Specification 09 67 23.15 should be deleted from project. No requirement for this remains.

22. Question: Floor finish types RES-1 and RES-3 are listed as options for a significant portion of the work. Specification 09 67 23.13, Sections 2.2.3.2 and 2.2.5.2 - "System Components", describe a conventional double-broadcast epoxy quartz aggregate system. Section 3.2.2 - A"pplication of Prime Coat and Troweling", describes a conventional epoxy quartz slurry trowel system. Please advise which application method should be used: 1) Double broadcast OR 2) Slurry Trowel. Reference 2.2.3.2, 2.2.5.2, 3.2.2 / 09 67 23.13

22. Answer: Double- Broadcast epoxy quartz is the preferred application method.

23. Question: Section 14 under 00100 lists "Brand Name Requirements" but it appears that the second item "Hight Expansion Foam Concentrate System and Fire Releasing Optical Detection System" was intended to read "High Expansion Foam Concentrate System and Fire Releasing Optical Detection System", which is a type of fire suppression system and not actually a Brand Name/Manufacturer. Is there a specific Brand/Manufacturer requirement for the high expansion foam concentrate and fire releasing optical detection system? Reference Section 14 / 00100 Notes

23. Answer: We were unable to find a reference section 14 / 00100 Notes. However, Specification 28 31 76 sections 2.10 and 2.15 require the foam detection and release systems to be Det-Tronics brand.

Specification 21 13 25.00.10 sections 1.18.e and 2.10 indicate the foam concentrate must be Ansul JetX two percent. Other foam system equipment such as foam generators must be listed for use with Ansul JetX foam concentrate per section 2.15.

24. Question: The lead-in riser pipe for the building fire protection system is calling for a 12” welded stainless steel pipe. Typically underground piping is run as ductile iron pipe into the building and stops 1’-0” AFF with a flanged piece. There are no NFPA requirements stating that this lead-in riser pipe is required to be stainless steel. Are there special soil conditions that may be driving this? Please advise if ductile iron pipe can be used in lieu of stainless steel pipe. Reference A1/FX601

24. Answer: A stainless steel in-building riser is required as indicated in the contract documents. See FX601/Detail A1 and Specification section 21 13 13.00 10, 2.4.1.

25. Question: The above ground piping requirements listed in Specification 21 13 25.00 10 seem to be atypical for a high expansion foam concentrate fire suppression system. There are no NFPA requirements that state this piping needs to be stainless steel; however, Section 2.6 of Specification 21 13 25.00 10 specifically requires stainless steel piping. Typically, stainless steel pipe is used for the portion extending from the foam tank to the proportioner (see attached), but all other piping is usually galvanized steel.

Also, the inlet side of the foam system from the main feed is usually galvanized steel. Please verify that stainless steel piping should only be used as stated above and as shown in the attached document and that galvanized steel piping can be used at all other locations. Reference 21 13 25.00 10, Section 2.6

25. Answer: Specification 21 13 25.00 10, Section 2.6 is for HEF concentrate piping only and requires stainless steel piping and fittings. It does not apply to foam solution piping. Foam solution piping is specified in Specification 21 13 25.00 10, Section 2.5.1 which refers to Specification 21 13 13.00 10 and in Section 2.5.1 calls for Schedule 40 black piping. Galvanized piping is not allowed for foam concentrate or foam solution piping or fittings.

26. Question: Specification Section 07 81 01 section 1.2.1.b indicates intumescent paint is required for column row 10 and for columns 10-A through 10-K. The phrase “but is not limited” is included in the list of items. Please provide a marked drawing that highlights all items that require intumescent coating.

26. Answer: The beams supporting the concrete cap slab as well as the underside (steel decking) of the concrete cap slab over Paint Booth Room 133 shall receive a 2-hr intumescent coating per note on detail A1 on A-314. The underside (steel decking) of the concrete cap over Electrical Room 138 shall have a 1-hr intumescent coating. No other beams, or slabs to receive the intumescent fire proofing coating

27. Question: Floor finish CS-1: this designation is used as the basis for the majority of the project floors.

I am unable to locate a specification associated with CS-1. Can you please provide guidance as to the material/system intended for use as CS-1?

27. Answer: Refer to specification 03 30 00.00 10 for Floor Hardener.

28. Question: Floor finish EF-1: this designation is used in a half dozen rooms. The only specification I can locate is Section 090690 | 2.3.1.1 “Sherwin Williams, Light Grey” Can you please provide guidance as to the makeup of the material/system intended for use as EF-1?

28. Answer: Base bid for room 116, 117, 118, 137, 138, 139 should be CS-1. EF-1 is a bid option per 00 22 13.00 20 Bid Sheet/CLIN Schedule.

29. Question: Floor finish RES-1 and RES-3: these designations are listed as options for a significant portion of the work. Sections 096723.13 paragraph 2.2.3.2 and 2.2.5.2 System Components describe a conventional double-broadcast epoxy quartz aggregate system. Section 096723.13 paragraph 3.2.2 Application of Prime Coat and Troweling describes a conventional epoxy quartz slurry trowel system.

Can you please confirm which application method is to be used, double broadcast or slurry trowel?

29. Answer: Double- Broadcast epoxy quartz is the preferred application method.

30. Question: Section 096723.15 describes Fuel Resistive Resinous Flooring, 3-Coat System. Can you please provide a list of rooms, if any, that are to receive this floor coating system?

30. Answer: Specification 09 67 23.15 should be deleted from project. No requirement for this remains.

31. Question: Specification section 07 26 27, paragraph 3.6, a&c states that the owner will engage the testing agency to perform tests and inspections for fluid applied air barrier. This is appears to be in conflict with section 1. Please confirm that the contractor is not responsible for this test and clarify that all other tests and inspections are the responsibility of the contractor.

31. Answer: Contractor is responsible for all air barrier and related tests.

32. Question: Section 03 20 00, paragraph 3.3 indicates that dowels may be installed prior to concrete being placed. However, detail C3 indicates that “dowels shall be epoxied into drilled holes having a diameter of 1/8” larger than the dowel diameter. Please confirm that the dowels may be installed at the time of concrete placement in lieu of drilling every dowel.

32. Answer: Answer assumes question is in regard to the hangar bay slab area detailed on the civil dwgs.

Hangar bay slab area that is detailed on CP103 (or any of the CP100- CP112 sheets), the dowels shall all be drilled into the concrete after placement as required by the noted details. Bid per plans and specs. See structural drawings for all other building slab concrete details.

33. Question: In section 07 42 63, paragraph 1.2 there is a reference to 3-hour fire rated insulated metal panels but the life safety plan LS101 does not indicate the exterior walls to be-3 hour fire rated. Please clarify whether all exterior panels are required to be 3-hour fire rated.

33. Answer: No 3-hour fire rated panels in project.
