When accuracy matters and projects require reliable results the first time, our team of surveyors excels. Siegfried delivers detailed surveys you can build upon by using the advanced capabilities of GPS and TPS combined with the human insight and experience needed to apply these tools.

From aerial and field surveys to boundary resolution and legal descriptions, our range of surveying capabilities provides clients with a significant depth of experience and expertise. We also have experience with underground utility and mechanical detection surveys, record surveys, and tree surveys.

The direct link to Siegfried’s field crews streamlines our design process and ensures accurate results by delivering a constant flow of communication between the survey crew in the field and designers and engineers in our offices. For our clients, having an exact picture of the existing conditions will allow our team to provide specific solutions tailored to their project.
