(f) Past Performance Information in the SIR and Amendment 0001.

32. QUESTION: It appears that the Subcontractor’s PPS’s will be utilized in determining award. Typically we would receive subcontract quotes from multiple subcontractors and the low bid utilized. Since we have no way of knowing how a Subcontractor will fair in your PPS’s review and what value you will assign said Subcontractor that assessment could lower the value of our bid. We suggest that we be allowed to submit the low Subcontractor as our base bid, with alternate subcontractors included as additives that you may select if you deem that sub the best value. Would this be acceptable?

ANSWER: The Government will be selecting an offeror, which provides the best value to the Government. Since this will be a firm fixed price contract, the Government will not be accepting alternates for the subcontracting team.

The 480V panel feeds the Flight Sim, and also used to feed the GOB building. There should be some capacity after the GOB was demoed. The transformer can be used but OCAT needs to approve. See attached photos.

52. QUESTION: The specifications Section 00411 Pool Subcontractor Prequalification states: “General Contractors may only utilize Pool Contractors approved by formal addendum. Failure to list an approved Pool Contractor will result in disqualification of the entire bid.”

The pool subcontractors are required to submit this 14 days in advance. Addendum 1 requires the Pool Subcontractor to submit a PPQ survey to owners.

74. QUESTION: I am getting turned down on getting hoist & crane quotes for this project. The issues are that in the crane specifications section “1.2-B-7& 8” ASME NOG-1 & NUM-1 specifications are listed which are for Nuclear facilities. It is going to be very hard to find any manufacturer to meet those specifications.

I am also having trouble finding a hoist manufacturer that will quote me hoist rated for human lifting. We can ask to see if at least they can take exceptions to those specifications listed. Let me know how to proceed.

ANSWER: The overhead bridge crane must meet the project requirements to safely lift and move equipment containing humans into and out of the water tank. Final design and safety criteria shall be left to the expertise of the crane manufacturer and shall meet the occupancy requirements.

75. QUESTION: What code is the tank required to be built to? (AWWA, NFPA, etc…). This code will affect manway quantity, hatch sizing, etc… It will also affect the weld process for erection.

ANSWER: Tank will be designed to AWWA D103-09. See Spec section 131500: 2.7 in Addendum 001.

76. QUESTION: What coating system is required? Is high corrosive paint going to be required?

ANSWER: Tank shall be rated for use with chlorinated water. See Spec section 131500: 2.7 for details.

77. QUESTION: Drawings depict a bolted/riveted tank, is this what will be required?

ANSWER: No, the tank is not required to be bolted.

78. QUESTION: We assume based on the drawings this tank will NOT be used for drinking or fire suppression, and WILL be used for the pool portion. Which makes me believe the coating will need to be able to withstand the elevated chlorine levels not normally found in potable and/or fire suppression system tanks. Tnemec should have a coating to meet this need, however IT MAY NOT meet potable water drinking standards and there will be a dramatic different in cost between the two. Please can you confirm if the tank has to be built to potable water standards and provide a coating system?

ANSWER: The holding tank will not be used for drinking water or fire suppression. Tank shall be rated for use with chlorinated water. See Spec section 131500: 2.7 for details in Addendum 001.

94. QUESTION: Addendum 3 answered questions in regards to listing out of approved pool and mechanical, electrical subcontractors as basically at your discretion based on the surveys provided, however the specs state that the pool subcontractors approved to bid would be listed out in a forthcoming addendum. Why would this not be the case also for the mechanical and electrical subcontractors if they also first meet approval by the survey reviews?

ANSWER: The approved Pool Subcontractors for this project are listed in Question #121. The Mechanical, Electrical, and Pool subcontractors the General Contractor proposes to use for this project are required to submit past performance surveys and evidence to show that the PPS was provided to the primary reference by no later than 10 days prior to the SIR closing date… that will be used to determine which team will provide the Best Value to the Government for this project.

Is there a Research Tank spec? Also is there a holding tank specification? The SP sheet that has the most details regarding the holding tank is mainly on the foundation aspects of the tank, I can find no spec that refers to approved manufacturers/suppliers of the actual holding tank and it’s components.

ANSWER: Spec section 131500 has been updated and has the holding tank spec. There was not intent for a Spec Section 131520 in Addendum 001.

ANSWER: Discharge of recovered waters must meet municipal and state regulatory requirements and must be discussed in the contractor’s SWPPP. Also, groundwater encountered during excavation activities must be periodically sampled for volatile organic compounds (VOCs). If VOCs are encountered during construction activities, the contractor shall contact the Contracting Officer Representative (COR) and the Office of Environmental and Occupational Health and Safety (EOSH) to determine if mitigation is required.

105. QUESTION: We request the Geotech Report. We are assuming it will show us how we treat the sub slab underneath the Research Tank. It appears on the drawings that there is a 2’2” mud slab under the Tank with an aggregate base between the mud slab and Tank slab. Can you provide the Geotech Report and provide guidance on how we treat the subgrade underneath of each and every tank?

ANSWER: The Geotech Report has been provided with Amendment 0004. Per note 8 on PS1.02, the research tank pool slab shall be constructed on a minimum 12” thick zone of clean granular drainage fill material above the underlying soils. The granular drainage fill material shall be placed over reconditioned and approved native soils or additional controlled engineered fill material. The Geotechnical Engineer shall determine if the exposed subgrade soils are acceptable to support the research tank below pool slab fill material, or if unstable or unsuitable soils exist which require removal and replacement with controlled engineered fill material. See Detail B-PS1.02 for additional information. A mud slab is not indicated or required.

106. QUESTION: We also believe the Geotech will indicate the building itself is undercut 3’ and brought back to grade with some kind of select. Can you provide guidance on this?

ANSWER: Refer to FOUNDATION NOTES on sheet S-001 and referenced Geotechnical Report for known subgrade requirements.

107. QUESTION: Please confirm, this project is not tax exempt, correct?

108. QUESTION: Reference PS 1.02 Note 6 which mentions a minimum of 24” of drainage fill behind the walls. Then it goes on to say in 22 that the fill material will be either a crushed rock. Is it the intent that the entire excavated area outside the walls will be backfilled with the Aggregate material as described, and that no select fill will be allowed?

ANSWER: The FAA believes this is referencing note 9 and NOT note 6 for this question. The minimum 24”of granular drainage fill material is at the base of the wall and is intended to extend up at an angle away from the wall as defined in the Geotechnical Report. The entire area as defined in the Geotechnical Report shall be backfilled with the granular drainage material as indicated in note 9 on PS1.02 and defined in note 22 on PS1.02.

109. QUESTION: In the past some projects at Mike Monroney have been tax exempt and some have not depending on buildings being owned by FAA or by the City of Oklahoma. I have been unable to find tax requirements in Solicitation documents to whether this project is tax exempt or not.

111. QUESTION: The fixture schedule on sheet P-001 states that sink P-4 is a “solid surface lavatory” and to reference the architectural drawings. Detail 4/5 on sheet A-221 illustrates a “drop-in” sink contrary to the integral sink stated in the plumbing drawings. The cost difference between an integral sink and a drop-in sink is between $50 and $200/sink. Please advise whether sink P-4 shall be an integral sink or a drop-in sink. In either cases, we will need a specification issued.

ANSWER: Integral sink to be used at all vanities. Size and shape called out in spec section 123661.16.
