Expert Witness (Quantity Surveyor)

Clear, Impartial Cost Analysis for Complex Disputes

Construction projects can become complex when cost disputes arise, particularly around valuation, variations, delays, or contract interpretation. In these situations, independent expert opinion is often required to support fair and evidence-based resolution.

At Leighton Rowe, we provide Expert Witness services as Quantity Surveyors, delivering independent, evidence-based cost analysis to support legal, contractual, and dispute resolution processes.

Our role is to provide clear, impartial, and professionally substantiated opinions on construction costs and financial matters.




What is a Quantity Surveyor Expert Witness?

A Quantity Surveyor Expert Witness is an independent professional who provides specialist opinion and analysis on construction cost matters during disputes or formal proceedings.

This may include court cases, arbitration, adjudication, or contractual disputes where an objective assessment of cost, valuation, or financial impact is required.

The expert witness does not act for one party commercially, but instead provides independent analysis based on industry standards, contract documentation, and verified project data.




When is an Expert Witness Needed?

Expert QS input is commonly required in situations such as:

 Disputes over progress payments or final accounts

 Variation valuation disagreements

 Claims related to delay or disruption costs

 Contract interpretation issues affecting cost outcomes

 Construction defect or scope-related valuation disputes

 Formal dispute resolution processes (adjudication, arbitration, litigation)

In these cases, independent technical expertise is essential to support fair and informed decision-making.




What Does an Expert Witness Report Include?

Our Expert Witness reports are structured, evidence-based, and prepared to meet formal dispute resolution requirements.

They typically include:

 Independent review of project documentation

 Cost analysis based on contract terms and scope

 Evaluation of progress claims and variations

 Assessment of disputed valuations or financial claims

 Reference to industry standards and QS methodologies

 Clear, logical conclusions supported by evidence

Reports are prepared in a clear format suitable for legal and contractual proceedings.




Why Independent QS Expertise Matters

In construction disputes, financial disagreements often arise from differences in interpretation rather than intent. Without independent assessment, these disputes can escalate, leading to delays, increased costs, and unresolved contractual issues.

An independent Quantity Surveyor Expert Witness helps:

 Clarify technical cost matters

 Provide objective, evidence-based analysis

 Support fair dispute resolution outcomes

 Reduce ambiguity in contractual interpretation

 Strengthen transparency in financial claims

Independent expertise ensures decisions are based on facts rather than assumptions.
