How do you review commissioning records in Bosaso?

Commissioning records experience gaps in Bosaso show up when the people reviewing the handover file have never assembled one themselves. The record set looks complete because it has sections and signatures, but nobody checks whether each test ties to a real system, a real instrument and a real date. The result is a building handed over with unverified system performance.

What does a commissioning record set actually contain?

A commissioning record set is the evidence that each installed system was tested and left working, not a folder of certificates. For a pumped water system it normally holds the pump curve, the flow and pressure readings at the duty point, the tank fill and drawdown test, the electrical insulation readings and the signed test sheet naming the instrument used. For a generator or solar set it holds load bank results, protection settings and the changeover test. Mechanical ventilation needs air flow readings at each grille. The general practice is that every reading carries the instrument serial number and calibration date, so a later reader can tell whether the number means anything. Confirm the exact schedule against the project specification and the engineer's commissioning plan, because the required tests vary with the system.

How does the experience gap put Bosaso projects at risk?

The risk comes from the reviewer, not the installer. A supervisor who has never closed out a commissioning file tends to accept a document because it is bound and signed, and to skip the cross-checks that catch a missing test. Three failures follow. First, unverified performance: the pump is assumed to meet the design duty because no one compares the recorded head and flow to the specified figures. Second, gaps between systems: the tank test exists but the level control and low-level cut-out were never proved together, so the first dry season exposes the fault. Third, late discovery: defects surface after retention is released and the contractor has demobilised. The client can reduce this by asking the reviewer to describe one commissioning file they personally closed out, and by requesting the instrument calibration certificates at the same time as the test sheets. Ask the local authority which record format it expects for its permit file, and confirm it in writing, then walk a recently handed-over building to see how its file was actually kept.

How do you check the records before you sign?

Check the records system by system, in the plant room, with the equipment running. Pick the pump, the tank and the main distribution board and ask for their test sheets. For each sheet confirm four things: the system tag matches the as-built drawing, the readings fall inside the specified range, the instrument serial and calibration date are recorded, and the person who signed was on site that day. Then repeat the reading yourself with a calibrated gauge and compare. A gap between the recorded figure and your own reading is the finding, not the paperwork. Where a test was never done, list it as an outstanding item and ask for a re-test date. Check what the contract allows you to do about retention or final payment at that point rather than deciding on the spot. If no one on the team can run this check, bring in an independent commissioning engineer for the handover week.

What to do next

List every system in the building and one test that proves it works. Send that list to the contractor and ask for the matching records with instrument serials and dates before the handover meeting. If the records cannot be produced for any item, write it into the snag list with a re-test date and check your contract terms before releasing retention.
