The Hospital For Special Surgery — Addition and Alteration, New York, NY

Since its founding, the Hospital for Special Surgery has continuously sought to meet the quality healthcare needs of the metropolitan New York area. As part of its major modernization program a seven-story building was built over the FDR Drive and constructed partially from barges in the East River. The project consisted of five floors of 160 medical and surgical beds, one floor of Radiology and one floor for a 50 space parking area. Also included were major alterations of the OR Suite, Rehab, Radiology, Doctor’s Offices, an Out-Patient Clinic and Day Surgery. Each of the patient floors boasts its own 1200 square foot Atrium. Completed in record time, this addition is a good example of how innovative design coupled with precise construction coordination can result in a successful project.

The use of an innovative steel truss platform system and a complex erection scheme used barge cranes berthed along the sea wall of the East River which enabled the successful expansion of the hospital over the FDR Drive.

Review and approval of over 45 agencies was required including the NYC DOT and the U.S. Coast Guard.

The design met seismic requirements and the 19 foot deep by 96 foot span steel truss platform, was completely fabricated off site in four 4800 square foot sections weighing 800 tons each with all the mechanical elements.

The platform was barged to the site for night time erection during a seven hour window to avoid the morning rush hour. The erection process took five nights to complete.
