Brooklyn Bridge

Description

Spanning the East River and connecting Brooklyn to Manhattan, the Brooklyn Bridge serves approximately 145,000 vehicles per day. After a state inspection of Brooklyn Bridge in 2007, its condition was rated as ‘poor’. The inspection revealed that some bridge elements, including ramps, approaches, and decking were in poor condition and the structure was in need of a substantial overhaul. The 34 million dollar ramp rehabilitation of Brooklyn Bridge was part of Mayor Bill Deblasio’s Capital commitment plan. This critical rehabilitation project drastically improved the long-term functionality and public safety of this historic bridge.

Scope

The rehabilitation project consisted of a bridge deck replacement, repainting of steel elements, increasing the number of ramp lanes, seismic retrofitting of the Franklin Square Arch, and replacement of corroded railings and safety barriers. AEIS performed critical welding, non-destructive testing (NDT), bolting, and coating inspections. Our team ensured that project specifications, codes, and quality standards were met by identifying non-conformances in project materials and activities. AEIS increased project-owner confidence through collaboration with project teams on day-to-day inspection and testing activities.
