ABOUT
BIMv3 is a geospatial systems architecture and consulting practice founded by Nathanael David Sheean in 2025.
It extends more than twenty-five years of experience across construction, civil engineering, surveying, and information technology into a unified framework for intelligent infrastructure.
Our mission is to connect the physical and digital environments of modern cities through deliberate design, explainable intelligence, and durable data systems.
BIMv3 designs and implements the digital foundations of infrastructure—linking field survey, CAD digitization, GIS modernization, and AI-driven decision support into a single operational ecosystem.
Every engagement applies engineering discipline and data precision to deliver systems that are accurate, interoperable, and built to endure.
Less Fragmentation. More Integration.
