Our Engineering Survey Process
Our engineering survey process begins with careful planning and coordination. We work closely with project teams, reviewing design drawings, specifications, and site conditions to ensure every detail is captured with accuracy and efficiency. This preparation allows us to anticipate challenges and deliver survey results that support smooth project execution.
​
Once on site, our skilled survey crews and technologists leverage advanced GNSS, robotic total stations, and 3D scanning technologies to collect data with precision. From setting project control to final deliverables for highways and bridges to utilities and building sites, we provide the high-quality survey information that engineers, architects, and contractors rely on to make informed decisions.
Types of Surveys
Our services support the full project lifecycle, from initial site data collection to detailed survey control for complex infrastructure and engineering design.
Topographic Surveys
We capture detailed information about the land surface, including elevations, contours, and existing features such as buildings, roads, and utilities—providing a reliable foundation for design and planning.
Engineering Surveys
Our surveys support a wide range of engineering projects, delivering accurate field data required for site design, infrastructure planning, and project development.
Digital Terrain Models (DTMs) & Surface Data
We process survey data into clean, structured digital terrain models that integrate seamlessly into engineering and design software, improving efficiency and accuracy.
Geodetic Control Surveys
For large-scale or high-precision projects, we establish geodetic control networks that ensure consistency and accuracy across all phases of design and construction.
