Overview

Weidlinger Associates, which merged with Thornton Tomasetti in September 2015, was the engineer of record for a renovation of the Jacob Javits Convention Center, which was originally designed by the firm in the 1980s. We collaborated closely with the construction manager, Tishman Construction, to expedite construction logistics and effectively incorporate myriad changes to the structure, including the addition of a green roof, reconstruction of the curtain wall and entrances, and upgrades to building systems. In 2012, floodgates were introduced at three emergency exit locations along 12th Avenue.

We performed an exhaustive study of the original space-frame structure – one of the largest ever built – to verify its capacity. Our team developed a detailed computer model using ANSYS finite-element software. To expedite the process, we devised an automated method for entering and verifying data from the original, hand-drafted design documents. The study concluded that the structure could support all the planned improvements, including a 6.75-acre green roof that helped the facility obtain LEED Silver certification.

The new curtain wall dramatically changed the building’s appearance by replacing the original, dark glazing with translucent, energy-efficient glass that produces a bright, transparent effect.

Because of the effective integration of the design and construction teams, this complex project did not encounter any major problems, even while remaining open throughout construction.
