Name the interface

A dependency should have a clear description, parties and required decision date.

Define ownership

Each interface needs someone responsible for driving closure.

Track assumptions

A schedule can fail when one project quietly assumes another will finish first.

Carry interfaces into handover

Temporary arrangements and shared responsibilities should not disappear when construction ends.

Scope. This page explains asset-management concepts, not operating procedures for critical infrastructure. Inspection methods, intervention thresholds and safety decisions must follow the asset owner’s standards, local rules and qualified professional judgement.
