The A9 Badhoevedorp and Holendrecht project can rightly be referred to as a megaproject. This route is one of the busiest connections in the Netherlands. To improve the accessibility of the northern Randstad and simultaneously the quality of life in the area, the A9 will be expanded from two three-lane roads to two four-lane roads. A project with many technical and organisational challenges. Commissioned by FCC Construcción, Iv-Infra is making the preliminary design and final design for the widening of the Schiphol Bridge (movable bridge), three fixed bridges, five viaducts and a new recessed position. As an intern, you will support all project and design management matters, such as system engineering, interface control and planning. Together with your colleagues, you will be the sparring partner for this project. This challenge will give you a good impression of working in a project environment with multiple parties.
