I help clients **capture the physical world, convert it into accurate 3D data, and turn that data into usable BIM/CAD models**. I also help companies and product teams develop, integrate, calibrate, and test their own **LiDAR, depth-camera, computer-vision, and SLAM mapping systems**. I bring **15+ years of BIM/VDC experience and 8+ years of reality-capture experience** across LiDAR, Matterport, photogrammetry, drones, point clouds, mobile mapping, and Scan-to-BIM. ## REALITY CAPTURE & 3D SCANNING I can help determine the right equipment and workflow based on **interior vs. exterior conditions, project size, accuracy requirements, site access, schedule, budget, and final deliverables.** **Small Interiors — Homes, apartments, retail, offices, TI** • Matterport — fast visual documentation and virtual tours • LiDAR — accurate existing conditions and Scan-to-BIM • Depth cameras / photogrammetry — specialized or lower-cost capture **Large Interiors — Commercial, warehouse, hotel, healthcare, data center, multifamily, industrial** • Mobile LiDAR/SLAM — efficient large-area capture • Terrestrial laser scanning — high-accuracy/critical areas • Matterport — visual documentation and walkthroughs • Hybrid mobile + static scanning — speed + accuracy **Small Exteriors — Homes, façades, roofs, individual buildings** • Terrestrial LiDAR — accurate building/façade geometry • Drone photogrammetry — roofs and inaccessible areas • Hybrid drone + ground scanning — complete coverage **Large Exteriors / Sites — Campuses, construction sites, industrial facilities, acreage** • Drone photogrammetry — site mapping, orthomosaics and 3D reconstruction • LiDAR/mobile mapping — ground-level structures and geometry • GNSS/RTK/control — georeferenced mapping • Aerial + terrestrial capture — complete site/building coverage My goal is to recommend the **fastest and most cost-effective technology that actually meets the required accuracy** rather than automatically specifying the most expensive scanner. ## SCAN-TO-BIM / POINT CLOUD TO MODEL Scanning can include the finished BIM/CAD deliverable. Services include: • Point Cloud to Revit / Scan-to-BIM • Existing-condition BIM models • Architectural, structural & MEP modeling • Floor plans, elevations & sections • Façade and building-envelope modeling • CAD/as-built documentation • Point-cloud registration & alignment • Model-to-scan comparison • Construction coordination models • Digital-twin/spatial-data preparation LOD and modeling scope can be tailored to the actual project requirements to avoid unnecessary modeling cost. ## MATTERPORT Matterport is ideal when fast visual documentation and remote navigation are more important than survey-level accuracy. I can provide Matterport capture, virtual walkthroughs, construction documentation, existing-condition surveys, MatterPak workflows, and integration with BIM/reality-capture workflows. I can also advise when **Matterport is NOT the right tool** and LiDAR, photogrammetry, or another solution is more appropriate. ## DRONE MAPPING & PHOTOGRAMMETRY Drone capture can support: • Construction/site mapping • Roof and façade documentation • Orthomosaics • Photogrammetric point clouds • 3D reconstruction • Progress documentation • Integration with terrestrial LiDAR and BIM ## LiDAR / DEPTH CAMERA / SLAM SYSTEM DEVELOPMENT I also help startups, developers, researchers, and product teams build or troubleshoot their own **3D scanning and spatial-mapping equipment**. Experience includes: • LiDAR, stereo & RGB-D/depth cameras • Global-shutter and multi-camera systems • IMUs and GNSS/RTK • NVIDIA Jetson • ROS / ROS 2 • SLAM, VIO & LIO • Computer vision • Point-cloud processing • Sensor fusion • Hardware synchronization • Camera/IMU/LiDAR calibration • Sensor coordinate transforms I can assist with **sensor selection, system architecture, hardware/software integration, calibration, synchronization, SLAM integration, field testing, troubleshooting, validation, and prototype development.** I have worked with technologies from **Leica, FARO, Trimble, NavVis, GeoSLAM, Matterport, Emesent, Gexcel, GreenValley, Dot3D, Kaarta, RoboSense, Orbbec, Luxonis, and related platforms.** Whether you need a **small property scanned, a large facility mapped, a site captured by drone, a point cloud converted to Revit, or help developing a new LiDAR/depth-camera mapping device**, I can help select the right approach and carry it through to a usable deliverable.
