ADDENDUM NO. 1

Drawings and Project Specification Manual for the above referenced project are hereby revised in accordance with the items set forth herein. This Addendum supersedes and supplements all portions of the Bidding Documents with which it conflicts.

Changes to the Drawings Sheet E2:

1. Plan Note #4: The existing empty 4” conduits for boiler plant feeders terminate adjacent to the north side of Switch S10-1 shown on this drawing rather than beneath the switches as shown. Intercept one of these conduits and extend to beneath existing Switch S56-2, intercept the second conduit and extend to Switch S10- 1 as necessary.

2. Detail #1: A chiller has been added to Building 13, and connected to spare output on Switch S56-2. The chiller electrical feeder routes through the existing 25 KV handhole adjacent to switch S10-1, and north towards Building 13. The contractor shall disconnect the chiller feeder from Switch S56-2, and intercept prior to entering the vault, and reroute and reconnect to Switch S10-1. See revised drawings included with this addendum for wiring and conduit sizes of the existing Building 13 chiller. Provide a temporary generator and associated connections to power the Building #13 chiller for duration of downtime associated with revising the Building #13 chiller connections.

Sheet E4:

1. Revise all Type B1 fixtures shown on this sheet to Type A2, see luminaire schedule for requirements.

Sheet E10

1. Detail 2 Building 10 Electrical One-Line Diagram:

a. Replace the existing detail in its entirety with the attached detail. Add 800A/3P LSI breaker with kirk key control, install downstream of the transfer switch at each end of the switchgear. Revise the service entrance breakers to standard LSI 800A/3P breakers in lieu of draw out LSIG breakers.

Provide identical 800A/3P breakers for service entrance and kirk key controlled breakers equal to Square D NW Series.

b. Clarification: SWBD-10 shall utilize copper or aluminum bussing connected within the equipment lineup, in lieu of separate equipment cabinets connected with field wiring and conduit. Provide an open frame transfer switch for installation into the custom cabinet to allow the hard - bussed connections to be made at the factory. Switchgear shall be equal to American Midwest Power.

2. Detail 3: 25 KV One Line Diagram - Revised: Replace the existing detail in its entirety with the attached detail to accommodate the existing Building #13 Chiller 25KV connections.

3. Detail 4: 25 KV One Line Diagram – Existing: Include the attached detail indicating the existing 25KV electrical system, including the revisions required for the Building #13 chiller connections.

4. Detail 5: 25KV Underground Conduit Concrete Protection Detail: Include the attached detail for reference of typical existing buried 25KV installations, and requirements for extensions to the existing 25KV installation.

Sheet E12–Electrical Details

1. Detail 3: Switchboard SWBD-10 Elevation: Add additional sections and revise section dimensions per manufacturers requirements to accommodate equipment and circuit breaker revisions in this addendum. The maximum overall width of the equipment lineup shall fit on the east wall of Electrical Room 102, approximate width of 22’.
