What Is Surveying? Understanding the Profession
Surveying is the science and art of determining the three-dimensional positions of points and the distances and angles between them. These points are typically located on, above, or below the Earth’s surface. Surveyors use this information to establish land boundaries, assist in construction projects, and create maps and charts.
The profession combines elements of mathematics, physics, engineering, and law to provide accurate measurements and data that form the foundation for countless projects and legal decisions. Surveyors are often the first professionals on a construction site and the last to leave, ensuring everything is built according to plan.
Key Functions of Surveying
- Establishing precise property boundaries
- Creating accurate maps and site plans
- Providing data for construction and engineering
- Monitoring structural movements and deformations
- Ensuring compliance with legal and regulatory requirements
- Supporting land development and infrastructure projects
Key Responsibilities of Surveyors
Surveyors perform a wide range of tasks depending on their specialisation. However, certain core responsibilities are common across the profession:
Measurement & Data Collection
Surveyors take precise measurements of land, buildings, and other structures using specialised equipment. They collect data on distances, angles, elevations, and positions to create accurate representations of physical spaces.
Analysis & Interpretation
Once data is collected, surveyors analyse and interpret the information to create maps, plans, and reports. This process involves applying mathematical principles and using specialised software to process raw measurements.
Documentation & Reporting
Surveyors prepare detailed reports, maps, and plans that document their findings. These documents serve as legal records and provide essential information for property transactions, construction projects, and land development.

What Do Surveyors Look for in House Surveys?
When conducting residential property surveys, surveyors examine numerous aspects of a building to assess its condition and identify potential issues:
External Inspection
- Roof condition and structure
- Exterior walls and cladding
- Windows and doors
- Guttering and drainage
- Chimney stacks and other roof features
- Boundary walls, fences, and outbuildings
Internal Inspection
- Walls, ceilings, and visible structural elements
- Signs of damp, condensation, or water damage
- Evidence of subsidence or structural movement
- Loft spaces and accessible areas
- Floors and staircases
- Visual assessment of services (electrical, plumbing, heating)
The depth of inspection varies depending on the type of survey commissioned. From basic condition reports to comprehensive building surveys, surveyors adapt their approach based on the property’s age, condition, and the client’s requirements.
