With strong parent companies, TEC draws on the expertise of both Royal HaskoningDHV and Witteveen+Bos to provide a wide range of civil and structural engineering skills required for small and large underground infrastructural projects. This means all relevant technical knowledge regarding design, construction, operation and management of road, rail and utility tunnels is combined in a single organisation, allowing an integrated approach to project implementation. Adjacent services, relevant for the implementation of tunnels in their environment can be provided by the parent companies (one-stop shopping).

We use our specialist knowledge of tunnel design and construction to solve complicated underground mobility challenges; in all project phases, from initiation to operation and maintenance:

  • Tunnel construction techniques and all relevant civil engineering aspects. This includes bored, immersed and cut and cover tunnels and various special tunnel techniques such as pneumatic caissons
  • Road and tunnel safety strategies and concepts
  • Technical tunnel systems, including power supply, lighting, ventilation, drainage, fire detection and extinguishing systems
  • Tunnel traffic systems, including speed discrimination systems, height detection, matrix signs, variable message signs, mobile guard rail and barriers
  • Traffic management from local and central control centres
  • Road (alignment) design
  • Operation, management and maintenance, focusing on maximum availability of the asset in the operation phase
