Abstract:
Geotechnical, structural and environmental monitoring is becoming a standard requirement on construction, civil engineering and mining projects. With the amount of data to be handled, the quantity of stakeholders and the number of projects increasing very rapidly, the quality and usefulness of monitoring can sometimes be compromised. This paper reflects on the key factors influencing the success of a monitoring project. It aims at helping to convince decision makers to make the right choices when dealing with monitoring. The first steps in a monitoring program are design and specification. The authors recommend that the design is carefully thought through, on a site per site and risk per risk basis, so that the correct number and type of instruments are specified. Defining and reserving a sufficient budget for the monitoring is paramount. Unfortunately, too often an inadequate budget leads to money being spent vainly on useless monitoring. The choice of the company in charge of the monitoring must never be based solely on direct cost. This is unfortunately often the case for private contracts. On public contracts, however, there is a trend towards trying to apply the best for purpose rule, even if the decision process remains a complex task. During monitoring project implementation, the engineer or the client should ensure that they have the will, the power, and the tools to demand high quality data. This can only be achieved if the monitoring rules are previously planned and well defined at the specification stage. The experience and dedication of the monitoring team has a huge impact on data quality. Instrument installation and readings must be carried out according to predefined methods and quality control procedures. Both manual and automatic instrumentation must be implemented, their ratio depending on the site specific characteristics. Finally, the monitoring tools usually contained within the monitoring database software must bring added value to help the stakeholders understand the state of their project and risks involved. This includes data fusion (mixing data of different types), alarm management, dashboard and weather map presentations and a journal of events and reporting tools.
