B & H Engineering is furnishing construction inspection services to the New York City Department of Transportation for the rehabilitation of the Fourth Avenue Bridge over NYCTA @ 38th Street in Brooklyn, New York. The superstructure consists of steel stringers, two concrete sidewalks, concrete deck carrying 4th Avenue, and a concrete raised island between the north and south-bound 4th Avenue traffic. This bridge crosses two NYCTA freight tracks servicing the Sunset Park Industrial Park. Located under the bridge and running along 4th Avenue are the NYCTA subway tracks for the Sea Beach Line and the Broadway - 4th Avenue Line.
The construction inspection services consist of providing field inspections; monitoring maintenance and protection of traffic, and safety; coordination with NYCDOT agencies, other contractors and utilities; reviewing contractor's schedule, equipment and staffing; monitoring contractor's EEO requirements; conducting wage rate interviews; processing payments and change orders; and maintaining office records.
The project involves the replacement of a six-lane bridge which crosses NYCTA tracks. The work includes: demolition and removal of concrete deck and steel structure, repairs to abutments, reconstruction of abutment bridge seats and roadway approaches, new structural steel, concrete overlay, deck, parapets, and sidewalks, modifications to existing drainage structures, new lighting, signals, and sign structures, installation of new water and gas mains and telephone and power conduit banks on the bridge, staged construction and MPT on bridge and local streets.
