2. Project Description, Jessica Dresang and Matthew Militello, Malcolm Pirnie, Inc.
• In General, this project focuses on improvements of the effluent pumping, storage,
distribution, and disposal at the City of Goodyear (City) 157th Avenue Water
Reclamation Facility (WRF) and may be broken into two major components, the Work to
IFB-OP 10-1440 Page 1 of 4
construct the Reclaimed Reservoir and Booster Facility and all support facilities, and the
24” Reuse Effluent Pipeline and Outfall at the Gila River.
o Note that reference to ‘Reuse Effluent’ throughout the Project refers to all effluent
flow discharged from the 157th Avenue WRF, not only water being returned to the
facility for use or being reused in the City’s distribution system.
• Reclaimed Reservoir and Booster Facility and Support Facilities:
o Existing Process: Effluent from the Tertiary Filtration Facility flows by gravity to
the Reuse Effluent Pump Station. From here, this pump station conveys water to
the City’s Reclaimed Water Distribution System, back to the 157th Avenue WRF
for service water, and to the APS 96” Palo Verde Pipeline. Should the APS
Pipeline be out of service, flow may alternatively be conveyed to the Buckeye
Water Conservation and Drainage District Canal located immediately south of the
157th Avenue WRF.
o Process at Completion of the Project: Effluent from the Tertiary Filtration
Facility flows by gravity to the Reuse Effluent Pump Station. The Reuse Effluent
Pumps will convey all flow to a 1,000,000 gallon Reservoir. From there, a Reuse
Booster Pump Station will provide water to the City’s Reclaimed Water
Distribution System, the 157th Avenue WRF for service water, and should the
reservoir be sufficiently full, all effluent from the WRF in excess of demand will
be disposed of at in the Gila River. The 157th Avenue WRF will also still
maintain its agreement with APS to dispose of water to the 96” Palo Verde
Pipeline.
o Major Components and Work within the Reclaimed Reservoir and Booster
Facility and Support Facilities:
Reuse Effluent Pump Station:
• Replacement of existing Reuse Effluent Pumps, discharge piping
system, and supporting electrical and instrumentation equipment.
• Remove all debris existing in the wet well.
Sodium Bisulfite Facility:
• New chemical storage and feed facility using new equipment as
well as equipment relocated from the existing facility.
• New dechlorination dosage location for water disposed in Gila
River.
• New chlorine residual analyzer located at the south east corner of
the 157th Ave WRF.
Sodium Hypochlorite Facility:
• Minor improvements to accommodate new chlorination dosage
locations.
New Reclaimed Reservoir and Booster Facility
• Located immediately west of existing perimeter of the 157th
Avenue WRF on City of Goodyear property.
• Site grading and site security to manage stormwater and tank
overflow, as well as protect the facility.
• 1,000,000 Gallon Semi-Buried Concrete Reservoir
o Contract Documents provide designs for pre-cast
rectangular and circular AWWA D110 Type III concrete
IFB-OP 10-1440 Page 2 of 4
tank options. Contractor to submit bid with the option
selected that provides for the lowest total bid amount.
• Reuse Booster Pump Station
o High pressure constant speed horizontal split case pump
station with pumps of two different sizes.
• Supporting Electrical Facilities
o Reclaimed Reservoir and Booster Facility will be powered
by a new APS electrical supply. Supporting equipment
included to accommodate power supply.
o New generator facility.
o New Motor Control Facility housed in pre-fabricated
temperature-controlled structure.
o Site Lighting.
o Work to support the powering and control of all equipment.
o Radio SCADA
o 24” Reuse Effluent Pipeline
In general, the new ductile iron 24” reuse effluent pipeline is laid out as
follows: From the tie-in at the existing fire hydrant at the south east
corner of the facility, the 24” pipeline runs along Roeser Rd. to Estrella
Pkwy. Just west of Estrella Pkwy, the pipeline makes a 90 degree turn and
runs south along the road, notably over the 96” APS Palo Verde Pipeline
and the Buckeye Water Conservation and Drainage District Canal to just
north of the bridge over the Gila River. From here, the pipeline crosses to
the east under Estrella Pkwy, and runs south to connect to the outer curb
of the pedestrian walkway of the bridge that spans the east side of the
bridge. The pipe hangs from the walkway and spans over 1,000 feet to a
rip-rap stilling basin to be located in the bottom of the Gila River.
Portions of the pipeline have already been constructed, as shown on the
Drawings.
The work on the Estrella Pkwy Bridge may be constructed from the bridge
and/or from the Gila River bottom at the discretion of the Contractor. For
any Work completed in the River, a defined easement has been included in
the Drawings to show the limitations of Work and access. This easement
will become a permanent access road for the City at the completion of the
Project.

Reclaimed Reservoir and Booster Facility
PROJECT NO. WW00403
Questions received January 4th through January 13th, 2010:
1. Will you modify your bid forms to show the pricing for both the cast-in-place and
prestressed concrete tanks?
1.A: No.
2. Invitation To Bid, Page 12 indicates a City of Goodyear Transaction Privilege Tax. Is
this tax in addition to the Arizona Sales Tax and may we have the amount or
percentage for this tax?
2.A: This is the same with any construction contract, state & County .063, City .035,
tax basis is .65of the taxable income.
3. Since it is our understanding that this is a prevailing wage project, may we have the
General Decision Wage Rates applicable to this project?
3.A: See Addendum No. 2.
4. May we have confirmation that the warranty for this project is one year?
4.A: See Supplemental General Condition No. 2
5. Specification Section 13209, Page 3, Paragraph 2.1, Design Criteria – May we have
both the overflow and venting design flow rates?
5.A: Specification Section 13209 modified. See Addendum No. 3.
6. The Bid Proposal Form requires the General Contractor to provide a lump sum price
with no break out items. We would strongly recommend that the Bid Proposal Form
be revised to include a break out price based on providing a prestressed concrete tank
in accordance with AWWA D110, Type III Standards as the basis of the general
contractor’s bid and an alternate add or deduct price for the cast-in-place option as
depicted in the contract drawings. This will allow the owner/engineer the ability to
evaluate the different tank options provided by the general contractors for this project.
6.A: The owner/engineer have already deemed either tank options acceptable, and
have required notification of which option will be utilized at the time of the bid.
7. We would recommend that a place be provided on the Bid Proposal Form for the
general contractors to list the name of the (AWWA D110 Type III) prestressed
concrete tank manufacturer.
7.A: See front end documents, including all addenda, for subcontractor reporting
requirements at the submission of the bid.
IFB-OP 10-1440 Questions – Addendum No. 3 Page 1 of 10
8. In review of the project specifications, there does not appear to be a qualifications
section for the cast-in-place tank option. We would suggest that the cast-in-place
tank experience be similar to the qualification section listed in Specification Section
13209, Page 2, Paragraph 1.3, and Quality Assurance. Please note, Specification
Section 13209, Page 2, Paragraph 1.3, Quality Assurance, would need to be modified
to reflect contractor’s qualifications to construct a reinforced concrete environmental
liquid containment structure such as the cast-in-place tank allowed on this project.
We would recommend that the cast-in-place tank contractor also have at least 15
years experience and at least 20 installations which have been in successful service.
8.A: See Addendum No. 3.
9. Specification Section 13209, Page 3, Part 2.1 A.4 indicates that the floor slab for the
reservoir shall be 8-inch minimum thickness reinforced in accordance with the
requirements of ACI 350-06. We would recommend that the tank designer be
allowed to select the required thickness for the tank floor and utilize a minimum
thickness of 4-inches as ACI 350, AWWA D110, and ACI 372. May we have
confirmation that this is acceptable?
9.A: No change allowed.
10. Specification Section 13209, Page 5, Paragraph 2.3 C.1 indicates that coatings shall
be in accordance with the tank contractor and as specified in Section 09900, Painting.
Please note, we would recommend that a decorative coating as manufactured by
Tamms be provided for this tank. The Tamms decorative coating would consist of
two coats of Tammscoat on the exterior wall and one coat of Tamoseal and one of
coat of Tammscoat on the exterior dome for this tank. This coating has been used by
Natgun and others in the prestressed concrete tank industry for several decades with
success.
10.A: Provide concrete coatings as specified.
11. Specification Section 01416, Special Inspections, indicates that the owner may
employ a special inspector for various components of the work such as concrete,
prestressed concrete, reinforcing steel, etc. May we have confirmation that both
shotcrete and concrete testing will be performed by the owner’s special inspector?
11.A: Specification Section 01416 provides sufficient explanation.
12. Specification Section 13209, Page 7, Paragraph 3.3 D.1 requires the prestressed
concrete manufacturer to perform an internal visual inspection video-taped at the 11th
month hydrostatic retest. However, in Specification Section 01453, Paragraph 3.3,
Hydrostatic Testing of Hydraulic Structures which pertains to the cast-in-place
concrete rectangular tank we do not find a similar requirement for the 11th month
liquid-tightness retest, nor the DVD internal/video-taped inspection. We would
recommend that the 11th month inspection and video-taping be omitted from the
prestressed concrete tank specification section or that a similar requirement be added
to Specification Section 01453.
12.A: See Note 2 - Sheet P/M-2.
IFB-OP 10-1440 Questions – Addendum No. 3 Page 2 of 10
13. Specification Section 13209, Page 4, Paragraph 2.3 B.1 calls out a roof hatch and
that it shall conform to Specification Section 05536. We note that the roof hatch
indicated in Specification Section 05536 is significantly different than what is
typically used for an AWWA D110 Type III tank. May we have confirmation that
the standard Halliday Series F1R4242 or equal is acceptable for this project?
13.A: The Halliday Series FIR4242 will be accepted as an equal for the reservoir
hatch. See Specification Section 05536-2.1.C.11.a.3 and b.3.
14. Specification Section 13209, Page 5, Paragraph 3.1 A. indicates special inspection in
accordance with Section 01416, Special Inspections, Chapter 17 of the 2006 Edition
of the International Building Code (IBC) is to be included in this project. It is our
understanding that the special inspections, which are covered under Section 01416,
will be employed by the owner to conduct the special inspections. May we have
confirmation that the on-site special inspections for the prestressed concrete tank will
be performed by the owner’s engineer?
14.A: Specification Section 01416 provides sufficient explanation.
15. Specification Section 13209, Page 6, Paragraph 3.2 B.1b. and c. indicates that the
interior and exterior wall surfaces shall receive a float finish. We would recommend
that the internal wall panel receive a horizontal light broom finish and the exterior
wall surface shall receive a shotcrete nozzle or gun finish.
15.A: See modifications to Specification Section 13209-3.2.3.1.C in Addendum No. 2,
Item 3. No change to Specification Section 13209-3.2.B1.6
16. May we have confirmation that the tank designer may size the required overflow weir
and its shape? The drawings indicate a minimum 18-foot long rectangular weir,
however, it is normal practice with precast, prestressed tanks that circular weir cones
are used. Is this acceptable?
16.A: The Contractor may modify the shape of the weir; however, the weir length
shall be a minimum length of 18-feet per Specification Section 13209-2.3.B.8.6.
17. I respectfully request approval for the following Siemens products: 1. Section 16442
Lighting and Distribution Panelboards, 2. Section 16423 Motor Control Centers, 3.
Section 16144 Control Stations, 4. Section 16143 Disconnect Switches.
17.A: This equipment is an acceptable ‘or equal’ for the quested products..
18. Please confirm that the walls of the Atkinson Structure are to be 12 gauge walls with
a 16 gauge roof. Their thoughts are that 16 gauge wall panels will easily meet the
400 pounds per linear foot and the 125 MPH wind load required by the spec. They
also shared that utilizing 16 gauge wall panels would be much more economical.
18.A: See Addendum No. 3.
19. I am requesting a finish schedule as to what new and/or existing items will require
Painting. Specific areas of concern: a. What coating will be required on the reservoir
(i.e. Interior, Exterior, Roof, Below Grade)? b. Will piping and mounting brackets
require finish painting at Gila River Bridge? c. Will concrete at Existing Reuse Pump
IFB-OP 10-1440 Questions – Addendum No. 3 Page 3 of 10
Station require special coatings? d. Will Existing concrete Containment area in
Hypochlorite Storage require special concrete coating?
19.A: No additional schedules will be provided. See Addendum No. 3 for clarification.
20. The FRP baffle wall required for the cast-in-place reservoir causes a dramatic price
disadvantage (up to 15% of the cost) to the cast in place option. The baffle wall
should either be required for both types of reservoirs or not required for either.
20.A: No change allowed.
21. It is not possible for the contractors to turn in a CD/DVD with the completed bid form
at the time of bid since the final bid amounts are not determined until minutes before
and then telephoned to the bid runner for submission. It is also more cumbersome to
complete 3 copies at the same time when the City only needs 1 to be opened and
read. As a compromise could the requirement be changed to only turn in 1 set of bid
documents with the stipulation that the low 3 bidders be required to complete the
extra copies and CD/DVD within 24 hours?
21.A: This option is acceptable, the CD/DVD and two (2) copies shall be received at
the location identified for Bids on or before 3:30 January 21, 2010 failure to meet this
requirement will result in BIDDER DISQUALIFICATION.
22. Specification section 15061 B.3.b requires AWWA C110 fittings. Can AWWA C153
fittings be added to reduce the project cost and improve fitting availability?
22.A: See Addendum No. 3.
23. Drawing I-5 indicates the addition of new Pressure Switches at each Reuse pump
however, no pressure switches are indicated in the Electrical drawings or in the
Conduit schedule. Are pressure switches for these pumps required? If so should
conduit and wire be added to the Conduit Schedule so that it may be included in the
bid?
23.A: See E-7, E-14 and Addendum No. 3.
24. The One-Line Diagram for the existing MCC-E on E-5 appear to require the
replacement of the main breaker for each motor starter with a 15A unit however, the
motor starter schematic on drawing E-12, which indicates the modifications required
to the starter indicated no change to the existing main breaker. Should replacement of
the main breaker for each starter be included in the bid? If so please provide
information on the existing manufacturer and serial # of the MCC.
24.A: See E-12 and Addendum No. 3.
25. Specification 16075 refers to the use of “Molded” conduit labels however
Specification 16050 and 16131 requires the use of “Brass” tags for conduit marking.
Please advise if “Molded” conduit labels should be used in lieu or in addition to the
“Brass” tags.
25.A: See Addendum No. 3.
IFB-OP 10-1440 Questions – Addendum No. 3 Page 4 of 10
26. There is a discrepancy in the requirements for the Frames for the Electrical and
Instrumentation manholes. Per specification 16138 the Frames are to be cast iron
however the detail on drawing E-3 indicates the Frame to be Aluminum. Please
advise if Aluminum Frames should be provided.
26.A: See E-3 and Addendum No. 3.
27. 54" RE Line from Reservoir thru Butterfly Valve to 90 Elbow towards "Suction

45.A: Yes.
46. There is a note on Drawing CD-1 to relocate the existing chemical metering pumps
and totes as shown on Sheet P/M-6. There is also a specification for sodium bisulfite
pump (11346). Please clarify if the pumps shown on Drawing P/M-6 are existing,
relocated or new pumps
46.A: See sheet I-8 and Addendum No. 3.
47. Please clarify the location of the Spillway shown on CD-1.
IFB-OP 10-1440 Questions – Addendum No. 3 Page 6 of 10
47.A: See Addendum No. 3.
48. General Note 24 on Sheet G 5 states that “Trees are to be removed and transplanted
by Contractor to Construction Staging Area…” There is a significant amount of
vegetation, trees included, in the alignment of the access road as it enters the river
bottom. Is it the intent of this note to have these trees transplanted to the Staging
Area?
48.A: See Addendum No. 3.
49. The pipe crossing the irrigation canal depicted on Sheet C 11 as existing does not
appear to be in place currently (reference attached photo). Will this piping be
installed prior to commencement of this contract? How much of the underground
portion of the offsite 24” RE depicted as existing is installed currently?
49.A: The piping in question is not part of this Project and is intended to be in place
before the completion of the pipeline installation. Piping may not be installed
prior to commencement of this project.
50. We are assuming that the decorative coating added to the pre-stressed concrete tank
option only applies to this option, not the pre-cast option.
50.A: Provide concrete coatings as specified.
51. No elevations were given for the existing ground at bore logs 1 & 2. From the bore
log information map, it would appear that the bore logs start from approximately
elevation 907. Based on that, the elevation at the “GM” Layer would be
approximately 896 at bore log B-1 and 896.5 at bore log B-2. These correspond 11
and 10.5’ below existing ground surface. The subgrade for the cast-in place option
reservoir footing is 898.75, (8.25’ below grade) or roughly 2.75’ higher than the GM
layer. If Note 1, on drawing S10 is followed, it appears that there is at least 2.75 feet
of material that must be over excavated and replaced with select backfill per 02200-
2.1.B, as that is the material for use beneath structures. Please clarify if this is the
design intent or if the design intent is just to place the reservoir on whatever the
undisturbed subgrade material is at elevation 898.75.
51.A: Top of GM stratum elevation varies, but is within 18” of the bearing elevation
of reservoir base slab and footings at boring B-1 and within 12” at boring B-2.
The distance between the bearing elevation and top of GM stratum may vary at
other locations but is likely to be in the same range. Footings and base slab
may rest directly on natural grade if the bearing stratum is deemed suitable by
the Geotechnical Engineer. If not, unsuitable material shall be removed to a
depth determined by the Geotechnical Engineer and replaced and compacted
per his recommendations.
52. Are the CAD files available for take-offs?
52.A: No.
53. Sheet C-7 shows a note 5 for a 4” air/vacuum release valve. However it is not noted
anywhere on the plan or profile view. Is there to be an air release valve on this page?
IFB-OP 10-1440 Questions – Addendum No. 3 Page 7 of 10
53A: See Addendum No. 3.
54. The response given for question #4 in Addendum 2, related with MOPO 8, mentions
to provide and operate temporary pumping facilities. If the facility can’t be shut
down for 120 hours, please provide flow rates through the reuse effluent pump station
that would have to be temporarily pumped to the new reclaimed reservoir so that the
size and quantity of pumps required for this temporary pumping can be determined.
54.A: Temporary pumping facilities must be able to convey at least the total combined
design flow of all pumps being installed at the Reuse Effluent Pump Station as
part of this Project (4,800 gpm). See Addendum No. 3.
55. At the reuse effluent pump station, can the north or south pumps (3 at a time) be shut
down and still handle the flow through the reuse effluent pump station so that the
installation and testing of the new pumps and piping be done in stages three at a time.
55.A: No. The existing pumps are not reliable enough to do a staged replacement.
See Addendum No. 3.
56. Would aluminum pedestals (Dwg. E-2) be acceptable in lieu of the hot dipped
galvanized steel?
56.A: No.
57. Specification 16137-3.2.D states a 3” separation between conduits and the Ductbank
detail on Drawing E-3 indicates a 2” separation. Which is correct?
57.A: Per 16137.3.2.D, there shall be a minimum 3" separation between conduits
and the outer surface of the ductbank. Please see detail on E-3 for spacing
requirements between conduits for 480V/120V, analog and 12KV.
58. Specification 16137-3.2.I indicates rebar reinforcement at roadways only however the
Typical Ductbank detail on Drawing E-3 indicates rebar reinforcement in all encased
ductbanks. Is rebar required in all encased ductbanks or only under roadways?
58.A: Rebar reinforcement is only required in ductbanks routed under roadways.
59. Specification 16137-3.2.I indicates rebar reinforcement to be provided as #4
longitudinal bars at corners only. The detail on Drawing E-3 however show #5
longitudinal bars at corners and #4 hoops at 12” on center. Please clarify which is
correct.
59.A: See E-3 and Addendum No. 3.
60. Conduits P014, P015, P016, P017, and P018 between the ATS and the Generator
each contain 3-750kcmil and 1-250kcmil ground wire. As the Generator is only rated
650KW (1200A) should (2) of this conduits be provided as empty spares instead?
60.A: See E-13 and Addendum No. 3.
61. During the engineering phase we had worked with Malcolm Pirnie on pump
selections with Fairbanks Morse, however, on the pump referenced above we had
recommended that they go with our model 4” 5824 split case pump, 1800 RPM and
IFB-OP 10-1440 Questions – Addendum No. 3 Page 8 of 10
100 HP motor. Since that time Fairbanks has decided to no longer produce the 5800
series split case pumps under 12” size because the castings are just way to expensive.
We could never meet the 75 HP or 8” minimum suction requirements as specified.
This causes a few problems with relation to the existing specifications not just for
Fairbanks Morse but for also for Gould’s, Aurora and Paco Pumps. None of us can
meet the requirements of the 1800 RPM maximum speed, the 8” minimum size and
the 75 HP Motor. The only factory that “perhaps” has a fit is Peerless Pumps….but it
appears marginal to the 75 HP motor requirements for non-overloading. If they can
do it then effectively this is a sole sourced bid opportunity for Peerless Pump. Our
recommendation to Malcolm Pirnie and to Goodyear is to keep the motors at 75 HP
(so no electrical changes are required) change the speed to 3600 RPM and the
minimum suction size to 5”. Those changes will allow for all the named suppliers to
bid the project giving the City of Goodyear the best opportunity for a competitive
price.
61.A: Specification Section 11120 Modified. See Addendum No. 3.
62. Article 2 Contractor’s Responsibilities, paragraph 2.15 states that “The City has
obtained certain required permits which are included in the Project specifications, but
it will be the duty of the Contractor to determine that all the necessary permits have
been obtained.” I don’t find a list of permits that the City has obtained anywhere in
the specifications. Can you clarify what permits have been or will be obtained by the
City?
62.A: An allowance has been added as part of Addendum No. 3 for all permitting
fees.
63. I forwarded the spec section for the pollution liability insurance to our insurance
company, and they have never heard of this requirement. They have requested more
information on what type of hazardous substances the City of Goodyear is looking to
have coverage on. The price for this insurance could be quite expensive and they are
questioning the need for it.
63.A: Pollution insurance is standard on all City projects, it is required.
64. Z-25 wrap up insurance. This is a very complicated program and we do not have this
in place nor do moth other General Contractors. This is what we got from Liberty
Insurance, our insurer: Rolling CCIP programs are very sophisticated and require a
great deal of admin, both on our part, the customer, and a broker where applicable.
Most contractors, with the exception of the largest GCs, do not have this type of
program. We have participated in OCIP programs where the Owner has this wrap up
insurance. Can you please clarify further if this is needed?
64.A: The Z-25 wrap up insurance will not be required for this project.
65. Are APS drawings completed and available?
65.A: No.
66. Is the contractor responsible for primary electrical at the tank area? If so, how far is
the primary feed?
IFB-OP 10-1440 Questions – Addendum No. 3 Page 9 of 10
66.A: We are designing for a 480V 3-Phase service according to APS policies and
procedures.
67. Is the contractor responsible for APS fees? If so, can we eliminate from bid and just
go on a reimbursable basis?
67.A: An allowance for permit fees has been established. See Addendum No. 3.
68. On Page CD1, where is the spillway in relation to the whole project? What is the
spillway constructed of? Is there any other information available for this spillway?
68.A: See Addendum No. 3.
69. Per the documents, the contractor is to pay for construction water. Can you give me a
price per 1000 gallons to purchase the reclaimed water that I would think available at
the site?
69.A: Reclaimed is $1.78 per 1000 gallons for dust control.
70. Site wall replacement is shown in the plans (Sheets S5 and S6), but there is no spec?
Please advice if the Masonry spec will be included in future addendum.
70.A: See Sheet S-2.
