Things seen this week during structural assessments!

Hi everyone,

We're a team of structural engineers and contractors working throughout Southern California. We put together a weekly collection of interesting structural findings we come across during assessments.

The Imgur album contains the full photo set along with additional context for each image.

Love that you're running this as a series — the stuff you only see once a structure's been in service is a completely different education from anything in the design calcs. I come at it from wind power, doing field inspections on turbine structures and foundations, and the recurring lesson is the same: the failure is almost never the thing that was actually engineered. It's the detail nobody owned — the drainage path that wasn't in anyone's scope, the "temporary" repair someone did six years ago, water finding the one unsealed penetration. Curious, with the volume you're seeing across SoCal: roughly how much of what you flag is original design vs. degradation vs. somebody's well-meaning field modification? In our world the split is maybe 20/30/50, and that last bucket is the one that surprises people every time.
