When you need it
Use when two systems, packages or organizations must agree a specific physical or functional boundary. Prepare during coordination and revisit after changes affect geometry, loads, utilities, controls or operating dependencies.

What it helps you decide
The record places both sides of an interface in one traceable technical discussion. It exposes mismatched assumptions and verification gaps before installation or testing depends on an agreement that has not actually been reached.
How to complete it
- Define Interface identity and parties using the boundary drawing and responsible organizations. Describe Boundary and operating context, including shared utilities, dependencies and explicit exclusions.
- Compare both sides in Interface requirements using evidenced dimensions, loads, capacities or functions. In Verification and dependencies, distinguish document review, physical measurement and functional testing.
- Link Changes and outstanding decisions to the existing change register. Record Interface agreement and release with actual representatives and conditions, including any verification that must be repeated.
Who prepares and reviews it
The interface coordinator prepares it with responsible engineers from both sides and relevant operations contributors. Competent discipline reviewers check evidence; authorized representatives agree the configuration, while energization or operation requires its separate authority.
A mistake to avoid
Closing an interface because drawings align geometrically can miss functional requirements or shared-service dependencies that become visible only during coordinated verification of both systems.
Illustrative example
Illustrative example: a packaged cooling unit connects to building pipework, power and controls supplied by different contractors. The record compares each boundary requirement and identifies an unresolved control response. Both engineering teams agree the required resolution and verification before the project makes a separate operational release decision.
