Sugar Hill Bridge Over Babcock Creek

Taylor Wiseman & Taylor provided complete Design and Construction Inspection services for the rehabilitation of a bridge near the intersection of NJ Route 40 and Somers Point-Mays Landing Road (CR 559) over Babcock Creek for the Atlantic County Engineering Department.

The design phase included evaluation of the existing bridge deck to determine the limits of repairs necessary to address a Priority I repair letter from NJDOT. TWT performed a non-destructive test using Ground Penetrating Radar (GPR) to scan the bridge deck and identify concrete deterioration below the bituminous overlay. A map of the deterioration was generated from the scan, revealing problem areas which were not visible on the surface. Several concrete core samples were also obtained to evaluate the compressive strength of the existing concrete in select locations, as determined by the GPR. This testing enabled TWT to recommend selected areas of the concrete bridge deck to replace, thus preserving as much of the existing concrete deck as possible and reducing construction time and cost.

Design services included detailed structure plans and repair details, construction staging with one-way detour, temporary signal re-timing for the adjacent NJ Route 40 intersection, NJDOT Highway Occupancy permits, and final construction contract documents.

Following design, TWT performed Construction Inspection and Management services. TWT was able to assess, and subsequently provide, onsite engineered solutions for unforeseen repairs to the 50-year-old superstructure, limiting our client’s time spent onsite and in meetings, and enabling the project to stay on the critical path schedule and be completed within its projected 3-month duration.
