Services
Land Surveying
Our land surveying services utilize advanced tools like GPS and 3D scanning to establish precise property boundaries, easements, and topographic features. We support real estate transactions, construction projects, and legal dispute resolution by delivering accurate, code-compliant data. Clients rely on our licensed professionals for boundary surveys, platting, and utility mapping across 20+ states.
Civil Engineering
We provide full-cycle civil engineering for site development, including stormwater management, roadway design, and utility systems. Our team ensures compliance with municipal regulations while optimizing project feasibility through hydraulic analysis and sustainable practices. Expertise spans commercial, healthcare, and educational facility projects with integrated entitlement support.
3D Laser Scanning
Using Trimble X7 technology, we capture high-definition 3D point clouds for as-built documentation and design integration. This non-invasive method reduces rework by providing millimeter-accurate data compatible with AutoCAD and BIM software. Applications include structural analysis, construction layout, and historical site preservation projects.
Aerial Photogrammetry
Our DJI Mavic 3 drones create detailed topographic maps and 3D models for large-scale sites. This technology accelerates data collection in challenging terrains while maintaining survey-grade accuracy. Clients use these deliverables for pre-construction planning, progress monitoring, and environmental impact assessments across energy and infrastructure projects.
Utility Surveys
We locate and map underground utilities including water, gas, and telecom lines to prevent conflicts during construction. Our process combines ground-penetrating radar with regulatory database research to ensure safe, compliant project execution. This service reduces costly delays while supporting municipal infrastructure upgrades and private development projects.
