77. Answer: traffic bearing sealant is to be removed and replaced with new sealant.

78. Question: The response to question #8 in Amendment 1 conflicts with the response to question #6. If the structural roof deck is removed, everything supported by the deck will have to be removed as well. Did you mean remove and replace attached items?

78. Answer: Correct, all items supported by the deck will be removed.

79. Question: In discussion with several abatement firms, they mentioned during the job walk it was discussed the Interior/Exterior structural steel only needed scrapping of peeling paint and cleaning prior to new paint application.

However, Section 09970 Para. 2.2 b,c,d,e,f,g (High Performance Coatings) States in many areas of the structural steel to “remove all existing paint” under surface preparation.

Also sheet A2.1 elevation detail 2 states “existing exterior truss to have existing finish removed, cleaned and repainted.”

Is it the ANG intent to have contractors bid to completely remove all existing lead painted steel surfaces (which will be very costly), or to scrape loose paint, clean and repaint the structural steel with lead abatement only on the welded areas? Please clarify.

79. Answer: see answer #49

80. Question: Demo drawing AD1.1 shows various interior windows to be removed. Architectural Floor Plan drawings A1.1 as well as A7.2 indicate windows “A” through “E”. Please provide details for these windows.

81. Answer: see answer #33 regarding Fall Protection System. See sheet A3.1 for Draft Curtain

82. Question: Specification section 16490 states “process Instrumentation and Control”. It is our understanding that Building 340 supplies the fire loop for the facility; however the specification requires a Variable Frequency Drive controller and other process pump components not typically seen on fire pump controllers. Are we to provide a true dedicated fire pump controller assembly with a Soft Start controller in accordance with UFC 3-600-01, or a Process Pump in accordance with the specs?

82. Answer: Building 340 provides potable water for the facility. The water system served by Building 340 is not a dedicated fire protection system or “fire loop.” Pump controls for Building 340 should be provided in conformance with the project specifications.

83. Will the communication tower be priced as a part of the base bid or should it be in the communication bid item?

83. Answer: The communications tower should be priced as part of the communication bid item.

84. Question: Is there any additional criteria on the new fire pumps that shall be provided at pump house 340? I cannot find much more than sheet C3.7 of the project drawings.

84. Answer: See response to Question #52

85. Question: Is rigid seismic bracing acceptable in lieu of cable bracing?

85. Answer: As it relates to the fire protection, rigid bracing in compliance with NFPA 13 is acceptable

86. Question: On note 2 of sheet FP1.1, it states that all areas of the building shall be covered by the sprinkler system including porte co-cheres and attics, etc. I do not see any of these areas that should need to be covered. Are the attics made of combustible materials or are they metal?

86. Answer: There are currently no areas to be protected that are not shown on the drawings.

87. Question: Shall we adhere to UFC standards or only NFPA plus ETL 02-15?

87. Answer: Specific to the foam system, follow NFPA and ETL 02-15.

88. Question: The specs state that the sprinkler system piping shall be disinfected. The Hi-Ex system piping will be open to the air and may gather miniscule foreign particles. Is there need for this system piping or the wet system piping to be disinfected considering that both systems are non-potable water and not connected to the domestic system except by reduced pressure backflow preventers?

88. Answer: Yes, disinfect the pipe.

89. Question: The specs call out for a preaction valve on the Hi-Ex foam system, but this valve should be a deluge valve. Is the deluge valve acceptable?

89. Answer: They are identical.

90. Question: Are the abort stations for the foam system intended to shut off the foam supply or the entire foam system? Typically the abort stations shut off the foam supply into the Hi-Ex system.

90. Answer: The abort is to close the deluge valve in order to stop water flow.

91. Question: What is to be done with the existing pump to be demolished in bldg. 113?

91. Answer: All items not called out to be turned over to the Government are to be disposed of by the contractor

92. Question: In paragraph 3.6.2 of spec section 15700 it calls out a Site Fire Protection Engineer. Is this person a Government employee or will this be supplied by the contractor? If supplied by the contractor, what are the prerequisites for this title? NICET level IV, PE, etc? It also looks like this person is only required to witness the final testing, is this the case?

92. Answer: This is a TANG representative, not part of the supplier’s staff.

93. Question: Reference drawing A7.2. detail 13. There are windows indicated on this sheet. Are these hollow metal windows? No window schedule was shown.

93. Answer: see answer to #71

94. Question: It was stated that the relocation of the existing equipment to be moved to bldg. 126 should be in the base bid. However, should the work associated with the new electrical, plumbing, and air systems be also in the base bid or under the bid item for Bldg. 126?

94. Answer: All new electrical, plumbing, and air systems scheduled to be installed in Bldg 126 shall be bid under the Bldg 126 bid item.

95. Question: On the plumbing drawing P1.2 there is a note stating “New Water Cooler Installed at same location” Cannot find specification on the new water cooler?

95. Answer: Electric Water Cooler shall be:

P8AC, Oasis Wall Hung, Wheel Chair Accessible, all stainless steel finish.

Supply: Z-8800-LR, Zurn w/wheel handle stop P-trap: Z-8700, Zurn W/C.O. Plug Carrier: Zurn as required

Or equivalent.

96. Question: Please clarify the roof and exterior wall insulation requirements. This information in the bid documents is contradicting – (Reference, and Drawings A5.2 and A5.3).

a. Roof - Spec section 7212 part 2.2-A says to provide R-30 EPS on the roof which would result in an approximate depth of 8.5”. However, drawing A5.3 shows R-30 and 6” insulation which matches the typical thickness and R Value of Polyiso insulation. Please clarify if the roof insulation is to be EPS at 8.5” or Polyiso at 6”.

b. Wall – The specs and drawings call for R-13 Polyiso. This will result in and overall thickness of 2.28”. Please verify if this is correct.

96. Answer: 07212 specifies an Extruded Polystyrene (xps) board insulation for the roof. No (eps) Expanded Polystyrene has been specified. Drawing A5.2 calls for R-30 roof insulation. Insulation depth is not listed.

Provide the Extruded Polystyrene insulation for the roof as specified for R-30.

b. R-13 continuous insulation is specified for the wall. The specifications call for Polyisocyanurate Board.

97. Question: Reference drawing A7-2, Detail 13. There are windows indicated on this sheet but no window schedule is shown. Are these hollow metal windows?

97. Answer: See answer to Question #71
