In brief
- A low bid can stay low only if the supervision it assumes never turns up, so check engineer availability underbidding risks before award, not after.
- Ask for named staff, their other commitments and a written time commitment per week, then confirm the same names on site.
- Put the supervision obligation into the contract and inspect against it, because a bid promise is not evidence of attendance.

A low bid in Berbera can hide an engineer who is not actually available, so the priced supervision quietly disappears once work starts. The bid assumes a person who is already committed elsewhere, or a single engineer covering several jobs. Engineer availability underbidding risks sit in that gap: the rate looks right, the person does not. Check the assumption before award, not after the first pour.
Why does a thin engineer market push bids down?
When few engineers work in a town, a contractor can price a job as if one person covers everything, because nobody forces the split into the open. The bid then carries a supervision allowance that only works if the engineer is on site daily, and that engineer may already run two other contracts. In a small market the same few names can appear in several bids at once, and each bidder may assume the others will not win. The pool of people who can sign off setting out, concrete and compaction can be small, so ask each bidder to name the engineer who will attend, then ask that person which other sites they currently run. If the answer is vague, the allowance is not real.
What does nominal technical oversight do to the work?
Nominal technical oversight means the engineer exists on paper but does not control the work, so decisions default to the crew. Setting out gets checked by the foreman, concrete gets placed without a slump or cube record, and backfill goes in without a compaction test. None of this looks wrong on the day. It surfaces later as a foundation at the wrong level, a slab that fails a core test, or a wall that has to come down. The mechanism is simple: unsupervised work is not wrong because people are careless, it is wrong because nobody with authority stops it. Ask the local authority what records it requires for the plot, then ask the bidder which named person will produce them. A bid that cannot name that person is pricing oversight it does not intend to provide.
How do you test the availability claim?
Test it with documents and dates, not assurances. Ask for the engineer's registration, a list of current projects, and a written commitment of days per week on this site. Then check the same name against the site diary, the inspection requests and the test certificates after work starts. Walk a recent site the bidder finished and ask who signed the concrete records and how often that person attended. Ask what happens when the engineer is away: who covers, and what stops work. Confirm the supervision obligation in the contract, including attendance records, and check what your contract allows if records are missing.
- Named engineer, registration and current commitments
- Written days per week on this site
- Cover arrangements during absence
- Test and inspection records the engineer will sign
What to do next
Before award, send every shortlisted bidder a one-page request: name the site engineer, list that person's other current projects, state days per week on this site, and describe cover during absence. Require the same name on the first site diary entry. If a bidder cannot answer in writing, treat the supervision allowance as absent and reprice the comparison before you sign.
Frequently asked questions
Can a low bid still be genuine if the contractor owns the plant?
Possibly, but plant ownership does not explain a supervision allowance. Ask for the named engineer and their weekly attendance commitment, then verify it against the site diary after work starts.
What if the bidder says the engineer will attend part time?
Part time can work if the contract states which activities require attendance, such as setting out, concrete pours and compaction tests. Put those triggers in writing and check the records against them.
