In brief
- Bid scope comparisons in Borama only work when every bid is priced against one written scope, not the contractor's own summary.
- Items left out of a bid rarely appear on site, and weak supervision lets the gap stay invisible until a test or inspection fails.
- Award with the priced scope as a contract annex and put each omitted or provisional item on its own inspection point.

Bid scope comparisons in Borama start with one written scope that every bidder prices line by line. When each contractor submits its own summary, the prices are not comparable, and weak supervision then hides the difference. The award goes to the lowest total, the missing items stay missing, and the client pays for them later or builds around a gap.
What makes two Borama bids noncomparable?
Two bids are noncomparable when they cover different work, materials, or testing. One contractor prices excavation to a stated formation level and includes a plate load test or a density check; another prices excavation only and leaves the test as a client cost. One prices imported hardcore with a stated layer thickness and compaction method; another prices local fill. The totals differ, but so does the work.
Read the bills of quantities line by line, not the summary page. Look for qualifications in the covering letter, and for words such as "subject to", "excluding", and "by others". Check whether the bidder states a rate for extra depth, a method for dewatering, or a laboratory for concrete cube testing, or leaves those blank to be agreed later.
Ask each bidder to resubmit on one common scope sheet before any comparison. That sheet should state units, quantities, and what each rate includes. Confirm the ground and site conditions against what the municipal engineer's office holds for the plot, and set the specification against the project's drawings and engineer's instructions.
How do missing scope items survive on site?
A missing item survives because nobody holds an inspection point against it. Suppose one bid omits a compaction test on imported fill. The fill still arrives, the roller still runs, and the pour proceeds. No test result exists, so nothing shows the omission until a later stage, a settlement crack, or a rejected structure.
Weak supervision misses this because the inspection list is built from the contractor's programme, not from the gap list produced during bid comparison. The supervisor then checks what is being built, not what should have been built. The client sees progress and assumes the scope was met.
The mechanism is simple. A cost the bidder did not price becomes a task nobody schedules, and a task nobody schedules becomes a check nobody makes. Common gaps in this pattern include setting out records, soil or fill testing, concrete cube testing, curing records, and as-built levels. Each one leaves a document trail or a physical trace, so each one can be made visible. Request test records as the work proceeds, not at handover, and walk a recent site to see what records the supervisor there actually keeps.
How do you close the gap before award?
Make the priced scope a contract annex, and make every provisional or omitted item its own inspection point with a named person and a record.
- Produce a comparison sheet listing every scope item against every bidder, with blank cells shown as blanks, not zeros.
- List each blank as a risk item with an owner, a check method, and the stage where the check happens.
- Ask each bidder to price the blank items before award, or state in writing who carries them.
- Put each priced item into the supervision inspection plan, so the check happens even when the item was not in the original programme.
- Keep copies of test requests, delivery notes, and level records in one file on site.
Confirm what the contract allows before you change a scope or hold back any payment. Ask the project's engineer to confirm testing frequencies and hold points against the specification, since these vary by project.
What to do next
Take the three lowest bids on your Borama project and rebuild one comparison sheet from their actual line items. Mark every cell where a bidder left an item out or wrote "excluded". Send that marked sheet to each bidder and ask for a repriced version on the same scope, then use the marked items as the first entries in your inspection plan before you award.
Frequently asked questions
Can I compare bids that use different units?
No. Convert every quantity to one unit and one specification before comparing totals, and ask each bidder to confirm the conversion in writing. If a bidder prices by cubic metre and another by truckload, the totals describe different work, and the comparison is meaningless until both are repriced on the same basis.
Who should hold the gap list produced during bid comparison?
The client or the client's representative should hold it, and the site supervisor should use it as the starting point for the inspection plan. Ask the project's engineer to confirm which items are hold points, and keep the list in the site file so it survives changes of staff.
