Relationship between project performance and accidents

This paper explores relationships between project performance characteristics and the timing and frequency of construction accidents. Accident data (e.g., first aid case rate and recordable rate) were superimposed over standard project control s-curves related to design, procurement, and construction activities (e.g., % design complete and % actual construction cost) on a project-by-project basis and trends were observed. Relevant data were collected for seventeen industrial projects from the start of detailed design to the end of construction. General information associated with the projects (e.g., size and type of contracting approach) was also obtained. Results show that projects that were consistently behind schedule and over budget experienced a greater occurrence of recordable accidents. Knowing the relationships between project control s-curve profiles and safety performance is beneficial for safety representatives as it will give them an advanced warning of the representatives can better focus their worker safety programs during the different phases of construction and this can lead to fewer accidents. Limitations and recommendations are also included.
