Abstract

Large and complex underground projects comprise of many excavation parts and require a relatively long construction period. Design and construction of such projects need a thorough analysis of many information including borehole logs, cycle time, requirements of equipments, the arrangement of multiple excavation faces along the project’ s time-line, and the arrangement of equipment allocation among multiple faces. The result of this analysis should yield an optimum construction time and the required strategies to manage this period. This paper explains some methods to conduct such analyses to evaluate a geological model, the details of a cycle time, the strategy to evaluate the total construction time and its optimum value, and the strategy to optimize the equipment allocation. The results of these methods are beneficial for the projects’ engineers to reach to a better evaluation in the design phase of a project (e. g. bidding time) and to plan a better construction management strategy during the construction phase.
