ODOT Aspirational Diversity Targets - While Aspirational Diversity Targets are not
requirements for this contract and are not binding on the contractor, ODOT desires to
encourage the highest possible participation of minorities and women in the work force.
Therefore, ODOT has established aspirational targets on OTIA III contracts statewide and
all ODOT construction contracts in Multnomah, Clackamas, and Washington counties as
follows:

                                         Covered Areas

                         Area                                 Aspirational

               ODOT Region 1                           Women 14% - Minority 20%
            ODOT Region 2, 3, 4, & 5                   Women 14% - Minority 14%

Neither Contractor nor its subcontractors are under any obligation to meet any aspirational
targets.

BY THE FACT, IF IT IS A FACT, THAT THE DESTRUCTION, DAMAGE, DEATH, OR
INJURY WAS OCCASIONED BY OR CONTRIBUTED TO BY THE NEGLIGENCE OF
RAILWAY, ITS AGENTS, SERVANTS, EMPLOYEES OR OTHERWISE, EXCEPT TO THE
EXTENT THAT SUCH CLAIMS ARE PROXIMATELY CAUSED BY THE SOLE
NEGLIGENCE OR SOLE WILFUL MISCONDUCT OF RAILWAY.

THE INDEMNIFICATION OBLIGATION ASSUMED BY CONTRACTOR SHALL INCLUDE
ANY CLAIMS, SUITS OR JUDGMENTS BROUGHT AGAINST RAILWAY UNDER THE
FEDERAL EMPLOYEE'S LIABILITY ACT, INCLUDING CLAIMS FOR STRICT LIABILITY
UNDER THE SAFETY APPLIANCE ACT OR THE BOILER INSPECTION ACT,
WHENEVER SO CLAIMED.

Contractor further agrees, at its expense, in the name and on behalf of Railway, that it shall
adjust and settle all claims made against Railway, and shall, at Railway's discretion, appear
and defend any suits or actions of law or in equity brought against Railway on any claim or
cause of action arising or growing out of or in any manner connected with any liability
assumed by Contractor under this Agreement for which Railway is liable or is alleged to be
liable. Railway shall give notice to Contractor, in writing, of the receipt or dependency of
such claims and thereupon Contractor shall proceed to adjust and handle to a conclusion
such claims, and in the event of a suit being brought against Railway, Railway may forward
summons and complaint or other process in connection therewith to Contractor, and
Contractor, at Railway's discretion, shall defend, adjust, or settle such suits and protect,
indemnify, and save harmless Railway from and against all damages, judgments, decrees,

Railroad Protective Liability coverage the certificate must specifically state that Portland &
Western Railroad IS AN ADDITIONAL INSURED.

Any coverage afforded Railway, the Certificate Holder, as an Additional Insured shall apply
as primary and not excess to any coverage issued in the name of Railway.

Such insurance shall be approved by the Railway before any work is performed on
Railway's Property and shall be carried until all work required to be performed on or
adjacent to Railway's Property under the terms of the Contract is satisfactorily completed as
determined by ODOT, and thereafter until all tools, equipment and materials not belonging
to the Railway, have been removed from Railway's Property and Railway Property is left in
a clean and presentable condition. The insurance herein required shall be obtained by the

(Exhibit C & C-1)
The Railway File reference number and ODOT Project information shown at the top of this
Agreement, must appear on any original insurance policies or certificates of insurance sent
to Railway by the Contractor.


Section 3 - The Contractor will observe and comply with all the provisions, obligations and
limitations to be observed by Contractor which are contained in the CONTRACTOR
REQUIREMENTS (Exhibit C), and shall include, but not be limited to, payment of all costs
incurred for any damages to Railway roadbed, tracks, and/or appurtenances thereto,
resulting from use, occupancy, or presence of its employees, representatives, or agents or
subcontractors on or about the construction site.

Section 4 - Contractor shall be responsible to Railway, including its affiliated railway
companies, and its tenants for all damages for any unscheduled delay to a freight or
passenger train that affects Railway's ability to fully utilize its equipment and to meet
customer service and Contract obligations. Contractor will be billed, as further provided
below, for the economic losses arising from loss of use of equipment and train service
employees contractual loss of incentive pay and bonuses, and contractual penalties
resulting from train delays, whether caused by Contractor, or subcontractors, or by the
Railway performing Railway Work as required by the project. Railway agrees that it will not
perform any act to unnecessarily cause train delay.

For loss of use, Contractor will be billed per freight train hour at an average rate of
($385.33 in 1997) with annual adjustments per hour per train as determined from Railway's
record. Any disruption to train traffic may cause delays to multiple trains at the same time
for the same period.

In addition to the above damages, passenger, U.S. mail trains and certain other grain,
intermodal, coal and freight trains operate under incentive/penalty contracts between
Railway and its customer. Under these arrangements, if Railway does not meet its contract
service commitment, Railway may suffer loss of performance or incentive pay or be subject
to a penalty payment. Contractor shall be responsible for any train performance and
incentive penalties or other contractual economic losses actually incurred by Railway which
are attributable to a train delay caused by Contractor, or subcontractors.

As example, a train arrives 30 minutes after its contract service commitments and Railway
is assessed damages per terms of the contract. Either Contractor, and/or subcontractors,
caused a 29 minute delay to the train and therefore are not responsible for any train
performance and incentive penalties or other contractual economic losses actually incurred
by Railway.

As example, a train arrives 30 minutes after its contract service commitments and Railway
is assessed damages per terms of the contract. Either Contractor, and/or subcontractors,
caused a 31 minute delay to the train and therefore are 100% responsible for any train
performance and incentive penalties or other contractual economic losses actually incurred
by Railway.

The contractual relationship between Railway and its customers is proprietary and
confidential. In the event of a train delay covered by this Agreement, Railway will share
information relevant to any train delay to the maximum extent consistent with Railway

(Exhibit C & C-1)
confidentiality obligations. Damages for train delay for certain trains could be as high as
$50,000.00 per incident.

                                    SECTION 00195 - PAYMENT

Comply with Section 00195 of the Standard Specifications modified as follows:

Add the following subsection:

00195.11 Fuel Cost Price Escalation/De-escalation - A fuel escalation/de-escalation
clause will be in effect during the life of the Contract.

The Agency reserves all of its rights under the Contract, including, but not limited to, its
rights for suspension of the Work under 00180.70 and its rights for termination of the
Contract under 00180.90, and this escalation/de-escalation provision shall not limit those
rights.

   (a) Monthly Fuel Price (MFP) - A Monthly Fuel Price (MFP) will be established by the
   Agency each month. For the actual MFP, go to the Agency website at:

               http://www.oregon.gov/ODOT/HWY/ESTIMATING/asphalt_fuel.shtml

   The MFP for a given month will be the average weekly price obtained from the OPIS
   weekly listing dated the first Monday of that month for No. 2 diesel fuel for Portland,
   Oregon. Prices are based solely on rack and resellers' prices exclusive of freight, taxes,
   and special discounts. If the average weekly price is not posted by OPIS or is otherwise


SPS_13976, US30: Havlik Drive Int./Havlik Dr. Extension Section, Final with Addenda, June 23, 2009
                                                                                                     10
US30 Havlik Drive Int./Havlik Dr. Extension Sec.
Grading, Drainage, Paving, Signing, Illumination, Signals, Water line

   not available to the Agency for the first Monday of any month for any reason, the Agency
   may use the average weekly price posted by OPIS immediately before or after the first
   Monday of that month. If the average weekly prices cease to be available from OPIS for
   any reason, the Agency in its discretion will select and begin using a substitute price
   source or index to establish the MFP each month. The Agency does not guarantee that
   fuel will be available at the MFP.

   (b) Base Fuel Price (Base) - The Base fuel price for this Project is the MFP published
   on the Agency website for the month immediately preceding the bid opening date.

   (c) Monthly Fuel Adjustment Factor - A Monthly Fuel Adjustment Factor will be
   determined each month as follows:

      • If the MFP is within ± 25% of the Base, there will be no adjustment.

      • If the MFP is more than 125% of the Base, then:

              Adjustment Factor = (MFP) - (1.25 x Base)

      • If the MFP is less than 75% of the Base, then:

              Adjustment Factor = (MFP) - (0.75 x Base)

   (d) Fuel Price Adjustment - A fuel price adjustment for fluctuations in the cost of fuel
   will apply only to the major fuel usage Pay Items shown in the following list and at the
   respective fuel factors listed:

                     Item                                                       Fuel Factor

       Surcharge Excavation                                                 0.29 Gal/yd3
       Embankment in Place.                                                 0.29 Gal/yd3

       Concrete Pavement                                                    1.00 Gal/ton

   The Contractor is cautioned to consider that its operations may require more or less fuel.

   A price adjustment () to the Contractor for fuel cost changes will be made monthly if the
   Monthly Fuel Price differs 25% or more from the Base Fuel Price. This adjustment will
   be the product of the Monthly Fuel Adjustment Factor and the estimated Monthly Fuel
   Used. The Monthly Fuel Used will be determined by multiplying the quantities of Work
   accomplished during the month for subject Pay Items, by the appropriate Fuel Factors.

   Fuel requirements for constructing the Project have been estimated at 32,285 gallons,
   based on fuel factors shown.

   If the Contractor elects to use an alternate fuel (natural gas, wood pellets, propane, or
   other), the estimated fuel requirements will not be revised. Fuel cost adjustments will
   continue to be made as specified and will not be revised.

Section 00305, which is not a Standard Specification, is included for this Project by Special
Provision.

                                              Description

00305.00 Scope - This work consists of all surveying activities necessary to control the
many phases of work required to construct the Project to the lines and grades as shown,
specified, or established.

Make all supporting computations and field notes required for control of the work and as
necessary to establish the exact position, orientation, and elevation of the work from control
stations, including furnishing and setting construction stakes and marks, reference marks,
and additional control stations.

Plans, specifications and other data necessary to lay out the work will be available for
inspection at the Project Manager’s office.

00305.01 Definitions:

Confidence Points - Random points measured in the field within the boundary of a digital
terrain model (DTM), the purposes of which are to verify the accuracy of the DTM and to
provide evidence just prior to construction that the DTM is a reasonable representation of
the original ground for computation of volumes and pay quantities. Similarly, confidence
points are used to verify that a constructed grade has been built according to the design
DTM. Additional information is available from the Engineer.

Confidence point locations follow these guidelines:

   •   Randomly selected without regard for the location of DTM points or triangles
   •   Evenly distributed over the entire DTM area to be validated
   •   Proportionately distributed between confidence point classifications as applicable
   •   At a density sufficient to validate the surface, generally ten per instrument location as
       used in collecting DTM data or if not applicable, as in data collected
       photogrammetrically, 2% of DTM points

Control Network - An array of control stations either established by the Contractor or
provided by the Agency.

Control Station - Any item identified in the Project records as having a position and/or
elevation on the Project datum and intended to be used to control the many phases of the
construction work.


Digital Terrain Model (DTM) - An electronic computer model of the shape of the ground.

Reference Stakes - Stakes set away from but with information relating back to the intended
location and/or grade.

Slope Catch - The location where a design slope intersects the existing ground and where
excavation or embankment work should begin to provide the intended earthwork.

Slope Staking - The process of using measurements and calculations in the field to
determine the slope catch. Slope staking shall normally include setting stakes to mark the
slope catch and setting a reference stake for every catch stake.

Stakes - Stakes, nails, marks, string lines, or other devices or mechanisms set or
established for the purpose of indicating or controlling the location, orientation, or grade of
any feature intended for construction, or for the purpose of limiting or influencing the
construction work.

Staking - The act of placing stakes.

Survey Marker - Any survey monument, control station, or stake.

Survey Monument - Any natural or man-made item specified or identified in a property
deed, boundary survey, government document, or other instrument of public record, when
the purpose of said item is to mark or reference a property boundary, geographical location,
elevation, or other position.

surveyor, survey crew leader, and all surveying personnel who are to be involved in the
survey work shall meet with the Project Manager two weeks prior to beginning survey work.
The purpose of this meeting will be to discuss methods and practices of accomplishing
required survey work.

00305.03 Review by the Engineer - The Engineer may periodically review the notes,
calculations and layout work, including field locations, for compliance with these
specifications. Survey work that does not meet the tolerances in 00305.40 may be
rejected, and the work redone at the Contractors expense to meet the tolerances.

Review by the Engineer does not constitute approval or acceptance of the work, nor does it
relieve the Contractor of responsibility for performing work in conformance with the plans
and specifications.

Miscellaneous items not listed above will have a horizontal and vertical tolerance of
0.20 foot, unless otherwise directed. Features that are to be constructed flush to another
surface should take on the same tolerance as that surface.

Tolerances for special circumstances will be discussed at the pre-survey meeting.

00305.41 Slope Stakes and References - Set slope stakes and references on both sides
of centerline at 50 foot stations and at terrain breaks and changes in the typical section.
Establish slope stakes in the field as the actual point of intersection of the design roadway
slope with the existing ground line. Direct staking of the theoretical (computer generated)
slope stake catch point requires prior approval of the Engineer.

Set slope stake references farther out from centerline than the actual catch point. Include
all reference point and slope stake information on the reference stakes.

If an automated slope staking routine is intended to be used, the system shall be able to
perform the proper superelevation, lane transitions, and benching, as well as duplicate
other details in the design surface. The system shall record field modifications made to the
final catch slopes. Any modifications shall be recorded and provided to the Engineer.

Record the actual as staked (three dimensional) position of the slope and reference stakes.
Prepare field notes showing slope stake and reference information, and provide to the
Engineer.

00305.42 Clearing Limits - Set clearing limit stakes according to Section 00320. Space
clearing limit stakes at intervals not greater than 50 feet or as directed.

00305.43 Grade Stakes - Set grade stakes or other control for grade elevation and
horizontal alignment. Set grade stakes at each grade break line. Set additional points at
intervals, as necessary, not to exceed the width of the grading equipment, or as approved
by the Engineer. Set these rows at 50 foot stations or as required in special situations, as
in road connections and other areas where conditions require tighter spacing of grade
stakes to assure grade and alignment.

Measure and record confidence points upon completion of each course and prior to the
placement of the next course. Location and spacing of these confidence points shall be
such that they provide a reasonable record of the grade as constructed and placed at a
nominal rate of one confidence point for every 2,000 square feet of grade.

Provide confidence point data in the form of an ASCII Coordinate File Format to the
Engineer for analysis. The Engineer may request additional confidence points if quantity,
distribution, or placement does not meet the stated criteria in this subsection and in the

confidence point location guidelines in 00305.01. The Engineer may choose to collect
additional confidence points using Agency personnel.

The Engineer will evaluate the grade using any combination of industry-standard
techniques and the standard Agency confidence point analysis procedure. The confidence
point analysis will use the tolerance value defined in 00305.40 for the particular course, and
will be deemed unacceptable if less than two-thirds of all confidence points meet the
tolerance or if any confidence points exceed the tolerance by a factor of three or more.

The Engineer will evaluate the grade and provide acceptance or rejection before the end of
the first business day following receipt of the confidence point data. Do not begin
placement of the next course until the Engineer has accepted the grade and approval is
given to proceed.

00305.45 Pipes and Culverts - Stake pipes and culverts to fit field conditions.                      Their
location may be different from the plans. Perform the following:

   • Determine the roadbed slope catch points at the inlet and outlet of pipes and culverts.
   • Set reference point offsets to pipes and culverts. Record information necessary to
     determine structure length and end treatments.
   • Stake ditches or grade to make pipes and culverts functional.
   • Complete a Culvert Data Sheet (Form 734-3247) according to Agency standards.
   • Submit a copy of the field notes to the Engineer by the next working day following
     completion of the staking work.


00305.47 Manholes and Inlets - Determine the location of manholes, inlets, siphon boxes,
slope protectors, and other similar structures. This may require an approved field
adjustment to the planned location in order to avoid obstacles or assure placement at the
low point. Determine the elevation of the center of the grate.

Set a stake referencing the center of the structure. Set a guard stake with the following
information written on it:

   •   Type of structure
   •   Centerline station
   •   Centerline offset
   •   Reference distance
   •   Cut or fill to top of structure
   •   Center of structure elevation

Establish a reference line to control the alignment of the structure. Record data on the
Culvert Data Sheet (Form 734-3247) containing staking information for the outlet pipe from
the specific drainage structure.

00305.49 Horizontal Control - Establish horizontal control stations using Theodolite/EDM
network or static GPS techniques. Least squares adjustments shall be applied to either
method. The use of traverses will be permitted only if approved by the Engineer.

Preserve all Agency provided and Contractor established horizontal control stations for the
life of the Project. If the horizontal control network cannot be preserved in its original

00406.49 Railroad Crossings – Replace the paragraph beginning “Perform all work. . . “
with the following:

The contractor shall obtain all permits for work within the Railroad right-of-way prior to
beginning that work. Work shall be done according to the following standards:

   (a) General
      i.      All underground utility crossings of the railroad trackage shall be designed to
             carry Cooper’s E-80 Railroad live loading with diesel impact (AREMA Cooper’s
             loading Section 8-2-8). This 80,000-lb axle load may be distributed laterally a
             distance of three (3) feet, plus a distance equal to the depth from structural grade
             line to base of rail, on each side of centerline of single tracks, or centerline of
             outer track where multiple track are to be crossed. In no case shall railroad
             loading design extend less than ten (10) feet laterally from centerline of track.
             Longitudinally, the load may be distributed between the five-foot axle spacing of
             the Cooper configuration. Railroad loading criteria will also apply where future
             tracks are contemplated; to the extent this information is available.
     ii. All utility crossings under railroad trackage should have a minimum depth of cover
             of three (3) feet below the ground surface and five and one half (5 ½) feet from
             the base of rail. The depth of cover shall not be less than that meeting applicable
             industry standards.
   (b) General Design and Construction Requirements
         (1) If the minimum depth is not attainable because of existing utilities, water table
              ordinances, or similar reasons, the line shall be rerouted.
         (2) Underground installations may be made by open-trenching from the property line
              to the toe of the fill slope in fill sections and to the toe of the shoulder slope in cut
              sections but no closer than thirty (30) feet of the centerline of the track. The
              remainder will be tunneled, augured, jacked or directional-bored through the
              roadbed. Refer to the following sections for required encasement of utilities and
              boring requirements.
         (3) Manholes should be located outside of railroad property, when possible. No
              manhole will be located in the shoulder, shoulder slope, ditch or backslope, or
              within twenty five (25) feet of the centerline of the track, and shall not protrude
              above the surrounding ground with approval of the Railroad.
         (4) Utilities will not be attached to or routed through drainage structures or cattle
              passes. Utilities are not to be attached to other railroad structures without written
              approval of the Railroad Structures Department.
         (5) Jacking pits shall be located a minimum of thirty (30) feet from the centerline of
              the track.
   (c) Pipeline Requirements
         (1) Pipeline designs are to specify the type and class of material, maximum working
              pressures and test and design pressure. Pipelines which are not constructed,

           operated and maintained under regulations under US Department of
           Transportation Hazardous Materials Regulations Board, shall upon revisions in
           the class of material or an increase in the maximum operating pressure, must
           obtain Railroad Engineering approval.
       (2) Pipelines under railroad tracks and across railroad property shall be encased in a
           larger pipe or conduit called “casings.” Generally, casings shall extend from right-
           of-way line to right-of-way line, unless otherwise approved.
       (3) Pipelines and casing pipes shall be suitably insulated from underground conduits
           carrying electric wires on railroad property.
       (4) Reinforced concrete pipe will need to be encased for a distance as wide as the
           embankment at the utility crossing. This is to protect again track failure due to
           joint separation.
   (d) Encasement of Utilities
       (1) Casings are oversized load-bearing conduits or ducts through which a utility is
           inserted:
                  a. To protect the railroad from damages and to provide for repair, removal
                      and replacement of the utility without interference to railway traffic.
                  b. To protect the carrier pipe from external loads or shocks, either during
                      or after construction.
                  c. To convey leaking fluids or gases away from the area directly beneath
                      the railroad trackage to a point of venting at the railroad property line.
        (2) Pipelines and casing pipe shall be suitably insulated from underground conduits
            carrying electrical wired on railroad property.
        (3) Casing pipe and joints shall be made of metal, and of leakproof construction.
            Casings shall be capable of withstanding the railroad loadings and other loads
            superimposed upon them.
        (4) Wall thickness designations for steel casing pipe for E-80 loading (including
            impact) are:

                   Diameter of Casing         Min. Thickness for Coated (Inches)
                         Pipe

                    Note: this chart is only for smooth steel casing pipes with
                              minimum yield strength of 35,000 psi.

                   a. Steel pipe shall have minimum yield strength of 35,000 pounds per
                      square inch.
                   b. All metallic casing pipes are to be designed for effective corrosive
                      control, long service life and relatively free from routine servicing and
                      maintenance. Corrosion control measures must include cathodic
                      protection.

                 c. Cast iron may be used for casing. It shall conform to ANSI A21. The
                     pipe shall be connected with mechanical-type joints. Plain-end pipe
                     shall be connected with compression-type couplings. The strength of
                     the cast iron pipe to sustain external loads shall be computed in
                     accordance with the most current ANSI A21.1 “Manual for Computation
                     of Strength and Thickness of Cast Iron Pipe.”
        (5) The inside diameter of the casing pipe shall be such that the carrier pipe can be
            removed without disturbing the casing. All joints or couplings, insulators or
            centering devices shall be considered in the selection of the casing diameter.
        (6) For flexible casing pipe, a minimum deflection clearance of the casing pipe shall
            be three percent (3%) of its diameter plus one-half (1/2) inch so that no loads
            from the roadbed, track, railroad traffic or casing pipe are transmitted to the
            carrier pipe. When insulators are used on the carrier pipe, the relationship of
            the casing size to the size of the carrier pipe is:

                            Diameter of Carrier Pipe           Inside Dia. Of Casing Pipe
                                                                 Equals Outside Dia, of
                                                                    Carrier Pipe Plus
                                      0” – 8”                               2”
                                     10” – 16”                            3-¼“
                                     Over 16”                             4-½“

   (e) Casing and Pipeline Installation
        (1) Casing and pipeline installations should be accomplished by directional boring,
            jack-and-bore, tunneling or other approved methods. Tunneling construction
            under tracks will be permitted only under direct supervision of Railroad
            Engineer. Tunneling procedures and equipment, as well as structural design,
            must have Railroad Structures Department approval prior to starting any work
            on Railroad property. Generally, tunneling shall not be considered where less
            than six (6) feet of cover exists, or where excessively sandy, loose or rocky
            soils are anticipated.

              Rail elevations over the work must be monitored at intervals described by the
              Railroad to detect any track movement. Movements over one-quarter (1/4) inch
              vertically shall be immediately reported to the Railroad Roadmaster. Due to
              danger to rail traffic that is caused by on small amounts of track movement,
              Railroad forces may have to be called to surface the track several times.

              The following requirements shall apply to these construction methods:
                  a. The use of water under pressure jetting or puddling will not be
                      permitted to facilitate boring, pushing or jacking operations. Some
                      boring may require water to lubricate cutter and pipe, and under such
                      conditions, is considered dry boring.
                  b. Where unstable soil conditions exist, boring or tunneling operations
                      shall be conducted in such a manner as not to be detrimental to the
                      railroad being crossed.
                  c. If excessive voids or too large a bored hole is produced during casing
                      or pipeline installations, or if it is necessary to abandon a bored or
                      tunneled hole, prompt remedial action should be taken by the Utility
                      Owner.
                  d. All voids or abandoned holes caused by boring or jacking are to be

                    filled by pressure grouting. The grout material should be sand cement
                    slurry with a minimum of two (2) sacks of cement per cubic yard and a
                    minimum of water to assure satisfactory placement.
                e. The hole diameter resulting from bored or tunneled installations shall
                    not exceed the outside diameter of the utility pipe, cable or casing
                    (including coating) by more than one and one-half (1 ½) inches for
                    pipes with an inside diameter of twelve (12) inches or less, or two (2)
                    inches on pipe with an inside diameter greater than twelve (12) inches.
                f. Pits for boring, tunneling or jacking will not be permitted within thirty
                    (30) feet of the centerline of track; or closer to the track that the toe of
                    fill slopes in fill sections, or toe of shoulder slopes in ditch sections
                    when pipes are allowed
        (2) Vents. In casing pipe installations, vents are appurtenances by which fluids or
            gases between carrier and casing may be inspected, sampled, exhausted or
            evacuated.
                a. Vents shall be located at the high end of short casings and at both ends
                    of casing longer than one hundred fifty (150) feet.
                b. Vent standpipes shall be located and constructed so as not to interfere
                    with maintenance of the railroad or to be concealed by vegetation.
                    Where possible, they shall be marked and located at the property line.
                    The markers shall give the name and address of the owner, and a
                    phone number to contact in case of emergency.
                c. Casing pipe, when sealed, shall be properly vented. Vent pipes shall be
                    of sufficient diameter, but no less thank two (2) inches in diameter and
                    shall be attached near each end of casing, projecting through ground
                    surface at property lines.
                d. Vent pipes shall extend not less than four (4) feet above ground
                    surface. Top of vent pipes shall be fitted with a down-turned elbow,
                    properly screened; or a relief valve.
        (3) Shut-Off Valves
                a. The Utility Owner shall install accessible emergency shut-off valves
                    within effective distances on each side of the railroad. Where pipelines
                    are provided with automatic control stations, no additional valves will be
                    required.
                b. Locating a shut-off valve on railroad property should be avoided. If
                    approval is acquired, a guardrail must protect the shut-off valve.
                c. When a guardrail is required, its height shall be four (4) feet above the
                    ground line. All four corner posts shall be driven to a minimum depth of
                    four (4) feet below ground line. There shall be a minimum clearance of
                    two (2) feet from the valve to the guardrail. The steel pipes for the four
                    corner posts and guardrail shall have a minimum diameter of four (4)
                    inches. All joints will be welded with a one-quarter (1/4) inch fillet weld
                    all around.

       corrective action if the MDV test results show that two consecutive running average of
       four samples are outside the above limits for air voids, VMA, VFA, or P No. 200/Pbe
       ratio. Document the corrective action and notify the Engineer. If test results continue
       to be outside the tolerance, stop production and make adjustments. Restart
       production only after the Engineer has approved the proposed adjustments. If the
       MDV test results are outside tolerance, but the mixture meets the current
       requirements for gradation and asphalt content, an adjustment to the JMF targets is
       required. Do not start a new lot as a result of the adjustment.

       A request for an adjustment to the JMF targets may be made to the Engineer by the
       Contractor’s CAT-II. The requested change will be reviewed and documented by the
       Engineer. If acceptable, a revised JMF will be allowed. Clearly document the sublot
       test for which the adjusted targets are in effect. Adjustments for gradation shall not
       exceed the tolerances specified for the original JMF limits. Adjustments for AC
       content shall be within 0.5% of the original JMF. The JMF asphalt content may only
       be reduced if the production VMA meets or exceeds the above requirements.
       Adjustments for RAP content shall be within 5% of the original JMF, but shall not
       exceed the requirements of 00745.03. Regardless of these tolerances, the adjusted
       JMF shall be within the mixture specification control points of 00745.12. If a redesign
       of the mixture becomes necessary, submit a new JMF according to the requirements
       of these specifications.

       Perform a Tensile Strength Ratio (TSR) test (AASHTO T 283) on a sample obtained
       during the first two days of production after QC test results verify that HMAC
       constituents with a weighting factor greater than one according to 00745.95 are in
       tolerance. Provide test results to the Engineer within four working days of obtaining
       the sample. Stop production and make adjustments if the TSR is less than 70.
       Restart production only after the Engineer has approved the proposed adjustments.

       b. Laboratory Compactor Selection - Use a Gyratory compactor for MDV when a
       Gyratory compactor is used to develop the JMF. For all other cases, use a Gyratory
       compactor or Marshall compactor, as selected by the Contractor.

       c. MDV Requirements at Start-Up - Perform MDV testing at the start-up of the JMF
       production according to the following process:

          1. Obtain a sample during the first 100 tons of production and immediately
             perform MDV testing.

          2. If air voids and VMA are within tolerance, then continue remaining MDV testing
             at the established random QC sublot interval. If not, then go to step "3".

          3. If air voids and/or VMA are out of tolerance according to 00745.16(b-1-a), then
             make adjustments and immediately obtain another sample and perform MDV
             testing. Go to step "4".

          4. If air voids and VMA from the MDV testing in step "3" are within tolerance, then
             continue remaining MDV testing at the established random QC sublot interval.
             If not, go to step "5".

          5. If air voids from step "3" are more than  1.5% from the target, then stop
             production immediately and make adjustments. If they are not, then go to
             step "6". Obtain approval of the Engineer before restarting production. Begin
             MDV testing again at step "1".

          6. If air voids from step "3" are out of tolerance and 1.5% or less from the target,
             or the VMA from step "3" is out of tolerance, then make adjustments and
             immediately obtain another sample and perform MDV testing. Go to step "4".

      The initial MDV sample shall be used as the first random QC sublot test. Subsequent
      MDV samples required due to failure of start-up criteria will be used for a sublot QC
      test if the sample is taken within 100 tons of the scheduled random QC sample
      location. If not, the MDV testing shall be performed separate from, and not included
      in, the random QC testing program. Any required MDV testing will be completed at
      the Contractor’s expense.

Add the following subsection:

00745.16(b-3) MDV for Open Graded HMAC - Adjust asphalt content and gradation
targets for open graded HMAC during production as directed. The Engineer will document
the sublot test for which the adjusted targets are in effect.

00745.40 Season and Temperature Limitations In the table, for Surface Temperature of
Dense Graded Mixes 2 inches to 2 1/2 inches, replace "50 °F" with 40 °F".

00745.46 Control of Line and Grade - Add the following paragraphs to the end of this
subsection:

(The Engineer will) Establish references at reasonable intervals for line and grade control
of placement operations for the following:

   • Before placing each leveling lift.
   • Before placing the top base course for new construction.

Line and grade for the top base course of new construction and top leveling lift shall be
within 1/2 inch of design line and grade.


00745.49(b-1) General - In the paragraph that begins "Compliance with the density...",

Use the MAMD method of compaction measurement.

Replace the paragraph that begins "For Level 3 and Level 4..." with the following two
paragraphs:

For Level 2, Level 3, and Level 4 mixes, construct a control strip at the beginning of work on
each JMF on the project according to ODOT TM 306. The purpose of the control strip is to
determine the maximum density that can be achieved for the JMF, paving conditions, and
equipment on the project. Additional control strips are necessary when there is a change in
compaction equipment or when JMF targets are adjusted according to 00745.16(b-1-a).
The Engineer may waive the control strip for irregular areas or areas too small to establish
a reasonable roller pattern.

Stop paving if three consecutive control strips fail to achieve the specified density. Take all
actions necessary to resolve compaction problems. Do not resume paving until allowed by
the Engineer.

00745.49(b-3) Moving Average Maximum Density (MAMD) Method - Replace the
MAMD list with the following list:

00745.49(b-4) Control Strip Method - Delete this subsection.

00745.49(b-5) Test Results - Renumber this subsection to b-4.

00745.70 Pavement Smoothness - Replace this subsection with the following subsection:

00745.70 Pavement Smoothness - Construct the pavement wearing surface of travel
lanes to a profile that does not deviate from longitudinal and transverse smoothness more
than the specified limits of 00745.73.

Perform smoothness testing under the supervision of the Engineer with equipment
furnished and operated by the Contractor at the Contractor’s expense. Complete all
required smoothness testing no later than seven calendar days following final completion of
all travel lane paving on the Project. The Contractor accepts the risk that the smoothness
may be affected by exposure to traffic between the date the travel lanes are paved and the
date the smoothness testing is completed. If the Contractor elects to perform smoothness
measurements on a day other than the day the pavement is placed, additional traffic control
required for smoothness measurement, and not required for other work, will be at the
Contractor's expense.
