| Abstract | The main objective of this study was to develop a model for estimating the cost of subway station and tunnel construction. This report describes a cost estimating methodology for subway tunnels that can be used by planners, designers, owners, and government agencies interested in evaluating a realistic range, within which the actual bid would fall, for the cost of subway tunnels. The study approach was to analyze the actual subway contractors' techniques and try to formalize their cost estimating processes into a realistic model. Extensive interviews were conducted with subway tunnel contractors and designers to identify the basic framework for estimating costs. In this report, a hierarchical cost estimating technique is developed whereby project-specific and contractor-specific factors are identified and structured, i.e., typical advance rates are developed for a variety of geological and geometrical conditions: crew sizes (by skill) for varying geological conditions and construction methods; type and size of equipment and their associated writeoff values; type of materials; contractor overhead, taxes, interest costs, etc. A database of actual equipment, labor, materials, and lump sum costs has been compiled and may be updated as changes occur. |
