AbstractCivil engineers have struggled to prepare budget estimates for transit terminal projects that include recent advances in safety and risk analysis during construction. They question whether their standard cost estimates are suitable for an expansion project that by necessity imposes severe restrictions. Safe transit projects are crucial in the development and growth of economies. Safe work zones require proper illumination to insure good visibility of workers and their equipment. Identifying and understanding the factors that influence the cost of a transit expansion project is of great importance throughout its development. This case study builds on studies of many projects of varied scope. The variables are many, and often the constraints do not match the activity under consideration. This model’s structure and principles are targeted at the expansion of an existing transit hub that is active and necessary for the economic health of a community. The model that has been developed in this case study provides an overview of the project’s anticipated costs. The objective of the case study is to present a model that may be utilized to prepare a budget estimate for the expansion of an active bus and rail terminal that will grow through periodic updates to produce a final cost. The objective of this research is to review the risk of different variables that are predictive of superior safety performance and present a revised framework that satisfies the needs of owners to measure the culture of safety and risk using a practical model.
