Bldg. 200 AHU and Motor Control Center Replacement

Project # 662-12-004

General Intention:

A. Contractor shall furnish all labor and materials needed to perform all demolition, renovation, replacement, installation, finishes and commissioning required by this scope located at the San Francisco Veterans Affairs Medical Center as required by specifications.

B. Visits to the site by bidders may be made only by appointment with the Contracting Officer for the project.

C. This project is to take no longer than 360 calendar days from notice to proceed. This project will be phased and temporary electrical feeds will be necessary, the contractor shall reflect this in his proposal.

D. The contractor will dispose of all equipment components demolished or replaced as part of this project.

E. Contractor shall be responsible for providing temporary electrical feeds to electrical motors as necessary for replacement of each Motor Control Center. Also the contractor will be obligated to reroute all conduit and feeds as necessary to complete the installation as shown on attached diagrams.

F. The contractor shall include all necessary name plates for each device and provide the arc flash rating for each piece of new equipment. The contractor shall show the report which includes the calculations to determine the arc flash rating for each piece of new equipment. Arc flash protection similar to the Eaton Motor Control Center models is preferred.

G. Variable Frequency Drive (VFD) Where ever referenced, assumes Toshiba Q9 or equivalent equipment to be installed.

H. Each Motor Control Centers shall have gateway monitoring system similar to the Eaton system. It shall be able to allow trending and monitoring of each device in the Motor Control Center. This system shall be networked to allow remote monitoring from the network. Each device in the Motor Control Center shall have a LCD screen to show electrical values of the device, current, volts per phase, etc.

All Motor Starts shall have LED indication lights for status: run, off, failure.

J. The contractor shall provide the adequate amount of spaces per the table per each MCC. The contractor is to provide the correct size Motor Start, VFD, or adjustable breaker as required by the table. All spaces in each Motor Control Center will be filled with one of the choices above. Adjustable breakers will be 0-100 amp adjustable trip.

K. The contractor shall be responsible for tying in all Motor Starters shown on the load schedules. All existing Motor Starts at the equipment shall be bypassed and removed from the equipment. This will insure all Motor Starters will be energized from the Motor Control Center Cabinets.

MCC-D:

Replacement of MCC-D will require a new feeder to be installed from the basement of Bldg.200, from MS-2 panel board to the penthouse location. Recently a similar electrical feed was installed from EMS-B on the exterior of the building to the penthouse, approximate linear run was 200 Feet. The VA would like a similar installation for this new feed for MCC-D. This project will include a painting of the exterior conduit with marine paint type application. This new feed will connect to the new MCC-D in its new location, see drawing A. This feed will be 600 kcmil size wires, 3 wires in the conduit. The contractor will need to install the appropriate conduit size and pull boxes required for this installation. The contractor will also provide the wire and labor necessary to install the wire rating necessary for the project. The VA is specifying Eaton Motor Control Center equipment due to its Arch Flash safety device features which will make this installation very simple. Without completing a large shutdown, the VA would like to have both MCC-D, new and old activated at the same time to allow a faster switch over of each load independently allowing only small shutdowns for each device. The contractor shall have the new MCC-D 100% installed and ready for load transfer. The contractor shall prepare and install all re-routing conduits and junction boxes before the first shutdown is scheduled. Once the entire load of MCC-D has been transferred and connected to the new MCC-D, old MCC-D shall be demolished and removed. New MCC-D has a load schedule below showing each planned transferred load and spares located which will be filled with an adjustable breaker. New MCC-D rating is minimum 400 Amps, 480/277.

MCC-E and X:

Once MCC-D has been replaced, its original location will be used for the new MCC-E and new MCC-X location. Each MCC has a load schedule below showing existing load, and spare locations which shall have an adjustable breaker installed. There are three emergency feeds that feed existing MCC-E and MCC-X, a 100 amp, 200 amp, and 400 amp feed. See one line diagrams attached to reference the feeds. When both MCC are completely installed, MCC-E will be fed by a 400 amp feed, that it is fed from now. MCC-X will have a 200 feed which exists but not yet activated. The 200 amp feed is not connected, but coiled up inside the MCC-E. The 100 amp feed will be abandoned and leads will be removed from the breaker in panel EMS-B. The 200 amp feed leads will need to be landed on an existing 200 amp breaker located in panel EMS-B. The equipment on both of these MCCs must have short shut down times either for load transfer or temporary feeds. MCC-E shall be a minimum of 400 Amp 480/277 V. MCC-X shall be a minimum rating of 200 Amps 480/277 V.

MCC-F:

MCC-F will be replaced and the new MCC-F will be placed in the same location. The existing loads on MCC-F will be temporarily fed from the new MCC-D during replacement. The existing feed for MCC-F is a bus tie off the existing MCC-D. When new MCC-F is completely installed, it will be fed from the existing feed of MCC-D, as new MCC-D will have a new feed installed during the project. MCC-F has a load schedule below, showing existing loads and spares that will be installed for the new MCC-F. MCC-F minimum rating is 400 Amps, 480/277. With the replacement of MCC-F, a new door will be cut into the existing louver section of the North side of the penthouse, near MCC-F location. This door should be 4' wide minimum, with appropriate lockset shown in specification section 010000. This will allow the contractor to access the penthouse for easier delivery of these electrical items.
