Simple. Precise. Accurate.

Measure Twice . Manage Once

We Measure Stuff

PrismSquare cuts out guesswork. We turn reality into decision —because what isn’t measured will get mismanaged.

Built by construction pros, not theorists, we know the pressure of quality, schedule, and cost colliding. Through laser scanning, 4D planning & scheduling, and consulting, we surface issues early, eliminate uncertainty, and keep projects in control.

Services

Laser Scanning

If it can be seen, it can be scanned—and once scanned, it can be verified. We compare existing conditions to design intent to check quality and tolerances either before or after the fact, visualize the site for clearer communication, and convert data into other formats you need for seamless coordination. We’re here to make that process easy for you.

4D-Scheduling

Visualize time, sequence, and constructability—before it costs you and to help you win more bids. No Hollywood BIM—just practical 4D that adds real value by optimizing schedule and sequence.

Modeling

If it gets built, it needs to be right. We cut the BS and deliver construction-ready models backed by survey-grade detail.

Why Us?

Boots on Ground Experience

Built on real field experience, we know what construction crews need to succeed. With over a decade applying construction technology in the field, we deliver services that turn plans and models into reality—not just drawings.

Industry Standardization Engagement

Our team shapes the future of construction. Engaged in American Concrete Institute (ACI) committees, ASTM standards development, and advanced Laser Scanning research and testing, we bring recognized authority and proven expertise to every project.

Deliver in time and on time

On time. On schedule. With real value. We don’t cut corners or sell cheap services—we deliver solutions that prevent problems, optimize results, and support our clients every step of the way.
