Stage 1: conditions and requirements
Record dimensions, photographs, services, moisture traces, access and known defects. Add purpose, occupancy and duration. Only after this baseline is credible should design options be drawn and assessed.

Plan a shelter in reliable stages
Assess, design, approve, build, commission and test are separate stages.
Many poor decisions occur when equipment is purchased before the space, moisture, exits and air have been resolved. A staged process protects both budget and safety because every phase has a clear result and a stop point.

Decision compass
Decide safely
Four questions lead from observation to a clear, safer action.
What needs to be clarified now?
What must I notice first?
- Record household needs, dependencies, current official information and available safe locations.
- Agree responsibilities, communication rules and a fallback before time pressure develops.
Remember: Observe → assess → choose a safer option → act.
Each stage ends with documented assumptions, approvals and open issues.
Learning goals
- Separate project stages
- Place specialist reviews at the right time
- Document changes traceably
Stage 2: specialist design and approval
Structure, ground, fire safety, ventilation, electrical work and drainage involve different disciplines. Responsibilities and interfaces must be settled before construction. Product data does not replace site-specific design.
Stage 3: build, commission and operate
Concealed layers are photographed and checked before closure. Functional tests, readings, defect lists and training follow. Only an occupancy drill shows whether routes, air, light, sanitation and procedures work together.
Practical check
- Create a condition record
- Define decision gates
- Name disciplines and interfaces
- Document concealed work
- Schedule commissioning and occupancy drill
Important
- Do not buy equipment before feasibility is checked
- Do not leave changes undocumented
- Do not confuse self-checking with independent commissioning
Decision training
When should expensive ventilation equipment be selected?
- ABefore assessing the room
- BAfter the airflow concept and specialist design are resolved
- COnly during the occupancy drill
Show answer
Correct: B. Equipment must match the room, airflow path, operation and maintenance concept.
