Whether you're planning a new construction project, an addition, or simply need a clearer understanding of your property boundaries, our residential site surveys provide the essential data for informed decision-making.

If you're planning to divide a larger parcel of land into smaller lots for development, a precise and accurate subdivision plan is essential.

We ensure precise alignment and grading, minimizing delays and costly rework. Our accurate site measurements and staking are crucial for the successful completion of your construction project.

• Topographical Surveys:

Topographical surveys provide a detailed representation of the natural and man-made features of a site, including elevations, contours, and slopes. We create accurate topographic maps that are invaluable for design planning, construction, and land development projects. Understanding the terrain's contours is essential for safe and effective construction and landscaping.

• Elevation Certificates:

Elevation certificates are vital documents required for flood insurance purposes. Changes in flood plain regulations and FEMA flood maps necessitate regular elevation certifications. We accurately determine the elevation of your property, providing you with the necessary documentation for your flood insurance policy.

• ALTA Surveys:

ALTA survey is a specialized type of boundary survey conducted in accordance with the American Land Title Association (ALTA) standards. ALTA surveys are essential for real estate transactions, identifying potential boundary encroachment or easements. We conduct thorough ALTA surveys that meet the rigorous standards of the American Land Title Association.

• Ground Penetrating Radar (GPR):

GPR is a non-invasive geophysical technique that uses radar pulses to detect subsurface features, such as underground utilities, buried structures, and voids. We utilize advanced GPR technology to provide detailed subsurface information, assisting with project planning, avoiding potential damage to utilities during construction, and assisting in historical archaeology.
