TUNNEL COST MODEL, USER'S MANUAL, VERSION 2- TUNNEL CONSTRUCTION REPORT NO. 7

The Tunnel Cost Model is a simulation model of tunnel construction which addresses problems of cost estimating and project scheduling under conditions of risk or uncertainty. The model develops the concept of underground construction as a production process, and to this concept applies procedures drawn from current estimating practices of contractors, owners, and designers. Its main advantages are its flexibility in adapting to diverse needs among users and to various types of underground projects; its ability to match speed with a very high level of detail and accuracy; and its explicit treatment of many major sources of uncertainty in project planning, analysis and control. Any underground structure or complex of structures may be considered, ranging from shafts, tunnels, or adits to networks or systems of tunnels to large underground caverns. This user's manual is designed to facilitate the user in preparing input to the Tunnel Cost Model. It is assumed that the user has a general knowledge of using computer-programs for solving problems. This manual describes in detail the commands, sets of commands, and general input necessary to run the model. Also provided is information necessary for installing the TCM. Wherever possible, the commands have been described in separate sections so that specific questions or problems can be easily addressed. The order that the input commands are presented in is the most likely order that they will be used by the model.
