Tilt-up construction is an economically efficient way of casting wall panels with the connectors. First the exterior layer of concrete is poured and leveled. Then the pre-fabricated, pre-drilled insulation sheets are arranged on top of the unhardened concrete according to the individual panel drawings. The connectors are inserted through the predrilled holes. After placing lifting devices, bracing inserts and required reinforcement, the structural wythe is poured. This construction is used for all types of buildings including warehouse & distribution facilities, office complexes, manufacturing facilities, schools, and correctional facilities.
