Formal measurement, cost planning, and contract administration aligned with the Australian Institute of Quantity Surveyors (AIQS) Standard Method of Measurement and Best Practice Costing Manual. From cost plans through to final account.
Properly measured quantities are the foundation of fair tendering, accurate progress payment, and clean variation pricing. Without them, projects bleed value through dispute, double-counting, and unagreed scope.
A common Bill of Quantities lets every tenderer price the same scope on the same basis. Tender returns become directly comparable and the lowest commercially-credible price can be identified objectively, eliminating the apples-to-oranges problem of unstructured tendering.
Monthly progress claims measured against the BOQ give the client confidence that payments reflect actual work in place — not just contractor invoices. This protects cash flow on both sides and is essential under the SOPA legislative framework in Queensland.
Variations priced against the contract BOQ rates and ASMM measurement rules can be settled efficiently. Where star rates are required, the QS builds them transparently from first principles. The result is fewer commercial disputes and faster final account closure.
Stage cost plans (A-F under AIQS) track project economics from concept through detail design, flagging cost growth early when there is still time to redesign. Combined with elemental cost analysis, the cost plan becomes the central commercial control document.
As an independent QS, Cenex is not aligned with any contractor or designer. Our measurement and certification is impartial, defensible, and prepared to the standards expected by Queensland Treasury, Department of State Development, TMR, and major asset owners.
A measured BOQ exposes the cost drivers — quantities, rates, prelims, contingency. That visibility lets the client and contractor allocate risk rationally rather than carrying generous contingencies blind. AIQS-aligned measurement is the engine that makes risk-based pricing possible.
A complete commercial toolkit for the life of the project — from cost plan through final account.
Stage A (concept) through Stage F (post-tender) cost plans built on AIQS elemental structure. Each stage tightens the estimate as design progresses, with clear documentation of assumptions, exclusions, design contingency, and escalation. Cost plans are the spine of project commercial control.
Fully measured, fully described BOQs prepared to ASMM, the Civil Engineering SMM, or TMR schedules of rates. Each item is traceable back to the source drawing or specification, with quantity take-offs documented for client audit. Suitable for tender, contract, and post-tender administration.
Monthly site-measure valuations against the BOQ with payment certificate recommendation. Includes assessment of stored materials, retention, set-off, and any disputed items. Compliant with Queensland Building Industry Fairness (Security of Payment) Act timing and notice requirements.
Independent assessment of contractor variation claims using contract BOQ rates, derived rates, or first-principles star rates as appropriate. Includes commercial recommendation, risk assessment, and supporting calculations. A defensible, audit-ready variation register is the single biggest protection against final-account dispute.
Monthly cost reports tracking actual vs budget, forecast cost to complete, and cash flow projection. Reporting is structured around AIQS elements and the project WBS so that the same numbers tie to the cost plan, the BOQ, and management dashboards. Ready for board and lender consumption.
Complete final account preparation reconciling original contract sum to final paid value, with full audit trail of variations, valuations, set-offs, and adjustments. Resolves outstanding commercial issues and closes the project commercially. Cenex's final accounts are routinely accepted without challenge by both client and contractor sides.
Whether you need a Stage C cost plan, a fully measured tender BOQ, monthly progress valuations, or independent variation assessment, Cenex's AIQS-aligned QS team is ready to help.
