Apply ACI 362.1R guidance when scoping the design/durability review portion of a parking structure condition assessment

Steps

1. Confirm which structural system is present — cast-in-place nonprestressed concrete, cast-in-place post-tensioned concrete, or precast/prestressed concrete — since ACI 362.1R's durability guidance differs by system.
2. Document the structure's environmental exposure category (proximity to seawater, deicing-salt exposure frequency, freeze-thaw cycling) as ACI 362.1R uses these to set governing durability criteria.
3. Cross-reference the guide's recommendations against the structure's original design documents (if available) to identify any gaps versus current durability practice (e.g., concrete cover, air entrainment, corrosion protection systems).
4. Use the guide alongside ACI 318 and applicable ACI specifications/standards, since 362.1R is explicitly meant to supplement rather than replace the general concrete design code.
5. Flag any design-era deficiencies identified (e.g., inadequate drainage slope, insufficient cover) as inputs to the repair-design phase governed separately by ACI 562.
