Resident Engineering and Inspection Services for Reconstruction of 91st Place Bridge over Long Island Railroad

HAKS provided construction inspection services for work on the 91st Place Bridge for the New York City Department of Transportation. This structure spans Long Island Railroad facilities in Queens, NY. The existing three-span bridge was being removed and replaced with a modern one-span structure.

The new superstructure consisted of a concrete wearing surface cast with an open steel grid deck supported on new steel stringers. New utilities were constructed on the bridge itself and within both approaches. New approach roadways were constructed. New traffic signal and street light systems were installed. Existing catch basins were modified and new drainage pipe installed. The existing 203mm water main was upgraded to a new 305mm diameter main. New gas main, electric line, and cable facilities were installed.

Staged construction was used to minimize the impact on the community and the traveling public. Low headroom, bored-in-place mini-piles were used with new pile caps under the existing bridge. This was done before the existing bridge was disrupted.

HAKS' efforts in support of this construction consisted of managing the entire project ensuring that all work was completed in accordance with contract requirements. The contractor's progress was monitored and compared to the approved schedule. Adequacy of the MPT measures were continually reviewed. HAKS chaired monthly progress meetings and was responsible for coordinating with local agencies, public groups, and utilities. HAKS was also responsible for change orders, payments requisitions, and final project close-out.
