VN-35, Design and Construction Support Services of Miscellaneous Structural Repairs, Verrazano Narrows Bridge
The Verrazano Narrows Bridge is a heavily traveled, 9,800-foot-long, suspended span bridge, connecting Brooklyn and Staten Island. Existing construction varies, and consists of a 4,260-foot main span, 1,215-foot side spans and approach spans on both sides.
The scope of the work included design and Construction Support Services for miscellaneous structural repairs for twelve (12) approach spans. As part of the design process, we performed inspection of the approach spans which included concrete piers, steel floorbeams, steel stringers, rocker bearings, underdeck and joints. We designed bearing replacements, steel repairs and concrete repairs to all bridge elements. Jacking loads were calculated for bearing replacement and jacking schemes were developed for the project. Quantity and cost estimates were prepared for the project.
SEPC also provided construction support services which included approving shop drawings, jacking schemes, concrete mixes, etc.
