MATERIALS HANDLING FOR URBAN TUNNELING IN ROCK
An examination of prior forecasts of tunnel construction provides an estimate of 2.4 million feet of rock tunnel to be constructed during the 1976-2000 period. Tunnel projects for the near term (1980+) and far term (1990+) periods are defined for study. The flow and characteristics of materials handled are defined for the tunnel projects. The state-of-the-art and status of R&D programs for materials handling are reviewed. Based on extensive interviews with representatives of tunnel contractors, equipment manufacturers, government agencies, and consultants, the application of various methods of material handling to tunneling is discussed, including conventional rail haulage, crane and hoist lifting, and horizontal transport and lifting by hydraulic and pneumatic pipeline and by conveyor. Total job cost estimates using these modes of material transport are obtained (with material handling costs isolated) by modification of an estimating technique used for preparing contractor bid estimates. A comparison of the results indicates that major cost savings through substitution of alternative material handling modes should not be anticipated. R&D program elements are recommended to assure that material transport will not become the limiting factor as the rate of tunnel excavation increases in future years.
