MTA Construction & Development BW-96/VN-12 Design-Build Services

The major elements of the work under this project are as follows:

At Bronx-Whitestone Bridge:

1) Install a second 5KV feeder from the Queens Meter Room to the Bronx Service Building (BSB) as well as upgrade the existing substations at the anchorages and add an additional substation at the BSB for the new 5KV feeder.

2) Install a new emergency generator to give the facility a reliable and redundant power system.

3) Replace and downsize the boiler system at the BSB.

4) Replace and add to the HVAC/HV system as well as the replacement of the oil water separator and the sewage ejector pump.

5) Additional improvements include roof replacement, additions of railing along the roof line as well as interior and exterior door replacement and masonry repairs. Add parking lot lighting and conduit infrastructure to EV charging station demarcation points. In addition, aesthetically appropriate screening is required on the roof to conceal the HVAC/HV as well as along the elevated platform which will support the generator and substation building.

6) Incorporate flood protection around the perimeter of the BSB as well as along Pier 14B at the Bronx Lower Garage (BLG). This work will also include the incorporation of MTA staff deployable barriers at the openings in the wall and aesthetically appropriate treatment of the wall around the BSB.

7) Replace the SCADA system and its associated switches and integrate the required components of the upgraded electrical system into it.

8) Install a conduit system, innerducts, and fiber for FDNY from the demarcation point on a wood pole by 3rd Avenue in Queens across the BWB span to a manhole in the roadway adjacent to the BLG in the Bronx.

At Verrazzano Narrows Bridge:

1) Upgrade and recondition/refurbish the existing substations at the two anchorages as well as the Staten Island Service Building. This includes replacement of the 480V Main -Tie-Main breakers, 5KV breakers, refurbishment of the 5KV switches, replacement of the 480V switchboard distribution, transformer temperature monitors, and substation power monitoring equipment.

2) Replace the SCADA and power monitoring systems and their associated switches and integrate the required components of the upgraded electrical system into it.

3) Replace the existing Lane Control Signals (LCS) with Daktronics VMS modules and controllers. Provide communications and power to the locations as necessary including the installation of Cisco switches.
