- Abstract:
Loss of productivity is a contentious issue that has a profound impact on modern construction, yet existing literature provides no quantitative, data-driven method to compare the productivity of different construction projects or to assess their vulnerability to productivity loss. A new mathematically derived metric, called the “Risk of Productivity Loss (RPL)” score, provides such a method. RPL is a function of multiple distinct productivity factors. The RPL score is developed from a dataset of 166 electrical and mechanical projects, which collectively amount to 7.2 million labour hours. This large sample size makes the RPL score a reliable productivity benchmark for the electrical and mechanical construction industries due to their labour-intensive nature. The higher the RPL score, the higher the risk that a given project will suffer from productivity losses. To supplement the mathematical formula presented, objective data-based weights for multiple key productivity factors have been identified, reducing the subjectivity that affects many of the existing weighting assessment methods. RPL provides the industry with a single metric that allows tracking and assessment of productivity for multiple projects at a time so that a contractor may assess the successful reduction of productivity risk factors within the projects in their company.
