Start with people, use and operating conditions
Record who the infrastructure is for, how many people will use it, whether the need is temporary, transitional or permanent, and what services must remain operational after handover.
Avoid starting with a supplier catalogue. Housing, clinics, classrooms and sanitation blocks can use similar structural systems while requiring very different privacy, hygiene, accessibility, fire, utility and maintenance outcomes.
- Population and user groups
- Expected service life
- Daily and peak occupancy
- Climate and hazards
- Accessibility and safeguarding needs
- Local operating and maintenance capability
