IN Brief:
- The design-and-build contract is valued at approximately €30m.
- Construction will run from August 2026 to November 2027.
- BIM will be used across the A++ energy-rated industrial development.
YIT has signed a design-and-build contract worth approximately €30m for a Leopard 2A8 tank production and maintenance facility within Lithuania’s Kaunas Free Economic Zone.
Placed by UAB Lithuania Defence Services, the agreement will be recorded in YIT’s third-quarter order book. Construction is scheduled to begin in August 2026 and finish in November 2027.
YIT Lietuva will carry responsibility for design and construction across a site of almost 10 hectares, where the development will comprise a principal production building and supporting auxiliary structures.
Lithuania’s A++ energy-efficiency classification will apply to the complex, while building information modelling will coordinate the industrial building, specialist services, equipment requirements, and construction sequence.
Kęstutis Vanagas, managing director of YIT Lietuva, said: “The Design-Build model is particularly important for projects of this kind, as it enables close coordination between design and construction processes and efficient decision-making throughout the entire project.”
The facility forms part of Lithuania’s expansion of defence manufacturing and maintenance capacity as European countries invest in domestic infrastructure supporting new equipment orders and long-term military readiness.
A tank production and maintenance plant places considerably different demands on a building than a conventional warehouse. Structural floors must carry heavy tracked vehicles, lifting equipment, machinery, concentrated loads, and repeated movement through service areas.
Door dimensions, turning circles, inspection pits, overhead cranes, ventilation, extraction, compressed air, power distribution, fire protection, secure storage, and maintenance access must all be developed around the industrial process.
Maintenance activity also requires separation between clean and contaminated operations. Oils, fuels, batteries, coatings, cleaning products, damaged components, and waste streams need suitable containment, drainage, ventilation, storage, and environmental controls.
The design-and-build model allows operational requirements to be incorporated directly into the construction information, reducing the number of contractual interfaces between designer and contractor. The client must still define equipment, loads, security requirements, process flows, and future expansion with sufficient precision.
BIM can support far more than visual coordination on a project of this type. A federated model can test vehicle clearances, lifting envelopes, machinery access, clashes between building services and production equipment, structural penetrations, and installation sequences.
Once the facility enters operation, the same information can support asset management, maintenance planning, and controlled records for building services and secure components, provided the final model is structured around operational needs rather than design deliverables alone.
The A++ target introduces another layer of technical coordination. Large industrial buildings carry substantial heating, ventilation, lighting, and process-power demands, while frequent opening of vehicle doors can increase heat loss and destabilise internal conditions.
Envelope performance, heat recovery, zoning, renewable generation, control systems, and process energy must therefore be designed together. An efficient building shell will produce limited gains where production systems and operating patterns remain outside the energy strategy.
Across Europe, defence programmes are increasing demand for secure manufacturing plants, maintenance depots, logistics buildings, ammunition infrastructure, training facilities, and upgraded military estates.
These projects combine conventional construction disciplines with stricter controls over access, information, resilience, and programme certainty. Personnel, digital platforms, data storage, and technical documentation may all be subject to additional restrictions.
Such controls can complicate the collaborative processes associated with BIM and integrated design. YIT will need to maintain enough information exchange for effective coordination while respecting limits imposed by the client and equipment programme.
Model-access controls, defined information classifications, secure file transfer, and clear responsibility for specialist data should consequently be established before detailed design accelerates.
The 15-month construction programme is concentrated for an industrial complex with this level of specialist equipment and servicing. Structural components, cranes, secure systems, building services, and production interfaces may all carry long procurement periods.
Early package release will need to be balanced against design certainty, particularly where changes to the production process could affect loading, clearance, or service requirements after orders have been placed.
The development adds another major industrial project to the Kaunas Free Economic Zone and strengthens the region’s place within Lithuania’s defence supply chain. Its long-term effectiveness will depend on whether the building can accommodate changes in production volume, vehicle configuration, and maintenance practice after operations begin.
