The SF 1442 states the period of performance is 330 days after

NTP. However, page 4 of the “Agreement” states the contract must be complete within 210 days of NTP. Please confirm the period of performance is 330 days after NTP.

Please clarify number of volume pumps to be included in section 3.1.3.k

7/24/20

As this site is primary secondary with parallel (headered) pumps.

As the intent is a design build award:

A single new variable speed Primary pump be installed and ensure that the new pump can serve either the existing 200 ton York machine and the new chiller (redundancy)

Design team can propose variable primary flow, and add a minimum flow bypass to accomplish that approach (in-lieu of a new single pump).

SME A0001

3 7/22/20

Please specify the upgrades needed in the chiller room emergency ventilation section 3.6.1.2 This design build award must meet the ASHRAE Standard 15-2004 when completed. Field verification of existing conditions falls on the installing contractor.

SME A0001

4 7/22/20

Please clarify how many tube bundles in chiller need slow action isolation valves section 3.6

7/24/20

I believe the bullet referenced in this question is misunderstood.

The intent of this statement isn't to say there will be 4 bundles on the new chiller.

Design build contractor to deliver that all condenser/evaporator isolation valves are automated with slow-acting actuators (including the water side economizer).

SME A0001

5 7/22/20

Please confirm if the existing heat exchanger is piped in series to the chiller.

7/24/20

Existing plate heat exchanger shown on sheet M703 of 2007 Flack and

Kurtz drawing shows this clearly as a sidecar configuration, CHWR would go into the HX and back into the supply header that feeds CH-1 and CH-2.

The intent would be to either run WS economizer or mechanical cooling not a combination of the two.

The existing piping to this HX on both the condenser and chilled water piping lacks automatic isolation and will be required from the contractor.

6 7/22/20

Please provide Electrical sheet with relative location of chillers and main electrical room/main switchboard and location of main electrical room and switchboard.

Please confirm that existing Chiller VSD needs to be demolished and removed

7/24/20 Confirmed, the old chiller will be replaced with a new chiller. SME A0001

10 7/22/20

Please confirm that the BAS modifications will require new graphics

7/24/20

"Not sure what you are asking, the graphics should reflect any changes made to the physical configuration.

Editing existing graphics is an acceptable approach to match the new design build install."

SME A0001

11 7/22/20

Please confirm that a revision of the entire chiller plant sequence of operation is needed in order to provide the design intent 7/24/20 This is a design build project. The SOO is a deliverable prior to the install is performed.

SME A0001

12 7/22/20

Please advise if the chiller plant is currently being operated in auto

7/24/20 The existing chiller plant SOO is available. Upon install of this project the plant will be functional in an automatic sequence.

SME A0001

13 7/22/20

Please advise if we need to replace any sensor or device found defective

7/24/20

This question is vague.

The existing chiller that remains is under an O&M service contract to repair failed sensors/devices.

In your proposal include any exclusions to align with your design/build solution proposed.

SME A0001

14 7/22/20

Please advise if TAB on the AHUs chilled water is included

7/24/20

TAB work should be limited to flows to/from the chiller room to include both the plate HX and two chillers both condenser and chilled water flows under various modes of operation.

SME A0001

15 7/23/20

The RFP requires a turndown of 15% of its rated capacity.

Many chillers cannot meet this requirement. Is a 35% turndown acceptable? Based on the system volume this will still minimize chiller cycling and will allow more competitive options for chiller manufacturers.

7/24/20

There is a need for a chiller that can operate at low loads down to 19 tons.

Variable speed screw chillers have performance characteristics that show performance much lower than 35% turndown.
