Increasing pressure for preservation of surface environments in urban and rural areas is forcing the utilization of subsurface space for transportation and other purposes. Technological developments, such as in rock mechanics and in tunneling machines, will make possible the rapid and successful utilization of subsurface space. For several years it has been recognized that contracting practices in the U.S. are inadequate for even past methods and constitute a serious barrier to application of new technology and to economical development of underground space. This survey of U.S. and foreign underground construction results gives 17 recommendations for improving contracting practices.
