TBTA Installation of Fender Protection

Bronx-Whitestone and Throgs Neck Bridges, NY

This project involved providing cost estimating services at the 30% Conceptual Design phase of development. Our cost estimate provided ROM comparative cost evaluation of five fender protective options at the Bronx-Whitestone Bridge and one option at the Throgs Neck Bridge. At the Bronx- Whitestone Bridge these options included Cofferdam Option, Pile Supported Dolphin Option, Sheet Pile Dolphin Option, Rock Island Option, and Sacrificial Bollard Pile Option. At the Throgs Neck Bridge we estimated the cost of the removal of the existing fender system and its replacement with the Concrete Strut and Perimeter Pile Cap fender system.
