Resilience and Risk Mapping. The standard moves heavily towards targeted risk assessment and modern environmental data.

This document is a for educational and quick-reference purposes only. It does not replace the full text of the ASCE 7-22 standard. All designs must be verified against the official American Society of Civil Engineers document and local building code adoptions (e.g., IBC 2024 references ASCE 7-22).

40ft x 12ft modular clinic (Risk Category IV). Location: Charleston, SC (Wind Speed: 170 mph ultimate, Exposure D near coast). Challenge: The unit must move to a new FQHC site every 6 months.

If your portable unit is going to a location with a wind speed of 140 mph or greater (e.g., Florida or Texas coastline), ASCE 7-22 requires protection against windborne debris.
