The defense, aviation, and oil industries used various ILS techniques, such as failure reporting, analysis, and corrective action system (FRACAS), failure modes, effects, and criticality analysis (FMECA), reliability centered maintenance (RCM), level of repair analysis (LORA), and life-cycle costing (LCC). ILS is an engineering and management tool that when used correctly ensures that the owner and user will receive a project that meet their performance and support requirements (El-Haram & Horner, 2002). The construction industry, however, has not fully embraced the ILS techniques. As a result, the industry has underperformed for many years, preferring cost approaches that do not account for LCC (John, Clements-Croome, Fairey, and Loy, 2005).
