John McGill is a Managing Director in the FTI Consulting Forensic and Litigation Consulting practice.  He has worked in the construction industry for over thirty years, the first ten of which was spent gaining experience with major construction and engineering contractors.

Following nine subsequent years in construction contracts consultancy, during which time he was called to the Bar of England and Wales (July 1992), Mr. McGill was appointed as Director of Legal and Commercial Affairs of a national trade association in 1997 involved in the engineering construction sector of the industry.  His role included providing advice and guidance on all legal aspects of construction contracts and contract management to the member contractor organisations, representing their interests to government and other bodies, and drafting codes of practice, policy statements and member publications to help improve industry competitiveness.  He also provided training for management staff and professionals within the industry.

Since joining FTI Consulting Mr. McGill has gained further valuable insight through extensive procurement and contract management advisory role instructions particularly for project funding bodies and contracting organisations where performance, financial and contractual matters required investigation, clarification and recommendatory guidance.  Mr. McGill has also been engaged in advising on a wide span of dispute resolution matters and in claim preparation and negotiation, advocacy and mediation references both on behalf of employer/owner and contractor parties, including acting in numerous adjudication proceedings.  He has been instructed as an expert witness on quantum and quantity surveying matters, having gained experience as an expert witness assistant on similar issues.  Through his experience, Mr. McGill has developed honed communication skills and is used to presenting with clarity, typically detailed information in succinct form whether by written or oral means in order to meet the client’s objectives.
