13.30	Session C. Vibrating wire instruments: Tony Simmonds, Geokon, USA A brief overview of vibrating wire technology including some of the special "one-off" sensors and the very demanding applications for which they were intended. Instrument checks, installation procedures, reading and troubleshooting - using a VW Piezometer, VW Tiltmeter and VW Crackmeter as examples, including a live demonstration.
14.10	Session D. Instrumentation for monitoring infrastructure slopes: Andrew Ridley, Geotechnical Observations, UK The UK’s aging infrastructure is under increasing pressure. None more so than the large number of embankments and cuttings that carry roads, railways and canals around the country. The slopes on many of these earth structures are active. Displacements, albeit small in the short term, can result in serviceability problems and can eventually lead to stability problems. This presentation will show the results from recent investigations of this problem and will use these results to make recommendations on appropriate types of instrumentation to be used.

10.00	Session H. Relationship between monitoring, risk management and the construction process: Martin van der Meer and Rob van der Salm, Fugro, the Netherlands As with any programme, monitoring programmes should be driven by clear objectives. This session considers the monitoring objectives from a risk management perspective, in which the ultimate goal of monitoring is to facilitate the control of risk. Risk can only be controlled effectively if it is clear who is responsible for which risks. To be effective, risk allocation should be made explicit and measurable. The Geotechnical Baseline Report is a concept that can be applied to geotechnical risk allocation. Using a Geotechnical Baseline Report, each party can ascertain its responsibility for geotechnical risks. It serves as a basis for any risk mitigation measures, where monitoring is often a major element. Topics: Monitoring and risk Why risk allocation? How to allocate monitoring risk? Geotechnical Baseline Reports in monitoring practice Setting up a risk driven monitoring programme.
10.40	Break
10.55	Session I. Monitoring Amsterdam central station during construction of a new metro tunnel: Bauke Schat, Arcadis, the Netherlands The municipality of Amsterdam is preparing a new metro line from the Northern part of the town to the Southern, called the North/South line. The metro line crosses the main building and all tracks of Amsterdam central station about 15 meters below surface level. The task of the contractor is to build a new tunnel under the historical masonry building and the railroad tracks. During the construction process structural damage to these structures should be avoided. Monitoring is an important tool for both the principal and the contractor to manage the construction process.
11.40	Session J. Application of instrumentation offshore: James Strout, Norwegian Geotechnical Institute, Norway In general, subsea instrumentation often serves the same functional purposes as onshore instrumentation. However, the challenges of moving from land to subsea are not trivial. The focus of this topic will be the special considerations required for subsea and underwater instrumentation. Offshore infrastructure: platforms, vessels, ROVs and the working environment Harsh environment: pressure, corrosion, mechanical protection, barrier philosophy Redundancy and reliability, safety requirements in the offshore industry Components: cabling, connectors, pressure containers, power supply, communication Examples of solutions implemented in key offshore projects.

Thursday 17 January 2008
09.00	Session L. The Barcelona Breakwater: James Strout, Norwegian Geotechnical Institute, Norway The Barcelona breakwater is a combination rubble fill/caisson breakwater constructed on soft harbor sediments in an active port area. A critical issue in the construction phasing of the project was the degree of consolidation of the sediments. The encountered problems and solutions implemented for this project are presented.

13.30	Session P. High precision geodetic monitoring: Ulrich Völter, Intermetric, Germany Construction projects always have an impact on the environment. Nowadays this impact can be quantified exactly and online by installing an appropriate geomonitoring system. This can reduce overall project risks significantly because precautionary provisions can be implemented immediately when needed. The key to this approach is a high precision geodetic geomonitoring system. This lecture will show recent advancements in geodetical geomonitoring and a number of current projects.
14.00	Session Q. Monitoring based remedial measures on the highspeed railway track: Antoine Feddema, GeoDelft, the Netherlands North of the town of Leiderdorp the highspeed railway HSL South runs parallel to the A4 motorway through an area with very soft soils. During the design of this part of the railway it was already concluded that the strict horizontal dispacement tolerances for the railway could hardly be met at some locations. Therefore an intensive monitoring programme was executed. Based on the results after the first year of monitoring remedial measures combined with additional monitoring were necessary.
14.45	Questions and discussions
15.00	Break
15.15	Session R. Monitoring the highest dam in the world, Patrice Droz, Stucky, Switzerland Lake Sarez in Tajikistan was formed in 1911 when a massive earthquake-triggered landslide buried the village of Usoy under a 650 m high obstruction which dammed the Murghab River. Due to its outstanding mass, the level of knowledge of the Usoy dam is reduced to hypothesis based on observations and analysis of few parameters. A risk analysis approach has been used to define a modern monitoring system, coupled with an early warning system.
