FA448620R0014 Renovate Building T-715 Questions & Answers

1. Are TAA (Trade Agreements Act) And BAA (Buy American Act) materials required to be provided under this project? References to both are included in Section K of the solicitation, namely on page 35 (parag. (2) (iii) and page 29 (parag. C (XX)).

A: Yes based on DFARS 252.225-7001.

2. In section 01 11 00, Summary Work, paragraph 1.2.1- Project Description it refers that contractor shall deliver a Life Safety Plan.

What will be the schedule of delivery for this life safety plan after the award?

See question No. 4.

3. The door frame F8 side window illustrates a GL-3 glass schedule, which stands for Bullet resistant glass. Kindly confirm the scope of application for this item as it is not being indicated anywhere else.

Frame Type F8 with GL-3 glass is not to be used in this project.

4. In the solicitation document, section C – Description/Specifications/statement of Work it is requested for the contractor/bidder to deliver a Life Safety Plan. To our understanding and unless this project was a design-build project, having a Life Safety Plan as a bidding deliverable will most probably impact the building´s architecture, egress ways, egress doors, fireproofing of walls and others, fire protection systems & equipment, etc, which, in its turn, definitely will change the scope of works.

On the other hand, and in order to assess the project´s accurate scope of works, cost magnitude, and identify possible life safety deficiencies, the UFC 3- 600-01 standard, paragraph 1-12, “PLANNING\2\ (CONTRACT DOCUMENT DEVELOPMENT)/2/” and subparagraphs 1-12.1.1, 1-12.1.1.1, 1-12.13.1, whilst imperatively requesting the life safety assessment determination implicitly turns the Life Safety Plan into a FEED contractual document crucial for the solicitation.
