The basis of design of temporary support to a 40 metre deep vertical rock excavation in a dense urban environment is described. In particular the significance of water pressures on the design are discussed and methods of modifying traditional assumptions, by taking account of hydrogeological features, are proposed. Results of monitoring of the actual water pressures during excavation are given and compared with the predicted values.
