When a client asks you to renovate, adapt, or expand an existing building, the very first question isn't about finishes or floor plans. It's about structure. Can this building handle what the program demands?

Structural assessment is the process of evaluating an existing building's load-bearing systems, lateral-force resistance, material condition, and seismic vulnerability to determine whether renovation is feasible, what interventions are required, and whether demolition might be the more rational path. For the PA exam, you need to analyze assessment findings and make evaluative judgments about how structural conditions affect programming decisions.

The assessment process ranges from rapid screening methods (a trained professional spending 15 to 30 minutes per building, evaluating the lateral-load-resisting system from the sidewalk) through detailed engineering evaluations involving exploratory demolition, in situ testing, and load analysis. Each level of investigation produces different types of reports, and you need to understand what each report tells you and what it doesn't.

Structural findings don't exist in isolation. They intersect with MEP system conditions, hazardous materials, historic significance, and budget constraints. A building with a sound concrete shear wall system but deteriorated unreinforced masonry infill walls presents a very different programming scenario than one with corroded steel moment-frame connections. Your job during programming is to synthesize these structural findings with the rest of the project data and recommend a path forward.
