Errors have become an innate feature of the design process in construction and engineering (Love et al., 2009). Errors occur due to physiological and psychological limitations of humans. It is a matter of contention whether individuals can justifiably be blamed for all errors, as making mistakes is an innate characteristic of human nature (Reason, 1990). Human errors occur for various reasons and therefore different actions are needed to prevent or avoid the different sorts of error experienced in construction and engineering facilities. Regardless of the skill level, experience or training that individuals possess, errors and omissions may be made at any time. According to Reason and Hobbs (2003) errors involve a deviation of some kind, whether a departure from an intended course of action, departure from a path of actions planned toward a desired goal or a deviation from the appropriate behavior at work. An error can arise due a mistake, non-compliance, slips or lapses. Even the most qualified and highly competent individual can make a mistake or mishap. Indeed, Reason (2000) contends that it is often the best individuals that commit mistakes with the worst consequences. The general understanding, however, of the adverse effects of errors is better understood than the potential benefits that can be acquired through learning to prevent their occurrence (van Dyck et al., 2005). Lessons that can be learnt from accidents, crises or events, have been identified as an integral component of an organization’s ability to learn (Choularton, 2001).
