Solicitation Number 36C25219Q0048 Hydronic System Repairs – Questions & Answers

Question: Task 1 reflects “replace (1) failed non-repairable Air Compressor #1 and repair (1) partially operational Air Compressor #2”, which are located in the basement of Building #1. Is there any indication what repairs may be required for Air Compressor #2? Obviously from a bidding standpoint, without specific information, it might be determined by the contractor to simply include the costs of a new air compressor, rather than rolling the dice on the cost of unspecified repairs.

Answer: Statement of work has been revised. Contractor shall replace both Air Compressors.

Question: In performance of Task 1, are we to use the same plywood ramp which is placed over the stairs in the removal and replacement of Air Compressor #1?

Answer: No.

Question: Can you specify which elements of Task 3 are being revised? There was discussion about removing the hot water coil from the scope of work, but leaving the heat exchanger in the scope of work.

Answer: There was not revisions to Task 3. Task 2 has been revised as follows:

Deleted: Remove and replace (1) hot water coil.

Added: All disturbed hydronic loops to be filled with 40% propylene glycol, corrosion inhibited.

Added: Flange gaskets shall be EPDM with a temperature range of -40⁰F to 250⁰F.

Added: Remove and replace approximately 60-ft of insulation and install heat trace along the exterior pipes for AHU first floor entrance heat.

Question: Can you provide specific information regarding crane access associated with the replacement of the chiller located on the roof of Building 1 (Task 4)? There was speculation a CT trailer is often parked in the area which would prohibit crane access, and even further speculation relative to the times in which crane lifting may be allowed or scheduled.

Answer: Per Statement of Work Part 3, Crane lifts, any work that closes drive isles, closes building entries or closes public corridors shall be during low patient time and performed Sundays.

Please provide or reference any measures required of the contractor as would apply to the performance of work near or adjacent to ongoing medical operations. Task 3, for example is adjacent to areas in which ongoing medical care is active.

Answer: The Contractor shall provide mitigating activities as outlined in the Construction Safety Precautions and Construction Infection Control Risk Assessment / Dust Control Precautions Including but Not Less Than The following:

a. Fire extinguishers, pedestal mounted in the area of work

b. Walk off dust mats, inside and outside all entry / exit points to the workspace, changed not less than daily or more as required by the construction or COR.

c. Block off all HVAC return ductwork and lovers so not to introduce dust into the HVAC system.

d. Provide a plastic dust tight temporary construction barrier to isolate the area of work.

e. No trash, used packaging, or construction spoils shall be stored on site. Remove each day using covered gondolas.

f. Broom sweep the work area at the end of each day. Provide HEPA vacuum and damp mop daily where broom-sweeping creates airborne dust.
