Client requirement
Decisions
Proposed concept
Places to sit and sleep, hygiene, organised storage, first-aid provision and essential controls are arranged around clear circulation.
Competent specialists derive air, power, water, wastewater and temperature-control requirements from the agreed occupancy, duration and scenarios.
Normal and emergency access are coordinated without creating a new fire, escape or accessibility risk.
Simple operating, communication and maintenance procedures are developed for realistic household use.
Deliverable
The mandate creates a decision-ready basis for specialist design and project delivery.
Initial Mandate / Feasibility Study
The final proposal reflects size, location, available information, specialist input, confidentiality requirements and required outputs.
| Integrated into a planned new residence | From CHF 15'000.- |
|---|---|
| Connected to an existing residence | From CHF 25'000.- |
| Standalone protected structure | From CHF 22'500.- |
Scope note:
The 72-hour figure is a protected-operation target, not a guarantee and not necessarily a period sealed from outside air. Final capability depends on verified occupancy, air, power, water, wastewater, temperature, supplies, maintenance and system performance.
