01 / REVIEW

Split the perimeter into records

Give the sill, jamb and head individual references. At the lower corner, note where their functions meet. Avoid signing off the entire perimeter when only one segment has a documented response.

02 / REVIEW

Track the actual products

Record window system, cladding profile, trim, membranes and sealants as separate items. For each connection, request the applicable manufacturer information and design response. A generic material name is not a compatibility statement.

03 / REVIEW

Review the corner sequence

Ask which component is installed first and what evidence will remain visible. If a corner detail is revised, check both adjoining records rather than changing a dimension in one view only.

A junction coordination study

Concept example: the jamb reveal changes during coordination. The sill end condition must be checked again because the revised trim no longer aligns with the previously reviewed corner.

Use the result

Keep the completed review with the relevant project record. Assign unresolved items before relying on a conclusion. If the material, condition or document changes, revisit the affected questions.
