In brief
- A reference letter or certificate shows a person was on a project, not that they can repeat the work to specification.
- Ask for method statements, test records and the name of the person who supervised the work, not the project owner.
- Set a paid trial section with a hold point before awarding the full package.

A reference letter or training certificate only shows that someone attended a project or a course. It does not show that they can repeat the work to the specification on your site. Project references training gaps in Hargeisa sit in that space: the paper can be genuine and still tell you nothing about method, records or supervision, so the check has to move past paper and into a supervised trial.
Why does a reference letter not prove competency?
A letter confirms presence and dates, and sometimes nothing more. Attendance at a training course records hours in a room. Presence on a completed project records that a name appeared on a payroll or a list submitted at handover. Neither records what the person actually did, under whose instruction, or whether the work passed inspection.
The gap widens when the referee is the project owner rather than the trade supervisor. An owner signs what the main contractor puts in front of them. The person who watched the work daily, checked setting out, rejected a bad batch or signed a test request, is the one who knows whether the crew can hold a line, cure concrete or lay blocks to a line and level. Paperwork of this kind does not carry method, records or supervision on its face, whatever the town.
Check what the reference actually covers before you weight it. On your own projects, look at how references are issued and what a one-page letter omits; that tells you how much to rely on the document in front of you. Ask the municipal engineer's office what records exist for the project named.
What should you ask for instead of a certificate?
Ask for the documents that the work itself generated. A method statement the applicant wrote or used, a concrete cube or slump record, a setting out sheet, a waterproofing or pipe pressure test record, a snag list they closed. These show how the person works, not just where they were.
Then run a short interview on the method. Give a plain task from your own project and ask for the sequence, the hold points and the checks. For blockwork, ask how the first course is set and how verticality is checked. For a slab, ask when formwork comes off and who confirms it. For buried pipe, ask how joints are tested before backfill. Vague answers expose gaps quickly.
Where trade certification is claimed, ask the training provider what practical assessment the learner passed and who signed it off. A certificate is only as strong as the assessment behind it. Where the provider is local, ask to see the assessment record, not just the attendance register.
How do you close the gap before award?
Set a paid trial section with a written hold point. Pick a small, representative piece of the package: one room of blockwork, one slab panel, one pipe run with a test. Agree the specification and the check before work starts. Supervise it, inspect it, and record the result.
The trial does three things. It shows the crew's real speed and finish. It shows whether the supervisor can read the drawing and hold the sequence. It gives you a documented result to compare against the reference.
Put the trial in the tender documents so every bidder prices the same scope. State the hold point, the inspection and the acceptance criteria in the contract, and check what your contract allows before you vary or withhold anything. If the trial passes, the full package starts with a known crew. If it fails, the reference has been tested before the main spend, not after.
Confirm all technical limits, curing times, test pressures and acceptance criteria against the project specification and the engineer's instruction. General practice varies by element and by specification.
What to do next
Pick the next package you plan to award and rewrite the reference check as three questions: who supervised the applicant, what did they personally do, and what document proves it. Send those questions to two shortlisted bidders and to the named supervisors. Then set one paid trial section with a written hold point before you sign the main award.
Frequently asked questions
Do I still need reference letters at all?
Yes, as a first filter. They confirm dates, project names and contacts. Use them to decide who to interview, then verify the claims against records and a trial section.
What if the applicant has no written records?
Ask for the supervisor's name and contact, then interview that person about the specific work. Where records do not exist, the paid trial section becomes the main evidence.
