Construction of €492M Rijnland Route in Netherlands to stimulate economic growth

  • A JV with cutting edge expertise in tunneling, consisting of TBI companies Mobilis and Croonwolter&dros, DIMCO (DEME Infra Marine Contractors) and VINCI Construction Grands Projets
  • A new road to connect Katwijk and Leiden in South Holland, Netherlands
  • A €492 million contract

Rueil-Malmaison, France, 07-Feb-2017 — /EuropaWire/ — The Province of South Holland has awarded the contract for building the Rijnland Route to Comol5. This international joint venture consists of TBI companies Mobilis and Croonwolter&dros (25% each), DIMCO (DEME Infra Marine Contractors) (25%) and VINCI Construction Grands Projets (25%). The value of the contract is 492 million euros.

The Rijnland Route is the new road connection from Katwijk, via the A44, to the A4 at Leiden. The Rijnland Route is being constructed to improve the accessibility and traffic flow in the region, and stimulate economic growth.

Comol5 will be responsible for the reconstruction of the Leiden West motorway junction and the construction of the 4 km new road N434, including a 2.2 kilometre-length bored tunnel. Comol5 will also implement 12 km of motorway widening and adaptations to the A4 and A44 required for construction of the Rijnland Route. These will be made under traffic with pertaining interchanges. In addition to construction, which will be completed in about 6 years, the contract comprises maintenance for 15 years.

The project partners of Comol5 have ample experience with designing and developing large infrastructural projects such as bridges and tunnels, particularly bored tunnels. Projects they were involved in included a.o. construction of the Coentunnel and the Delft railway tunnel in the Netherlands by TBI and DIMCO, as well as the duplex tunnel (bored double-deck tunnel) in the A86 near Paris by VINCI.

Comol5’s tender turned out to be the most economically advantageous tender (MEAT). This means that not only price but also added value was considered. Criteria that play a role include limiting environmental nuisance, traffic nuisance and risks.
