Solvix International provides BOQ review and cost estimation check services for developers, employers, contractors, subcontractors, consultants, funders, and legal teams that need an independent commercial sense-check before numbers are relied upon for tendering, budgeting, negotiation, or change decisions. We review the Bill of Quantities, estimate build-up, drawings, specifications, scope narratives, measurement basis, provisional sums, contingencies, and pricing logic to identify omissions, duplication, abnormal quantities, rate inconsistencies, and commercial blind spots.
Review whether the BOQ and estimate properly reflect the intended scope, packaging strategy, and design information available at the time.
Identify where quantity, rate, allowance, or build-up assumptions may distort bid comparisons, budgets, or downstream commercial decisions.
This service can be delivered as an early-stage budget check, pre-tender BOQ review, tender evaluation support exercise, estimate validation for management approval, or targeted review of specific trade packages and change items.
Check whether the BOQ structure aligns with the project scope, work breakdown, trade interfaces, and procurement plan.
Review major quantities, units of measure, take-off assumptions, and consistency with drawings or design parameters.
Assess whether rates, preliminaries, provisional sums, wastage, productivity, and contingencies appear commercially coherent.
BOQ and estimate problems are usually found late, at tender comparison, valuation, or final account. An early review identifies the gaps and inconsistencies while they can still be corrected.
Check of scope coverage, measurement, and structure before the BOQ is issued to bidders.
Independent review of an internal estimate or cost plan before budget approval.
Normalisation of priced BOQs so that bids can be compared on a consistent basis.
Testing of unit rates and build-ups for consistency, completeness, and market credibility.
Assessment of whether allowances are adequate for the design status and risk.
Review of BOQ errors and omissions that affect valuation and change control.
Even well-prepared tender packages and internal estimates can contain embedded uncertainty. Missing scope, duplicated items, optimistic productivity assumptions, inconsistent measurement rules, unrealistic provisional sums, or unbalanced pricing can distort procurement decisions and create avoidable downstream disputes. An independent review helps decision-makers understand whether a number is robust, where the major commercial sensitivities sit, and what should be corrected before the project proceeds.
Are there notable omissions, overlaps, or double-counted areas across
BOQ sections, packages, or trade interfaces?
Do the major quantities appear consistent with the available drawings,
specifications, and design assumptions?
Do the rates and build-ups look internally coherent, market-credible, and
comparable across bidders or estimate versions?
Are provisional sums, contingencies, exclusions, clarifications, and
assumptions adequate for the design maturity and risk profile?
Would the current BOQ or estimate create procurement, budget,
valuation, or change-management problems later if left uncorrected?
Our review approach is structured enough to support management decisions, bid assessments, and formal commercial records, but flexible enough to suit the level of design maturity and information available. The methodology can be applied at concept level, developed design, tender issue stage, post-bid comparison, or during live change control where a quantity and pricing sense-check is needed.
identify the estimate basis, issue status of drawings and specifications, exclusions, qualifications, and pricing assumptions.
compare BOQ sections or estimate packages with the intended project scope, interfaces, and procurement strategy.
review key measured quantities, unit selections, take-off logic, and consistency with the available design information.
test rate formation, labour and material assumptions, preliminaries, wastage, productivity, contingencies, and provisional sums.
compare between bidders, estimate revisions, historical data sets, or internal benchmarks to highlight outliers and risk areas.
issue a concise review matrix with material issues, commercial implications, and recommended actions.
The quality of a BOQ review depends on the quality of the underlying information. We work with whatever information set is available while making clear where design maturity, incomplete records, or bidder qualifications limit certainty. That transparency helps clients understand both the result and the confidence level behind it.
A BOQ review tests scope alignment, quantity logic, units, section structure, provisional sums, pricing assumptions, and the overall commercial reliability of the document.
No. Solvix can also review cost plans, estimate build-ups, schedules of rates, trade-package pricing, and change quotations where a full BOQ is not available.
Yes. BOQ and estimate reviews often feed directly into tender evaluation, cost verification, variation strategy, and later claims or expert work where commercial records are scrutinised.
We combine commercial review, project-controls awareness, and dispute-conscious thinking so the findings are useful both for live procurement decisions and for later auditability.
Our outputs are designed to show not only what may be wrong, but why it matters commercially and what action should be taken next.
Where needed, we can connect BOQ and estimate findings to procurement advisory, tender evaluation, change management, cost verification, quantum support, and formal dispute strategy.
