When construction disputes arise, clarity and independence are critical.
MBM’s Expert Witness team delivers precise, defensible analyses on variations, delays, defects, and damages. We translate complex technical and contractual issues into clear evidence that stands up in adjudication, mediation, and court.
Working with law firms, strata managers, insurers, and contractors, we provide expert reports, rebuttals, and quantum assessments that bring confidence to the decision-making process. Our role is to uncover the facts, test the numbers, and give clients the certainty they need to resolve disputes with authority.
Our Experts
Expert Witness Services
Contract Disputes
We provide independent cost analysis to assist in resolving contractual disputes arising from valuation, entitlement, or scope interpretation. Our experts assess competing claims, identify key cost drivers, and prepare reports that clarify what is reasonable, measured, and supported by evidence.
Defect Rectification Costing
When workmanship or material failures occur, MBM provides independent cost assessments to determine the reasonable cost of rectification. We analyse expert scopes, contractor estimates, and design documentation to ensure that claimed costs reflect the actual extent of defective works and are consistent with industry rates and methods.
Security of Payment Act (SOPA) Matters
Our team supports claimants and respondents in adjudication proceedings under the Building and Construction Industry Security of Payment Act. We prepare or review payment claims, payment schedules, and adjudication submissions, providing clear and substantiated cost assessments that address entitlement, quantum, and reasonableness.
Variation & Change Order Valuations
Disputed variations are a leading source of cost escalation and conflict. MBM independently assesses the value of variations and change orders by reviewing contract provisions, pricing methodologies, and supporting evidence. Our valuations are transparent, consistent with contractual terms, and based on realistic construction rates.
Delay & Disruption Claims
We assess the cost implications of delay and disruption, working alongside programming experts to quantify prolongation costs, acceleration measures, and loss of productivity. Our approach ensures claimed costs are linked to actual impacts and supported by credible contemporaneous records.
Final Account Settlement
We assist in the independent review and negotiation of final accounts, identifying discrepancies, omitted works, or overclaims. Our reconciliations provide a clear position on the reasonable final contract sum and help parties reach resolution without unnecessary escalation.
Loss & Expense / Damages Assessments
Where losses are claimed due to breach, termination, or disruption, MBM quantifies the direct and consequential financial impacts. We test claimed losses against evidence, review underlying assumptions, and provide a defensible assessment of reasonable entitlement.
Insurance Claim Cost Assessments
We prepare and review reinstatement or repair cost estimates in insurance matters, ensuring that claimed costs are aligned with policy coverage, scope of damage, and realistic construction rates. Our assessments support insurers, loss adjusters, and insured parties in achieving fair outcomes.
Reasonableness Reviews
We provide independent peer reviews of third-party estimates, identifying areas of overstatement, duplication, or inconsistency with current market pricing. Our reviews are frequently relied upon by solicitors and clients to test the robustness of opposing expert opinions.
Cost-to-Complete Assessments
In partially completed or suspended projects, MBM determines the reasonable cost to complete remaining works. We analyse progress, scope, and contract status to provide a clear, defendable estimate that supports commercial decisions and dispute resolution.
Replacement & Remediation Cost Analysis
We prepare cost analyses for rebuilding or remediation scenarios, commonly used in insurance, strata, and defect litigation. Our reports establish the realistic cost of replacement to the pre-loss condition or to achieve compliance with current standards.
Independent Scope Reviews
MBM independently reviews defect or rectification scopes prepared by other experts to confirm completeness, appropriateness, and alignment with the contract and building code requirements. This ensures that cost assessments are based on a sound and defensible scope of work.
Litigation Support
We support legal teams throughout the dispute process, from early quantum advice to joint expert conclaves and giving evidence in court. Our experts prepare clear, well-reasoned reports that comply with expert witness codes of conduct and withstand cross-examination.
