My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
Could also be finished glue laminated ... looks like 2 or 3 inches thick, but you can request whatever thickness you want. Suggest partial wrap with accent color rug to protect against someone slipping?
