In brief
- When a bidder has no experienced mentor on site, the cost of supervising trainees and redoing their work often never enters the tender.
- Ask for named site staff, their role and who signs off completed work, then compare that list with the priced labour and supervision lines.
- Close the gap by pricing a mentor day rate into the bill, agreeing a definition of finished work and holding weekly inspections against it.

Mentor availability is one factor that can decide whether a bidder can staff trainee crews, so when the tender has no line for that person, an estimator can leave out the hours a mentor spends checking setting out, formwork and cover, and the bill still looks complete.
How does missing mentor availability end up in a low bid?
A bidder without a mentor prices only the visible trades.
Trainee crews need someone senior on site to check before concrete goes in, to sign off steel fixing and to correct work while it can still be corrected. That person costs money: a salary, travel and time away from other jobs. If the bidder has nobody available, the estimator has three choices. Price an outside mentor at a rate the bidder cannot control, leave the cost out and hope the work passes, or assume the trainees will absorb the checking themselves. The third option wins the tender and loses the quality. An estimator who leaves the mentor out of the priced hours is betting that an inspection will not catch the gap before the pour, and a missing mentor shows up in that bid as a supervision line with nobody named against it.
What does the missing mentor cost on site?
The cost moves to the client, as rework and delay.
The crew may not know the work is wrong until someone qualified inspects it. Removal and rebuilding then costs more than the original supervision would have. A second sign is a flat learning curve: the same mistake repeats on the next floor or the next unit because nobody corrected the method. A third sign is paperwork. Trainee attendance registers can look strong while the actual inspection records are thin, which is why attendance alone does not prove competence.
How a reader checks this locally: ask the bidder to name the person who will sign each inspection before a pour, and ask for that person's record on a comparable job. Ask the bidder for references to comparable completed work, and visit a site only if one is available and accessible, then ask who checked the steel and the levels and look at the finished surface for evidence of correction.
How do you detect the gap before award?
Read the priced labour and supervision lines against the staff list.
Ask every bidder for the same schedule: named site staff, their role, their years on similar building work, and the person who holds sign-off authority. Then compare. If the labour line prices only trainee rates and the staff list names no mentor, the bid cannot deliver what it promises. If a mentor appears in the list but not in the priced hours, the bidder intends to borrow one from another contract, and that person may not be available when the pour is ready.
Ask two things in writing before award: the monthly hours the mentor will be on this site, and the definition of finished work the bidder will be held to. Both belong in the contract, and the client's team should confirm what the contract allows before holding retention or issuing variations. Ask the client's engineer, or the office named in the contract, which inspection stages the project requires. Take the required supervision ratio from the project specification and confirm it with the engineer, never assuming it from another job.
What to do next
Pick one current tender in Garowe and ask the client's engineer, or the office named in the contract, how and whether an addendum is issued for it, then request that each bidder submits a named mentor, the site hours committed, and a one-page method statement for who checks steel and setting out before each pour. Add the same requirement to the priced labour schedule. Then score the bids against that list, not only against the total.
Frequently asked questions
Can a bidder without a mentor still win on price?
Yes, and that is the risk. A bid with no mentor in the priced hours looks cheaper because the checking and correction time is missing. Compare the staff list and the supervision hours, not just the total.
Who should approve the mentor on a Garowe building job?
The client's representative, using the same evidence a supervisor would need: named person, relevant site experience, and a written role in the inspection sequence. Ask the client's engineer, or the office named in the contract, which inspection stages the project requires.
