NYCDOT Bridge Design


 


HAKS provided in-depth inspection, preliminary and final design and construction support services for three bridges for the New York City Department of Transportation—the Seeley Street Bridge over Prospect Avenue, Congress Street Bridge over the Brooklyn-Queens Expressway and Lincoln Road Bridge over New York City Transit tracks, all in Brooklyn.  

The project involved MPT control plans for the reconstruction period, including manual traffic counts, automatic traffic recorder counts, capacity analysis and level of service, revised traffic signal timing for signalized intersections, and traffic user cost analysis for incentives and disincentives justification; in-depth inspection, including field survey for the superstructure and substructure; a soil investigation program and geotechnical foundation report; bridge deck evaluation report; bridge load ratings; seismic assessments; and final report recommendations for seismic and static design, including protection of adjacent structures. 

Designs were prepared for demolishing and replacing the existing superstructure; replacing back walls, bridge seats and steel pier columns; installing concrete approach slabs at both approaches; and all documentation required for the Uniform Land Use Review Procedure for legal grade changes and land acquisition. 

Highway approach work for the bridges required replacing all utilities such as drainage, electrical lines, gas lines and street lighting; subbase and asphalt wearing roadway and concrete approach slabs; and concrete sidewalks and curbs.
