Physical Properties

Optimizing the precast system includes reducing the production cost and increasing the speed of erection. The examples shown in drawing details P-1 through P-4 in the Typical Details illustrate several different ways panels can be combined or split up to achieve a desired result. Depending on panel sizes, shipping limitations, erection considerations and/or connection concepts, any one of these solutions may be the one best suited for your particular project. As shown in drawing details P-2 and P-3 in the Typical Details, it is desirable to maintain a minimum section of 18-inches concrete around all openings and block-outs. Also, rough-opening-window-widths should be limited to 7-feet-0-inches unless special designs are implemented. Consult your Easi-Set sales or technical representative for assistance in providing optimal panelization options for your particular project.

In general, the economics of the design are driven by two key factors:

  1. Size of panel
  2. Form utilization (repetition of same form)

Precast Wall SystemsBecause erection cost is typically considered on a fixed “per piece basis,” it is generally advantageous to find ways to reduce the number of erected pieces by making panels as large as possible. Note, however, that panel size is often constrained by fabrication and shipping considerations. Panel sizes can also be affected by the hauling conditions particular to the project in question and/or site conditions that may result in weight or crane reach limitations. Site access must also be considered when determining maximum panel sizes. Generally, the maximum economical size to produce is 10-feet by 35-feet. The largest panel size that can be produced is 13-feet by 40-feet, but there could be significant additional shipping costs to consider.

The second consideration in panelizing the building is form utilization, or the number of form set-ups. The more times the same form can be used, the lower the fabrication cost per piece will be. Therefore, it is extremely useful to look for ways to make maximum use of the same forms by building repetition into the shapes and sizes. This is especially important for buildings with brick finishes. Drawing Details A-9 and A-10 contained in SECTION 3.01 of this Technical Design Guide show guidelines for laying out brick patterns that reduce cost.
