GHA: Navigating the Future with State-of-the-Art Land Surveying

At Gewalt Hamilton Associates, our Land Surveying Division blends traditional expertise with cutting-edge technology, ensuring unparalleled accuracy and innovation in our services. From boundary surveys to complex topographic conditions, we handle every project with adaptability and precision.


Land Surveying is the unsung hero of civil engineering. Given the critical importance of precision and comprehensive detail in our work, it is vital for surveyors to utilize state-of-the-art equipment, while adhering to industry standards and best practices for high-quality deliverables. We pride ourselves on utilizing state-of-the-art precision equipment in our surveying practices including total robotic stations, GPS units, drones, and our CUES SPiDER Manhole scanner. Our commitment to employing the latest in surveying technology, including tablet-controlled interfaces and cable-free designs, positions us at the forefront of innovative and efficient surveying services.

Our land surveying services cover a broad spectrum, from accurately locating property boundary lines for municipal boundaries, road rights-of-way, residential lots, commercial developments, and farms, to conducting specialized surveys in sectionalized areas, riparian surveys along rivers and lakes, and State line surveys. In addition to boundary surveys and plats of subdivision, we also provide ALTA/NSPS Land Title Surveys. Utilizing the latest technologies and equipment, we ensure no boundary challenge is too big or complex. Each project benefits from our attention to detail and deep understanding of land measurement principles.

Our expertise in transforming initial design concepts into their fully realized, three-dimensional realities extends across diverse projects, including highway improvements and stormwater management systems. Utilizing advanced surveying equipment and computer modeling, we ensure accuracy and efficiency in every layout. Our strength lies in effective communication and coordination, ensuring seamless integration of design and construction, and the successful transformation of visionary concepts into functional structures.


Drones have modernized land surveying, and at GHA, we incorporate this evolving technology into our wide range of surveying services. Our drone surveys provide high-resolution aerial photography and detailed data collection, enhancing the scope and accuracy of our services. Andrew Szendala, Survey Crew Chief, explains, “The aerial perspective we gain from drone surveys is invaluable, offering a comprehensive view that traditional methods can’t match.”
