Services
A.L.T.A. Surveys
ALTA surveys provide standardized boundary determinations for lenders and title companies. Our team ensures compliance with national standards through meticulous deed research and precise field measurements. This service supports property transactions and development projects with legally defensible documentation.
Construction Staking
We deliver precise construction staking for public and private projects using digital plans and GPS technology. Our licensed surveyors ensure accurate placement of utilities and structures, minimizing rework and reducing project costs through expert field verification.
Subsurface Utility Scanning
Advanced ground-penetrating radar and electromagnetic methods identify hidden utilities without excavation. This service prevents infrastructure damage during construction by mapping underground systems when as-built records are unavailable or incomplete.
Photogrammetry
Aerial photography and digital orthophotos create detailed topographic maps for large sites. Our 2-3 week turnaround provides accurate base maps for design professionals, integrating seamlessly with CAD software for efficient project planning.
Potholing Services
Non-destructive vacuum excavation precisely identifies utility locations and materials. Using the Vacmaster 4000, we expose underground lines safely to prevent damage, ensuring worker safety and project compliance with regulatory standards.
