John W. McCormack Post Office and Courthouse

ohn W. McCormack Post Office and CourthouseThe $159 million 23-story, 784,000-GSF John W. McCormack Post Office and Courthouse is a certified LEED Gold historic landmark built between 1931 and 1933 in the Boston Financial District that underwent a full-gut renovation in the mid 2000s. The construction contract, awarded by the General Services Administration (GSA) in September 2006 in the amount of $136,153,455, entailed preserving historic art-deco features while modernizing existing facilities to 21st-century standards. Upon tenant occupation of the facility in late 2009, the contractor submitted claims for delay, inefficiency, and disruption, as well as for hundreds of unresolved (denied) issues to GSA toward the end of construction. The parties were unable to reach mutual agreement; GSA asserted entitlement to recover sums for credits on allowances, deleted items, and defective work. Learn more…
