An estimate is a commercial position
Treated as a number, an estimate will not withstand the argument that follows it. Treated as a position — with its basis, assumptions and exclusions recorded — it becomes the reference against which every subsequent variation, claim and forecast is tested.
Why the basis matters more than the number
Two estimates can arrive at the same figure and be worth entirely different amounts eighteen months later. The difference lies in what sits beneath them: whether the quantities are traceable to a documented take-off, whether the rates are supported by first-principles build-ups or by unattributed benchmarks, and whether the assumptions were recorded in terms capable of supporting a variation when the design develops beyond what was priced.
An estimate is priced against a scope, but it is recovered against a contract. A qualification recorded in the estimate but not carried into the contract has no contractual effect. And the obligations that sit between the drawn scope and the written terms — coordination, interface, temporary works, access, sequencing constraints — are recoverable only where the estimate priced them and the contract reflects that it did.
The estimate, the scope and the contract must say the same thing. Reconciling them before signature, without pricing the project out of contention, is the work that determines whether the position holds.
How we approach it
Estimating across civil and MEP scopes
We prepare estimates using first-principles build-ups where the scope warrants the resolution, and rate-based methods where it does not, across civil, structural, mechanical and electrical works. Each estimate is delivered with its basis stated: the documentation it was priced from, the quantities and their source, the productivity and resourcing assumptions applied, and the exclusions and qualifications that define its boundary. Cost breakdown structures are established at estimate stage and carried into delivery, so that the basis on which a project was priced is the basis against which it is subsequently controlled and reported.
Reconciling the estimate to the contract
An estimate becomes recoverable only where its basis is reflected in the terms. We test the pricing basis against the contract being offered — confirming that qualifications and exclusions are carried into the agreed scope rather than left in a covering letter, that the scope priced matches the scope described, and that the obligations sitting between the two are either priced or expressly excluded. That reconciliation is a commercial judgement, not a mechanical one. A bid priced to eliminate every exposure will not win, and a bid priced to win without addressing them will not survive delivery. The work is to identify which gaps carry genuine cost and must be closed, which can be accepted and managed, and which are better resolved through a qualification than a contingency.
Cost planning through concept and definition
Early-phase estimating is a different exercise from tender pricing. With the design immature, the value lies in establishing a realistic range and identifying the drivers within it. We develop cost plans through concept and definition phases, maintain them as the design progresses, and report the movement between iterations so that the reasons for change are visible and attributable rather than absorbed into a revised total.
Benchmarking against comparable projects
A figure means little in isolation. We benchmark estimates against comparable projects and asset classes, adjusting for scope, location, market conditions, delivery model and programme, so that a client understands not only what a project is expected to cost but how that expectation compares to what similar work has actually cost. Where an estimate sits outside the expected range, the useful output is the explanation.
Independent estimate review and challenge
We review estimates prepared by others and test them properly. Whether the quantities reconcile to the documentation. Whether the rates are supportable. Whether the allowances for preliminaries, escalation, risk and contingency reflect the actual profile of the project. Whether anything material has been omitted. The output is a considered position on whether the estimate can be relied upon, and where the exposure sits if it cannot.
Value engineering and quantification
Where a project exceeds its budget, we identify where cost is concentrated, test which elements are driving it, and assess options against their effect on programme, buildability and operational cost — so that a saving made at design stage does not reappear as a variation during construction. We also prepare bills of quantities and undertake quantification and remeasurement through delivery and at final account.
Who we act for
Principals seeking an independent view of what a project should cost before committing to it. Contractors and joint ventures pricing a bid. Delivery partners reviewing estimates prepared on a client’s behalf.
