Abstract

The construction industry seems to have settled down to a level of inefficiency saddled with a culture of handing over buildings with defects with mechanisms for dealing with patent, latent, serial and other defects. While it is important to understand direct and root causes of defects, the key to success lies in implementing strategic solutions in an environment where subcontracting is rampant: Accordingly, this study takes a trade-based risk management approach to identify problematic trades by undertaking a risk assessment. While Queensland Building Construction Commission’s top ten defects provide an indication of what such trades may be, this study argues that it fails to provide a comprehensive overview of the defects regime related to single and two-storey houses, therefore, this study focusses on all 34 trades that requires a license to practice. Trades that are high risk, moderately high risk, and moderately risky have been identified through an on-line questionnaire survey sent to approximately 500 respondents which seek information on the likelihood and the impact of defects for each licensed trade including reasons for high risks. The scores received are translated to risk levels and multiplied together to arrive an overall risk score which is classified into high, moderate, and low risk using a risk classification matrix. Accordingly, 14 problematic trades have been identified with Waterproofing being the riskiest trade followed by Swimming Pool Construction and Concreting. The study emphasises the value of this approach to practitioners and regulators to develop strategies for ensuring buildings are defect free.
