Overview

The Commonwealth Building was constructed from 1944 – 1948 and is one of the first towers to be completely clad in aluminum and to use double-glazed window panels. In addition, it is the first building to be completely sealed and fully air-conditioned. As a result of these accomplishments the building was placed on the National Register of Historic Places in 1976 and became a National Historic Mechanical Engineering Landmark in 1980.
Technical Waterproofing was hired by CBRE to perform a full façade sealant restoration along with the inspection and repair of the façade fasteners which connect the aluminum panels to the structure.
After erecting the necessary pedestrian protection and swing stage access, our craftsmen installed more than 3000 lineal feet of pre-molded silicone tape, repaired and replaced 15,000 fasteners, and installed more than 6 miles of wet seal joint installation.
