Project Title

Owner: New York City Department of Sanitation

Trevcon and Skanska Civil, NE formed a joint venture to construct a Marine Transfer station located in the East River off the upper East Side of Manhattan.

The $181 million project consisted of the demolition of the existing transfer station, including its entrance ramp, and the construction of a new 10-story structure in its place with an expanded ramp crossing FDR Drive. 

Trevon’s portion of the work entailed construction of the marine foundations for the structure, ramp, and precast pier. Trevon built the foundations by drilling and installing 172 steel pile casings of various diameters across a 300 ft by 350 ft area in the East River subject to high currents. The deck was constructed by setting precast caps over shafts, inserting beams between the caps, then placing planks over them, and finally pouring an 8-inch topping slab over the planks.
