Transforming, Inspiring and Enriching; Manhattan Bridge

IEI partnered with Skanska to provide construction support services as a structural design consultant. Skanska, one of the leading construction and development companies in the United States, was awarded a $76M contract with the New York City Department of Transportation (NYCDOT) to rehabilitate the iconic Manhattan Bridge. IEI is responsible for two designs: 1). The design of bearing stools to provide step by step procedures, repair documents, and calculations at various locations on the Manhattan Bridge and 2). The design of temporary support for the repair of a vertical gusset plate that includes design documents and calculation to support live loads from the MTA subway and Manhattan Bridge roadway. Construction is scheduled to take place after review and approval of the NYCDOT. The Manhattan Bridge that was originally built in 1909 is the most traveled bridge of the East Rivers bridges.
