The 189.50 m long Bobova tunnel constructed in 2005 is located on the D404 state highway and passes under a part of the Vežica – Sušak town area in Rijeka. The overburden above the tunnel pipe is between 2 m to 18 m thick. The rock mass along the tunnel route is made up of karst deposits (transient carbonate breccia, dolomite and limestone...

Dams and dikes are both water-retaining earth embankments. These are vulnerable to internal erosion but specific differences lead to varying vulnerabilities to different types of internal erosion: • Dams are usually zoned, with potential filtering capability to arrest piping if it is initiated, while dikes are more commonly unzoned and incapable...

Energy renovations offer unique opportunities to increase the energy efficiency of the built environment and for the existing housing stock, they are the most important solution. Usually, energy savings are based on modelling calculations. However, recent research has shown that the predicted energy consumption differs largely from the actual...

Ecosystems are providing a stream of essential goods and services for the national socio-economic prosperity and welfare; paradoxically, these services have to suffer a high vulnerability against the increasingly uncontrolled use of human beings. World-wide researchers and authorities are working to ensure the sustainability of nature; and...

Designing challenges engineers to develop both economically attractive and safe designs. This might seem a paradox, but with the application of the observational method, wherein safety is checked by real-time monitoring, economic design and safety are united. The observational method is recently successfully applied in the Netherlands during the...

A new lifting bridge is being constructed crossing the river Oude Maas in the Rotterdam harbour area in the Netherlands. Since foundation deformations of the main piers have a large influence on the performance of the superstructure, extensive deformation analyses have been performed during the design phase. In order to minimise the risks and...

The application of the Observational Method can contribute to an economic construction process and effective geotechnical risk management. Current project management practices and control of construction works lead to unfavourable conditions of its application. Throughout the realization of infrastructure, understanding of project risks and...

The A2 tunnel in Maastricht has been built within a dry building pit with a maximum depth of 22 meters with sheet pile walls, suspended in a cement bentonite trench supported by struts at 2 to 4 levels. Dewatering is done by deepwells. The excavation reaches into Limestone layers so the maximum mobilized passive resistance of the sheet pile wall...

In the preparation and construction stages of the underground car park beneath Kruisplein with diaphragm walls, risk management played an important role. After a description of the structure and the construction, the preventive measures that were invented and carried out are summarised. These relate to the organisation of the project ...

The present work shows and discusses the GBInSAR measurements for the Ingelsberg area, where one of the most dangerous landslide of Salzburg region is located (Bad Hofgastein – Austria). It is a rockfall developing on an area of about 40000 m2 which is characterized by the outcropping of anti-dip stratified green and calc-mica schists. The...

Ground, building and utility deformation monitoring is a well-accepted and required practice for underground construction works in urban environments. The availability of real-time monitoring data during construction allows stakeholders to stay ahead of potential problems, to make decisions prior to damage occurrence, and ultimately to reduce...

Looking back over a period of 10 years of underground works, geotechnical risk management has matured and has definitively contributed to the success of geotechnical projects in Rotterdam. But, what exactly was it that made geotechnical risk management successful? Looking back, and analysing the process, 8 habits of the (geotechnical) risk...

Recent research has shown large differences between the expected and the actual energy consumption in buildings. The differences have been attributed partially, to the assumptions made during the design phase of buildings when simulation methods are employed. More accurate occupancy profiles on building operation could help to carry out more...

In 2002 EU adopted the Energy Performance of Buildings directive which was subsequently adopted by the member states. However, more than a decade later, no national registers of certificates have become available publicly or to research institutions in order to give feedback on the introduced regulation. By exploring the 4 million certificates...

We investigate potential benefits of measuring the vertical electric field component in addition to the routinely measured horizontal electric field components in onshore time-lapse controlled-source electromagnetics. Synthetic electromagnetic data based on a model of the Schoonebeek onshore oil field are used. We confirm that the vertical...

New planning approaches put new requirements on evaluation. A recent innovation in the water domain is adaptive delta management (ADM). ADM supports long-term planning in the face of uncertainty. This paper discusses the main considerations for the design of an evaluation system for ADM, departing from literature on evaluation systems, adaptive...

Hydraulic timber structures such as mooring poles, fenders, lock gates and jetties are widely-used in inner and sea harbours all over the world. In general these structures give satisfactory performance with regard to the technical requirements. Because of the harsh exposure conditions such as brackish and contaminated water, drying-out,...
