Paul Waldeck B.Eng.(Hons.) C.Eng. MI.C.E. M.I.Struct.E. M.A.S.H.R.A.E.

Chief Technical Officer – Executive Director

Paul is a Chartered Engineer with 35 years of experience in design, construction, maintenance and refurbishment of safety-critical environments and facilities. He has been involved and led some of the most extensive capital programmes in the built environment; worked in nuclear, chemicals, food production, pharmaceuticals, laboratories, health, transport, and all the conventional sectors of the built environment in his career too.
