About the firm
Accurate Infrastructure Data, Inc. (A|I|DATA) specializes in Subsurface Utility Engineering (SUE) and professional land surveying. It investigates, locates, and maps underground utilities, surface features, topography, and property lines for public, private, and institutional clients across the Mid-Atlantic region. Working in accordance with ASCE 38-22 standards, the practice delivers precise spatial data to prevent utility damage, avoid costly change orders, and streamline civil design projects.

Capabilities
Subsurface Utility Engineering
Service websiteProvides comprehensive investigation, locating, and mapping of underground utilities combining civil engineering, surveying, and geophysics to manage design-phase risks.
- Utility Records Research
Gathers and analyzes historical records and utility owner documentation to build a comprehensive inventory of existing systems before site work begins.
- Surface Feature Correlation
Surveys visible aboveground utility facilities and structures, correlating findings with existing utility records.
- Surface Geophysical Prospecting
Utilizes electromagnetic detection instruments and ground-penetrating radar to trace conductive and non-conductive utility lines and detect undocumented systems.
- Nondestructive Test Hole Excavation
Employs vacuum excavation and other nondestructive digging methods to expose utilities at critical points, resolving precise vertical and horizontal positions.
Land Surveying
Service websiteDelivers professional geomatics and mapping solutions to establish precise site control, document property boundaries, and support land development projects.
- Control Surveys
Establishes highly accurate horizontal and vertical reference networks to set the foundation for site design and construction activities.
- Topographic Surveys
Generates detailed maps of site terrain, contours, and physical features to help developers identify design possibilities and physical constraints.
- Boundary and Property Surveys
Researches legal deeds and recovers physical documentation to reestablish precise property lines, rights-of-way, and easement boundaries.
- ALTA/NSPS Land Title Surveys
Performs comprehensive property surveys adhering to strict national standards to assist commercial transactions, title insurance matters, and acquisitions.
- As-Built and Record Surveys
Verifies the final horizontal and vertical positions of completed physical improvements against their original design documentation.
- Platting and Easement Mapping
Prepares legal plats and descriptions for subdivisions, easements, condominiums, lot line adjustments, and rights-of-way.
