Most construction projects are still performed by using long established and somewhat antiquated methods. The industry is characterized by high levels of inefficiency and waste (as much as 30%) that inflate the cost of construction and cause many delays, and often unsafe practices that result in disproportionately high worker injury rates. The application of IE techniques and the active inclusion of IEs in the construction environment will be presented. Practical examples will be discussed relating to: Efficiency and productivity measurement and improvement - time study, methods engineering, job design, layout design are adapted to the construction environment Human factors - application of ergonomics increases efficiency and minimizes on the job injuries and worker health impacts. Safety engineering also reduces worker stress and resulting lost work days. System and integration - planning, resource allocation and scheduling are integrated to overcome the negative impacts of fragmentation. Operations research - supply chain management, work crew scheduling, transportation etc. are optimized through OR techniques.
