Which interfaces should be recorded?
Use the tender systems and parties as the starting point. Record interfaces between electrical, civil, mechanical, controls, suppliers, the client and commissioning team where the documents identify them.
| Interface | Question | Closure evidence |
|---|---|---|
| Power to controls | Who supplies the points list? | Approved I/O schedule |
| Equipment to room | Who coordinates the outline? | Reviewed arrangement |
| Install to test | Who prepares the test record? | Approved procedure |
| Construction to owner | Who assembles handover? | Evidence index |
How should an unclear interface be handled?
Record both documents, the unanswered question, interim action and owner. An interface stays open until the responsible team approves the boundary.
- Name both parties
- Cite the source documents
- State the handover
- Assign an owner
- Define closure evidence
Why does the register matter to pricing?
A boundary can change quantity, programme, testing, labour and risk. Keeping it visible helps the estimate and response team update the bid when clarification arrives.
Common questions
What else should the bid team know?
What should a interface register record?
It should record the two parties, boundary, source, action, owner, due date and evidence needed to close the issue.
Who reviews a interface register?
The bid manager controls the register, while the affected technical and commercial leads approve their responsibilities.
Can this page replace the tender instructions?
No. The issued tender, its addenda and the responsible technical, commercial or legal reviewers control the final position.
