This report focuses upon the transportation construction industry in Japan. Chapters 2 and 3 each address organizational and institutional factors in the Japanese construction industry. Chapter 2 discusses the structure of the industry and characteristics of Japanese construction administration and management. Chapter 3 gives more specific information on the role of research and education in Japanese construction. Chapters 4 through 7 each examine a specific technological area of interest to transportation construction, especially for projects involving excavation and tunneling. Chapter 4 deals with tunneling technology for shallow urban transit tunnels. Chapter 5 introduces methods for excavation and construction of underground stations and cut-and-cover methods that help reduce disruption to the urban environment. Chapter 6 describes some Japanese improvements on the underwater tube-tunnel concept that has been employed on rapid transit projects in San Francisco and Washington. Finally, Chapter 7 gives an overview of two new inter-urban rail tunnel projects for the high-speed Shinkansen of two new inter-urban rail tunnel projects for the high-speed Shinkansen ("Bullet Train") line. These include the record-breaking Seikan undersea tunnel for the Hokkaido line, andd the Nakayama tunnel on the Joetsu line. Both tunnels are setting new world standards for coping with semingly impossible topographic and geologic conditions. (Author)
