Failures arise because of deficiencies in design and detailing, or the inappropriate specification of substandard materials. Deficiencies that manifest themselves as errors and result in a failure may occur because of lapses, slips, mistakes, and omissions during the design process, or downstream in the construction and/or maintenance phases of a constructed facility’s life cycle. Design errors can be significantly reduced when design checks are undertaken prior to construction commencing. Schneider (1997) has revealed that through rigorous design checks 32% of errors can be detected. In addition, if an independent third party is used then as much as 55% of design errors could be accounted for. While design checks and verifications are useful for identifying errors their usefulness is somewhat limited if lessons are not learnt from previous projects and appropriate training and skill development is put in place for individuals and teams.
