TEC is a permanent partnership in the field of tunnel and underground works projects between two leading Dutch, internationally operating, engineering consultants Royal HaskoningDHV and Witteveen+Bos. These two companies are experts in their own right and in a much wider field in providing design and consultancy services to enhance society. The establishment of TEC in 1988 brought together their combined specific knowledge, expertise and experience in soft ground tunnelling, guaranteeing continuity for the successful delivery of every tunnel project.
Although covering the design and engineering of all types of soft ground tunnelling, TEC is famous for their expertise in immersed tunnelling and world leading in this type of tunnelling. Since 1988, TEC has delivered design and construction solutions to the majority of the world’s most challenging and innovative tunnelling projects, such as the Øresund Link between Denmark and Sweden, the Busan Geoje Link in South Korea, the 32 km connection between Hong Kong, Zhuhai and Macao in China and the 20 km Fehmarnbelt Link between Denmark and Germany.
Providing expertise at all stages of (immersed) tunnelling projects – from conception and initiation, to design, delivery and operation, we use our integral, innovative and sustainable approach to deliver a multidisciplinary range of consultancy services. These include feasibility studies, design, tender documents and evaluation, design reviews, cost analysis, detailed design and construction supervision.
