Government Response 05/16/2024

1. The Asbestos survey was done in 1997. Is there another that is more current?

It doesn’t look to be accurate.

ANS: The building was renovated in 2011; the 12 x 12 floor was replaced, stair treads on the stage steps were demolished, all water lines and sanitary lines were replaced. Assume the following ACM: cementitious siding; perimeter soffit (1-G), Building caulking and putties; at doors, windows (not to include new windows installed in 2011) and gutter connections (1-H), and roof penetrations mastics (R-B).

2. At the site visit there looked like there might be foundation difference. Is there a crawl space?

ANS: There is no crawl space hatch or breather vents on the outside, assume there is no crawl space.

3. C-102, key note #7 states to remove all paint from railing and paint “black”.

Does this mean that it needs to be removed to bare metal or remove loose paint?

ANS: Remove to bare metal.

4. Is there a lead survey for the building?

ANS: See Technical Exhibit E.

5. A-201 Key note #6 states to see structural drawings for fixed ladder but it is not available. Also the key note on the drawings is pointing at an exterior light.

ANS: this is a typo, it is supposed to be “hardwood”.

8. 1. Reference Sheet A - 501, Partition System B3 indicates an insulation thickness of 2.5” (R16). However, exterior walls cross section details indicate R19. Typically, R19 in closed cell spray foam has a thickness of 2.9”-3.0”. This appears to be a conflict in requirements. Please provide clarification of spray foam insulation R values or thicknesses required in all exterior walls. Note:

2024 IBC recommends R19 in exterior facing walls.

ANS: Walls indicated as B3 shall have 2.5” insulation, the rest of the exterior walls shall be R19.

9. Reference Sheet A - 101, Proposed Floor Plan reflects a Partition wall section F6, however, there doesn’t appear to be wall cross section detail provided in the drawings. Please clarify what spray foam insulation R value or thickness required in the partition wall section labeled F6.

ANS: See revised drawings.
