What Is A Topographical Survey

Essential Survey Details

A topographical survey, often referred to as a land, topo, or terrain survey, delivers a comprehensive and accurate depiction of a piece of land. It includes details about natural and man-made features, making it essential for accurate record-keeping and analysis.

Key Features Identified

This type of survey meticulously maps the contours, elevation, and physical characteristics of the terrain, along with the boundaries. It also documents any existing structures like buildings, roads, and other installations, providing a thorough understanding of the site’s layout.

Purpose and Importance

Topographical surveys are critical in the preliminary stages of construction and development projects. They supply vital information necessary for design and planning, ensuring that architects and engineers have a clear understanding of the site’s topography and features for informed decision-making.

At Safedigging Surveys, we have vast experience in carrying out topographic surveys. Our surveyors use Trimble S7 & S5 Robotic Total Stations as well as X7 & SX10 Robotic Laser Scanning Total Stations and Trimble R10 & R8S GPS receivers to carry out our surveys.

These instruments are also capable of reflectorless measurement, which means we can survey previously inaccessible points. This is particularly useful for surveying heights and positions of buildings, which overlook development sites and produce streetscapes of adjacent building elevations.

We also utilise UAV drone technology to help produce ground terrain models and topo surveys of large sites, this technology is again particularly helpful when access would normally not be possible. Safedigging Surveys also conducts topographical surveys using UAV/drone technology, Find out more today!

Understand

Why Do You Need A Topographical Survey

Topographical surveys help in determine the suitability of a site for a specific purpose, such as construction, infrastructure development, or environmental conservation. It can also identify a number of other potential issues on-site like slope instability, drainage problems, or environmental constraints that need to be addressed before any development takes place.  An accurate Topo survey is also required to be used as a Base drawing for a PAS128 Type B Utility Detection Survey.

Project Foundation

Topographical or land surveys establish the foundational accuracy for projects, ensuring precision from the beginning to effectively minimise risks and maintain control over dimensions.

Advanced Equipment

We employ state-of-the-art Trimble equipment, including S5 & S7 Total Stations, SX10 & X7 Robotic Laser Scanning, and R8S & R10 GNSS Systems, ensuring high accuracy in every survey.

Expert Team

Our team of experienced and fully qualified surveyors perform in-depth topographical surveys, accurately capturing every detail within the project area to ensure comprehensive utility mapping.

Data Processing & Integration

Using Trimble Business Centre Software (TBC), collected survey data is processed and integrated into N4CE and AutoCAD 2025, producing Safe-dig survey drawings in any format or tailored to client specifications.

Detailed Deliverables

We provide detailed 2D or 3D drawings that showcase the exact locations of static features like buildings and trees, complete with precise height levels and contours, aiding robust design and planning efforts.

Customisation & Standards

Every survey is customised to the project’s specific requirements, adhering closely to RICS standards and PAS128 specifications, ensuring a level of detail perfectly suited to your needs.
