THE KEY ROLE OF MONITORING IN CONTROLLING THE CONSTRUCTION OF THE NEW JUBILEE LINE BETWEEN WATERLOO AND WESTMINSTER, LONDON

Necessary for the success of Contract 102 of the Jubilee Line Extension Project (JLEP) was the detailed analysis of the impact of the construction process on the surrounding ground, structures, and tunnels. Because construction would pass under or alongside historic buildings, stringent limits were imposed on ground and structure movements. A comprehensive monitoring system was required, comprising a wide variety of instruments linked to a geotechnical database. The result was Geosys, a Windows-based monitoring system developed in-house that could handle data from various instruments on site in real time. This paper describes the data handling and processing capabilities of Geosys. The subsequent geotechnical benefits to the contract, through the application of high quality processed monitoring data to the control of the ground movements and the construction works, are discussed.
