Surveying - Siegfried Engineering

Precision is everything. Our survey team delivers accurate, reliable results from the start, so projects move forward with confidence. Combining advanced GPS and TPS technology with real-world expertise, we provide the critical data needed to build smarter.

From aerial and field surveys to boundary resolution and legal descriptions, our team has the experience to support a wide range of projects. We also specialize in underground utility and mechanical detection surveys, record surveys, and tree surveys—ensuring no detail is overlooked.

With a direct link between our field crews and in-house designers and engineers, we keep communication seamless and results precise. By capturing a clear and exact picture of existing conditions, we help our clients make informed decisions and move forward with solutions tailored to their project needs.
