I'm not a Planner but have always prepared programmes as part of my role as QS, Commercial Manager and Project Manager.
Since specialising in dispute resolution I have become familiar with problems of delay and disruption and now work exclusively as a Delay Expert.
My experience is in fast-track projects, fit-out, refurbisment, high-rise, industrial, M&E, district heating, power generation, commericial - well.... everything except civils, marine and petro-chem really.
