About BIMstream
BIMstream is an infrastructure company for the built environment.
We capture buildings with measurable precision, transform that data into governed digital twins, and maintain those assets as long-term operational infrastructure. CERQA sits on this foundation - enabling system integration, portfolio oversight, and data-driven decision making at scale.
Our work is executed entirely by full-time BIMstream architects and engineers. Production, quality control, and long-term stewardship remain under our direct responsibility. The integrity of the platform depends on the integrity of the data beneath it.
We build that foundation.
Our Team
BIMstream is built entirely around architects, engineers, and technical specialists - the people who understand buildings from the inside out.
Our field teams bring professional-grade LiDAR discipline to every site. Our Studio transforms that data into structured digital twins, built to defined EMD standards and reviewed internally before anything reaches a client.
We work across offices and time zones, but the standard never changes. CERQA runs on data we stand behind - not assumptions.
That accountability is built into how we operate, at every level.
