Building Design Methodology: Using Lidar Imagery and GIS?

[MekkA 0]

I am completely newb to 3D software and asset creation but am starting to fall into the deep rabbit hole of learning. Given the accuracy I'm sure most creators adhere to for matching their assets to the real structure, I was wondering if anyone here has utilized this path to extracting building data?

As I work for a major municipality using GIS daily, we recently released a major set of satellite imagery and some googling showed me that extracting accurate building footprints and 3D dimensions is a huge benefit of LIDAR. 

If someone has gone this route for their building designs, what methodology could be used to then migrate that data into a usable base for 3D modeling software?

Thinking about this also makes me generally wonder: If this is not a common method in getting accurate data for a future building asset, what are some of the more common ways in which creators ensure their designs are in fact "accurate?"

Thanks everyone!
