Load bearing panels will require more steel reinforcement. This will affect the thickness of panels and possibly the placement of openings. It is good to discuss minimum leg widths surrounding panel openings with the structural engineer early in the design process. The panel height needs to take into consideration the challenge of placing tall slender panels without cracking them. Generally, the taller the panel, the thicker it should be.
Strengthened backs can minimize the potential for damaged panels.
Limiting the number of different panel types improves efficiency and also eases coordination efforts. It is sometimes advantageous to create panels that are L-shaped in plan when one of the leg lengths is quite small. The placement of casting beds is important. This requires prior installation of underground utilities. A continuous leave-out at the perimeter of the building allows for construction tolerances during the erection of the panels.
