How do you check testing allowances in low Qardho bids?

A low bid in Qardho often wins because the testing allowance was cut, not because the work was priced better. Concrete cube tests, soil sampling, compaction checks and re-tests cost money, and a bidder chasing the lowest number can leave them out or price them at a token rate. Check the testing allowances in the bill before comparing totals.

What does a testing allowance underbid look like in Qardho?

The first sign is a testing line that exists but cannot cover the tests the specification calls for. A bidder may list one cube test for a pour that needs several, or price sampling without the laboratory fee. The mechanism is simple: the estimator removes or shrinks the line to lower the total, then recovers the cost later through a variation or by skipping the test.

Ask each bidder for a written breakdown of the testing line. It should state the number of samples, the tests, the laboratory and who pays for a repeat when a result fails. Compare that breakdown against the project specification and the testing schedule. If the numbers do not match, ask the bidder to price the difference in writing before you compare totals. For the local picture, ask the municipal engineer's office which laboratories serve Qardho.

How do underfunded quality checks reach the work?

When the allowance is thin, the first tests to disappear are the ones nobody is chasing. A supervisor on a tight programme may accept a delivery without a cube test, or let a compaction check slide because the laboratory is far away and the re-test fee is not covered. The concrete still goes in, the fill still gets compacted, and the record that would have caught a problem is never made.

By the time a defect shows (a cracked slab, a settlement, a water tank base that moves), the test that would have flagged it is months old or missing. Recovery then costs more than the original test because the work has to be opened up. Walk a recent site in Qardho and ask to see the test register: how many tests were specified, how many were done, and what the failed results led to. A register with gaps is the clearest evidence that the allowance did not survive the bid.

How should a client close the gap?

Close it at tender stage, not on site. Write the test types, frequencies and acceptance rules into the specification, name who pays for re-tests, and make the testing line a measured item rather than a lump sum the bidder can trim. General practice is to fix the number of tests against the pour or fill volume and confirm the rates against the project specification and engineer.

Then agree one laboratory and its scope before work starts, so there is no argument later about which tests it can run. Hold the allowance as a separate line in the contract and check it at each payment application. If the contract allows retention or a separate testing sum, confirm the wording with your engineer before you sign, because rules on retention and liability vary by contract.

What to do next

Take the two lowest bids for your Qardho project and ask each bidder for a written testing breakdown: sample numbers, test types, laboratory, and who pays for a failed result. Compare both against the specification and the engineer's testing schedule. If either breakdown is short, request a revised price in writing before you award, and keep that comparison on file.
