Measuring and monitoring

Monitoring is increasingly common in construction projects. However, measurement data do not always provide the desired information. The reason is that the monitoring strategy is often insufficiently thought through beforehand.

Professionalising Water Works Inspections Programme (2017)

The programme Professionalising Inspection Flood Defences 2.0 (PIW2.0) of STOWA and Rijkswaterstaat has the ambition to further professionalise the inspections of flood defences. After the previous phases focused on substantive improvement and professionalisation of the inspection process, PIW2.0 establishes the relationship with the adjacent management cycle, review cycle and implementation at water managers.

Monitoring in practice (2016)

Considerable efforts were made within CUR/COB in the period 2009-2015 to establish clear guidelines and recommendations for the design and monitoring of construction pits in urban environments. This report discusses in detail the monitoring philosophy, the resulting monitoring strategy and the technical and process details for three practice projects.

Dike inspection with drones (2015)

An exploration of the potential for using drones in the inspection and management of flood defences. This report was written as part of the Professionalising Inspections of Flood Defences (PIW) programme.

Quality control of in-ground elements (2015)

This Geo-Impulse project focused on specific problems around diaphragm walls and on the integrity of other soil-formed elements. Weaknesses of soil-formed diaphragm walls are often difficult to detect. Crosshole sonic logging, a technique based on measuring sound waves, proved to be a good solution for this.

Geo-Impuls: Observational Method (2015)

The Observational Method is a design method described in the Eurocode to use intensive monitoring to collect information about the behaviour of a structure and use it in decision-making processes about the execution of the work. The Geo-Impulse project 'Observational Method' demonstrates through example projects how this method can contribute to reducing failure costs and optimising a project. A corresponding guide on the Observational Method was published in 2015.

Directive on measuring and monitoring construction pits (2010)

Monitoring and quality control are indispensable tools in construction pits in the design and execution phase. This Curnet guideline aims to optimise the use of measurement and monitoring in construction pits, and thus improve risk management. To make full use of the added value of measuring and monitoring, this publication pays particular attention to incorporating monitoring in the construction process and in the project organisation. Appointing a monitoring coordinator is part of this. The step-by-step plan in this publication can be used to determine the monitoring required, based on the situation and project-specific risks.

Diaphragm wall handbook (2010)

This CUR handbook contains a comprehensive description of the design and execution process of diaphragm walls. The handbook pays attention to the important connection between design and execution. Quality control during and after execution, as well as monitoring are also described. Lessons learned from previous damage cases are also discussed; these experiences were used to identify critical components in design and execution.

Delft Cluster: Rapid pile testing (2010)

This research into the optimisation of pile foundations called, among other things, for better models for calculating the bearing capacity of piles and for fast and cheap methods for testing the bearing capacity of installed piles, such as quasi-static techniques.

Symposium Leak Management (2004)

On 30 March 2004, KIVI-NIRIA geotechnics, the CDE and Deltares (then GeoDelft) organised the Leak Management symposium. Very different aspects of leakage of underground structures from both the civil engineering and environmental fields were discussed. The variety of speakers was as diverse as the range of topics. Speakers from TU Delft, Gemeente Utrecht, Volker Wessels Stevin and GeoDelft addressed topics such as the importance of good design, practical cases, implementation aspects, detection techniques and repair methods. The presentations, articles and accompanying summaries of the symposium can be found here.
