Wiley and Corbett designed the new 17-story Art Deco-influenced Criminal Courts and Prison, located at 100 Centre Street, in 1939. SHCA was commissioned to restore the facility, famously known as "The Tombs."
Designers conducted an exterior evaluation of the building façade with binoculars, followed by a close inspection from scaffolding of one bay. Damage and deterioration were recorded and served as the basis for an extensive probe investigation and repair documents.
The limestone and granite façade suffered from deferred maintenance. Breaches in the building envelope lead to serious water infiltration. This resulted in corrosion of stone anchors causing conspicuous cracks and spalls and displaced units primarily at the parapet levels.
Constituting the first phase of the project a comprehensive probe investigation removed stone units, weighing as much as 2,000 pounds (900 kg) so the underlying conditions at each of seven parapets could be examined.
The observed evidence of distress served as the basis for preparation of prescriptive construction documents. Executed in three phases while this high security jail and courts facility was occupied, the recently completed work has returned the building to a safe and dignified condition.
