09.00	Session G. Some of the geotechnical questions that may lead to the use of instrumentation: John Dunnicliff, UK Braced excavations Embankments on soft ground Embankment dams Excavated and natural slopes Underground excavations Driven piles.
10.00	Session H. Data handling: data bases, visualization and reports: Andres Thorarinsson (Vista Engineering) For many, the real work of data logger systems really starts when the sensors, data loggers, communications and data collection have been installed and are up and running. But for others, it is now that the real work starts, with data handling, validation, alarming, the interpretation of data and decision making, routine checking if all equipment is in good working order as well as all kind of reporting, including monthly reports. Then, there is controlled access to data and setup's, modifications of layouts, texts and units. This work is forever, and it is therefore necessary that those involved in data handling have good overview of what might be useful.  In this lecture, some vital phases are explained with real-world examples.
10.40	Questions and discussions
10.45	Break
11.00	Session I. Instrumentation for monitoring the performance of infrastructure slopes (embankments and cuttings): 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.

18.00	Adjourn

Thursday 23 April 2009
09.00	Session L. The Barcelona Breakwater and general lessons for the offshore instrumentation: James Strout, Norwegian Geotechnical Institute, Norway The Barcelona breakwater is a combination of 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. In general, subsea instrumentation often serves the same functional purposes as onshore instrumentation. Some of the challenges of moving from land to subsea are dealt with.
09.45	Session M. New measurement technology for dike monitoring: André Koelewijn, Deltares, the Netherlands 27 September 16.02 uur at Booneschans in the North of the Netherlands a dike, 6 meters high and 100 meters wide, collapsed. The dike failure was monitored by numerous sensors and cameras. There was no real danger to the public since this was a research project that aims to increase the safety of the Netherlands against flooding. The testdike was instrumented with innovative measurement systems supplied and installed by a large number of participating companies. General question: can these instruments predict dike failure in advance? The presentation will deal with the setup of the experiment and the results of the innovative measurement systems.	www.ijkdijk.nl

14.10	Session P. 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.
14.55	Questions and discussions
15.05	Break
15.20	Session Q. Deformations of highspeed railway line (HSL South) in the Netherlands: Antoine Feddema, Deltares, the Netherlands North of the town of Leiderdorp the highspeed railway line 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 at some locations the strict horizontal dispacement tolerances for the railway could hardly be met. 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.
16.00	Session R. High precision geodetic monitoring: Ulrich Völter, Intermetric GmbH, 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.
