In brief
- A trade skill check is a physical test of the person who will do the work, not a review of a certificate or a CV.
- Supervision gaps appear when no one watches the first repeat of a critical task, so the same mistake runs through the whole batch.
- Write the test, the sample and the result into the site file so the next supervisor can see what was actually checked.

A trade skill check asks the mason, steel fixer or pipe joiner to repeat one critical task while someone qualified stands next to them and measures the result. The check fails whenever the person signing off the work never watches the person doing it. Without that step, a contractor's claim of experience stays unverified, and the first evidence of weak ability arrives as a defect. Trade skill checks supervision gaps Qardho projects carry start with one question: who watched the work?
Why does an unchecked claim pass as competence?
A claim passes when the paperwork looks complete and nobody tests it. A firm lists similar jobs, a CV lists years, and the bid is signed. None of that shows whether the gang on this plot can set a level line, space stirrups or cut a thread that holds pressure. When a supervisor is shared across several sites, the check is the first thing dropped, because it costs time and produces an uncomfortable answer.
The gap widens on fast programmes. If the first ten metres of blockwork go up unchecked, the same habit carries into the rest of the wall, and correcting it later means demolition rather than a five minute reset. Ask the municipal engineer's office what inspection stages it expects to see on a plot in Qardho, and put those stages in the programme before work starts. Confirm the project specification with the design engineer for what counts as acceptable in each trade. Then ask the contractor to name the person who will do the check and the person who will do the work, and write both names down.
Where do trade skill checks supervision gaps show first?
They show first at the setting out mark and at the first repeat of a repeated task. Setting out exposes whether the crew can read a dimension and transfer a line. The first column, the first wall lift, the first joint or the first concrete pour exposes the rest. A supervisor who watches only the finished element sees a surface, not the method, and method is where ability sits.
Missed inspections cluster around hidden work: reinforcement before the pour, compaction before the slab, bedding and jointing before backfill. Once covered, the only test left is a destructive one. General practice is to hold a check before cover, with the reinforcement, the pipe or the subgrade exposed and measured against the drawing. Confirm hold points with the engineer and the client's representative rather than assuming a schedule. Ask the contractor or the client's representative for the inspection records on your own project, and check who inspected each hold point, when, and what was written down.
How do you close the gap on the next package?
Close it by writing the check into the contract and the site file. Name the task to be tested, the tolerance to be met, the person who tests it and the record that proves it happened. A short method statement with a sketch of the joint or the spacing, signed by the foreman, gives the checker something to measure against.
Request test records for anything the contractor claims was done elsewhere. For concrete, that means cube or core results; for pipework, a pressure test record; for compaction, a density result from a laboratory. Where a laboratory is used, ask it directly for its rate and its turnaround so the programme reflects reality. If a trade has no test, set one: a sample panel, a trial joint or a trial length built off the main works and inspected before the gang starts. Keep the accepted sample on site as the reference. Check what the contract allows before you link payment to any test result.
What to do next
Pick the next hold point on the programme, before concrete, backfill or plaster, and write a one page check sheet for it: task, tolerance, checker's name, result and date. Send it to the contractor and the client's representative, and confirm the acceptance tolerance with the design engineer. Then stand at the workface while the first repeat is done and sign the sheet yourself.
Frequently asked questions
What is a trade skill check on a construction site?
It is a physical test of the person who will do the work. The checker asks the mason, fixer or joiner to repeat one critical task while they watch and measure the result against the drawing tolerance.
Who should carry out trade skill checks in Qardho?
The named site supervisor or a person the client appoints who is competent in that trade. Confirm the inspection stages with the municipal engineer's office and the design engineer before work starts.
What records should a skill check leave behind?
A dated sheet with the task, the tolerance, the checker's name, the result and any sample kept on site. Add laboratory results where a test exists, such as cube results or a pressure test record.
