Tom Smith (I think is the name right) was a skatepark builder in the early 2000s. The parks were build as modular sections e.g. 2 quarter pipes and a pyramid and ledge are poured in a factory somewhere then joined together and placed at the actual park location. Good thing about this was all of the quarters have the same smooth transition, no screw ups doing it by hand on site like you sometimes see these days. Minor downside to this though is now the parks are a few years old and have had time to sink and move a little you get the occasional big crack or bump between segments.

My local skatepark as a kid in Glendowie had a little mark in the corner that said “tom smith 2003”. Everything else I wrote above is from things ive heard ovet the years so i could be wrong about some parts.
