City of Amsterdam Project Zuidasdok

Fluor, together with Hochtief and Heijmans as partner in the joint venture ZuidPlus, was selected by the City of Amsterdam, ProRail and Rijkswaterstaat (Department of Waterways and Public Works) to deliver the Zuidasdok project.

​​The Zuidasdok project focuses on the widening and partial tunneling of the ring road A10 South and the redevelopment of the Amsterdam-Zuid Station and its surroundings.

Zuidasdok is located in Amsterdam's financial district, also known as the Zuidas.


Client's Challenge

​The Zuidasdok project includes the widening of approximately seven kilometers and a partial underground installation of the A10 South motorway. The ring road expansion will consist of 2x4 lanes for the main traffic ​​and 2x2 lanes for local destination traffic. The partial underground construction of the A10 at the Zuidas will provide Amsterdam-Zuid Station the possibility to grow into a high-quality public transportation hub.

Additionally, the previously separated sections of the Zuidas business district will be reconnected into one living, working and shopping area. With a contract value of € 990M (approx. $1.2B), Zuidasdok is currently one of the largest infrastructure projects in the Netherlands.​

Fluor's Solution

During the bid phase, Fluor provided the critical project experience (e.g. design-build and systems engineering) needed to win the project. The project was awarded using most economically advantageous tender (MEAT) criteria, in which the Client not only awards the project based on pricing, but also on the quality of the bid. The ZuidPlus solution was rated best on both price and MEAT criteria.

The vision for the project emphasizes accessibility, traffic flow and ease of use of the secondary road network and Amsterdam South Station during construction. Our goal is to minimize hindrances for road users, public transport users and the local residents. During construction, highway capacity will not be reduced by more than 10 percent.

The execution of Zuidasdok consists of two main phases - the re-baseline phase and the execution phase.

Re-baseline phase

A good and controlled design execution is the basis of a successful project. The Client has introduced a specific project phase focusing on integral preliminary design called the re-baseline phase.

During this phase, the Client and contractor work in the same office to achieve optimal coordination. A re-baseline report will be produced, in which an integral preliminary design is presented that meets the expectations of both the Client and the contractor and which controls the interfaces and risks adequately.

Execution phase

In 2019, the execution of the project will begin. Five main phasing steps will be applied: 

  • Detailed and execution design, preparatory actions – Beginning after the re-baseline phase, the focus of this step is on the detailed and execution design. In parallel, the project area will be prepared for construction and permit applications will be finalized. Logistical concepts and preparatory actions, such as felling of trees and detecting and rerouting of underground cables, will be completed.
  • Start execution - The Britten passage station will begin construction. Bypasses will be created to reroute the A10 highway and to provide more space to start building the tunnels, and the execution of Knooppunt Amstel en Knooppunt Nieuwe Meern will start.
  • Station passage ready - The Britten passage station will be completed. The existing main station passage will be taken out of service and will be widened after finalization of the first passage.
  • Completion of works - All tunnel works will be covered at this stage. All viaducts, bridges and the Minervapassage will be completed.
  • Public area completed - The old A10 will be demolished. The commercial spaces in the station will be finalized, including the public spaces in the center of the project.​


​As part of a joint venture, Fluor is constructing Zuidasdok, one of the largest infrastructure projects in the Netherlands.

Construction is expected to commence in 2019 and conclude in 2028. After completion of the project, the joint venture will execute a seven year maintenance contract for the tunnel.​​
