THE CHALLENGE
Conduct a façade due diligence review of the three joined four-story buildings.
CBI’S SOLUTION
The study found deteriorated mortar joints and oxidized structural steel causing lateral masonry displacement above windows which contributed to the interior water leaks. Our study resulted in the preparation of contract documents for the exterior masonry restoration, which consisted of masonry pointing, and brick replacement. Window lintel replacement was also performed. The window lintel replacement repairs included the installation of replacement steel lintels and new lintel flashing, which was not part of the original construction. Deteriorated stone bandings were replicated with precast concrete stones. Missing decorative stone elements of the façade that were removed due to extensive distress were fabricated and installed onto the building to achieve the original decorative design.
CBI was also engaged to provide structural engineering services of three existing roof top elevator machine rooms, planned for enlargement due to current code. Our review deemed the existing roof framing was deficient. CBI provided a design which utilized the existing elevator shaft construction to cantilevers to accommodate the room enlargement.
