CA’s consulting engineering services were retained by a central Texas contractor to assess the structural damage to two double-tee precast concrete beams in a parking garage caused during the renovation of a maintenance room. As part of a renovation project, cast-in-place concrete machine pads were being removed using handheld chipping hammers when a penetration was made through the flanges of two adjacent double-tee beams. CA’s investigation included a site condition survey, measurements, photographic documentation, and a structural analysis of the as-built system to determine the extent of any reduction in the structural performance, safety, and load carrying capacity of the damaged structure. CA was able to provide the contractor with a repair procedure that was implemented concurrently during other operations, thus not delaying the overall renovation project.
