Roosevelt Avenue Bridge in New York City.
Transportation has been retained by NYCDOT to provide Resident Engineering Inspection (REI) services for the rehabilitation work on the 85-year old two level, dual-use steel viaduct. The scope includes the lower level bridge deck and sidewalk replacement along with new deck drainage, expansion joints and barriers. The deck supporting rehabilitation work includes new stringers, bearings, and floorbeam repairs. The floorbeams and other remaining steel elements will include abrasive blast cleaning for removal of lead paint application of a new three coat paint system.
All work will be performed in three construction stages in order to allow pedestrian and vehicle access along Roosevelt Avenue with minimal impact to subway operations. The project is currently in its first stage beginning on the north side of the bridge.
The new deck is a concrete-filled grid deck system. A portion of the bridge structure spans the Van Wyck Expressway requiring work during off peak hours including during the nighttime hours. The deck will be installed in stages requiring splicing of the panels in accordance with the MPT plan.
The project also includes removal of abandoned control houses used to operate the movable bascule span which is no longer in operation. The Flushing River flows in an area of known contamination. The River is also tidal and is within the jurisdiction of the US Coast Guard. In addition, the presence of asbestos is expected within the control houses. Our engineers are reviewing the demolition plans for review that ensure the protection of the waterway and the health and safety of the public traveling nearby the demolition activities. Also, our engineers performed a constructability review of the contract prior to the bidding of the project. The low bidder holds property rights adjacent to the structure and was able to provide a cost considerably below the engineer’s estimate to the satisfaction of the DOT.
