01 / REVIEW

List every penetration

Assign each service or bracket an identifier and a location. Include late additions such as signage and lighting. Grouping all penetrations under a single generic note can hide different substrates and exposure conditions.

02 / REVIEW

Record the complete connection

List the penetrating item, cladding, backing and affected control layers. Request the support and weather-management detail from the responsible designer. Do not assume the cladding itself is an adequate load path.

03 / REVIEW

Control later changes

Keep an as-built record and a process for future additions. A field-drilled opening should trigger a review of the applicable detail and record, not merely an update to the finish schedule.

A junction coordination study

Concept example: a sign is added after cladding approval. Its support and wall penetration become a new interface record, rather than being treated as a decorative attachment.

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.
