How do you catch unrealistic bids in Borama?

A low bid in Borama deserves a careful look before you award. Bid program reviews underbidding risks by comparing each rate against the measured bill of quantities, the method statement and the programme. If an item is missing, underpriced or promised in a duration the plant and crew cannot deliver, the gap reappears later as a variation, a stalled section or a defect.

How does underbidding start in a Borama tender?

Underbidding starts when a bidder prices a different scope from the one you measured. The bill of quantities may list excavation, backfill, hardcore, damp proof membrane and a slab, while the returned schedule prices only the slab. In Borama, where haul distances and material availability can shift, a bidder may also leave out cart-away, water for compaction or curing, formwork, or the cost of working around existing services. Local market rates for aggregate, cement, reinforcement and transport are worth confirming in writing with two suppliers rather than assuming a figure. Unrealistic tender allowances often hide in the preliminaries: supervision, security, temporary water, testing and site clearance. Ask the municipal engineer's office whether the plot has any known constraints, and request the bidder's own take-off so you can trace how the quantity was built up. If the bidder cannot show the build-up, treat the rate as unverified.

What do unrealistic completion promises do to the work?

An unrealistic completion promise compresses the programme until trades collide. A bidder may promise to finish a building in a period that does not allow for curing, blockwork strength gain, or the delivery lead time on imported items. On site, that promise turns into concrete poured before the previous lift is ready, blockwork laid faster than the mortar can carry, or finishes applied to damp plaster. It also pressures the supervisor to accept work that should be rejected. Detection is straightforward: compare the promised duration with the sequence of operations, the crew size and the plant offered. Ask what happens during Gu and Deyr rains if the roof is not closed. Ask where water and power come from. Ask which items the bidder intends to subcontract. A programme that shows no float and no weather allowance is a promise, not a plan. Confirm any duration limit against the project specification and the engineer's programme requirements.

How do bid program reviews underbidding risks in Borama?

Reviews catch the gap by comparing scope, not totals. Build a checklist from the bill of quantities and mark each item: priced, underpriced or absent. In Borama, cover excavation and disposal, backfill and compaction, hardcore, damp proof membrane, reinforcement, formwork, concrete, blockwork, lintels, roof structure and covering, openings, services first fix, plaster, screed and external works. Repeat the exercise for preliminaries, testing and as-built information. Then run the arithmetic: quantity times rate must produce the line total, and line totals must reconcile with the bid sum. Ask each bidder for a method statement, a plant list, a crew list and a programme with dates. Where a rate looks low, request a written explanation of the assumed output, the wastage and the source of material. Award to the bid that is complete and buildable, not the lowest number. Keep the comparison sheet with the tender file so the decision can be explained later.

What to do next

Take the returned bills of quantities and mark every item that is unpriced, priced at zero or left blank. Send those items back to each bidder with a written request to confirm the rate, the quantity and the method before you sign. Keep the replies with the tender evaluation file.
