The project involves the construction of a new underground civil defense structure (radiation shelter) on the territory of the “Olenka” preschool educational institution of the Mayakivska village council, which will allow solving the critical problem of the safety of children and staff in conditions of martial law and possible radiation threats. The implementation of this construction project will ensure the creation of a reliable monolithic reinforced concrete shelter of group P6 with a protection factor of 100, which is designed for the simultaneous stay of 330 people and is able to function autonomously thanks to its own life support systems. The planning solutions provide for the creation of comfortable conditions for a long stay, including a shelter hall with places to sit and lie down, a medical room, a room for storing food, bathrooms and technical rooms, while the reliability of operation is ensured by a mechanical ventilation system, tanks with a supply of drinking water for two days and a diesel power plant for emergency power supply. The project pays special attention to accessibility and inclusiveness, as a vertical lift, specialized bathrooms, wide doorways, and tactile navigation elements have been designed for access by people with reduced mobility, ensuring equal access to safety for all categories of citizens. The expected result of the project, which has an estimated operating life of 100 years, will be the commissioning of a modern protective structure of the CC2 impact class, which will allow for the restoration of a full-fledged educational process in the institution and ensure reliable protection of the community population.
