Khafji is a coastal town, and that shapes where a wiring job starts. The centre of Khafji sits about 9 m above sea level (SRTM open elevation data), and the town is about 2 km from the sea coast (OpenStreetMap). For a duplex, this means the technician should first check how the building's supply arrives and how the earthing and distribution boards are laid out, since salt air and low, flat ground can affect metalwork and connections over time. These are the first points to confirm before any cable is pulled.

Some things can only be settled at the site visit. The technician should walk through both units of the duplex, note the number and location of outlets, lighting points and split AC positions, and check whether the existing wiring is to be reused or replaced. The visit also covers the quantity survey, which is charged at SAR 150–400 per visit, and it is the moment to decide whether the wiring is part of a wider job. If the duplex is being finished at the same time, the walls, ceilings and floors may still be open, which affects how cables are routed. Split AC supply and installation is priced at SAR 350–900 per unit, so the number of units should be fixed on site and not assumed in advance.

For the technician, a few practical notes help the job run smoothly. Ask the owner whether a false ceiling is planned, because gypsum board false ceilings cost SAR 40–90 per m² and any ceiling cabling should be routed before boards go up. Plastering with guides is priced at SAR 15–35 per m² and painting with surface preparation at SAR 8–25 per m², so wiring chases should be finished and checked before those trades begin. Where tiling is planned at SAR 25–60 per m², confirm socket and switch heights early so they sit cleanly in the finished surface. Record every route on a drawing and leave a clear note of the distribution board layout for the owner.

In a duplex, the two floors often share lines, so tests are done floor by floor.
