In Rocourt, Liège, we have started construction of LS², a state-of-the-art maintenance complex for the vehicles and systems of the Belgian land forces. The project marks an important step in modernising Belgian Defence’s logistics infrastructure. The new site will help ensure vehicle availability, maintenance and technical support for decades to come.

The Belgian land forces are undergoing extensive modernisation and will operate an increasingly large and advanced fleet. While these vehicles offer new capabilities, they also require specialised support throughout their service life. LS², short for Logistics Support for Land Systems and pronounced ‘LS Square’, addresses this challenge.

From design to operation

As part of the T² consortium, Jan De Nul is working with Cegelec and VINCI to design, build, maintain and operate the new infrastructure. The LS² partnership brings together the expertise of Belgian Defence and the Belgian defence companies John Cockerill Defense, FN Herstal and Thales Belgium.

We are building the complex on a site covering approximately 30,000 m². It will include a 9,000 m² maintenance building, staff facilities, an inspection area for incoming and outgoing vehicles, processing and storage areas, washing facilities and an underground car park with 114 spaces.

The maintenance hall will feature 40 workstations, allowing several vehicles to be serviced at the same time. We will also equip the facility with specialised installations, including a blasting booth, spray booth, overhead cranes, brake test benches, a run-flat area and systems for recovering engine oil and coolant.

Energy-efficient and future-ready

Energy efficiency is a key consideration in the design. The building will feature approximately 2,000 m² of solar panels, low-temperature heating powered by air-to-water heat pumps, and heat recovery through dual ventilation systems.

Rainwater management has also been carefully considered. A 100 m³ reservoir will allow rainwater to be reused for sanitation and vehicle cleaning. In addition, a 1,250 m³ retention and infiltration basin will keep water on site for as long as possible before any excess is discharged.

Schedule: completion planned for mid-2028

Preparatory works began earlier in 2026 with the demolition of the existing infrastructure. Foundation works will run from October 2026 to March 2027, followed by structural works until October 2027. Finishing works and the installation of technical equipment are scheduled to continue until mid-2028.
