This NYCDOT project consisted of the reconstruction of seven bridges and their approaches on the Belt Parkway. All sere original structures originally built starting in 1939. The reconstruction of these bridges was accomplished by individual bridge construction contracts. Additionally, in order to mitigate wetland impacts, an offsite project at Floyd Bennett Field within the Gateway National Recreational Area (GNRA) was started in March 2011. Reconstruction of these bridges and their approach roadways was necessary to eliminate substandard conditions and bring them into compliance with current state and federal standards. These standards required wider lanes, safety shoulders, median barriers, super-elevation of the roadway around curves and realignment of the roadways in order to improve sight distances.

Hirani provided land surveying services to perform spot checks for accuracy, survey and stakeout performed by the construction contractor, check the construction contractor’s layout for correctness including line and grade, check layout of conduits, pipes, gas mains, water mains. Bridges included:

• Paerdegat Basin Bridge
• Gerritsen Inlet Bridge
• Rockaway Parkway Bridge
