The management of error in construction projects
The 'defects problem' has demanded considerable attention in recent years, with much emphasis given to the technical causes of failure. This research project examines the problem from a different point of view - that of human error. Taking as a starting point, technical publications in the construction industry, the research reviews human error literature from a variety of industries and perspectives and synthesises a model of error causation covering organisations in a construction project context. This model is then progressively tested in four studies, a general preliminary survey and three more detailed studies of house-building. Conclusions support the view that errors leading to failure in complex socio-technical systems often exhibit systems characteristics and involve the whole managerial structure. An improved model is proposed, which emphasises the importance of both project and general management errors.
