Survey + Geospatial

Beyond measure… The expertise to capture the information you need

Our experienced team of surveyors and geospatial specialists has expertise and technologies to capture the information you need. Because CEC is a diverse, multi-disciplined firm, our specialists work collaboratively alongside engineering and environmental professionals to streamline the design, permitting, and construction processes for larger, multi-phased projects. We can mobilize team members from our offices nationwide to accommodate the requirements of complex projects and tight deadlines.

Our multidisciplinary specialists have broad experience across numerous projects requiring topographic, boundary, construction, hydrographic, scanning, and Unmanned Aerial Vehicle (UAV) aerial surveys (and we still use tape measures, too).

Far-reaching resources for gathering site data

Staffed with licensed Professional Land Surveyors, FAA-licensed and certified UAV pilots, terrestrial and mobile LiDAR specialists, experienced bathymetric/hydrographic surveyors, and a deep bench of support staff, our team has the expertise and technology to collect and deliver data in 3D and 2D formats for a variety of design, analysis, or documentation purposes.

We maintain a full complement of technology, including: 3D LiDAR scanners in ground-based, mobile, and UAV configurations; RTK-equipped fixed-wing and quadcopter UAVs; ultra-high-resolution and 360-degree digital cameras; survey-grade GPS, robotic, and scanning Total Stations; digital levels, data collectors, and mapping-grade GPS units; and autonomous and manned watercraft equipped with dual-frequency and side-scan sonar equipment.
