primary jaw crushers and Sandvik and Metso secondary and tertiary
cone crushers to provide several different grades of aggregate product.
Screening is accomplished with Powertec and Fintec screens.
The storage yard consists of several product stock-piles; reclaim system and
a truck weighing scale and a loading hopper.
An obstacle to efficient plant operation was the severely limited siding availability
for unit train loading.
R&S was awarded a turnkey contract to build an innovative train loading
system developed by R&S that permitted the loading of up to 16 shuttle unit
trains (25 each) per 24 hours.
The train loader is a traveling tripper type using a reversible feeder at discharge
to direct material to cars on either side of central belt.
A PLC system controls the loading via belt scale, automated bin gates and provides
servo drive control of the tripper. System loads a 25 car shuttle in 90 minutes.
The plant and train load-out became operational in early 2009; the plant operates
24 hours a day at a rate of 4 million tons annual throughput.

CALAVERAS CEMENT COMPANY

QUARRY CRUSHING SYSTEM, TEHACHAPI, CALIFORNIA

Roberts & Schaefer Company was awarded the engineering services for a new
Crushing Circuit Upgrade project.
The main function of the new construction was to connect a new owner
provided Hazemag crusher with the existing cable supported overland conveyor.
Within this circuit, the owner desired to install an in line real time atomic
analyzer and to separate the useful limestone material from the undesirable
decomposed granite (DG).
In order to get a proper silica additive, some of the DG had to be added
to the limestone which was accomplished automaticallyfrom a feeder at the DG
hopper. R&S was in charge of all civil work on the site, the structural, mechanical
and electrical engineering for the conveyors, screens and bins, the MCC/generator
building, and the analyzer building.
The Hazemag crusher had a minus 4" vibratory screen prior to the crusher to
separate the DG (99% minus 1") and undersized limestone. In order to process the
screened material we provided a 48"conveyor at the unders screen, a 90° transfer,
and a 36" conveyor to the top of a 3 deck screen. The screen separates the smaller
limestone which is put back on the main conveyor via rock box chute work. The
remaining DG falls in to a pant leg hopper. One leg automatically blends DG back
in to the main product chute, via a feeder belt, based on signals from the analyzer.
The other leg feeds a stacking conveyor which discharges near the DG waste pile.
The plus 4" material is fed through the Hazemag crusher and is discharged
on to a 48" product conveyor. This conveyor feeds a load cell supported controlled
feed bin. In order for the analyzer to produce accurate results, consistent feed
is required. The feeder conveyor under the bin automatically adjusts the feed
on the belt going through the analyzer. The final product is transferred to the
existing overland conveyor via a transfer station. The transfer station includes
an emergency flop gate to direct material to the ground in case there is a
disruption on the overland conveyor.

surge bin.
Downstream from the new mill circuit addition, a 30" lime transfer conveyor
returns the 170 TPH coal and transported lime to a crusher feed belt. The
material is passed through a railroad crusher to make a nominal 3/4" x 0 size.
This material is delivered to a 108-ton storage tank. The material from the
storage tank is reclaimed by a pebble feeder which discharges to the mill
storage bin.
The product collects in the mill storage bin and is now fed to two Whizzer
400 HP mills, complete with exhausters and oil pumps. The product from
the air-swept Whizzer mills is collected in two independent cyclone circuits;
each cyclone discharging to a separate 720-ton tank. A common dust collection
system is used for the two cyclones. The dust collection product discharges
to a third 720-ton tank or via the 24" line screw conveyor to a 600 ton,
150 mesh storage tank.
The final product collects in a total of six storage tanks for the various sizes.
Truck loading spouts are provided for each tank, in addition to 24" loadout
screws for conveying the material to a railroad car loading facility.

FERTECO MINERACAO S.A.

SEPETIBA BAY, BRAZIL

Ferteco Mineracao S.A. (“Fertico”) the then third largest producer of iron ore of
Brazil engaged Soros Associates, Inc. to undertake feasibility and later detailed
design, supervision of fabrication and erection of a Dual Linear Loader (“DLL”)
at its port terminal located at Sepetiba Bay, Brazil.
Soros was initially engaged to undertake a feasibility study in that was later
upgraded to a bankable study. Then Ferteco, after achieving compliance with
then Brazilian Port Legislation, received authorization to proceed to implement
and operate its own iron ore export terminal at Sepetiba Bay, approximately
80kms west of Rio de Janeiro. Through the feasibility study, Soros had identified
and recommended that a DLL would be the most economical loader design
with respect to meeting the project requirements of loading up to Cape Size
bulk carriers.
Ferteco formed a new subsidiary, Companhia Portuaria Baia de Sepetiba
(“CPBS”) who then engaged Soros to undertake the engineering of the DLL.
This engagement was then expanded to include supervision of fabrication
and erection of the DLL.
The principal components of a DLL are the rear and front portals, bridge,
shuttle, mast and boom. The DLL is an improved version of earlier Linear Loaders
developed by Soros during the 1970’s. The Sepetiba DLL was developed by Soros
to load up to 20Mtpa of iron ore exports into bulk carriers ranging from 30,000
to 230,000 DWT. The loader is designed with for continuous heavy-duty operation
rated at 10,000tph. The boom luffs and shuttles in and out, in order to optimize
hatch loading and minimizing free fall of product, thereby also assisting in
achieving the required load rate.
After completing a tender package based on the Basic Design of the DLL, Soros
recommended a shortlist of worldwide experienced manufacturers (incl. Brazilian
based manufacturers) and participated in the interview of the shortlisted parties.
The contract was awarded to Bardella Industrias Mecanicas S.A. located in
Guarulhos, Sao Paulo, Brazil.

    at the power plant.
    The project consisted of a 1450 TPH, 36-inch-wide, 1417-foot-long, copper
    concentrate conveyor and shiploader. The copper concentrate conveyor is
    fed by two variable speed reclaim feeders located in the copper concentrate
    building. The reclaim feeders are fed by front end loaders. The copper concentrate
    conveyor feeds the shiploader. The shiploader slews through a 285-degree arc and
    incorporates a shuttling type boom and conveyor. The shuttling boom can provide
    reach from 41 feet out to 135 feet from the shiploader pivot. The shuttling boom
    conveyor transports the copper concentrate to the ship through a telescopic loading
    spout. An operator’s cab is provided on-board the shiploader with a radio control
    unit that permits remote operation.
    The project consisted of a 440 TPH coal barge unloading and stockpiling
    system, featuring a 165-foot-long unloading conveyor with a hopper that is fed
    from a front end loader. The hopper is located on the floating dock. The coal
    barge unloading conveyor is pivoted to allow vertical movement for varying tide
    levels. The coal barge unloading conveyor feeds a 2160-foot-long coal stockpiling
    conveyor with a stacking tube located at the head end. The conveyors are
    controlled from a control panel located near the dock.

    Roberts & Schaefer Company was awarded a design and supply contract from
    LGZ Steel Partners for a direct reduced iron (DRI) material handling system in
    Port Lisas, Trinidad and Tobago for Caribbean Ispat Limited. The project included
    a conveying system that would accept iron oxide at a rate of 2800 Tons/Hr and
    transport it to a screening station where the material is sized and conveyed to a
    series of five-day bins. From the day bins, the material is conveyed to a MIDREX
    furnace and the product becomes direct reduced iron. The DRI is then conveyed
    to three gas-tight silos that feed a series of conveyors that transport the DRI to
    the melt shop or a product storage building.
    The material is stored in the product storage building by a tripper and traveling
    bridge structure that forms DRI piles within the product storage building. The
    DRI is reclaimed at a rate of 2,000 TPH through a series of slide gates and reclaim
    conveyors and sent to the dock where the material is loaded into ships by a dock
    conveyor and traveling tripper.

shiploader, Soros was then engaged to work in conjunction with Hatch Associates,
and provided the following condition assessment services that comprehended:
• Structural review of structural joint separation, deformity of the portal frame
  and traverse trucks;
• Bird nesting of the drum hoist rope;
• Boom pivot pin not working resulting in keeper plate bolt failure; and
• General overall condition assessment of the radial boom.
• After completion of the visual inspections, in non-operating mode noting
  the poor condition of the machine at the time, design detail drawings were
  developed to correct all structural problems, along with drawings to show how
  the structure was to be supported to carry out joint replacement and strengthen
  truss members. The on-site component of the work had duration of one week,
  and the reporting, procedure writing and repair programming duration was
  around one month. The documentation was furnished to Hatch Associates,
  who were then charged with completing the remedial and corrective works
  in accordance with the reports.

TOTAL ENERGY PLANT, GUAYAMA, PUERTO RICO

Engineering, procurement, construction, start-up and commissioning of the coal,
limestone and aggregate material handling systems included ship loading and
unloading; the contract was awarded by Duke/Fluor Daniel.
The coal and limestone are received in self-unloading ships. The ash is shipped
out in geared ships or ocean barges. The dock area consists of the coal/limestone
receiving hopper with belt feeder and the aggregate ship loader.
The single path series of conveyors with a length of 3,600 feet from the dock to the
material handling areas are reversing conveyors and handle all three materials.
The coal or limestone is conveyed from the 50,000-ton capacity ships at 3,000 TPH
to the storage areas and the aggregate is conveyed at 1,800 TPH from the storage
area to the 9,000-ton capacity ocean barges.
The coal handling stockout and reclaim system consists of two stacking tubes
with a total pile capacity of 98,000 tons and a series of ten variable rate vibratory
feeders located below the piles for reclaim at 720 TPH.
The limestone stockout and reclaim system consists of a conveyor from the second
coal stacking tube to the limestone stacking tube enclosed in a dome for dust and
moisture control.
The bottom and fly ash are combined from the ash silos and conveyed to the initial
storage area. This manufactured aggregate (ash product) is reclaimed by mobile
equipment to a hopper with a 1,800 TPH feeder breaker and sent to the ship loader
via the reversing conveyor system.
The shiploader is equipped with a telescopic spout and a retractable boom
conveyor. The aggregate systems include wet suppression for dust control.               All unloading, stockpiling, reclaiming,

    COAL HANDLING SYSTEM, MARLBORO, NEW YORK

    Scope: Engineering, procurement, construction, start-up and commissioning,
    The project is comprised of self-unloading vessels (30,000 ton DWT class) which
    deliver coal to the existing Roseton Dock. This tonnage is three times the amount
    now delivered by rail. The dock was modified to receive additional coal.
    The coal receiving hopper and a belt conveyor were installed on a marine cell
    in which the vessel unloads at rates up to 2,000 metric TPH. The hopper is
    enclosed to contain fugitive dust. The self-unloading vessel with coal is breasted
    against the existing dock. The unloading conveyor boom is positioned over the
    receiving hopper and inside the enclosure.
    Conveyor BC-1, located under the receiving hopper, conveys coal to Transfer
    Tower 1, then the coal transfers to Conveyor BC-2 at the rate of 2,000 MTPH.
    Conveyor BC-2 travels to Transfer Tower 2, where the coal is proportioned between
    the existing stockout (500/1,000 MTPH rating) via Conveyors B-3 and BC-4.

NEW HOPE CORPORATION LIMITED

Scoping Study for Upgrade or Replacement of Shiploader, QBH Coal Terminal,
Port of Brisbane (QLD), Australia
Soros undertook a condition inspection of the shiploader, which comprehended:
• Interviews with QBH management, operations and maintenance personnel
  using a set questionnaire;
• Review of maintenance and operating records;
• Review of maintenance access (especially to jetslinger) and related
  safety matters;
• Review of drawings (as-built through to modifications) and associated
  reports for the condition assessment and wharf capacity analysis;
• Observation of the machine both in working and static modes, along with
  recording of notes and photographs; and
• A detailed report identifying key issues associated with safety,
  environmental and operating matters.
Soros was able to establish a solid justification for the replacement of the existing
ship loader and the next phase of work required Soros to complete the scoping of
replacement design options and provide a capital cost estimate for such options
and also benchmark the estimate against other designs.
The QBH wharf is narrow by modern standards and the elevated feed
conveyor running parallel to the wharf is to remain in-situ. These constraints
in which the new shiploader design must fit mean that the replacement of the
shiploader will see a custom applied design. Soros is continuing to work with
QBH to deliver a suitably designed shiploader to meet these requirements
and the overall design criteria.

BALTIMORE GAS & ELECTRIC COMPANY

BRANDON SHORES, UNITS 1 AND 2,
ANNE ARUNDE L COUNTY, MARYLAND
Complete project management, detailed engineering, procurement and
construction services were provided under a turnkey contract. This contract
covered the major coal handling facilities serving two new 620 MW units
of the Brandon Shores Power Plant on the Patapso River.
A major feature of the coal handling facility is a system to receive coal by
7,000-ton capacity barges. This installation involved extensive marine works,
including a 3-barge dock, jetty way and a barge haul system to move the
barges during unloading.
A high capacity 4,000 TPH continuous bucket elevator barge unloader was
installed on the new jetty way. An innovative construction method was developed
for the assembly of the barge unloader. The entire machine was pre-assembled
on shore and shipped in one piece on a floating barge crane.
The barge unloader discharges to a high capacity 72" collecting conveyor.
The conveyor is in a fully enclosed ventilated gallery. Coal is conveyed over
the water and inland to a transfer station some 2,100' away (of which 1,700'
are over water).
Once the coal is delivered on shore it is sampled at a transfer station. It is
then either directed to a radial stacker (discharging to a ground storage system
serving the existing Wagner Station), or onto another conveyor serving the main
coal storage stockpile system for Units 1 and 2. This conveyor discharges to
another transfer station.
From here coal is directed to either the inactive storage pile (by a cantilevered
conveyor fitted with a telescopic chute), or the active storage pile (by the yard
belt for delivery to a stacker reclaimer). The stacker reclaimer has a 20' diameter
bucket and is fitted with a trailing tripper and stacking slewing boom.
4,400 TPH of coal handling capability.

     PORT OF LYTTELTON

     CHRISTCHURCH, NEW ZEALAND

     Soros was engaged by Opus International Consultants Ltd, NZ (“Opus”)
     to undertake an investigation into the means of achieving an increase
     in throughput from 18,000tpd to 25,000tpd and the capability to load
     larger vessels that the existing Panamax bulk carriers.
     Alternative concepts for the upgrade of the terminal were prepared and compared.
     The 30 year old shiploader was examined and upgrade measures and repair works
     were identified. The outreach and throw of the machine were investigated in order
     to facilitate loading of larger vessels, with the latter being the solution that was
     eventually implemented. Individual measures to upgrade the electrical and control
     systems of the terminal, conveyors, train unloading and reclaim system were
     identified and implemented.
     The initial study work completed by Soros looked at various options for the
     upgrade and the respective equipment. An opportunity was identified to utilize
     second hand coal handling equipment. Soros then re-engineered to construction
     level the equipment to suit its application in the Lyttelton stockyard. Soros also
     produced specifications to procure replacement/new equipment and provided the
     consulting support during the procurement, fabrication and construction phases
     of the project. Detailed shiploader modeling identified the need to add a telescopic
     chute and jet-slinger, along with increasing belt speed, adding a motorized cable
     reeling system and associated controls. Soros was also called upon to assist and
     report on a commissioning troubleshoot brief.
     In 2008 Soros and Opus agreed to jointly work together to deliver to LPC and its
     client Solid Energy New Zealand Ltd further consultancy services for the upgrade
     and expansion of the coal terminal at the Port of Lyttelton. The objective of the
     consultancy services was to identify and assess plausible options for expansion
     of the materials handling systems (“MHS”) in accordance with proposed plans
     for the overall expansion of the stockyard and any possible development staging.
     Soros provided its services through three stages of the project:
     • An ideas definition phase
     • Prefeasibility which required conceptual design and ±30% capital estimates; and
     • Feasibility which required preliminary design with ±20% capital estimates.

     The client had noticed that deterioration of the reinforced concrete structures was
     occurring in both landside (shed slab) and marine installations. CMDI retained
     Soros Associates, Arze Recine y Asociados, and Wiss, Janney, Elstner Associates
     (S.A.W.) to undertake a four phased investigation to identify the cause and make
     a recommendation as to how best to correct the ongoing problem.
     Soros’ investigation and report indicated that serious reinforcement bar corrosion
     had occurred and that the client could expect if this problem was not corrected that
     serious failure of the supporting structure would also occur.
     Further into the investigation Soros returned to site and assessed the extent
     of reinforcement bar corrosion. In some samples it was found that loss due
     to corrosion was as high as 50%. The inspection of all foundations showing
     signs of failure was undertaken, and each site of corrosion was then classified
     according to criticality and potential failure, with a scale ranging from in need
     of repair through to replacement. Soros also provided a cost estimate and

Due to a number of conditions such as surge loading, off centering loading,
impact loading, under-designed system, and the transloading operation,
a considerable loss of unrecovered product was resulting. Although there
was no execting method to accurately assess the loss, it was estimated
to be 0.5% to 1% of the yearly throughput, which amounts to a loss of
US $10M to $15M per year. In order to reduce the loss of product,
PT Freeport had decreased the handling rate from 2,000tph to 1,400tph.
At the request of PT Freeport Indonesia, Soros carried out a site investigation
of PT Freeport’s copper concentrate shiploading and reclaim system. The objective
of this site visit was to:
• Assess current cause of spillage of copper concentrate;
• Determine and recommend feasible options for
  containment and recapturing of spillage;
• Assess adequacy of the existing system;
• Provide a short term improvement plan;
• Provide a long term solution plan;
• General assessment of structural steel corrosion; and
• Provide a budget cost estimate for a new shiploader capable of loading vessels
  up to 55,000 DWT without the need to shift the vessel
Soros undertook a detailed inspection and observation of the plant, both under load

Soros was appointed to a six year term contract by Credit Lyonnais Singapore
to undertake annual inspection of the coal barging transport infrastructure.
The objective of these inspections was to carry out detailed assessment of the
transport chain to ensure reliability of the supply chain to the power plants.
The Soros program of activities included:
Retrieve background information to compare original project objectives,
last findings report results and this report findings;
Prepare an activity check list of items that need to be investigated for each
link of the coal transportation system;
Dispatch marine and material handling specialist to the site;
Meet with the onsite project manager and obtain his input as the current
situation and to determine what changes and or improvements were made;
Meet with operations and maintenance personnel at each coal handling
transfer and obtain their input;
Obtain and assess yearly operating and maintenance records for the
complete transportation link including; barge operation and river data;
Record all data and prepare a daft findings report including suggested
improvements that will reduce cost and improve the operation;
Review draft findings report with project manager and record his comment; and
Furnish a final report which outlines the findings of the assessment.
With the various elements of the transport chain being examined annually
to assure adequate coal supply to the Paiton Power Plant, aside from truck
transportation and barge transportation, particular consideration and
assessment was given to the shipping channel at the exit of the river and
the availability of the berths at the Pulau Laut Terminal. In all the reports
the coal transport was reconfirmed to be adequate and reliable for the
next 20 years.
It was learned that another company crossed the open sea to Java directly
with river barges. Therefore Soros was asked to examine that Alternative,
which eliminated the need of transhipment of coal from barges to Handymax
at the Pulau Laut Coal Terminal. The outcome of this investigation [which
included wind, waves and weather related research at the Java sea],
confirmed that direct shipment of coal in barges was a viable alternative.

     and rail unloading of dry products, and increase the export of dry products to a
     rate 5M tons per annum over a 3 to 7 year period
     Roberts & Schaefer was awarded the contract to complete the feasibility study.
     Staff from R&S and Soros visited the site to obtain preliminary information and
     discuss project objectives. Further visits were to observe the loading of two bulk
     carriers and the unloading of a sulphur barge. The scope of work required R&S
     and Soros to assess options for handling the increased freight task in each stage
     and provide design and cost estimates.
     Phase 1 of the study was to determine the best means and methods for
     allowing the import of 500,000 tons per annum of dry products by truck
     and then exporting 2.5Mtpa via Panamax or Handymax vessels from
     the facility. Phase 2 would see an increase in the export of dry products
     to 5Mtpa by receiving 2.5Mtpa of dry products by rail from Bartow
     and Green Bay plants.
     Also included in the study was a site and logistical review of existing systems
     and truck paths for the added truck traffic resulting from implementation
     of the project. With the increased traffic into the Riverview plant, a review
     of the entrance into the plant was also completed.
     The then current dock facilities, including the existing ship loader, the depth
     of the channel, and the length and depth of the berth, were not capable of
     accommodating Panamax sized vessels. The study included methods and
     means for upgrading to allowing the use of Panamax vessels (deepening dredging
     of berth pocket and turning basin while keeping the existing facility operational.
     The existing ship-loading rate was approximately 750tph and it was planned
     to remain at this rate in Phase 1. This tonnage rate was then to be increased
     to 2,000tph by way of introducing a new shiploader in Phase 2, thereby
     providing faster loading of Panamax vessels. Due to the increased volume
     of product being shipped, a review of adding an additional 150,000 tons
     of dry products storage was also completed which resulted in modifications
     to the shed and conveyor systems.

PORT LATTA OPEN SEA ORE TERMINAL TASMANIA

The project was an open sea loading berth for magnetite ore pellets at Port Latta,
in northwest Tasmania. The facility enabled the development of the magnetite
deposit at Savage River for Savage River Mines Limited.
An open cut mine, concentrator plant and township were developed at Savage
River, 100 km south west of Burnie. A pipeline was constructed from the
concentrator to a palletizing plant and dedicated port facilities at Port Latta.
Production commenced in 1966 supplying Japanese steel mills with 45 million
tons of palletized magnetite ore over a 20 year period
Soros was responsible for the feasibility study and complete detailed design
of the facility which comprises a 1.8 km approach trestle and dual radial
shiploaders for the continuous loading of ore carriers up to 125,000 DWT
at a rate of 3,500 tons per hour. The ore stockyard utilized a rail mounted
stacker and two crawler mounted bucketwheel reclaimers. An auxiliary
harbor with breakwater for tugs, lineboats and maintenance barges also
accommodated floating construction equipment.
A large crane barge was mobilized from San Francisco and towed 16,000 km
to the site. The marine structures were prefabricated steel jackets and precast
concrete caps. Initially a temporary outer jacket with spud legs was installed
and leveled. Then followed the second permanent jacket, through which rock
sockets were drilled into the bedrock for the insertion of pin piles that were
subsequently grouted.

     BUNBURY ALUMINA LOADER WESTERN AUSTRALIA

     Soros provided complete detailed design engineering for a shiploader and marine
     facilities at Bunbury, Western Australia, for Alcoa. The alumina loading facility
     includes a linear loader delivering 2,000 tons per hour of alumina to vessels up
     to 50,000 DWT. The structures comprise four berthing dolphins, unloader support
     platform and an approach bridge.
     The linear loader was invented and patented by Soros in the 1970’s to increase
     the ship coverage obtained for a given overall shiploader length, compared with
     a radial (or quadrant) loader which was also developed by Soros in the 1960s.
     The linear loader has a variable span slewing bridge supported at the front
     on a turntable that travels on a linear track parallel to the vessel. The support
     at the rear pivot allows the bridge to rotate and slide. The loader was designed
     with a high efficiency collection system for dust free operation.
     The marine structures are supported on steel tubular piles anchored to the rock
     seabed with drilled in spuds. This was the first fully enclosed bulk loading facility
     in Australia, an environmental ‘first’ at the time and the shiploader design was
     later recognized with an award reflecting this advancement.

PORT KEMBLA COAL TERMINAL PORT KEMBLA,
NEW SOUTH WALES
Soros Associates, in collaboration with Soros Longworth and McKenzie,
provided to the New South Wales Department of Public Works complete project
management services which included feasibility study, operational simulation,
detailed engineering design of all civil works and structures, bid evaluation,
assistance with construction supervision, inspection and start-up.
The Port Kembla Coal Terminal development featured dredging, seawall and
reclamation, onshore foundations, marine structures, site civil and road works,
rail car and truck dump facilities, conveyor system, stackers, reclaimers,
shiploaders, environmental services and controls and service and administration
buildings. The project commenced in 1979 and was completed in 1982.
Phase 1 of the development catered for an annual capacity of 16 million tons
for 16 grades of coal, with provision for expansion to 22 million tons in Phase 2.
An interesting note is that PKCT has performed at 18 million tons per annum
(Mtpa) (on a monthly annualized basis) in recent times. Vessels to be loaded in
Phase 1 were 120,000 DWT to full draft and 160,000 DWT to partial draft.
During March 2007, a record performance at PKCT was achieved with loading
the largest cargo uplift of 166,000 tons onboard the Sen-Oku and achieving
a displacement of 206,000.
Phase 1 provided:
• 5 km of high capacity conveyors
• train unloading within one hour
• 3 lane road over a covered slot storage enabling 9 trucks
  to unload simultaneously
• automatic washing of trucks before leaving the terminal
• multiple stackers to eliminate train unloading delays
• coal reclamation by two 6600 tph bucketwheels
• two travelling shiploaders fed by a single 6600 tph conveyor
• automatic stockpile dust suppression spray system actuated
  by inventory, wind speed and direction
• designed system redundancy allowing operation with any
  single major machine out of service
• open deck wharf minimizing cost of marine construction
SLM received an Award of Merit from the Association of Consulting Engineers
Australia for its work on the Port Kembla Coal Terminal project.
Current throughput at PKCT is 11.7 Mtpa of coal and capacity of 16-18 Mtpa.
As a result, PKCT has spare capacity of 6 million tons available, which is unique
compared with other coal terminals on the Eastern Seaboard of Australia.

     Preliminary concept designs and cost estimates for the Kooragang Coal Terminal
     at Newcastle were provided to the Maritime Services Board (“MSB”) of NSW by
     Soros Associates and its affiliate Soros Longworth & McKenzie. Later, the detailed
     engineering contract initially entered into with the MSB was assigned over to
     BHP Company Pty Ltd (“BHP”), who had been appointed as project managers.
     The project featured geotechnical investigations and pre-loading concepts,
     conceptual design and master planning of the staged development, preliminary
     engineering, cost estimates, detailed design and contract documentation for
     marine and civil works, foundations, structures, services, environmental
     controls and conveyor equipment contracts, tender documents and bid
     evaluation for shiploaders, reclaimers and stackers. Construction support
     was also provided to the project manager, BHP.
     The state of the art coal terminal was designed for an initial capacity of
     15 Mtpa with 40 different grades of coal and for expansion to 50 Mtpa with
     100 grades. Other principal design features included:
     • Unloading of trains with 3200t payload in 30 minutes at
       a rate of 7300 tph (then a record)
     • Shallow railway unloading pit used a 6,600 tph belt feeder
       3.2m wide, VVVF drive (then a record belt width)
     • Multiple 7,300 tph stackers to eliminate waiting time between
       trains with different grades
     • Coal reclaimed by 8,800 tph bucketwheel reclaimers,
       then the world’s largest
     • Shiploading system with a booster bin, fed by over 3.6 km of high
       capacity conveyors, achieved a peak shiploading rate of 12,000 tph
       into vessels ranging from 25,000 DWT to 180,000 DWT
     • Open deck wharf minimized cost of marine construction
     • Dredged pull off waiting basin enabling tidal departures,
       increasing berth availability (later covered with second
       and third stage berths and loaders)

NEWMONT MINING

TRUCK MAINTENANCE & WASH FACILITY, CARLIN, NEVADA

Roberts & Schaefer Company has worked for Newmont Gold Company for over
30 years on a variety of mining related material handling and processing projects.
When the need arose to build a new maintenance and wash facility for their large
haulage trucks at their Gold Quarry Mine near Carlin, Nevada, they looked to
R&S to help.
Newmont contracted with R&S to complete a feasibility study to determine the ex-
acting requirements for a new haul truck maintenance facility and was ultimately
awarded the turnkey contract to engineer, procure and construct the facility.
The final design included 6 repair bays and one wash bay with plans so that
additional repair bays could be added at a later date. The shop was designed to
accommodate the larger 797 haul trucks with beds full up. Crane hook clearance
was set at 52 feet. Roberts & Schaefer stepped up to the challenge of a difficult
schedule and delivered the new shop on budget, with zero lost time injuries, and
only one week behind the allotted 63-week schedule. As many as 15 separate
subcontractors at one time were managed on-site by R&S to accomplish this goal.
The 53,000 SF pre-engineered steel building truck shop included
the following features:
• Six repair bays with drive through capability
                                                                                     Roberts & Schaefer can engineer ancillary
• 18-inch thick repair bay concrete floors with centerline drain trench

    US BORAX

    TRUCK MAINTENANCE & WASH FACILITY,
    BORON, CALIFORNIA
    U.S. Borax was in critical need of a new truck shop to accommodate a fleet of
    27 new mine trucks. The trucks were purchased for both open pit mining and
    to expedite removal of overburden created when a major portion of the existing
    pit collapsed onto the ore body. Time was of the essence as Borax did not have
    a building with high enough doors and cranes or a thick enough slab to
    accommodate repair and maintenance of the new trucks.
    The scope of the project included 5 repair bays for 240 ton mine trucks, two
    30/5-ton overhead cranes, four high volume lube racks, concrete lube bay with
    six lubricant tanks, six closed offices, one supervisors office, a lunchroom,
    bathrooms and showers. The existing offices were remodeled and separation
    walls installed where required. New concrete aprons were installed and a slab
    was poured at the tire shop.
    Land was limited and Borax wanted to integrate the shop with their existing
    facility. In the final solution the new building mirrored the largest existing
    building. The existing sectional doors were removed resulting in a 10 bay shop.
    Modifications were made to the existing buildings to improve the working
    environment and to meet fire codes. The fire code issue was especially difficult
    due to the enormous size and height of the building. Numerous meetings were
    held with Kern county to resolve the fire issue.
    A new truck wash facility was built to replace the antiquated system in place.
    The new wash area is open air with 40' high concrete walls as wind protection.
    Eight water cannons can be directed from floor level and an 18' high walk way.
    High-pressure steam, hot water, and detail hoses are also available. The recycle
    pond is four stage but due to the nature of boron, settling of the sediment is
    difficult. Approximately 30% of the water is replaced automatically during use.

RO BERTS & SCHAEFER EXECUTION SUMMARY




As an Engineering, Procurement and Construction company, Roberts & Schaefer’s
execution goal is straightforward: To deliver each and every project in a quality
manner, on schedule and on budget. “Quality manner” means meeting or exceeding
all required client specifications, as well as for those items not specifically called
out by the client.
The company is structured, and our processes are established, with this execution
goal in mind. Our organization is set up to optimize efficient performance of
project tasks while maintaining management oversight. Our dedicated staff
has deep experience in our markets: bulk material handing (BMH) and material
processing solutions. All of our processes, from pre-award through construction,
are geared to achieving this goal.
The Roberts & Schaefer organization consists of Power and Mining Profit & Loss
(P&L) centers. This allows the company to align with our principle clients. We
are a “strong matrix” organization; meaning we have full-time dedicated project
management and controls while maintaining functional oversight of deliverables.

An upper level view of the Roberts & Schaefer organization follows:

    RO BERTS & SCHAEFER EXECUTION SUMMARY




    Each project is assigned a Project Manager who is responsible for all aspects
    related to the project (meeting the execution goal) and is the primary interface
    with client management. Task management, process standards and guidance
    are provided by designated functional managers. Overall management oversight
    and control is provided by senior management.
    In addition to a standard Microsoft Office software toolkit, Roberts & Schaefer
    employs the following:
    • CCAS software for accounting and cost tracking functions
    • Adept for documentation control
    • AutoCAD for Engineering design
    • Bentley for 3D Engineering design
    • Primavera Scheduling Program
    Roberts & Schaefer recognizes the critical importance of proper staffing. Each
    P&L is led by a President who is a proven, experienced EPC business leader.
    These Presidents are responsible for overall performance, operation and
    administration of the P&L. Roberts & Schaefer also uses Senior Vice Presidents
    (SVP) as process guides. SVPs are typically very experienced leaders who serve
    as mentors to help resolve issues and, most importantly, to prevent problems and
    improve project performance. Vice Presidents lead each of the key disciplines at
    Roberts & Schaefer. VPs are established for areas including:
    • Project Management
    • Engineering
    • Procurement
    • Construction
    • Estimates
    • Sales/Marketing
    These VPs provide direct guidance and oversight for their specific areas as well
    as overall process interface with the rest of the business. The VPs often serve as
    overall functions leaders for their respective areas. The functional role cuts across
    the P&Ls (Power and Mine) to help ensure maximum uniformity of process. The
    functional purpose is to consistently apply best practices across the business.
    Project Managers are the single point of contact, internal and external, responsible
    for all aspects of the projects. Roberts & Schaefer applies industry standard project
    management techniques based on Project Management Institute guidelines
    (PMBOK). Project Managers are expected to ultimately obtain PMP certification.

    RO BERTS & SCHAEFER EXECUTION SUMMARY




    Successful project execution starts with the pre-award process. This is the primary
    focus of the Sales and Estimating groups. Critical considerations in the pre-award
    process are establishment of baseline scope (division of responsibility), baseline
    schedule, proper budget and client-specific technical requirements. The Sales and
    Estimating group’s key functions are:
    • Identification of opportunities
    • Negotiations with clients
    • Preparation of budgetary estimates
    • Preparation of formal proposals
    • Interface with other Roberts & Schaefer departments
    • Brief and obtain formal approval of senior management
    Once a project is won, the Engineering process comes into play. While each
    project is unique, the general flow of engineering development is as follows:
    • Layouts: establish the overall process and general area configuration that
      will meet the needs of the project in the most efficient manner possible
    • Structural: design the structure that supports the BMH system
    • Mechanical: design the mechanical system that carries out the BMH function
    • Piping: the design the ancillary piping that is necessary for the BMH system
    • Electrical: the design the electrical system that powers and controls
      the BMH system
    Roberts & Schaefer sometime uses subcontracted engineering services as
    a variable workforce to augment our own engineering resources. Relationships
    with these engineering subcontractors have been established over the years
    and they function seamlessly with in-house engineering.
    Roberts & Schaefer recognizes the critical nature of documentation and proper
    submittals. The Engineering Services group focus is on this need.
    Engineering ties directly into procurement. The Procurement group maintains
    approved vendor and subcontractor lists. The group continuously reviews
    performance via a scorecard system to ensure that quality and delivery
    milestones are met. The group also reviews and negotiates contracts and
    purchase orders, issues the contracts, monitors progress and closes out the
    contracts/purchase orders once the task is complete.

RO BERTS & SCHAEFER EXECUTION SUMMARY




Roberts & Schaefer maintains a very experienced construction management
(CM) staff with average experience of more than 25 years. The CM group manages
mobilization of all equipment, materials and staff necessary to complete the project
implementation in the field. The mobilization effort requires interface with overall
client project management on-site to coordinate activities. Our CMs typically have
an office manager/administrative assistant to support documentation and may
have assistant CMs and/or Field Engineers as well, depending on the size and
complexity of the specific project.
The CM staff manages and coordinates each phase of construction including:
• Civil / Earthwork
• Concrete
• Steel Erection
• Electrical
• Completion of punch list items
• Startup/Testing and Commissioning
• Client training
On completion of site construction activities, the CM will coordinate demobilization
of Roberts & Schaefer-related equipment and materials.
Roberts & Schaefer is committed to being a continuous learning organization.
At the project level, an extensive lessons learned database is maintained.
Procurement evaluation scorecards are maintained and evaluated to ensure
best possible performance from vendors and subcontractors. Roberts & Schaefer
also does benchmarking and seeks innovative industry best practices to improve
performance and efficiency.
Roberts & Schaefer believes its most valuable asset is our staff who are
committed to maintaining and improving performance. PMs are expected
to ultimately achieve and maintain PMP certification status; engineers obtain
and maintain PE licenses. Staff attend classes and perform self-study to improve
business-related knowledge and skills. Roberts & Schaefer has implemented
a goal-oriented performance review and appraisal process to ensure personnel
development aligns with the needs of the business.
Serving the needs of clients by delivery of high quality products and services,
on schedule and on budget reflects the heritage and reputation of Roberts &
Schaefer—a reputation that is precious to us as we continually seek ways to
uphold and improve it.
