O’Donnell & Naccarato is currently providing engineering services for the façade rehabilitation of a five-building office complex. The rehabilitation program is following a comprehensive assessment of the campus facades to identify the source of water infiltration. O&N was contacted to assist our client who experienced water infiltration through isolated locations on the facade during wind-driven rain events. Phase one of the work is currently underway to address the most severe facade deficiencies that includes: brick deficiencies, inadequate flashing installations, failed sealants, and failing window gaskets. Our initial assessment consisted of a combination of up-close investigation via rope access, exploratory probes, forensic ASTM water infiltration testing, and an extensive review of the original design documents. Our report recommended reconfiguration of through-wall masonry flashing, isolated brick masonry repairs, isolated cast stone coping repairs, and 100% sealant replacement with improvements to improve inadequate joint design. Our phased repair plan includes performing the repairs while the buildings are occupied and minimizing disruption to the building occupants.
