How do you supervise an occupied renovation in Qardho?

Supervising an occupied renovation in Qardho means controlling two jobs at once: the new work and the building that keeps running around it. Damage to existing services is the failure that costs most, because a broken pipe or cable inside a finished wall is invisible until it leaks or fails. The defence is a recorded condition survey before demolition, agreed hold points, and inspection before every cover-up so the work is seen while it is still open.

Why does an occupied building hide supervision gaps?

People live or trade in the rooms next door, so work is done in short pushes and services are rerouted to keep water and power on. Each reroute is a decision that can pass unrecorded. A pipe shifted to clear a new opening may sit too shallow in a floor screed, or a cable may be pulled tight around a corner. Nobody photographs it, and the next trade covers it. A supervisor who visits once a day at the busiest hour sees finished surfaces and misses the moment the service was moved. Ask the client which rooms stay in use and which services cannot be shut off, then write those constraints into the programme.

What do missed inspections look like in the work?

Missed hold points show up as services that were never pressure tested or megger tested before covering, and as openings cut without checking what runs behind them. General practice is to test buried water pipe before backfilling or closing, to test drainage before floors go down, and to test circuits before plaster or fixing. Confirm the exact tests and acceptance limits against the project specification or the project engineer. In an occupied building the warning signs are practical: no test certificate on file, no dated photographs of the open trench or chase, and instructions given at the doorway rather than in writing. Walk a recently handed-over renovation with the client and ask where the previous contractor recorded its tests; what you find there tells you what to expect on your own site.

How do you close the gap before work starts?

Agree the rules in the contract and the programme, not on site. Before work starts, walk every room with the client and record the condition of walls, floors, doors, fittings and visible services with dated photographs. Mark the routes of water, drainage and electrical services you can trace, and note which you cannot. List the hold points as named stages: before backfilling, before closing chases, before screeding, before painting. Say who inspects each one, how much notice they get, and where the record is filed. Check what the contract allows on access hours, water and power shutdowns and protection of the client's furniture, because those clauses decide what the supervisor can actually enforce. Ask the municipal engineer's office what permit conditions apply to work in an occupied building before you price the job.

What to do next

Take your tender documents to a recent occupied renovation in Qardho and ask the client which hold points were signed off and which were skipped. Then write your own hold point list with notice periods into the contract before signing. If the contractor will not accept staged inspection before cover-up, treat that as a priced risk, not a detail to settle later.
