CHICAGO, IL – Work continues behind the scenes at the Shrine! Simpson Gumpertz & Heger (SGH) has provided Truss Lift Diagrams. These are diagrams of the trusses and show the pick points for the crane lift. This becomes part of a written procedure for the replacement of the trusses. The complexity of this process is great, and the procedure will help define the process. Wiss, Janney, Elstner Associates (WJE) will provide a review of the process. In the design process, these drawings are called shop drawings and are reviewed by the engineer of record. It is similar to “measure twice, cut once”.
