Services
Land Surveying
Our comprehensive land surveying services cover geodetic control, boundary analysis, and topographic mapping for infrastructure projects. With GPS technology and traditional methods, we deliver precise data for roadway expansions, utility installations, and property development. Our team maintains TxDOT precertification in multiple technical categories to ensure compliance with state standards.
3-D Scanning
We employ terrestrial and mobile LiDAR systems for high-accuracy 3D data collection. This technology enables safe, efficient surveys of transportation corridors, bridges, and complex infrastructure. Our scanning solutions support construction verification, as-built documentation, and digital terrain modeling for engineering applications across public and private sectors.
Construction Surveys
Our construction survey services include staking, alignment verification, and quality assurance for civil infrastructure projects. We support roadway development, utility installation, and building construction with real-time data validation. Our QA/QC processes ensure adherence to design specifications throughout project execution phases.
Floodplain Studies
We conduct detailed floodplain mapping and hydrographic surveys following FEMA guidelines. Our work includes streambank analysis, drainage studies, and watershed modeling to support flood risk assessment. These surveys inform infrastructure planning and regulatory compliance for municipal and federal agencies.
Aerial Mapping
Our aerial mapping services combine traditional surveying with modern photogrammetry techniques. We create detailed topographic models from aerial imagery for large-scale infrastructure projects. This approach supports efficient data collection for transportation corridors, utility routes, and urban development planning.
