PROJECTS

Description:

This project involved the rehabilitation of 10 pump rooms along the Queens Boulevard Line. The work included excavation and installation of new discharge lines running from the pump rooms to a newly installed pressure relief manhole. A new connection was made from the manhole into an existing sewer so that the discharged water could drain into the sewer. In some instances a concrete shaft was installed to allow for the delivery of materials from the street level to the pump room at the subway level.

Scope of Work included:

• Demolished/replaced floors, electrical panels, pumps and mechanical piping.
• New asphalt and sidewalks at all locations.
• Electrical feeds were run from the distribution rooms to the pump rooms.
• Mounted and connected new electrical panels.
• New instrumentation and control equipment.

Electrical feeds were run from the electrical distribution room to the pump room and new electrical panels were mounted and connected inside the room. Instrumentation and control equipment was installed, which detected the water level in the sump and turned on the pumps when needed. New doors and alarms were also installed.

During the project, Judlau was also required to complete flood mitigation work for New York City Transit. Judlau installed over 790 raised modules throughout the city. These new stainless steel modules anchor to angled frames that are imbedded into a concrete slab below the sidewalk. They extend up out of the sidewalk with the perimeter sealed tight with the sidewalk to increase the height that the water level needs to reach get inside the vent. This raised module will still allow for air to flow in and out of the vents while reducing the potential risk of flooding.
