What is final acceptance?
The formal last step of commissioning — reviewing the evidence, closing defects and handing the system over to the owner.
Final acceptance comes after every test has been carried out. The owner or their representative reviews the test records, sees key tests demonstrated, and checks that the installed system matches the design. Open items on the punch list are closed and re-tested.
The handover pack is delivered: as-built drawings, manuals, spares and training records. Each step is recorded. If something is not accepted, it is corrected, re-tested and re-submitted. When the owner is satisfied, the certificate is signed and the system is ready for service.
- Records. Review every test record for completeness and compliance with limits.
- Witness. Demonstrate the agreed key tests to the owner.
- Punch list. Close each open item and re-test where needed.
- Handover. Deliver as-built drawings, manuals, spares and training records.
- Sign-off. Prepare and sign the acceptance certificate.
- Record. File the certificate and handover pack; correct and re-submit anything rejected.
Frequently Asked Questions
Q1What is final acceptance in airfield ground lighting?
The formal step at the end of commissioning where the owner or their representative accepts the installed system. Test records are reviewed, key tests are demonstrated, open defects are closed, handover documents are delivered and an acceptance certificate is signed.
Q2What does the owner check before accepting?
That the electrical, photometric, functional, integration, ALCMS, PAPI and sign test records are complete and within limits, that the installed system matches the design, and that no defect is left open without agreement.
Q3What is a punch list?
A list of the outstanding defects and incomplete items found during inspection and testing. Each item is closed and checked off, or formally agreed as a minor item to finish later, before the acceptance certificate is signed.
Q4What documents are handed over?
Typically as-built drawings, the test and commissioning records, operation and maintenance manuals, equipment data sheets and warranties, a spare parts list, and records of operator and maintenance training, as the contract requires.
Q5Why witness key tests during acceptance?
Seeing selected tests carried out, such as circuit operation, controls and alarms, lets the owner confirm the records reflect real performance. The set of witnessed tests is agreed in the specification or test plan.
Q6What happens if the system fails acceptance?
The failed items are recorded and corrected, the affected tests are repeated and the results re-submitted. Acceptance is signed only when the owner is satisfied, and the record keeps the failure, the correction and the passing re-test.
