Four reasons why lawyers instruct Lewis Woolcott
Disputes are won on the quality of the evidence and the credibility of the people who give it. Lawyers who instruct us need an expert who is persuasive under cross-examination, clear on paper and dependable on deadlines.
Led by proven experience
Our quantum and delay experts bring decades of hands-on project delivery, and have been appointed, reported and given evidence in formal proceedings. Under highly credentialled leadership, we have the right expert for your matter.
Independent and defensible
Our experts give opinions that remain credible under cross-examination, grounded in evidence, internationally recognised methodology and commercial reality. Their reports have been preferred in adjudications and adopted in formal proceedings.
Data-enabled analysis
Our forensic analysis is powered by Logic+, LWARE's proprietary scheduling platform. Programs and project records are interrogated faster, findings are more transparent, and the evidence is presented to tribunals with greater clarity, on the timescales formal proceedings demand.
An established firm behind every report
Our experts are backed by the full strength of Lewis Woolcott, an established national consultancy. The firm's reputation, professional indemnity cover and ISO 9001 quality systems stand behind every report, with senior attention and competitive rates the global consultancies cannot match.
The people who lead your matter
When a matter proceeds to hearing, your position rests on the credibility of the expert in the chair. Our division is led by senior specialists with decades of project delivery behind them, supported by a wider team of quantum and delay experts — all under one roof.
David Mitchell
A quantity surveyor with more than 40 years' experience and a family background in construction consulting, David is known for approaching projects strategically and understanding every area of construction cost. He was Managing Partner of Mitchell Brandtman for over two decades and co-founded QSx Technologies and YourQS. He is a pioneer of 5D quantity surveying, past Chairperson of buildingSMART Australasia and a teaching fellow at Bond University in 5D-BIM cost modelling.
David has advised across building, civil, heavy engineering and resources: from Perth Children's Hospital, Gold Coast University Hospital and the Brisbane Airport Link tunnel to the APLNG pipelines, Wiggins Island Coal Export Terminal and the Kwinana Waste-to-Energy facility.
Chesterman J accepted Mr Mitchell's criticisms of the opposing quantum report and recognised his analysis as the basis upon which the quantum of any additional payments would be assessed.
"Mr Mitchell did perform that task and to the extent that MEPL establishes a right to additional payments their quantum will depend upon Mr Mitchell's analysis." — Chesterman J
Brad Gibbs
A practising forensic delay analyst with expert witness experience across building, infrastructure, oil & gas and renewable energy, on contracts from £3 million to €1.2 billion. Brad's engagements span the world's largest offshore windfarm, onshore wind in NSW and Queensland, hydroelectric and concentrated solar plants, substations, motorways and major mixed-use developments.
With a 30-year background in program planning and project controls, Brad prepares and defends extension of time claims and supports clients as an independent expert through adjudication, arbitration, mediation and litigation. He is fluent across the major analysis methodologies and bespoke EPC, FIDIC, NEC, JCT and trade contracts.
"Brad was able to quickly discern the critical issues of the matter and provided concise evidence-based delay and disruption analysis that was adopted by the client and supported the resolution of the dispute." — Piet van Gelder, Partner, Howes Percival LLP
