Over the next years, Rijkswaterstaat and TEC will work together to complete the plan study, prepare the contract, and supervise the implementation of the renovations.
Most tunnels in South Holland were built in the second half of the last century or at the beginning of this century. To keep them safe and accessible in the future, Rijkswaterstaat will renovate the tunnels.
Largest engineering services contract ever awarded by Rijkswaterstaat
Never before has such a large engineering services contract been tendered by Rijkswaterstaat. Starting early next year, TEC will map out exactly what work is required per tunnel, starting with the Noordtunnel. This is followed by the Drecht tunnel, Benelux tunnel, Sijtwende tunnel, Tweede Heinenoord tunnel, Thomassen tunnel and Botlek tunnel. Rijkswaterstaat and TEC jointly supervise the tenders for the contractors who will carry out the work.
