Red Flags in a Contractor's Proposal and What Each One Really Means

The signals inside a construction proposal that predict claims, delay and abandonment, and the specific question that turns each one into a priced answer before you sign.

A proposal is a sales document, and its gaps are usually deliberate. The dangerous bid is not the one that is obviously poor but the one that looks clean and cheap because scope has been quietly moved outside it. Reading for red flags means reading for what is absent: exclusions, quantities, named products, programme logic and the entity actually promising to perform.

Why these keep happening

Owners compare proposals on the bottom line because that is the only number in the same place on every document. Contractors know this. The commercial skill in bidding is not sharpening a price, it is arranging a document so the lowest defensible number appears on page one and the recovery routes appear on pages nine to fourteen. Foreign owners are especially exposed, because the recovery routes rely on local norms they have no way of testing.

1. A lump sum with no measured quantities behind it

A single figure for a whole building cannot be interrogated. When a variation arrives, there is no rate to value it against, so every change is negotiated from scratch and from a weak position. The absence of a bill of quantities or a schedule of rates is not simplicity, it is the removal of your pricing reference.

• Avoid it by: Require a schedule of rates or a priced breakdown by element even where the contract is a lump sum.
• Proof it is closed: The contract annexes a rate schedule that variations must be valued against.

What it costs you: Every change order is priced at the contractor discretion rather than against agreed rates.

2. A long exclusions list written in general language

Exclusions such as external works, authority connections, dewatering, testing and commissioning, or anything not shown on drawings can move a large share of the real cost outside the price. Written loosely, they let the contractor decide later what the exclusion covered. Owners read the exclusions page quickly because it appears after the number they were waiting for.

• Avoid it by: Price every exclusion yourself and add it to the comparison, or require the bid to include it.
• Proof it is closed: A comparison sheet showing each bid at the same scope, with excluded items priced in.

What it costs you: The gap between contract sum and final cost, often the largest single overrun on a first project.

3. Provisional sums doing the heavy lifting

Provisional sums are legitimate for work that cannot be defined yet, but a bid that hides uncertainty in several round allowances has not priced the job. Because the allowance is spent and then adjusted, the headline figure is a placeholder while the contractor is protected either way.

• Avoid it by: Cap the total value of provisional sums allowed and require a defined process for converting each one.
• Proof it is closed: A register of provisional sums with the date each must be resolved into a fixed price.

What it costs you: A budget that behaves like an estimate while you have treated it as a fixed price.

4. Specified products replaced by or equivalent

Every material line reading or equivalent hands the substitution decision to the party paying for it. Two bids can appear identical and deliver visibly different buildings: different sanitaryware, different lifts, different sealants, different lifespan. On a project you intend to sell or let, the finish is the product.

• Avoid it by: Name products and manufacturers for the items a buyer or tenant notices, and require written approval for substitution.
• Proof it is closed: An approved products schedule attached to the contract, with a substitution approval procedure.

What it costs you: Lower sale prices or rents on a building that reads as cheaper than the one you priced.

5. A front-loaded payment schedule

A large advance and early milestones unrelated to measured progress means you are funding the contractor rather than buying work. If the company is using your advance to finish another project, your programme depends on that project going well. This is the pattern behind most abandoned sites.

• Avoid it by: Tie payments to measured progress certified by someone acting for you, with retention held and an advance payment guarantee.
• Proof it is closed: Each certificate references measured quantities and is signed by your engineer or reviewer.

What it costs you: Money paid for work not built, recoverable only through dispute.

6. A programme with no logic and no float

A bar chart showing an attractive completion date with no sequence, no dependencies and no allowance for approvals is a marketing date. It cannot be used to test whether a delay is the contractor problem or an authority matter, so every slip becomes arguable.

• Avoid it by: Require a logic-linked programme with approval and inspection activities shown, updated monthly.
• Proof it is closed: A baseline programme accepted in the contract and monthly updates showing progress against it.

What it costs you: Loss of the ability to prove delay, which is the loss of the delay remedy.

7. A bid from a different entity than the one that will sign

Proposals arrive on group letterhead while the contract is offered from a smaller registered entity with a different balance sheet and a different classification. The record you evaluated may belong to a sister company that carries no obligation to you.

• Avoid it by: Confirm the signing entity early and require a parent guarantee where the record belongs to the group.
• Proof it is closed: The contract names the verified entity, with any guarantee executed at signature.

What it costs you: A counterparty with no assets to meet a claim, and warranties that cannot be enforced.

A short check before you sign

• Every bid restated on identical scope, with exclusions priced in and shown separately.
• A rate schedule or elemental breakdown attached, sufficient to value changes.
• Named products for the items a buyer will see and touch, with substitution requiring approval.
• Payments tied to measured progress with retention, plus a guarantee against any advance.
• A logic-linked programme including authority approvals and inspections, accepted as a baseline.
• The signing entity verified, with a guarantee where the reputation belongs to a parent.

If it has already happened

If you have already signed a bid with these gaps, do not wait for the first claim. Commission an independent review of the contract and the current site progress, establish the real cost to complete including the excluded items, and put a measured valuation process in place before the next payment leaves. Then negotiate: a contractor holding a weak document still wants the remaining work and a reference, and that is the leverage you have left. Take local legal advice before withholding any payment, because the consequences of doing that wrongly are worse than the original gap.
