Contract Description
Rijkswaterstaat has awarded a supplementary contract with a value of EUR 3.46 million to The Coentunnel Company (CCY), a consortium consisting of Mobilis, Dura Vermeer, and Besix.
The award relates to the existing contract signed in 2008 for the design, construction, financing, and maintenance of the first and second Coentunnels, which remains in force until 21 December 2037.
Scope of Works
The supplementary works form part of CCY’s ongoing availability and maintenance obligations and include additional activities associated with:
• Design and engineering interfaces
• Tunnel software and control systems
• Technical installations
• Safety systems and structures
• Integration with existing tunnel infrastructure
The contracting authority determined that only CCY possesses the required technical expertise and system knowledge to carry out these works safely and efficiently. Transferring the scope to a third party would have resulted in disproportionate time and cost implications, increased safety risks, and potential disruption to tunnel operations.
Contract Value
• Supplementary contract value: EUR 3.46 million
• VAT: Excluded
Contract Duration
• Contract validity aligned with the original concession
• End date: 21 December 2037
Procurement Information
The contract was awarded directly without prior publication due to technical exclusivity, safety considerations, and continuity requirements under the existing long-term contract.
