Establish a warranty and shop-drawing review workflow for a commercial curtain wall submittal package

Steps

1. Set up the submittal review sequence per standard CSI/AIA construction documents practice: shop drawings first (fabrication/erection details, anchor conditions, expansion joints, waterproofing tie-ins), followed by product data, then samples, with warranty documentation submitted closer to substantial completion.
2. Cross-check shop drawings against the approved mock-up test report and structural calculations (deflection, anchor loads) rather than reviewing drawings and test reports in isolation, since shop drawing revisions after mock-up testing can invalidate the tested configuration.
3. Confirm warranty terms directly against the specific manufacturer's current warranty document for the exact products proposed — do not assume a standard industry warranty duration (e.g., structural sealant or insulating glass seal warranty periods vary by manufacturer and product line and should be verified per project, not assumed as a fixed industry figure).
4. Confirm whether the warranty is a manufacturer materials-only warranty, an installer labor warranty, or a combined system warranty, and identify any installer-certification prerequisites the manufacturer requires to keep the warranty valid.
5. Track submittal review comments (rejected, approved as noted, resubmit) through closeout, and confirm final as-built shop drawings and the executed warranty documents are part of the closeout package before final payment/retainage release.
6. Flag any field changes made during installation (anchor substitutions, sealant substitutions) for warranty-impact review, since unapproved field substitutions can void manufacturer warranties even if the original submittal was approved.
