It cites the high‑profile failures of Katerra and Veev as cautionary tales of over‑integrated, Silicon‑Valley‑style disruption. Ultimately, the author contends that the industry’s fragmentation is a liability‑buffer, not a bug to be fixed.

From Static Data to Spatial Teammates: How SIMA 2 Breathes Life Into BIM
Google DeepMind’s SIMA 2 introduces a general‑purpose AI agent that can reason, act, and learn inside 3D virtual worlds, turning static Building Information Models into interactive environments. By embedding the agent in BIM and GIS models, users can issue natural‑language...

The Compliance Paradox: When Bad BIM Data Bypasses the Rules
Automated building permit checks increasingly depend on BIM data labels rather than physical geometry, creating a loophole where mis‑classified elements pass compliance tests. The article illustrates how this “false positive” trap lets developers bypass safety rules, shifting risk to municipalities...
