Question_65-75.pdf

65. Question: Drawing FX001 indicates a 135 PSI at 2000 Gpm fire pump & the available water flow near building 264 is 118 PSI static and 70PSI residual at 2755 GPM. This water pressure is at an elevation approximately 40 feet above the building elevation. So with this fire pump and the adjusted available water pressure the static pressure on the fire protection system will be 285 PSI. This is well over the 175 PSI maximum per NFPA. Are we allowed to reduce the fire pump size?

Or are we to include a pressure reducing valve downstream of the fire pump?

65. Answer: We estimate the static pressure at the Hangar Building fire pump will be 291 psi. Pressure reducing valves are to be located downstream of the fire pump for the foam system, and also for the sprinkler systems to maintain pressures below 250 psi for the foam system, and below 175 psi for the sprinkler systems. See Detail A1 on Sheet FX601 for location of the pressure reducing valves.

66. Question: Part 2.2.2.1 says that failure to provide a letter of commitment from a proposed major subcontractor will be noted as a significant weakness. Please either (1) confirm that letters of commitment are only required for subcontractors whose project experience is submitted under sub-factor 1, sub-element 1, Demonstrated Experience; or (2) provide a list of "major" subcontractors that require a letter of commitment regardless of whether their project experience is used in sub-factor 1, sub-element 1.

REF: RFP page 27.

66. Answer: Contractors must provide a letter of commitment from proposed major subcontractors or it is a significant weakness. Per page 20 paragraph 2.5.2.2.12 If any portion of the work provided as demonstrated experience is subcontracted, clearly identify that work as such and provide the required experience of that subcontractor as it relates to work the subcontractor is to perform. You must provide a commitment form for subcontractors (Exhibit D and also Exhibit B). It is the prime contractor’s choice to use the subcontractor as demonstrated experience for a specific requirement listed under demonstrated experience.

67. Question: Part 3.4.3 calls for additional QC personnel in the areas of Electrical, mechanical, civil, structural, architectural, materials technician, and submittals clerk. However, the experience matrix lists an additional QC person in environmental. Is this additional QC person required? REF: Section 01 45

00.00 10

67. Answer: The environmental component of the project is primarily related to the demolition of the two existing facilities. The QC requirement for Asbestos work, involving the removal or disturbance of asbestos, can be met by having an on-site EPA-accredited/TN-licensed asbestos Supervisor, managing asbestos workers. In addition, once general demolition work begins, involving the disturbance of lead-paint, Contractor is to have a ‘Competent Person’ on-site, meeting OSHA requirements for a “Competent Person” to recognize lead hazards, be familiar and experienced with the OSHA lead standard (29 CFR 1926.62), and have authority to take corrective actions to protect personnel from lead hazards.

68. Question: The experience matrix in Part 3.4.3 calls for a QC person in environmental and requires a Graduate Environmental Engineer with 3 years experience. As an alternative to employing the services of a graduate environmental engineer, could a certain number of years in related environmental construction experience be considered an acceptable substitute?

69. Question: In Section 12 59 00 Paragraph 1.2, there is a mention of Refurbished Furniture Systems as part of the Product Data Submittal (SD-03); however, no other reference to refurbished furniture is found in this Section. Please advise if refurbished furniture will be considered, and if so, please amend said Section to include information defining its use in the project. REF: SECTION 12 59 00.1.2

69. Answer: Refurbished furniture shall not be priced in this solicitation. It will be bid at a later date

70. Question: Please either (1) confirm that contractors are not permitted to purchase the FF&E package on GSA pricing schedule or (2) provide authorization to use GSA pricing for the FF&E package. REF:

Section 125900

70. Answer: FF&E was removed from the solicitation. It will be bid at a later date.

71. Question: FF&E vendors have inquired about the availability of CAD files to aid in their quoting.

Will CAD files be made available prior to bid? REF: Section 125900

71. Answer: FF&E was removed from the solicitation. It will be bid at a later date.

72. Question: Please confirm that the contractor is not responsible for leveling, anchoring, or otherwise installing equipment that is listed in the Shop Equipment Legend only to be moved by the Government but not moved or installed by the contractor (such as Supply Lockers E127.7). REF: I-103

72. Answer: Assume that only items indicated as Contractor Install will require leveling and anchoring per Shop Equipment General Note.

73. Question: Details D1/CS504 and A5/CS505 do not provide size (4" , 6", etc.) or weight (Sch. 40, 80, etc.) information for steel bollards. Please advise. REF: D1/CS504 & A5/CS505

73. Answer: Schedule 80 steel pipe 6” OD

74. Question: Typically wood doors are factory-finished but the Door Schedule provided on A-601 calls for all doors to receive a field-applied epoxy paint. Please verify that all wood doors shall receive a PE-3 finish (field-applied epoxy paint) and SHALL NOT receive a FF-1 finish (factory finish) per the Door Schedule. REF: A-601

74. Answer: Wood doors should be factory finished (RE: Specification 08 14 00 – 2.3.6) to match WD-1 per specification 09 06 90 - 2.3.5.4. Wood Doors shall not be field painted. Door 148A shall be revised to a Wood Door instead of Hollow Metal.

75. Question: In specification section 08-11-12 2.2.1 indicates Blast resistance requirements in accordance with UFC 4-010-01 with peak pressure corresponding to Explosive Weight II, please provide the “Peak Overload Pressure” to be met in PSI.

75. Answer: Could not find section 08 11 12 in bidding package, however, section 2.2.1 is in specification 08 44 00, please confirm this is the specification section that is being referenced in the question. Information related to the blast resistance requirements are already included in the documents by providing the standoff distance in the civil drawings, the required explosive weight, and the UFC references. Glazing supplier/designer is responsible for developing pressures based on the provided information.
