Architectural Columns Incorporated into Precast Concrete Wall Panels

The slab-edge/column-face location should be clearly defined on the Contract Documents. A 1-inch dimension is required between the edge of slab or column face and the back of the SlenderWall steel-stud back-up frame to account for tolerances both in the slab and column as well as the precast. Particular attention must be paid to slab-edge/column-face conditions along skewed or curved building edges as these areas are often the areas that cause the most difficulty during layout.
