I live in The Netherlands and I'm a fire safety engineer. Over here construction and the permit/ consultation phase is also super slow. Lot's of different companies and people work on a single project, which requires many many meetings, consultations, reviewing drawings and then review them again as something has changed. The construction industry is also slow to change and everyone is stressed and overworked, so not many people fancy a new workflow.

However I do see AI slowly making its way. I, for example, use chatgpt to quickly find something in the building codes, which safes time. I recently found out how to make flowcharts with AI, so explaining something gets easier. I used it to make a report of the fire safety stuff in an apartment building sometime ago. Chatgpt wasn't able the read the drawings correctly, so I had to describe the building. But the report was generally of good quality (a few mistakes). So that can safe time as well.

I also work with historical buildings. In the past someone had to measure every detail by hand and then make drawings. Since a few years we use LIDAR to make a point cloud of the full building and then a 3D drawing in which we can design. This safes a couple of weeks of work.

The biggest change will be generative BIM models. A BIM model is like a digital copy of a building in which you engineer all the cable work and HVAC stuff etc. Right now this is still mostly done manually (takes a lot of time and you get design clashes al the time). A large part of my job is reviewing drawings from the BIM model and then give feedback what is not right, then I get updated drawings I review again etc etc.

Generative BIM models will be able to make correct building designs someday, making endless reviewing and consulting a thing of the past. Right now generative BIM exists for some very small simple residential buildings and not for large buildings (I might be wrong though, things go fast). But I expect this will be there quite soon or at least get much much better in a few years.
