Description of Modification/Amendment:

See attachment:

Amendment 0002 To Solicitation No. GS-01P-12-BZ-C-0005

Amendment 0002: The Solicitation, Montpelier Cooling Towers Replacement

Solicitation GS-01P-12-BZ-C-0005 is hereby amended as follows:

l.G Receipts of Bids: Bid due date is extended as follows:

Change From: 17 January 2012, Time 2:00 pm

Change To: 18 January 2012, Time: 2:00 pm

The below questions are answered and provided for Clarification:

1. Question: On Electrical Drawing E2.00 CWP1 and CWP2 are slated for replacement. There is no electrical notation re: these pumps. Is it simply a disconnect / reconnect using existing equipment (starters/disconnect)? Or is there to be new equipment and/or circuits provided for the new pumps?

1. RDK Response: As seen on E2.00 100% Final Working Drawings CWP-1 & CWP-2 are to be replaced with new. E7.00 Mechanical Equipment Schedule shows that there is to be new equipment, new disconnect and new feed fed from the existing breaker serving the equipment being removed in existing MCC. Per note 13 on E7.00 Mechanical Equipment Schedule “Existing starter is to remain. Replace the motor overload heaters to match new motor nameplate.”

2. Question: There is no spec for the VFD. Circuit conductor sizing and Overcurrent Protection per NEC must be sized per input values of VFD. Is there a spec for VFD? Is VFD contained as part of cooling tower equipment? Can VFD be provided separately by electrical contractor along with VFD commissioning?

2. RDK Response: 100% Final Working Drawing spec section 260000 (page 30) 3.08(A)(B) covers the new VSD and states shall be furnished by the HVAC contractor and wired by the electrical contractor. Also, As seen on E9.00 100% Final Working Drawings there is a VSD wiring detail with the note that the VSD is furnished and installed by the HVAC contractor and wired by the electrical contractor. Refer to specification section 230000 2.15 (pages 67-71) Variable Speed Drives for more information.

3. Question:The control system shall be a standalone DDC system capable of connecting to a future BAS system, however specification 230000 section 2.16, C makes reference to the control system consisting of “Network Controllers, Routers, Workstations, Software” etc, none of which would be required to provide a standalone DDC system capable of connection to a future BAS as System?

3. RDK Response: These components that are indicated will be part of the future Building Management System. The Controls installed for the cooling tower must be Bac-Net or Lon compatible for connection to these devices in the future.
