United Nations Master Plan & Infrastructure Upgrades
LERA provided structural engineering services for a series of capital improvements to the United Nations, the first to be performed since the complex was built in 1952. Initial work included the seismic evaluation of the UN building structures in accordance with the New York City Building Code seismic provisions; evaluation of current repair programs; and concept designs for the expansion of the conference building and meeting facilities, as well as the consolidation of technology areas on campus into a new, Tier 3+ main data center.
The second phase of work consisted of significant infrastructure upgrades to further modernize the complex, such as the addition of four sets of 2MW gensets and switchgears to provide power to the UN campus, as well as two cooling towers with a 2,000-ton output. LERA reviewed the effect of the added weight on the existing structure and designed exterior steel dunnage to accommodate it.
