Existing Art Deco building structurally retrofitted internally to accommodate the new mechanical and electrical services upgrade for new laboratories, lecture theatres, teaching spaces and library after a back to base strip out. Works included the demolition of the existing flues, new substation, medical gasses installation and chemical laboratories for research. New fume cupboards were installed including new ducts exiting the building through new penetrations and terminating at a new plant platform. Coordinating the demolition to enable new services upgrades required detailed planning and management to achieve minimal disruptions to live lecture theatres. The project involved multiple staging over three years while working in a live operating environment.
