2021 CONSOLIDATED CONSTRUCTION PROJECTS

QUESTIONS and ANSWERS

As of 8/18/21

1. For the hydrant repair project, the project description calls for a flow test on any “functional repair” work. What constitutes functional repair work and how many flow tests should we allow for if we don’t actually know which hydrants might need work until after we’ve started the repairs?

Answer: At this time, functional repair would only apply to hydrants #18 and #32 which require internal replacement parts as noted under Section 2, Hydrant Repair. Plan on performing two complete flow tests with reports.

2. For flow testing these hydrants, which test do we use, a PITOT test or does it just need to be witnessed by the fire department and base operations?

Answer: Please complete a PITOT flow test and submit reports to include a static hydrant and nearest residual hydrant.

3. Will we have access to all hydrants during the walk through? If not, can someone take pictures of each hydrant so we can verify their condition and manufacture/model?

Answer: The government cannot provide access to all hydrants during walkthrough. Please see file “Hydrant Photos.pdf” for a representative photo taken as well as photos of damaged hydrants #18 and #32.

4. There doesn’t seem to be a specification or model number for the roll up doors or the overhead fire door. Please provide.

Answer: The existing overhead door is manufactured by Overhead Door. The government did not provide a brand or model number for the proposed door, as that would have excluded competition from other manufacturers. Doors need to meet performance characteristics provided.

5. The gutter installation notes call for us to install a gutter compatible with the existing roof panel and per the manufactures installation details. What is the manufacture of the existing roof panel?

Answer: The original drawings for B131 list Butler Construction on the roof details.

6. What is the color of the existing metal eave trim we are supposed to match for the new gutter?

Answer: We do not have documentation on the exact color of the panels. The Contractor shall provide samples to color match the existing building as closely as possible.
