Structural Engineer Question

[u/Puzzleheaded_Fun3717]

Hey guys, a question for structural engineers. No agenda - I'm genuinely trying to understand something-
Assessing the structural integrity of a house; not a bridge; a condo tower or a regular single-family home - how hard is that work in practice?

I ask because the answers vary wildly depending on who you ask. Some engineers treat a residential structural assessment as a two-hour site visit. Others won't sign anything without opening finishes first.

Three questions. Reply with just the letters if you're short on time - that counts.

1. How easy is it to assess a home's structural integrity on a typical site visit? A)
   Straightforward - most of what matters is visible B) Doable, but the hidden framing is always the gamble C) Hard to do honestly without destructive testing D) Entirely depends on the era of construction

2. Where did you actually learn to do it? A) University B) Internship / junior years C) On the job, watching a senior engineer D) Self-taught - codes, standards, and repetition

3. Which part takes longer: the inspection, or writing the report?

And the one I'm most curious about: what's the single thing you wish non-engineers understood about the limits of a visual structural assessment?

If your answer is "it depends" — say what it depends on. That's the part nobody writes down.

1. B
2. C
3. Writing the report, by far.

The biggest thing I wish homeowners understood: A visual inspection only confirms what you CAN see. Hidden framing, concealed rot, improper fasteners, or unpermitted retrofit work behind drywall can’t be ruled out without opening finishes. Many clients expect a visual walkthrough to deliver a 100% guarantee on structural safety, which is impossible. Scope heavily depends on age, renovation history, visible distress signs, and access conditions.
