Kim S. Elliott is a consultant to the precast industry in the UK and Malaysia. He was Senior Lecturer in the School of Civil Engineering at Nottingham University from 1987-2010, and was formerly at Trent Concrete Structures Ltd., one of the UK's leading precast concrete manufacturers. An active researcher into the behaviour of precast concrete structures, he has published extensively on the subject. He is a member of FIB Commission on Prefabrication. Zuhairi Abd. Hamid is Executive Director of the Construction Research Institute of Malaysia (CREAM). With more than 32 years of experience in the construction industry, his research interests and expertise falls within the area of Strategic Management of IT in Construction, Strategic Facilities Management in the Health Sector, Structural dynamics (wind engineering and earthquake engineering), prefabricated building construction and the Open Building System.
