In brief
- A low lintel bid often omits propping, bearing length, concrete cover and curing, not the concrete itself.
- Cracks above openings show up weeks after the lintel goes in, when the scaffold is down and the bid looks settled.
- Compare bids on a written scope, not on the total, and ask each bidder to state what the price leaves out.

Lintel installation underbidding risks in Borama start with a bid that carries the concrete but leaves out the work around it. The block, the steel, the propping, the bearing into the wall and the curing days are where the real cost sits. A price that looks low is often a scope that stops at the formwork.
What does a low lintel bid leave out?
A low bid usually omits the items that are hard to see once the wall is finished. The lintel itself is a small piece of concrete. The work that holds it in place and lets it gain strength is the part a rushed estimate drops.
Look for these omissions in any Borama lintel price:
- Bearing length on each side of the opening, and the pad or block course that carries it.
- Props and their duration, including the days after the pour.
- Concrete cover to the reinforcement, and spacers to hold it.
- Curing water and the labour to keep the lintel wet.
- Lifting and placing over doors and windows, where access is tight.
Ask each bidder to state in writing what the price excludes, then compare those exclusions against your schedule. Confirm the required bearing, cover and cure with the project engineer or the specification before comparing totals.
How do weak cost assumptions turn into cracking above openings?
Weak assumptions show up as cracks above doors and windows, and they appear after the trades have moved on. If the estimate assumes the mason will prop from spare timber, the prop may be too short, too few or removed early. If it assumes the lintel can bear on a thin block course, the wall crushes at the ends of the opening.
In a hot, dry inland climate, concrete loses water fast, so curing is not a formality. Curing is general practice, not a local rule, and the duration and method should come from the project specification or the engineer. A lintel that dries too quickly gains strength slowly and deflects more under the wall above. The crack then opens diagonally from the corner of the opening.
Watch the sequence. If the blockwork above the lintel starts before the concrete has cured, the load arrives early. A bid that left out propping and curing carries that risk forward to the site, so check the props and the cure on every opening rather than assuming the price covered them.
How do you catch an unrealistic tender allowance in Borama?
You catch it by comparing scope, not totals. Give every bidder the same written schedule of lintels, with openings, bearing, cover, propping and curing listed as separate lines. Then read each return against that schedule.
Walk a recent site the bidder has completed and look at the openings. Ask when the props came out and how the lintel was cured. Ask the municipal engineer's office whether it holds records or drawings for the type of work you are pricing. Ask two suppliers for written quotes on mesh, cement and spacers so you can test the material lines in the bid.
Where the bid is low on one line, ask what the bidder plans to do. A written answer is easier to hold to than a verbal promise, and your contract may already set out how variations and omissions are handled. Check what your contract allows before you accept or reject the return.
What to do next
Write one lintel schedule for your Borama build, covering bearing, cover, propping and curing as separate lines. Send it to at least three bidders and ask each to state exclusions in writing. Compare the returns line by line, then ask the municipal engineer's office for any records that help you check the local ground and opening details.
Frequently asked questions
Why is the cheapest lintel bid in Borama not always the best value?
Because the low total often covers only the concrete and steel. Propping, bearing, cover and curing sit outside the price, and you pay for them later as repairs or cracks above the openings.
How soon do cracks above openings appear after a lintel is installed?
They can appear as the wall above loads the lintel and the concrete is still gaining strength. In hot, dry conditions the lintel dries quickly, so curing and propping times should follow the specification or the engineer's instruction.
