Ten years have passed since in 1997 for the first time construction of bored tunnels in the Netherlands soft soil was undertaken. Before that date essentially only immersed tunnels and cut-and-cover tunnels were constructed in the Netherlands. The first two bored tunnels were Pilot Projects, the 2nd Heinenoord tunnel and the Botlek Rail tunnel....

Transitions between railway track on embankments or natural ground and fixed structures such as bridges and culverts often require substantial additional maintenance to preserve line, level and ride quality. This extra maintenance not only increases costs but also causes delays. Despite its importance for railway infrastructure owners, the...

Modern large cities are characterized by a high building concentration, little aeration and lack of green spaces. Such characteristics create an urban climate which is different from the climate outside of cities. An example of an urban climate effect is the so-called Urban Heat Island: cities tend to be warmer than the surrounding rural areas....

Urban areas are complicated due to the mix of man-made features and natural features. A higher level of structural information plays an important role in land cover/use classification of urban areas. Additional spatial indicators have to be extracted based on structural analysis in order to understand and identify spatial patterns or the spatial...

There is a growing pressure on urban public transport companies and authorities to improve efficiency, stemming from reduced budgets, political expectations and competition between operators. In order to find inefficiencies, bottlenecks and potentials in the public transport service, it is useful to learn from recorded operational data. We first...

Prediction of train positions in time and space is required for traffic control and passenger information. However, in practice only the last measured train delays are known and dispatchers must predict the arrival times of trains without adequate computer support. This paper presents a real-time tool for continuous online prediction of train...

Since the initiation of environmental legislation, monitoring campaigns have been done to estimate the characteristic pollutant concentrations of combined sewer overflow water. Such local campaigns are expensive due to the large number of events which should ideally be followed. This study focused on whether available concentration ranges from...

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,...

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...

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...

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...

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...

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...

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...

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 ...

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...

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...
