Bunker types compared
bunker24.lt offers four types of protective structures – block, underground, metal and Extra bunkers. Each has its own strengths: we have compared their construction, capacity, lead times and what each type is best suited to.
How institutions can acquire a shelter: procurement and funding
Buying a shelter in the public sector: from CPO LT to funding
State and municipal institutions acquire shelters in line with public procurement rules. It is therefore worth knowing in advance which route the purchase can take and what funding can be expected.
Procurement routes
Centralised purchasing through CPO LT
The CPO LT e-catalogue is an information system in which contracting authorities can purchase goods, services or works, and businesses can offer them. The Law on Public Procurement (Viešųjų pirkimų įstatymas) determines when a contracting authority must purchase from or through a central purchasing body.
Municipal centralisation
In each municipality, purchases by the contracting authorities it controls whose value exceeds EUR 15,000 excluding VAT must be centralised through the municipality's own or another central purchasing body.
Independent procurement
Where centralised purchasing does not apply, the institution buys on its own under its procurement rules.
bunker24.lt takes part in public procurement, provides quotes for market consultations and budget planning, and helps prepare technical specifications.
What to prepare before announcing a tender
- Calculate how many people the shelter must accommodate (the 60% rule for new buildings, 1.5 m² per person).
- Decide what protection level of shelter is needed (up to 5, 24 or 72 hours).
- Assess the site: land ownership, utilities, access, and whether a building permit document is required.
- State in the technical specification the requirement to comply with STR 2.07.02:2024 (Lithuanian construction technical regulation on the design and installation of shelters) and the documents required.
You can bring in our engineers for this preparatory work: we will prepare technical solutions and a preliminary budget.
State funding for shelters
The Ministry of the Interior funds municipal shelter modernisation projects from the State Defence Fund. Under the funding conditions, shelters are divided into three levels:
- Level 1 up to 72 hours Intended for use for up to 72 hours and must fully comply with STR 2.07.02:2024
- Level 2 up to 24 hours Intended for use for up to 24 hours
- Level 3 up to 5 hours Intended for use for up to 5 hours
In September 2026, the Ministry of the Interior (VRM) published draft conditions for the third call. They provide for:
EUR 16 millionallocated in the third call
EUR 55,000on average per shelter
EUR 155,000maximum per shelter
Other shelter managers could also take part as partners. Works started from 1 June 2026 could also be funded.
This is still a draft: the final conditions will be published by the Ministry.
Whether a specific project and solution meets the funding conditions is determined by the final call conditions and the assessment of the institution administering the funding. This is worth checking while the project is still being planned.
