Services
Civil Engineering
Sam O Hirota provides comprehensive civil engineering services, including master planning, drainage studies, FEMA permitting, and infrastructure design. Our expertise ensures projects meet regulatory standards while addressing client-specific needs. With decades of experience, we deliver cost-effective, timely solutions for roads, utilities, and public works.
Land Surveying
Our land surveying services encompass boundary analysis, topographic mapping, and ALTA surveys. Utilizing advanced tools like RTK GPS and 3D laser scanners, we ensure survey-grade accuracy. Projects range from residential lots to large-scale government installations, emphasizing precision and reliability.
Aerial LiDAR
Aerial LiDAR and photogrammetry services capture high-resolution geospatial data for terrain analysis and 3D modeling. Our UAV operations support infrastructure planning, volumetric calculations, and asset inspections, combining aerial data with ground verification for comprehensive results.
3D Laser Scanning
3D laser scanning creates detailed digital twins of buildings and sites. Applications include historical preservation, MEP modeling, and urban planning. Our scanners capture millions of data points, enabling precise documentation and change detection for maintenance and development projects.
Scan to BIM
Scan-to-BIM converts laser-scanned point clouds into intelligent Revit models for building management. This process supports facility maintenance, retrofitting, and asset tracking. Partnering with specialists, we ensure models reflect real-world conditions for government and private clients.
