PROJECT OVERVIEW
The project was a Joint Venture with Tully Construction that consisted of replacing, in its entirety, three bridges on the Belt Parkway in eastern Brooklyn, New York. In addition to the three bridges, 2.5 miles of roadway section, including all drainage and electrical systems were replaced. The roadway was raised to provide improved sight distances across the bridges and improved storm water drainage.
WHAT MADE THIS JOB COMPLEX
This project consisted of two bridges being built over water, which made it difficult. Performing the work while maintaining six lanes of traffic resulted in very small construction work zones with very few points of access. The project was also surrounded by park and wetland properties, which required special environmental precautions.
HOW POSILLICO SOLVED IT
Posillico re-sequenced the traffic maintenance plan to utilize a temporary bridge over Fresh Creek. This enabled the Fresh Creek Bridge to be built in two stages instead of three as originally designed. This Value Engineering proposal saved the owner, NYCDOT, money in direct construction costs and enabled the Joint Venture to complete the project 14 months ahead of schedule and earn the maximum bonus from NYCDOT.
