1. In SOW, Specific Requirements Point A, what is the basis of design for a barrier that meets the requirements of being heat-activated such that it breaks apart or collapses prior to activation of the existing FSS? Heat activated implies a system that is ‘active’ with something like thermal sensors and the ability to move or collect a barrier. Are you looking for a net or filter fabric that burns away or a more involved system?

The barrier material shall contain seams or like that will fail during a fire and as such, does not impact the ability of the sprinkler discharge from reaching the area being protected.

2. In SOW, Specific Requirements Point B, what specific NFPA/UFC codes are being referenced? For example, in NFPA 25, 5.4 it is stated that sprinkler heads should never be covered. The specific requirements of this job are to put a barrier between the sprinkler and it’s coverage area which makes compliance seemingly impossible.

UFC 3-600-01 applies. In additon, barrier material shall be classified by UL to 723S, tested and approved, for installation below sprinklers and meet NFPA 13 for drop ceilings.

3. In SOW, Specific Requirements Point A, how far below the 100’ ceiling is the fire suppression system and the light fixtures? Effectively, what height should this barrier be mounted?

6-8 feet. As specified in the RFP.

4. What does access look like to reach the 100’ ceiling? Will mobile equipment be able to access that height? Will scaffolding be able to access that height?

See attached picture (Ceiling Area_Typical). Mobile equipment or scaffolding can access that height.

5. In SOW, Specific Requirements Point D, you suggest a size of 30x60 then also suggest you would like a larger barrier. What size is required?

As specified in the RFP.

6. How large is the falling debris? What quantity? What frequency? How much debris should the barrier be expected to hold over a 2-3 year period both is size and weight?

Paint chips smaller than a dime, although occasionally the size of a credit card. Quantity/frequency indeterminate, could be daily in some amount. Contractor determined.

7. In SOW, Specific Requirements Point E, it is required that pits be covered. How large are those pits in area, depth, and what possible combination of things can be used to cover them? For example, can supports be placed in the pits to help with coverage?

The diameter of each pit is approximately 100 inches. Contractor determined. No supports can be placed in the pits.

8. Will this area remain occupied during the installation of the cover and barrier? If so, what schedule considerations must be made by the contractor?

Yes. Building normal working hours are: M-Th 0600-1530, Fri 0600-1430 (Alternating Fridays).

9. The listed FAR clause for purchase and pay is 52.212-4, that applies to commercial items but not construction work such as the installation of this barrier. Will construction FAR clauses, such as 52.232-5, be considered?

This will not be a Construction contract, clauses do not apply.
