Prestressed and post-tensioned concrete. Flag this hard: PT is the most dangerous thing in a demolition. Stored energy, no visible warning.
PT is a hold. Storey tendons. A licensed engineer. We do not cut a tendon from a note on this site.
A university, a code, or a named issuer owns the long course. What we host is how this shows up on a demolition job — not a degree, not a licence.
On a plot: if you cannot say what is known vs assumed, do not send a number or a method. Read the building. A collapse study we run is DemSim — we never design the cut.
Site hours with someone who already has judgement have no video substitute. Tick only when you have an artefact.
Before you tick
- I can name what is known vs assumed.
- I have an artefact, not only watch-time.
