A two story, cast-in-place post-tensioned parking garage cut into the side of a slope provides parking area and support for a major grocery store. The second floor of the parking garage is leveled with the surface parking area adjacent to and in front of the grocery store. Issues with water intrusion, cracking, foundation performance, movement of the retaining wing wall, loss of subgrade support, jointing, construction practices, moisture management, and performance of the post-tensioned beams were investigated to determine any possible impacts on the long term performance of the structure. CA performed, among other things, a detailed condition assessment of the structure, review of construction related documents, drawings and plans, and a structural evaluation of the post-tensioned structure. CA successfully determined the causes of the concerns and developed recommendations for repair and remediating the structure to restore its performance.
