Summarize the project's program, features and achievements?

A two-level industrial building with 36 ft. clear headroom for the ground floor warehouse and a 22 ft. clear headroom for the upper-level warehouses. Truck access to the two warehouses on the upper level was provided via a structural steel / concrete framed ramp supported on perimeter tilt-up panels.

What obstacles were overcome related to the schedule, budget, program, specification, site, etc. on this project?

Poor soil conditions required that the building foundations and ground floor slab be supported on piles. As a result, the tilt-up panels had to be erected from the exterior of the building since the loads from the panel erection crane exceeded the loads for which the piled floor slab was designed for. In addition, close coordination was required between the EOR, the GC, the Tilt-up Subcontractor, and the Structural Steel Subcontractor to plan the Tilt-up Panel erection sequence and brace removal.

Please communicate any engineering complexities or unique features of the panel design for this project?

Large window openings in the two-story tilt-up panels required that they be designed as “frames” for resisting lateral seismic loads. This resulted in heavily reinforced panels and a heavy concentration of panel to panel and panel to slab / foundation connections.
