The site investigation gave a generally accurate picture of the geology of the site, accurately predicting t h e location of ma~cr faults an~ providing most of the ground informtion required for tunnelling. However, the rock was found to contain more Joints than was indicated by the site investigation, no doubt because of the difficulty of intercepting steeply inclined Joints with a vertical borehole.

The 1~lhniques considered include groutir~ in soil and rock, ~ freezing, cast in situ walls, prefabricated walls, secant piles, slurry shield tunnelling and t h e New Austrian tunnelling method applied to soft grourd coniltions. The economics of umdergroumd construction and the orgsmlsation amd o~erations of several European metro authorities are also discussed. Turmelling practice in the U.K. is studied and used as the basis for a discussion of apporbiomment of risk and the resolution of contract disagreements.
