Tunnel Cost-Estimating Methods.
Abstract
The Office, Chief of Engineers (OCE), U. S. Army recognized the need for improving capabilities for estimating tunnel costs, improving support design, and overall, making tunnels and cavities more cost competitive with above ground alternatives. Thus, the OCE requested that the U. S. Army Engineer Waterways Experiment Station (WES) conduct a study to develop and verify reliable methods for estimating costs of tunnel construction and establish improved (more cost-effective) methods for design of tunnel and cavity support systems. This report describes an investigation of various tunnel construction cost-estimating techniques. Manual and computer methods are described and compared, important elements of tunnel construction are discussed, and an evaluation is made of the most promising computer cost model, using case histories of three completed tunnels for which good documentation was available. The cost-estimating methods described herein can be used to develop more comprehensive and accurate estimates for tunneling.
