Services
Boundary Surveying
Our boundary surveying services define property lines using high-tech equipment and deed research to ensure legal accuracy. We review historical records, easements, and physical markers to resolve disputes and establish clear ownership boundaries. Clients receive detailed maps and documentation for real estate transactions, development, or legal proceedings.
Topographic Mapping
Topographic mapping creates detailed 2D representations of land features using 3D data collection. We document contours, utilities, and natural elements to support construction planning and land development. This service helps minimize project costs while maximizing land use efficiency for architects and engineers.
FEMA Elevation Certificate
We provide FEMA elevation certificates required for flood insurance and building permits. Our licensed surveyors measure structure elevations relative to floodplains using GPS technology. This critical documentation ensures compliance with federal regulations and helps property owners reduce insurance costs.
Land Segregation
Our land segregation services facilitate legal property divisions through short plats, large lot divisions, and binding site plans. We navigate municipal requirements to create compliant parcel splits for residential or commercial development. This includes boundary adjustments and condominium conversions under state law.
Construction Services
We offer construction layout services using RTK-GPS and robotic total stations for precise building placement. Our team establishes benchmarks and monitors structural movement during development. These services ensure accurate implementation of engineering plans while maintaining compliance with local building codes.
