15 August 2018

1. Drawing Sheet M051 indicates that there are Existing Hydronic Heating & Chilled Water Pumps. Are these to be removed & replaced or do they remain in place?

Answer: Unless those pumps are exactly what is shown on M500 and listed on M003 "Pump Schedule" they shall be removed and replaced.

2. Is there a contingency budget allocated for unforeseen site conditions?

Answer: No.

3. Drawing Sheet M051 indicates that the existing Chiller will remain, if it becomes unserviceable during the 494 day PoP will the Government or the Contractor be responsible for replacing, servicing, and/or repairing?

Answer: The Government will be responsible if the chiller needs replacing, servicing and/or repairing.

4. CRC-1 (Outdoor Condensing Unit for CRAC-1) is shown on Sheet M101 outside of Room 133 and CRAC-1 is shown on Sheet M201 on Mezzanine above server room. This is approximately a 30-ft elevation rise in piping between CRC-1 & CRAC-1. The basis of designed unit is Liebert Model MMD36E/PFH037AL which does not recommend piping elevation to exceed a 15-ft rise. Will CRC-1 be relocated to meet this requirement or will the Government accept an approved equal to the Liebert unit?

Answer: The CRAC unit is actually located above the ceiling of Server Room 133A, not on the second floor. There is a platform above that space where the unit will be located and it should be less than 15' above the outdoor unit.

However, contractors may submit material that is name brand or equal to the basis of design for the Government to approve.

5. Will Roofing Specifications & Drawings be provided? CLIN 0006 requires roof repairs to B777 – what type of roof is this? Specifically, what repairs are required for the roof at B777?

Answer: See Addendum 3 which deleted the requirement for B777.
