In brief
- A commissioning record only has value when a named person watched the test, wrote the reading and signed the sheet on the day.
- Unsigned or undated sheets, missing instrument numbers and absent retest dates are the usual signs that supervision did not cover the test.
- Ask for the full record set before final payment, then run one witnessed retest on the system that matters most.

Commissioning records supervision gaps in Qardho show up as paperwork that describes tests nobody witnessed. A pump sheet with no instrument number, a tank test with no start time, a signature added weeks after the visit: each one means the system performance in that record is unverified. The building may still work, but the client has no evidence either way.
What does a commissioning record actually have to contain?
A usable record names the system, the test, the date, the person who watched it and the reading they saw. General practice in building services is to record the item tested, the method, the instrument and its calibration status, the measured result against the acceptance figure in the specification, the outcome, and the signature and role of the witnessing supervisor. Ask the project's engineer to confirm the format your contract requires, because acceptance criteria sit in the specification, not in a default template.
Temperature and water availability affect tests on tanks, pumps and pipework, so the record should also note the conditions on the day. Walk any recent site and ask to see one completed record set. If the sheets carry only a result and a company stamp, with no instrument and no individual name, supervision likely attended the commissioning as an observer rather than a witness.
How do gaps in site supervision failures reach the handover file?
The mechanism is simple: a test is run by the installing crew, the result is written up afterwards, and no independent person checks the reading against the instrument. Commissioning often happens at the end of a job, when the supervisor is already moving to the next site and the pressure to hand over is strongest. A sheet signed late, or signed by someone who was not on site, passes into the file and then into the client's archive. Site supervision failures rarely appear as a missing document. They appear as a document that looks complete but cannot be traced to a person, a time and a reading.
To detect this, compare dates. Line up the commissioning record dates against the site diary, the attendance sheet or the daily report. A test recorded on a day when the responsible supervisor was elsewhere is a record to question. Then pick one system and ask for the raw field notes behind the typed sheet.
How do you close the gap before final handover in Qardho?
Make the witnessing requirement explicit before the work starts, not after. The contract can require that each commissioning test is witnessed by a named supervisor, recorded on a numbered sheet, and counter-signed by the client's representative on the day. Check what your contract allows for payment against handover documents, and take advice before holding any amount back. Then verify by sample. Choose the system with the highest consequence if it fails, such as a water tank, a pump set or a generator, and ask for a witnessed retest with the instrument shown and the reading written in front of you.
For the local picture, ask the municipal engineer's office whether it holds records or requirements for building services handover in Qardho, and ask two contractors to show a complete commissioning file from a past job with names and dates intact. What they can produce tells you what to expect on your own site.
What to do next
Before the next handover meeting, request the full commissioning file and check three things: a printed name and role on every sheet, a date that matches the site diary, and an instrument number against each reading. Then book one witnessed retest on the most critical system and sign the result yourself.
Frequently asked questions
Who should witness commissioning tests on a Qardho project?
The contract should name the person, usually the supervising engineer or the client's representative, and require their printed name, role and date on each sheet. Confirm the requirement with the project engineer before tests begin.
What if the contractor cannot produce commissioning records?
Ask for the field notes, instrument details and diary entries behind the missing sheets. If none exist, request a witnessed retest of the critical systems before handover and check what your contract says about the documents required for completion.
