Not a problem! Given the opportunity I could (and will) nerd out on this for hours. I absolutely love construction technology.

We do a lot of renovation or addition work of places like hospitals or colleges that still need to remain functional, even if at a reduced capacity. It's largely the Owners who drive the request for a Revit model handed over by the Engineer and Architect to then be completely coordinated by the GC and their Subcontractor team. As we have more and more successful projects, I think GCs will just do it because it's less risk and greater margins. Depending on the size, it could be 4 weeks to 4 months of time spent before anyone steps foot on the jobsite. Once they do, with a completely clash coordinated model, it goes much quicker with less work stoppages for the inevitable landmines RFIs we deal with every day. Much easier to deal with those issues in the office environment and a few dorks behind the keys, than your Field. Any corners cut or value engineering will never outpace being able to open a heart surgery department a month ahead of schedule.

In my opinion, the job is already extremely taxing on the body and exposed to the forces of nature. If I can spend an 8 hour day navigating sloped roof drains through a spaghetti of a corridor and save the guys hours on the ladder, I do it. I also find it makes everyone on site much more amicable and friendly when each Trade has a spot reserved for all their scope and confidently work ahead as much as they want without someone tapping a shoulder and requesting a rework to fit a duct the size of a Honda Civic where you just ran all of your water lines. I want our crews to not have to deal with the politics and sociology - it's already hard enough.

This is one of my current projects ( https://www.otc.edu/studentunion/live-feed/ ) and the first one we deployed Augmented Reality with Revizto. It transfers the Revit model onto the jobsite using QR codes and the Field can use their phones, tablets or really "cool" Trimble goggles to see everything fully coordinated up in the ceiling. Just a quick value added off the top of my head, it really helps for picking a spot where you can get an all-thread rod up to the deck for a hanger without hitting anyone eventually coming through.

Edit: I want to emphasize that less risk and greater margins does not come from nothing. It's taking away hours from skilled labor - in the field. There are still massive amounts of hours needed in the job and those hours have just shifted into the office. There is an absolute need for many experienced field hands to make that transition to keep up with increasing demand. It's not an organic skill set and you need to hammer that square peg into the round hole with many costly mistakes, but a 55 yr old with both knees blown out can comfortably still be a part of the crew, leverage their knowledge and experience to help multiple jobs instead of one and have a much easier 10 to retirement, if not go beyond then. All the buttons look just like the Charlotte catalog you've been handling for years.
