The Netherlands is becoming increasingly full. It is getting more difficult to accommodate the wishes of politicians and local residents in newly built infrastructure. The result is a growing demand for underground solutions for traffic and utilities. For reliability reasons and for the quality of the surroundings, too, underground construction is increasingly the preferred option for infrastructural works. Witteveen+Bos has contributed significantly to this development, not least through its involvement in virtually all recently-bored tunnels in the Netherlands.
An important consideration when building structures below ground is the extent to which construction, groundwater and subsoil will influence each other. Another matter that needs a lot of attention is care for vulnerable surroundings and urban complexity. Witteveen+Bos sets the pace when it comes to underground construction and has extensive experience in carrying out underground construction projects, notably under difficult circumstances. We have in-house the knowledge and people necessary to reduce complex issues to their essence and carry out projects successfully – regardless of whether the project concerns a planning study or detailed design, a modestly sized project or a mega-project in intricate surroundings.
Our competence in this challenging domain is reflected by our ever-expanding expertise in mastering tunnel-boring techniques, managing subsidence risks and establishing contracts. A project that pooled all this knowledge, was the Hubertus Tunnel in The Hague. This 1500 metre road tunnel was the first in the Netherlands to be bored below existing buildings. Witteveen+Bos’s expertise was instrumental in building the two-tube tunnel quickly and without problem.
