The A9 Gaasperdammerweg public-private partnership (PPP) project in Amsterdam, the Netherlands has reached financial close. Mott MacDonald is lenders’ technical advisor to the IXAS Zuid-Oost B.V. consortium for the project.
Worth approximately €700 million, the scheme will see the reconstruction and expansion of the A9 motorway between the junctions of Holendrecht and Diemen, including a 20 year management and maintenance period after the new infrastructure becomes available. Works include replacing the bridge over the River Gaasp, relaying the surface of the motorway and constructing a new 3km overground tunnel. The new tunnel will increase the quality of life in the area by improving air quality and minimising noise pollution. Additional lanes will be provided to improve traffic flow and accessibility of the Northern Randstad area.
Mott MacDonald provided due diligence and technical reports to support financial close and is now monitoring construction to help the project stay on programme and budget.
Joost van Loon, Mott MacDonald’s project director, said: “This project builds on Mott MacDonald’s previous infrastructure experience in the Netherlands and Belgium, where we are one of the leading providers of technical advice having worked on over 20 PPP schemes.”
Construction work is due to begin in the summer of 2015, with the tunnel expected to be available for traffic in 2020.
