GFRC facade tolerances
Tolerances should be agreed before fabrication, covering panels, subframes, supporting structure and joints.
Fabrication and erection tolerances are established in the project specifications and coordinated engineering, consistent with applicable requirements. They must account for panels, secondary framing, the supporting structure, joints and expected movement.
Site surveys and coordinated drawings help identify differences between the model and actual conditions.
Request the tolerance schedule applicable to your project. A single value should not be assumed for every size, geometry or installation system.
