Welcome

The challenge for every organization is to successfully deliver infrastructure projects in terms of money, time, and quality.

In recent years, the civil engineering market has changed significantly due to the increase in innovative contracts (D&C, DBFM, FIDIC). This requires specialized knowledge of the various aspects of these contracts.

It also requires a different approach to setting up the project organization. Increasingly, the IPM model is being used for this purpose.

For decades, the A2 motorway divided the city of Maastricht in two, running straight through it at ground level. This situation was far from ideal for traffic flow and for the quality of life in the city.</p><p>The solution came with the construction of a unique double-layer tunnel, the first of its kind in the Netherlands. The innovative design not only improved traffic safety and reduced congestion, but also gave the city back its unity.

Double-layer Tunnel Maastricht

The Hanzelijn is a 50 km new railway line connecting Lelystad and Zwolle, featuring crossings with existing infrastructure, a rail tunnel under Lake Drontermeer, adjustments to major highways (A6, N50/A50), and a new railway bridge over the IJssel in Zwolle. As one of the first major D&C contracts in the Netherlands, this project set a benchmark for large-scale infrastructure tendering.

The A4 project involved the widening of the motorway between Burgerveen Junction and Leiden, one of the busiest traffic corridors in the Randstad region. Key works included the construction of a second aqueduct under the Haarlemmermeer ring canal and a sunken section near Leiden to improve traffic flow and reduce environmental impact.</p><p>Hans Grabandt played a crucial role as Technical Manager during the execution phase, ensuring seamless integration of engineering disciplines, contract requirements, and on-site delivery. His contribution was essential in completing this high-profile infrastructure upgrade successfully.

To improve traffic flow around the southwest of Leeuwarden, the old route via secondary roads was replaced with a new 2x2 motorway connection. This major upgrade reduced congestion, improved regional accessibility, and enhanced road safety. Hans Grabandt contributed during the contract preparation phase, providing technical management that ensured the project’s requirements were clearly defined and effectively integrated into the tender process. His role was key in laying the groundwork for a smooth execution of this vital infrastructure project.

As part of the expansion and renovation of the Schiphol – Amsterdam – Almere corridor, the A9 Gaasperdammerweg was widened to 11 lanes. A highlight of the project is a 3 km land tunnel, designed to reduce noise, improve air quality, and reconnect neighborhoods previously divided by the motorway.</p><p>Hans Grabandt was responsible for the contract preparation phase, including Systems Engineering, drafting of requirements specifications, and coordination of civil engineering disciplines. His expertise ensured a clear technical framework and smooth execution for this complex infrastructure upgrade.

The Rijnland Route is a new east–west road link between Katwijk, the A44, and the A4 south of Leiden. A centerpiece of the project is a bored tunnel connecting the A4 and A44, designed to improve regional accessibility and reduce traffic congestion.</p><p>Hans Grabandt provided design optimization, merging fragmented sketches into a coherent and practical plan. His work not only improved the overall design but also delivered savings of more than €15 million, proving the added value of strong technical and contract management in complex infrastructure projects.

Weirs and locks are essential water management structures in the Netherlands, used for centuries to regulate water levels. A new approach was introduced by tendering the replacement of multiple weirs and renovation of locks under innovative E&C and D&C contracts.</p><p>Hans Grabandt played a pioneering role in introducing these contract forms at Waterschap Hollandse Delta for this type of project. With his expertise in contract and technical management, he helped shape a more efficient and scalable method for maintaining critical water infrastructure.

The Werpsterhoek junction, located near Leeuwarden, is a key connection point for traffic coming from the Harlingen direction. As part of the N31 Leeuwarden bypass project, the junction was redesigned to improve traffic flow, safety, and regional accessibility.</p><p>Hans Grabandt contributed during the contract preparation and technical management phase, ensuring that the design and requirements were clearly defined and integrated into the tender. His role helped create a solid foundation for the smooth delivery of this critical infrastructure link.

The Rio Doce Railway project in Aimorés, Minas Gerais, involved improving and modernizing rail infrastructure in a region known for its complex geotechnical and hydrological challenges. The works were essential to enhance safety, reliability, and connectivity for both freight and passenger transport.</p><p>Hans Grabandt contributed as a geotechnical and technical management expert, applying advanced engineering methods and knowledge transfer to ensure the project’s successful design and execution. His role helped bridge Dutch expertise with Brazilian railway development needs.

The A2 motorway is one of the Netherlands’ most important traffic corridors, connecting major cities from Amsterdam to Maastricht. Over the years, several large-scale projects have been carried out to widen, redesign, and upgrade sections of the A2 to improve capacity, safety, and regional accessibility.</p><p>Hans Grabandt contributed to the Maastricht section, where the A2 previously split the city in two. His role in the tender and technical management phase helped deliver the innovative solution of a double-layer tunnel combined with a green park on top, reconnecting neighborhoods and improving the city’s quality of life.
