Contract

The work will be carried out based on a DBFM (Design, Build, Finance and Maintain) contract. This means that the construction consortium will be responsible for the design, building, financing and maintenance process. The contract term is 30 years. The A1/A6 will be expanded over a distance of 20 kilometres. This includes two reversible direction lanes across the entire expanded section.

Road expansion

Construction consortium SAAone was selected based on the Most Economically Advantageous Offer (MEAO) method, which looks both at price as well as quality. The parties involved all have a lot of experience with comprehensive construction projects including maintenance. Thanks to the construction consortium's mutual expertise, it is the ideal candidate for the job.

Planning

Preparatory work is planned for 2013, with the actual construction work commencing in 2014 and scheduled to last until 2020.

The expansion of the road system between Schiphol Airport, Amsterdam and Almere aims to achieve:

  • Improved accessibility of this economically important region
  • Smoother flow of traffic
  • Shorter and more reliable travel times
