VERTEX provided a Cause and Origin forensic investigation of a concrete masonry unit (CMU) cladding failure at a three-story residential condominium structure in Chicago, Illinois. The rear and sides of the structure were clad with CMU and the front elevation was clad with brick façade. VERTEX inspected the exterior, including from the roof, and interior of the structure and observed the CMU walls were bowing outwards and separating from the structure. VERTEX’s scope was to determine the cause and origin for the bowing and separation of the CMU walls.
VERTEX’s expertise in the structural evaluation of masonry construction allowed us to identify several deficiencies in the masonry, including evidence of historical water intrusion and heavily corroded masonry ties, which contributed to the failure of the walls. VERTEX also identified deficiencies in the construction and age-related deterioration of the roofing membrane and metal copings at parapet walls which allowed for additional water intrusion. To uncover these deficiencies, destructive removal of the interior finishes and decking on the roof were coordinated during our investigation.
