He is Chairman of the CIArb Scottish Branch and is listed on the CIArb Approved Faculty List for tutoring and examining on the CIArb Diploma (all modules for International Arbitration, domestic Arbitration and modules 1 to 3 for Construction Adjudication). Donny started his career in the construction and engineering industry at the bottom of the food chain (on the handle-end of a shovel). He progressed through work in site engineering and management for main contractors, sub-contractors and employer organisations on projects ranging from football stadia to wind tunnels, process-industry factories to bridges, and from marine piling projects to high-rise hotels (and with many others in-between). In 2001, Donny moved into consulting, initially with a large international construction consulting practice before becoming independent in 2007. He specialises, through his experience as a Chartered Construction Manager, in process and planning (including delay analysis and productivity disruption) and in standards of work and defects and, through his experience as a Chartered Quantity Surveyor, in quantum (measurement and valuation) on construction and engineering projects. Donny has conducted over 100 construction adjudications and many arbitrations. He is a member of the Dispute Resolution Board Federation. Donny's independent expert work covers valuation, delay analysis, calculating disruption/lost labour productivity, and standards of workmanship.
