Using CAD for Building & MEP Cost Planning

I enjoy how Onshape helps engineers and designers build 3D models, mechanical parts, and complex assemblies. I wonder if we can use CAD model especially for building design to help estimate real-world building costs easier. For example, after designing basic structure, one could use outputs to perform mep estimation services to get cost for plumbing, HVAC, electrical conduits etc before actual construction.I think combining CAD design and accurate cost estimation may help avoid surprises and save time. Has anyone tried something similar using CAD export or building plan to get building cost estimate or MEP planning report? I’m curious if this community sees value in bridging CAD design and real-world building estimation.

I don't know all the tools that they've built internally, but Reframe Systems is using Onshape extensively to model and manufacture semi-custom prefab homes.

I have used Onshape for af few trade show stand building projects in the past. You know: Steel frames, wall modules, floor tiles, custom parts, electrical, a bit of plumbing, media all mixed together. After all, it is not more real world than other design jobs only because it is bigger. My client loved the way they could always see the current state or even watch me making changes while in an online meeting. The carpenter loved the BOM always being up to date and being able to view "how it is meant" in his web browser. External suppliers were not so happy with me sending them an Onshape link when requesting a quotation, though. It just wasn't autoCAD. There would have been some onboarding due first. I need to revert to PDF drawings for some.
I think it depends heavyly on what automation tools would be available in a adequate architectural CAD system. Also, it would be important within what type of ecosystem you'd work. If it was largely CNC-driven and had many remote contributors, Onshape might have a point. I'd plan my house with it, but then, my house would be highly modular and not require a single mason on the site. ;0)
