How do you track defect costs when a Berbera bid looks low?

A low bid does not remove the cost of defects. Defect cost tracking underbidding risks in Berbera come from the same gap: when a tender leaves out correction, protection and testing work to reach a lower total, the cost does not disappear. A low bid does not remove the cost of defects, it moves it to whoever corrects the omissions later, whether that is the client or another contractor, and the split is confirmed against the contract.

Why does a low bid hide defect costs?

A tender total is a sum of items, and items no one writes down cost nothing on paper. They still cost money on site. The items a squeezed bid drops first tend to be ones whose absence shows up late: concrete cover and curing, waterproofing laps and upstands, bedding and compaction around buried pipework, protective screeds over membranes, and the testing or retesting that proves each of them. Each is small in the bill and large in the repair.

Confirm exposure and protection requirements against the project's specification and with the project engineer. Ask the relevant municipal office what records exist for comparable local sites, and walk a recent building to see how exposed steel, fixings and membrane edges have weathered. Read the bill against the drawings: any drawn item with no priced line is a correction budget waiting to happen. Confirm the schedule of rates and any defect liability period against the contract, and take the project engineer's reading of them, rather than assuming a figure.

How do you spot understated correction budgets in Berbera?

Understatement hides in the units, not in the totals. A bid that prices rectification as one lump sum, or as a day rate with no quantity, gives no way to check it later. Read the allowance for remedial work against the areas it must cover.

• Does finishing work have a separate rate for making good after other trades?
• Does excavation include a rate for over-dig and backfill against a wall or pipe?
• Is testing priced per test, with the retest after a failure also priced?
• Is dismantling and refixing of pipes, ceilings or fittings allowed for where an inspection needs it?
• Are materials for repair the same specification as the original, stated in writing?

Where a rate is missing, ask for a written breakdown, not a verbal assurance. If the answer is that the work falls inside another rate, ask which one and how it was measured. A contractor who cannot show the measurement has not priced it. Confirm the contract's mechanism for instructing extra work and what it allows before you rely on it.

How do you track defects once work starts?

Tracking means every defect is written down, priced and signed before it is covered or repaired. Keep one register, agreed in format before award, open to the client, supervisor and contractor, with a number, location, date raised, cause, the instructed remedy, the priced cost under the relevant rate, and a signed close-out. Photograph each item before and after, and keep the photographs with the number.

Control the sequence as well as the paperwork. No covering up until inspection is signed. No payment application without the register reconciled to it. No close-out until the client's representative confirms the repair, and any retest is passed. Where a defect repeats across a block, raise it as one item with a quantity, so the cost can be measured against the original allowance and the difference shown to both parties. Take the project engineer's advice on what counts as an acceptable repair.

What to do next

Before you award, ask each bidder for a written breakdown of the correction, protection and testing lines, and price one sample defect together. That single exercise shows whether the allowance is real. Then write the defect register format into the tender documents and name who signs each close-out.
