Rijkswaterstaat awards Heijmans contract to widen A50 Valburg - Grijsoord motorway (NL)

Heijmans Infrastructure has been selected by the Directorate-General for Public Works and Water Management to design and construct the widening of the A50 Valburg - Grijsoord motorway. The contract value amounts to approximately €50 million. The proposal submitted by Heijmans was evaluated on the basis of cost as well as quality. Heijmans received the top scores in terms of both cost and quality.

The contract involves the widening of the motorway in both directions for a distance of 14 kilometers between the Valburg (A15) and Grijsoord (A12) intersections. The motorway will be widened from 2x2 lanes to 2x3 lanes and the project will also involve the replacement of the entire road surface with double-layer highly porous asphalt.

A new ecoduct will be constructed between Renkum and Grijsoord, several existing civil works on the A50 between Valburg and Heteren will be replaced and the bridge across the Lower Rhine will be reinforced. The existing Dynamic Traffic Management System will be modernized and expanded.

The contract value and the qualitative portion were based on an integrated approach developed by Heijmans Infrastructure Integrated Projects (HIGP) with contributions from all disciplines within the Heijmans Infrastructure Sector. HIGP is responsible for the execution of the project, thus ensuring the use of an integrated approach.

Preliminary preparations will commence in the fall of 2009. The actual construction start date is the beginning of 2010. The work is subdivided into two segments.

The Valburg - Renkum road segment will be open to traffic at the end of 2010; the Renkum - Grijsoord segment in the first half of 2011.
