Shelter construction

Purpose-designed shelters and protected rooms

A shelter is an engineered structure, not simply a reinforced basement. Its design depends on the intended threats, occupancy, duration of use, soil and groundwater, structural loads, available exits and the level of autonomous operation required.

PNV Construction Group can coordinate the architectural, structural and engineering parts of private shelters and protected rooms. Final solutions must be based on project documentation and the actual site, rather than on a standard wall thickness or a copied plan.

Questions addressed during design

location, access, concealment where appropriate and separation from hazardous building systems;
soil conditions, groundwater, flotation, drainage and external waterproofing;
structural resistance, penetrations, protective doors and emergency exit arrangements;
ventilation, filtration, overpressure strategy and safe service penetrations;
water, sanitation, power, communications and backup systems;
fire safety, moisture control, maintenance access and periodic testing;
occupancy, storage, sleeping arrangements and realistic endurance requirements.

The project may range from a protected room integrated into a house to a separate underground structure. Equipment and protective features are selected according to the design basis; broad claims of protection should not replace calculation, testing and documented installation.

Safe-room references

Safe rooms and storm shelters used in other countries demonstrate different approaches to short-term protection. A solution for a specific property must be adapted to local threats, structural conditions, ventilation and escape requirements.
