High Speed Ground Transportation. Tunnel Design and Cost Data
Five important components of costs of tunneling, shafting and construction of terminals were identified. These cost components significant to tunneling, that is, those that account individually for more than approximately 5 percent of the total cost, are: (1) Excavation; (2) Muck loading, transport and disposal; (3) Tunnel supports; (4) Tunnel lining; and (5) Interface load supports. Similar cost components of shafting and terminal construction were identified. Five characteristics of the HSGT system and three groups of geologic conditions of the site that materially affect the cost components of tunneling, shafting and terminal construction were identified. These significant HSGT characteristics and site conditions are: (1) Tunnel and shaft diameter; (2) Terminal size; (3) Depth; (4) Shaft spacing; (5) Interface loads; and (6) Rock types grouped according to their excavation, supporting and water transmission characteristics. The rock types were delineated according to these groupings on maps of the project area. (Author)
