Amendment 04 January 8, 2021

SSC # 2018-202

SPECIFICATION:

1. Per 12/7/2020 pre-proposal conference call, it was mentioned that Submittal Exchange will be handled and paid for by the AE. Please confirm the cost of the submittal software will in fact be handled outside of GC contract.

Answer:

Submittal specification (Section 01 33 23 -1) clearly states the AE is responsible for setup of submittal exchange. GC will work with AE for proper levels of access.

GENERAL INFORATION:

1. Per drawing sheet G0.1, note 20: Paint all exposed new and existing piping, conduit, wire mold, electrical panels, access panels, etc., to match wall finish unless otherwise noted.

Answer:

Not required in penthouse mechanical room.

2. Can the VA please provide the life safety drawings and code information sheets?

The Truman VA is currently under a different contract to correct Fire Life Safety Deficiencies. The attached drawings are for your reference and will reflect the most accurate changes.

MECHANICAL:

1. For AHU-S4, the static pressures listed look like a copy paste of AHU-S3 and there are no pressures listed for the return fan. The motors are also not NEMA standard motor sizes, 10HP and 5HP would need to be used. When I try a selection for the supply fan, the only selection I get would need 20HP per fan, so I doubt the numbers for AHU-S4 are good.

The specification is also requiring the fans to have a N+1 redundancy. Given the airflow and pressure for AHU-S3, a 15HP motor will not be sufficient for redundancy. See selection below:

AHUs are “fan wall” type. Redundancy is the remaining operating fan(s).

AHU-4

SF total sp is 9.5” RF total sp is 3.0”

2. Can you confirm if VIFB are required for both units? Looks like AHU-S4 only has regular heating coils.

Also, for AHU-S3, please confirm it would be acceptable to use only 1 VIFB coil (as shown on the specification layout).

Clarification:

AC-S3

· (2) CW coils

· (1) IFB heating coil

· (2) Heat recovery coils

AC-S4

· (1) CW coil

· (2) Heating coils

· (1) Heat recovery coil
