1) For some of your types, I was wondering if we can offer an alternative lighting fixture to one we represent?

Answer: The FAA does not pre‐approve products from suppliers. Products are considered when the general contractor submits them for approval in accordance with the contract documents.

2) As a product manufacturer, what process do we follow to request equivalency for our product?

3) Per the project announcement, set‐aside is total small business ($36.5 Million Company). Is this a requirement for ONLY the Prime Contractor or does it relate to the subcontractors of the

Prime Contractor?

Answer: Refer to contract clauses 3.6.1‐1 Notice of Total Small Business Set‐Aside, 3.6.1‐3

Utilization of Small, Small Disadvantaged and Women‐Owned, and Service Disabled Veteran

Owned Small Business Concerns, and 3.6.1‐7 Limitations on Subcontracting.

3.6.1‐1 describes the small business set aside (awardee must be a small business based on

NAICS code for project). Regarding subcontractors, 3.6.1‐3 requires the contractor to subcontract with small businesses to the fullest extent possible. 3.6.1‐7 describes how much work the prime has to perform on the contract (15% or 25% depending on the type of contractor that is awarded the contract).
