In brief
- Site overheads in Qardho cover the clerk of works, test records and standing plant that catch defects before they are covered up.
- A supervision gap often shows up as an empty inspection log rather than a visible building fault.
- Ask for the dated inspection record and the concrete cube results before accepting that work is complete.

Site overheads supervision gaps in Qardho start when the supervision line of a bill is trimmed to win the job. The clerk of works, the test cubes, the water bowser hours and the standing plant all live in that line. Cut it and the checks that catch bad work stop before the bad work does. The defect then waits under the screed or the backfill until someone else finds it.
What do site overheads actually pay for?
Site overheads pay for the people and equipment that do not appear in the finished wall. A clerk of works or site engineer, a surveyor for setting out, cube moulds and laboratory fees, water for curing and compaction, a pump, a generator, scaffolding and the transport that keeps a crew on site. The project's specification and the engineer's instructions set what is required on a given job. The estimator decides whether those items are priced as real hours or as a token line.
The mechanism is simple. If the supervision budget is thin, one person covers several tasks and the inspection record falls behind the pour. If the curing water line is thin, curing stops early. If the plant line is thin, a compactor arrives late. None of these looks dramatic at the time. Ask the contractor's office for the site establishment section of the priced bill and check whether the clerk of works is priced for the full programme or only the first few weeks.
What does weak supervision miss on a Qardho site?
Weak supervision misses the checks that happen once and cannot be repeated. Concrete is placed and covered. Backfill is compacted and buried. Reinforcement is fixed and encased. An inspection log that stops for two weeks during a slab pour leaves no record of what went in. A cube result that never arrives leaves no evidence of the mix.
On any hot site, curing and water addition are commonly the first items to slip when nobody is watching the pour, and the damage appears months later as cracking or dusting. Ground conditions below a foundation can differ from the trial pit that was dug elsewhere on the plot, and without a supervisor present at the excavation the founding level is decided by the machine operator. The way to check the local situation is to walk a recently completed building with the client's representative and ask which inspections were recorded and where the records are kept. Then ask the local authority which records, if any, are available for the plot.
How can a client or supervisor close the gap?
Close the gap before the work starts, not during the pour. Put the supervision requirement in the contract as named roles and named records: who signs the reinforcement check, who takes the cubes, who signs the compaction test, who keeps the site diary. Ask for those records at each payment stage, not at handover.
If the priced overheads look thin, ask the contractor to show how the clerk of works, the curing water and the compaction plant are covered across the programme. A contractor who cannot answer has priced supervision as a formality. The contract sets what a client may do about it, so check the payment terms and the defect liability clause before deciding anything. As general practice, engineers require inspection before covering work, and typical intervals and hold points differ by project; confirm the actual hold points against the project's specification and the engineer's instruction.
What to do next
Ask the contractor for the site establishment section of the priced bill and the signed inspection record for the last completed pour. Compare the dates. Then ask the local authority which records, if any, exist for the plot. If the dates do not line up or the record is missing, raise it in writing before the next payment stage and before more work is covered.
Frequently asked questions
Can a low overhead bid still produce good work in Qardho?
It can, if the contractor funds supervision from its own margin. The check is the record, not the price: ask for dated inspection sheets and test results as the work proceeds.
Who should keep the site inspection record?
The project's specification and the engineer's instruction decide this. In practice one named person holds the file on site and the client's representative receives a copy.
