A9 Badhoevedorp - Holendrecht, from planning procedures to contract preparations

The restructuring of the A9 arterial road at Amstelveen is part of the Schiphol-Amsterdam-Almere (SAA) programme. In brief, the A9 between Badhoevedorp and Holendrecht is to be widened to four lanes in each direction. A 1.3 kilometre section at Amstelveen is to be moved underground and covered over with two large surface structures.

Since 2014, Witteveen+Bos has been working closely alongside Rijkswaterstaat (the national department of transport and infrastructure) to produce the integrated design and the draft Routing Decision, which was approved by the Minister of Transport, Melanie Schultz van Haegen, in March 2017. Once the statutory consultation period has elapsed, attention will turn to the producing the contracting documents. The tendering procedure then follows, with work scheduled to commence in 2020. The A9 Badhoevedorp-Holendrecht project is the final component in the Schiphol-Amsterdam-Almere programme.

Further to the SO3 framework agreement with Rijkswaterstaat, Witteveen+Bos was recently retained to provide engineering consultancy services for various follow-up projects. We shall therefore be working closely with the department’s Technology Team throughout the period 2017-2025 and will be responsible for drafting DBFM contracts, overseeing the tendering process and subsequent negotiations, as well as all back office operations. We will also have overall responsibility for site management, project completion and sign-off. The contract was signed on 29 June 2017 by Hans Ruijter, SAA programme director for Rijkswaterstaat, and René de Boer, sector director at Witteveen+Bos.
