COMMERCIAL ASSURANCE CAPABILITY

Verify What Was Executed Before You Approve What Was Billed.

Independent physical and documentary quantity verification designed to give owners and finance teams total commercial visibility.

01 / CLIENT PROBLEM

The Risk of Unchecked Contractor Billing

Contractor billing frequently contains material divergences between tender BOQ quantities, submitted running bills, site measurement sheets, actual physical executions, unapproved variations, and supporting documentation.

Without rigorous, independent physical checks on site, project owners routinely pay for inflated quantities, unexecuted scope, incorrect architectural deductions (e.g. door and window openings in masonry or plaster), and speculative variation claims that compound across successive interim invoices.

02 / WAKEFIELD SOLUTION

Independent Physical & Documentary Verification

Wakefield operates as an independent commercial auditor standing directly between contractor billing submissions and client financial disbursement.

We do not audit from behind a desk. Our quantity surveyors go directly to site to take joint physical measurements (JMS), cross-reference executed work against structural and architectural drawings, analyze item rates against contract terms, and verify that every billed rupee represents verified physical output.

How We Work: Four Commercial Control Gates

Gate 1: Contract & Specification Baseline Deconstruct tender BOQs, technical specifications, measurement rules (IS codes/contract conditions), approved drawings, and agreed unit rates.
Gate 2: Physical On-Site Joint Measurement Execute physical site measurements alongside contractor engineers, record joint dimensional logs, and document site conditions with photographic proof.
Gate 3: Cross-Checking & Deduction Review Cross-verify mathematical extensions, apply mandatory structural deductions, isolate duplicate claims, and evaluate submitted variation rates.
Gate 4: Commercial Certification & Exception Report Issue an itemized reconciliation report with certified payment certificates, clearly stating verified vs. disallowed quantities.

08 / FAQS

Frequently Asked Questions

Contractors often bill on estimates or theoretical drawing take-offs. A quantity audit physically measures the work actually completed on the floor, strictly enforces contractual deduction rules (e.g. openings, overlap margins), and checks item descriptions against approved rates before finance signs off.

We tailor the audit protocol to the project's risk profile. For critical high-value items (such as civil works, HVAC ducting, glazing, custom woodwork, and flooring), we execute 100% physical measurements. Standardized repetitive items can be verified via structured statistical sample checks.

Yes. Even if a project has reached practical completion or the contractor has submitted a final disputed bill, our team conducts forensic documentary audits comparing MB records, as-built drawings, material delivery gate passes, and physical inspections to identify unsupported claims.

Our findings are supported by Joint Measurement Sheets (signed jointly on site) and geotagged photographic evidence. This creates an indisputable factual record that eliminates subjective debate during commercial settlement.
