Land Surveying & LiDAR Scanning

Our survey team’s goal is to develop the highest quality survey to meet the needs of our client in the shortest amount of time. We use cutting-edge technology and expertly-trained personnel to deliver efficient, reliable survey data.

In additional to our team’s professional land surveyors, CAD technicians, and LiDAR professionals, our diversified staff includes certified right-of-way agents, GIS professionals, and professional civil engineers. We use the latest software technologies to ensure accuracy and reduce office time on our survey field to finish process.

Our expertise includes topographic surveying for hydrology, design, and construction; LiDAR scanning and photogrammetry; right-of-way and construction staking; as-built, QA/QC, and quantity determination . Our field crews are trained in detailed data collection, and utilize a fully-customized field code library. Coordination with data processors and CAD technicians facilitates project needs.
