How do you check conduit routing in Qardho?

Conduit routing in Qardho decides whether wiring can be pulled, replaced and earthed years later. The work disappears under screed, blockwork and plaster, so a supervisor who is not on site at the right hour sees nothing to check. Supervision gaps in conduit routing rarely show on handover day. They surface when a circuit fails, a draw rope snaps, or someone opens a wall to find a crushed pipe and damaged concealed wiring.

Where does conduit routing in Qardho go wrong without supervision?

Most failures happen in the hours before a pour or a block course closes the route. A duct is laid too shallow, a bend is made with a tight radius, or two runs cross where a fixing will later be drilled. A second crew that arrives after the first has gone can put a block on top of an unrecorded run. In hot inland conditions, direct sun can make PVC conduit soft and easy to deform under foot traffic, and a steel run left open can take in grit before it is capped. None of this needs a deliberate shortcut. It needs a gap in who is watching when the work is covered. Ask the site supervisor which hours of the day are covered on the Qardho job, and whether the electrical first fix has its own inspection point before backfilling or blockwork.

How do you detect routing faults before plaster hides them?

Detection is a sequence of checks, not one look. Walk each route before it is covered and compare it with the marked-up layout drawing. Confirm depth and cover against the project specification, since general practice for buried conduit varies by system and the engineer's detail governs. Check the conduit size against the cable it must carry, and that bends are formed with the correct spring or bending tool rather than forced. Pull a draw rope through each run and record it. Test steel conduit for continuity of the earth path with a multimeter, with the results written down and signed. Photograph every run with a tape measure in frame, and photograph the wall or slab location so the route can be found later. If your contract needs third-party evidence, ask the laboratory or testing firm for its method statement and rate before work starts.

Who closes the supervision gap on a Qardho site?

The client, the project manager and the site supervisor each hold one part of the fix. The client writes the inspection points into the contract and links payment stages to signed records. The project manager schedules a hold point before every pour or block course that covers conduit, and puts a named person on it. The site supervisor keeps a routing register: date, route, photo, continuity reading, signature. Where the contractor's own team does the wiring, ask who checks them and how a second pair of eyes is provided. Ask the municipal engineer's office what drawings or inspection records it holds for the area, and whether any permit condition applies to buried services. If supervision is thin, a clerk of works or an independent inspector for the first-fix stage is a direct way to close the gap.

What to do next

Pick one upcoming pour or block course on the Qardho job. Before it is covered, walk the conduit routes with the layout drawing, pull a draw rope through every run, record continuity readings for steel conduit, and photograph each route with a tape in frame. Sign the register with the site supervisor, then compare the next contractor bid against the same inspection points.
