Heijmans to build Army Technology Centre for Ministry of Defence

The Dutch Central Government Real Estate Agency (Rijksvastgoedbedrijf) has awarded construction company Heijmans the contract to build a new Army Technology Centre (Technologie Centrum Land or TCL) in Leusden, a location for various operations related to the Ministry of Defence's ground-based materiel. Heijmans will start preparations for construction this year, with construction itself set to continue through to the end of 2027. The contract represents a revenue value of approximately € 177 million.

In 2028, the new Army Technology Centre (TCL) will replace the current accommodation of the Technical Department of the Dutch army's Materiel Logistics Command in Leusden, which is outdated and no longer fit for purpose. The TCL will provide multifunctional facilities and has been designed with a focus on safety and health, as well as sustainability, future-proofing and functionality.

Former barracks

The new facility will be located on the adjacent site of the former Tank Workshop in Leusden. The Technology Centre Land (TCL) will feature state-of-the-art workshops, testing facilities, and office infrastructure. Special attention is being paid to the surrounding environment and landscape integration.

The Technology Centre Land represents a significant step in the modernisation of the Dutch armed forces. With this initiative, Heijmans contributes to the renewed defence mission of the Netherlands.

Expertise

Winning this contract underlines Heijmans' position as a reliable partner to the national government in the realisation of complex and socially relevant construction projects. "We are proud that we can use our expertise to help to strengthen the technological capabilities of the Ministry of Defence," says Heijmans CEO Ton Hillen.

Heijmans' approach in the tender process was clearly aligned with the client's vision, with two aspects standing out in particular. The first was the construction site organisation and the construction methodology to be used. On this front, Heijmans can draw on its extensive experience in completing complex projects at existing locations both efficiently and effectively. On top of this, the government greatly appreciated the deployment of specialised teams.

Heijmans' strategic pillar of Sustainability is reflected in this project through the use of recycled steel and so-called 'reinforced soil'. This latter approach is a technique used in infrastructure works, and will reduce the amount of concrete foundations needed in Leusden. Less concrete used means lower CO2 emissions.
