Dutch A4 road contract

By Sandy Guthrie03 October 2011

Dutch group Heijmans has said that the Directorate-General for Public Works & Water Management (Rijkswaterstaat) is planning to award the contract for the A4 road from Delft to Schiedam to the A4ALL joint venture comprising Boskalis, Heijmans and VolkerWessels.

The Heijmans part of the contract is said to be valued at more than €125 million.

The contract is for the construction of 7km of the A4 between Delft and Schiedam in the western part of the Netherlands.

It will feature a 2km land tunnel, an aqueduct and ecoduct (for wildlife), a number of civil works crossings, and 12km of sound barriers. The contract includes maintenance for at least eight years, plus the demolition of the Kethelplein intersection and the installation of new covering layers on the existing A4 north, the A20 and the A4 south.

Work will begin in 2012 after final contract award, and it is expected to be completed in 2015.

Heijmans operates in the Netherlands, Belgium and Germany.
