Topographical Surveys Yorkshire
Accurate Topographical Survey Services Across the UK
Tri-Tech Surveys provides high-accuracy topographical surveys for planning, design, and construction projects across Yorkshire and the wider UK. Our detailed land and terrain surveys capture all natural and man-made features, delivering precise data you can rely on for informed decision-making. Whether you’re preparing a planning application, designing infrastructure, or developing land, our experienced surveyors deliver clear, compliant, and reliable topographical survey outputs tailored to your project requirements.
What is a topographical survey?
A topographical survey is a detailed measurement and mapping of a site’s physical features and ground levels. It records both natural features such as contours, trees, and watercourses, and man-made features including buildings, roads, boundaries, and drainage. Accurate survey data reduces risk, improves design efficiency, and ensures compliance with planning and regulatory standards.
What we capture
Our topographical survey services
A topographic survey — also referred to as a land survey or topo survey — produces a detailed, accurate record of the physical features of a site. Ground levels, contours, boundaries, drainage, vegetation, structures, services at surface level and all contextual features within and around the survey area are captured and plotted to produce a georeferenced dataset that your design team can build on with confidence.
At Tri-Tech, we go beyond the industry standard on every survey we deliver. Sections, contours and intensity ramps are included as standard. Springs, subsidence, bodies of water and flood risk indicators are noted on every drawing. Where a 2D plan is not sufficient for the design brief, we produce 3D models, point cloud datasets and aerial overlays that give your project team a complete, measurable picture of existing conditions.
Every survey is OS-controlled, tied to National Grid, and delivered in the format your design software requires — AutoCAD DWG, Revit, GIS-compatible output, or a combination. In 2025 alone we completed over 950 topographic surveys across infrastructure, highways, regeneration and development schemes. The team that quotes your project is the team on site.
We believe that land surveying goes beyond mere measurements. To enhance our deliverables, we leverage the latest technology to provide additional features such as sections, contours, and intensity ramps throughout the site, all at no extra cost. Our drawings encompass a thorough documentation of all notable elements and limiting factors, including springs, subsidence, bodies of water, and more. At Tri-Tech we take pride in going above and beyond to ensure that our clients receive a comprehensive and detailed survey that meets their specific requirements.
All features are surveyed to the accuracy specified and delivered with a clear methodology statement confirming the equipment used, the coordinate system, the accuracy achieved and the date of survey. Using Trimble and CHCNAV instrumentation, our surveys are precise, efficient and consistent across the most challenging North East and Yorkshire environments.
Ground Levels & Spot Heights
A comprehensive grid of verified ground levels across the survey area, to the density your design requires.
Contours
Generated from the level data, at intervals specified for your project.
Boundaries
All visible boundary features including fences, walls, hedges, ditches and ownership boundaries where determinable.
Drainage
Surface drainage features, gullies, manholes, channels and watercourses within the survey area.
Vegetation
Trees with canopy spread, species and height where required; hedges, shrubs and ground cover.
Structures
All above-ground structures including buildings, retaining walls, kerbs, steps, ramps and highway furniture.
Services at Surface
Visible service indicators including manhole covers, inspection chambers, meter boxes and duct markers.
Contextual Detail
Adjacent features, road levels, footway widths, overhead features and anything else that informs the design brief.
We provide flexible outputs to suit architects, engineers, planners, and contractors:

Benefits of a Topographical Survey

How Topographic Surveys Integrate With Other Services
Topographic survey is most powerful when it is part of a coordinated data package. The most effective programmes combine topographic survey with complementary disciplines to give the design team everything they need from a single instruction. Topographic and PAS 128 utility mapping is the most common combination on construction and infrastructure programmes across Yorkshire and the North East. Ground truth above and below surface, delivered as a single georeferenced dataset. One instruction, one team, one output. Topographic and bathymetric surveys are used together when sites include watercourses, combining ground-based topographic survey with bathymetric data gives the design team a complete picture from bank to riverbed. Our River Nidd project is a direct example of this combined approach. Topographic and UAV surveys are for large sites, long corridors or environmentally sensitive terrain where ground-based survey alone is impractical, combining GPS-controlled ground survey with UAV-captured LiDAR or photogrammetric data produces a dense, accurate dataset across the full area rapidly. Our River Wenning erosion survey used exactly this approach. Topographic and laser scanning are used where complex structures, underground environments or heritage assets are involved, combining topographic ground survey with laser scanning delivers a complete record of the site from surface level to structural detail. Our Sunderland tunnel survey combined both disciplines in a confined underground environment. Topographic and BIM delivery is where a BIM requirement exists, we build the topographic survey scope around your EIR from the outset, producing data that integrates directly with your Revit or AutoCAD environment without reprocessing.
Land and Engineering Surveyors
topographical surveys
Tri-Tech work for a variety of different clients on different projects, and we pride ourselves on delivering accurate, efficient, cost effective surveys ensuring our clients receive the best possible product.
utility mapping
Using the latest equipment, we can provide the location of underground services in either 2D or 3D. We use state of the art Ground Penetrating Radar and Electromagnetic Location to assist your project when service avoidance may be a potential issue on site.
monitoring
Is there any movement? That is the question that is asked before and during any monitoring scheme. That is the reason we undertake monitoring, to check for movement.
laser scanning
For mass collection of accurate survey data then nothing beats scanning. Using 3D laser Scanners the surveyors can capture millions of points per second with the creation of a PointCloud.
volumetric analysis
We specialise in the analysis of a scheme’s volumetrics at any point in time. Be it Tender, Prestart, Monthly, Weekly, or Final.
Bathymetric surveys
By using the latest surveying technology, we have been able to survey watercourses safely and efficiently.

Bread and butter work for us! Having a strong relationship with many civil engineering companies we have a very strong team of Site Engineers and Engineering Surveyors working for us.
control network installation
At Tri-Tech we have vast experience in this field. Be it a large highway scheme or a private property we can advise on what accuracies are required from your control network depending on what work you are carrying out and the tolerances you are carrying this work out to.
uav mapping & aerial surveys
Large areas of ground can be covered capturing the most unbelievable detail which would just be unable to be recorded with traditional methods. Our clients have really seen the benefit of what UAV surveys bring to the table.
