How do you check prop removal competence in Burao?

Prop removal training gaps in Burao show up the moment a prop comes out: attendance at a briefing does not tell you whether the person holding the hammer can judge when concrete has gained enough strength. The check is the same everywhere. Ask for the stripping plan, the test records for that pour and the name of the person who authorises removal.

What does prop removal competence actually mean?

Competence means the person can read the pour record, match it to the specified strength at stripping and refuse to remove a prop when the numbers or the conditions do not support it. That is a judgement about a specific slab or beam on a specific day, not a general skill. A training session can explain creep, deflection and the loads a prop carries, but it cannot confirm that the trainee will stand on a Burao site and say no to a supervisor who wants the props out before a floor slab is poured above.

General practice in hot, dry conditions is that concrete gains strength quickly in the first days and then more slowly, and that ambient temperature, wind and curing affect the result. The stripping age or strength given in the project specification is the figure that governs, so confirm it with the engineer rather than relying on a rule of thumb. Ask the municipal engineer's office whether it holds any record of approved stripping procedures for similar structures, and treat that as background only.

Why does attendance not prove the skill?

Attendance records measure presence, and presence is cheap to arrange. A classroom session can be counted, photographed and filed, which makes it attractive to a training provider that needs to show numbers. The person who sits through it may still have never seen a cube test result, never read a pour card and never had to decide whether a prop under a cantilever could come out.

Workplace learning barriers make this worse. On a busy site, the person who removes props is often the least experienced hand, and the decision is made by whoever is in a hurry to start the next floor. Ask a supervisor how a new worker learns the job and the honest answer is often by watching someone else do it. That is how a wrong habit spreads. When you review a contractor or a training provider, ask what practical assessment was used, who signed it off and what the candidate had to do to pass. If the answer is a written paper, the assessment does not cover the task.

How do you detect the gap before the props come out?

Walk the site and look for the record trail. Ask to see the stripping plan for the current floor, the concrete test results for the pour in question and the signed instruction that allowed earlier props to come out. If those documents do not exist, the competence question is already answered.

Then watch the mechanism. Premature structural loading happens when a slab or beam carries loads it was not designed for at that age: the next floor's formwork and wet concrete, stacked blocks, a loaded lorry, or a crowd. Ask who decides when the next lift can start and whether that person has seen the strength results. Check whether props under long spans or cantilevers stay in place longer than those under short spans, and whether the engineer's specified back-propping sequence is followed. On your own site, ask the supervisor to explain one removal decision and the evidence behind it. Vague answers tell you more than any certificate.

What to do next

Before the next pour, request the stripping plan and the test records for the slab below, then name one competent person in writing who authorises prop removal. If no test records exist for the pour, ask the laboratory for the results and hold the props until the engineer confirms the strength at stripping. Put the authorisation in the site diary each time.
