Surveyor – The Licensed Professional Conducting Surveys

A surveyor is a highly trained and licensed professional dedicated to the science and art of measuring, mapping, and documenting the Earth’s features and built environments. Surveyors play a pivotal role in land development, construction, real estate, and aviation by providing the authoritative determination of property boundaries and spatial data essential for legal, financial, and operational decision-making.

Surveyors are responsible for interpreting complex legal descriptions, reconciling discrepancies between historical records and current site conditions, and preparing certified plats and documentation used in property transactions and court cases. Their expertise ensures that structures and infrastructure are built in the correct location and comply with all regulatory and legal requirements.

Core Responsibilities

• Boundary determination: Establishing and re-establishing legal property lines, resolving disputes, and preventing encroachments.
• Legal documentation: Preparing plats, legal descriptions, and reports for deeds, titles, mortgages, and regulatory agencies.
• Topographic and as-built mapping: Providing detailed maps of land features, structures, and utilities for design, construction, and asset management.
• Construction layout: Translating design plans into physical markers on site to guide building, infrastructure, and utility placement.
• Specialized surveying: Supporting floodplain management, aviation safety, digital modeling, and historic preservation through precision measurement.

Surveyors must meet rigorous academic and practical experience requirements, pass state or national licensing exams, and adhere to strict codes of ethics and legal standards. Their certified work is recognized as legally binding and is relied upon by courts, government agencies, developers, engineers, and property owners.

What is Surveying?

Surveying is a precise scientific and professional discipline encompassing the measurement, representation, and analysis of natural and built environments. Its primary aim is to determine the relative positions of points, lines, and structures on the land, water, or in three-dimensional space, and to document these findings for a wide range of legal, design, and regulatory purposes.

Surveying combines mathematics, physical science, law, and technology. Surveyors use methods ranging from traditional triangulation and leveling to state-of-the-art GNSS, laser scanning, and photogrammetry. Deliverables include boundary surveys, topographic maps, digital terrain models, and legal descriptions that underpin property rights, engineering projects, and government records.

Surveying is indispensable in aviation, ensuring accurate plotting of runways, taxiways, and navigation aids in compliance with ICAO Annex 14 and FAA standards. Survey data supports safe airport operations, obstacle management, and regulatory certification.

Types of Surveys and Their Applications

Title/Asbuilt Survey

A Title/Asbuilt Survey documents property boundaries, structures, and improvements at a specific point in time, verifying that legal descriptions match on-the-ground conditions. Common in property transactions and refinancing, these surveys reveal encroachments, easements, and discrepancies that affect ownership or use.

Title/asbuilt surveys are vital in urban settings, where properties and structures are closely spaced, and are required by title insurers and lenders to clear risks before closing. In aviation, asbuilt surveys document the exact location of runways, taxiways, and buildings for regulatory compliance and future planning.

ALTA/NSPS Survey

An ALTA/NSPS Survey is the gold standard for commercial property due diligence. Governed by national standards, it includes exhaustive research of public records, field measurements, and the identification of all matters affecting title and use, such as easements, encroachments, and zoning restrictions.

ALTA/NSPS surveys are critical for buyers, lenders, and title insurers in high-value transactions, and are often required in aviation projects for airport land acquisition and FAA compliance.

Topographical Survey

A Topographical Survey provides a detailed 3D map of land surfaces, showing contours, elevations, and all natural and man-made features. These surveys inform design decisions in site development, engineering, floodplain management, and environmental assessments.

Topographic data is essential in aviation for obstacle limitation studies, runway design, and safeguarding airspace as required by ICAO standards.

Stakeout Survey

A Stakeout Survey (construction layout) translates design drawings into physical points and markers on site, guiding the precise placement of foundations, utilities, roadways, and other features. Surveyors ensure that every element is built to the correct location and elevation, preventing costly errors and ensuring regulatory compliance.

In aviation, stakeout surveys are crucial for the proper installation of runway lights, navigation aids, and signage.

3D Scanning Survey

3D Scanning Surveys use laser scanning or photogrammetry to produce high-resolution, three-dimensional digital models (point clouds) of sites and structures. These are invaluable for documentation, renovation, digital twin creation, and analysis of complex geometries.

Aviation projects use 3D scanning for accurate mapping of terminals, runways, and terrain, supporting safety and asset management.

Construction Survey

A Construction Survey spans all measurement and layout tasks required to ensure that construction happens in accordance with plans, specifications, and safety requirements. Surveyors monitor progress, verify elevations and alignments, and document as-built conditions for final certification.

Flood Elevation Certificate & LOMA

A Flood Elevation Certificate certifies the elevation of a building’s lowest floor relative to the base flood elevation, supporting flood insurance and compliance with FEMA and local regulations. A Letter of Map Amendment (LOMA) removes a property from a flood zone based on certified elevations.

Foundation As-Built Survey

A Foundation As-Built Survey verifies the location, dimensions, and elevation of a building’s foundation after construction and before further work, ensuring compliance with plans and regulatory setbacks.

Subdivision Survey

A Subdivision Survey divides land into new parcels or lots, establishing new boundaries, streets, and utilities in compliance with planning and zoning regulations. These surveys are key to real estate development and airport expansion projects.

Architectural Survey

An Architectural Survey delivers highly accurate measurements of existing buildings, facades, and interiors, supporting design, renovation, and preservation. Surveyors use traditional and advanced scanning techniques for detailed documentation.

Other Specialized Surveys

Surveyors also perform:

• Boring Location Surveys: For geotechnical or environmental drilling.
• Pile Layout Surveys: Marking deep foundation locations.
• Axis Lines/Anchor Bolt Layout: Setting reference lines and anchor points for industrial and infrastructure installations.
• Final Survey/Certificate of Occupancy: Verifying conformance to plans for occupancy certification.
• Accident Surveys: Documenting site conditions for legal or insurance purposes.
• Expert Testimony: Providing certified maps and analysis in court.
• GPS/GNSS Surveys: High-accuracy measurements for large or remote sites.
• FAA Application Surveys: Supporting airport regulatory submissions.
