Precast-concrete Erection Issue: resolved, construction proceeded

A major office construction project utilized precast concrete elements. The precast concrete erector subcontractor expressed concern for the support detail of one of the elements referred to as a "light shelf". Calculations were performed on the support detail to confirm it was structurally adequate to support the element. A load test was set up to confirm to the subcontractor that the support detail was adequate. The precast element was loaded to subject the support detail to 2.5 times the design load. The element did not fail; therefore the subcontractor commenced erection and installation of the "light shelf" facilitating the completion of the project.
