The answer to that question is complex, and involves both legal and technical perspectives. But it all starts with the original conditions of the basement.

GER³ has visited many schools across Ukraine, assessing facilities to understand if they can be re-opened. There are some common issues we see in many school basements which prevent them from being safe spaces for children.

Moisture: Many basements lack proper insulation, causing them to flood during periods of rain or snow melting. Moisture can also build in the walls and air, causing mold and stuffiness. These conditions can trigger allergies, asthma, respiratory infections or other health problems.
Lack of proper ventilation: Without ventilation systems, when children are in the basement for a long period of time, available oxygen is depleted and it can become hard to breathe.
Dirt floors: When floors are unfinished, dust is continuously kicked up into the air, especially when there are many people using the space. This can create similar respiration and health challenges as moisture.
Unfinished systems: Lack of electricity, heat running water, etc. are problems in and of themselves, but unfinished systems can also create safety hazards. We commonly see exposed wires, gas and water pipes, creating dangerous conditions for students if they were to use the space as a shelter.

In addition to these dangerous health and safety conditions, most basements also do not include features essential for the shelter in case of emergency: airtight doors, strong ceilings and walls, and two separate evacuation routes.

Depending on the initial technical conditions, legal status of the basement (some have legacy status as a ‘simple’ bomb shelter, although they do not meet current safety standards) and governing regulations, the level of intervention required can differ.

Anti-radiation shelters

In some regions, like those closer to the frontline, requirements for school shelters are stricter, mandating “anti-radiation” spaces designed to block and absorb radiation. This requires very specific features, and a thoughtful engineering approach.

Anti-radiation doors: These doors are lined with materials which can block harmful radiation. Additionally, they protect the space from any shrapnel or debris which may result from an attack.
Ventilation system: Specialized ventilation system designed to supply safe, breathable air, absorbing any harmful chemicals. Systems are designed to function through power failures, which are regular in Ukraine, as a result of the war. Ventilation systems are stored in a separate room to create a safe environment for people using the space.
Reinforced walls: Dense, heavy walls are reinforced to absorb radiation and withstand the impact of munitions.
The ventilation room houses all the centralized ventilation equipment and draws in fresh outdoor air. Creating a safe filtration system typically requires exterior works to run pipes up to the ground level and safely position air intake vents. The separate ventilation room contains any noise or vibration and isolates the equipment from learning spaces.

Level of construction

Based on the works required, the project may require general repairs, capital (structural) repairs, or reconstruction. These are all different construction classes in Ukraine, with increasing complexity and oversight requirements. Reconstruction requires formal construction permits from the State Inspectorate of Architecture and Urban Planning and a mandatory comprehensive expert review of the engineering design documentation. GER³ manages each step of the approval and construction process, facilitating the project from initial assessment to final re-opening.

Innovative design

There is legislation that governs the minimum standards for all new shelters. In general, these standards were designed for new construction (building a shelter from scratch), so it requires ingenuity to design a project that meets all requirements within an existing basement. Alongside meeting bomb shelter requirements, we also design spaces that are dual-use, able to serve as functional classrooms for students to continue learning during air alerts. GER3 engineers work alongside project designers and contractors to craft solutions, carefully arranging all necessary components, while ensuring the space will be functional for education purposes.

Accessibility

Incorporating accessibility is a key element of the construction design. We want all children to feel safe and empowered in the space.

Inclusive bathrooms: Bathrooms with wide entrances and handrails allow children with disabilities to navigate the space independently.
Accessible emergency entrances and exits: Disability-inclusive access, such as ramps, lifts or stair lifts, is designed to suit each shelter and help children with disabilities enter and exit safely and independently where possible.
Level floors: One thing that can be extremely problematic for children with mobility or visual challenges is when floors are not level. Uneven floors can disrupt balance, sensory feedback and mobility devices. When installing new flooring, we take the time and effort to ensure that they are level, creating a space all children can feel confident using.

Transforming a space from basement into a bomb shelter is rigorous challenge, requiring the technical expertise and depth of experience our engineers bring to the job. From initial assessments and testing, to the project design development and approval, and throughout the entire construction process, they are there every step of the way, ensuring a high-quality end result, where students can safely learn.

Your support can help GER³ rehabilitate safe, accessible school shelters so children can continue learning during air alerts.
