What installation tolerance and engineering detailing files are required for precision curtain wall façade construction?

Accurate tolerance and detail documentation avoids field rework and performance loss. Required items: (a) Dimensional tolerance tables for panels, mullions, and anchor grids including allowable cumulative tolerances and flatness limits; (b) Shop drawings with as-built coordination marks, panel registration numbers, and sequence of erection; (c) Interface details to structural slab edges, including slab tolerance mitigation, shim strategies, and grout/backing requirements; (d) Sealant joint design with movement capability, backing rod sizes, and adhesion primers; (e) Control joint and expansion joint layouts and recommended cover plate/flashings; (f) Tolerance adjustment procedures for out-of-plumb conditions and recommended corrective actions; (g) QA inspection checklists for dimensional checks during erection (coordinates, datum verification); (h) Tolerancing rationale and representative mock-up acceptance criteria. Include annotated PDFs and CAD/CAM files for fabrication so contractors can pre-verify fit prior to installation.
