SketchUp for Infrastructure / Civil Engineering Construction

I’m an estimator in the Infrastructure / Civil Construction space.
Seems we’re a bit like 2nd cousins to building / architecture / landscaping …
Guess maybe partly down to we haven’t been as good at Extension development as the rest?
One issue I’ve grappled with is cut/fill earthworks qty’s. there seems to be a tipping point that once you go beyond a certain size it just seems impossible to achieve.
Then stuff like creating bridges. There’s potential for and Extension or 2
Stormwater etc, etc
Is there already a community of us I haven’t found yet?
Or do we need to create one?
Look forward to connecting and developing further
