How do you check temporary electrics competency in Berbera?

Temporary electrics competency in Berbera cannot be confirmed from a CV or a reference letter. A competent temporary electrics team shows documented test results, a sample distribution board and a site you can walk. Ask for those three things before you allow any energising of site power, and check that the person who signs the test sheet is the person who did the work.

What does an unverified temporary electrics claim look like?

An unverified claim is a statement of capability with nothing behind it. A bidder may say the team has wired many sites, or name a large project, but produce no test sheet, no instrument record and no board you can inspect. Ask the bidder how the enclosure, cable insulation and glands will cope with your site's dust, heat and airborne moisture, and ask what the project specification requires for the materials; on some sites these conditions shorten the life of insulation and enclosures, so the gap between a claim and an installation shows up fast. Look for these signs:

• Test certificates with no instrument serial number, no date and no signature.
• A board assembled from mismatched parts, with no label showing the rating of each circuit.
• Cables run across the ground where vehicles and foot traffic pass.
• Earth electrodes described but never shown, or shown without a continuity reading.

The general practice is that every distribution board is tested before it is energised and the results are recorded. Confirm the exact tests and pass values against the project specification and the engineer's instruction, because the required values depend on the system design.

How do you test a bidder's temporary electrics claims?

A bidder's claims are tested with documents, samples and a site visit, in that order. Start with documents. Ask for insulation resistance readings, earth continuity readings and the schedule of tests for the last two sites the team energised. Ask which instrument was used, when it was last calibrated and who holds the calibration record. Then ask for a sample board: a completed assembly with its protective devices, labels and cable entries, built to the same standard the project will use. Finally, ask to walk a site the bidder is running now. Watch how cables are supported, where the earth electrode sits, how boards are locked and whether warning signs are in place. Ask the site supervisor who energises the board each morning and who checks it after rain. If the answers change between the office and the site, the documentation is not describing real practice.

What should the contract and supervision routine cover?

Competency gaps close when the contract names the evidence and supervision checks it. Write into the contract the test records to be handed over, the person responsible for the temporary supply, and the inspection points set around the wet-season conditions your own site experiences. Check what your contract allows before you release any payment tied to energising. On site, keep a simple log: date, board reference, test done, reading, name, signature. A supervisor who signs that log each week creates a record that a later dispute can use. Ask the municipal engineer's office whether it holds any local requirements for temporary supplies, and ask the electricity provider what it needs before it connects. Confirm all limits and tests against the project specification and the engineer, since temporary supply rules depend on the supply type and the installation.

What to do next

Pick the bidder you are considering and send one written request today: test sheets from the last two energised sites, the instrument calibration record, and a date to walk a live site. Set the same deadline for every bidder so the answers can be compared side by side. Award the temporary electrics package only after the records match what you see on site.
