Land & Engineering Surveyors Yorkshire
High accuracy 3D Laser scanning services
Tri-Tech provides professional 3D laser scanning survey services for construction, engineering, architecture, and infrastructure projects across Yorkshire and the wider UK.
Laser scanning has become one of the most powerful tools in modern surveying. By capturing millions of precise measurements to create a highly detailed digital record of land, buildings, and complex environments, architects, design teams and project managers can
Whether you require topographical laser scanning, measured building surveys, or BIM-ready point clouds, our team delivers accurate, reliable data tailored to your project requirements.
What is a Laser Scanning Survey?
Laser scanning (also called 3D laser scanning or LiDAR) uses pulsed laser technology to rapidly collect millions of highly precise spatial points. These points form a dense 3D point cloud, capturing the physical world in exceptional detail – from terrain and structures to complex infrastructure.
Unlike conventional methods that record individual measurements manually, laser scanning gathers comprehensive spatial data in a fraction of the time with excellent accuracy and efficiency.
Terrestrial laser scanning captures a 360° sweep from a stationary setup, firing millions of laser pulses to build a detailed point cloud of the surrounding environment.
Ideal for:
- Measured building surveys
- Detailed architectural documentation
- Structural condition mapping
- BIM model foundations
SLAM scanners are mobile, allowing surveyors to walk through a space while capturing continuous 3D data.
Ideal for:
- Confined or intricate interior spaces
- Industrial facilities
- Areas with obstructed access
LiDAR sensors mounted on drones fire thousands of laser pulses per second, measuring return time to build accurate representations of large areas from the air.
Ideal for:
- Large or uneven terrain
- Vegetation-penetrating surveys
- Terrain models and corridor capture
Why Do You Need a Laser Scanning Survey?
Laser scanning delivers a fast, safe, and highly accurate method of capturing existing site conditions. It is ideal for:
- Complex construction environments
- Large-scale topographical mapping
- Refurbishment and retrofit projects
- Infrastructure and asset management
- Design coordination and BIM workflows
Why Laser Scanning Matters
Laser scanning revolutionises survey data collection by offering:
SPEED
Capture complex environments far faster than traditional methods.
Accuracy
Millimetre-level precision for detailed modelling and analysis.
Safety
Data captured from a distance reduces need for access to hazardous areas.
Coverage
Hard-to-measure features are recorded in dense 3D point clouds.
What Will You Receive from a Laser Scanning Survey?
When you commission a laser scanning survey with Tri-Tech, you receive accurate, design-ready digital data that can be used immediately for planning, modelling and construction.
Depending on your project requirements, typical deliverables include:
Point Cloud (LAS, E57, RCP)
2D CAD Drawings (DWG/ DXF)
PDF plans and elevations
3D mesh models and surfaces
BIM & Revit-ready deliverables
Contour, volume and terrain analysis

What is Laser Scanning in Surveying?
Laser scanning, also known as lidar (Light Detection and Ranging), is a surveying technology that uses laser beams to accurately measure the distance, shape, and
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.
setting out & site engineering
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.
measured building 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.
3d machine control
Machine control systems have been around for years now and Tri-tech have been utilising these systems from the very start. We realised the benefits of these systems early on when working with earthworks contractors.
survey equipment hire
Being a leader in the Surveying and Engineering sector we have a fleet of modern survey equipment at our disposal which is second to none. We carry the latest GNSS Base Stations, GNSS Rovers, Robotic Total Stations, Laser Scanners, Digital Levels, and Dual Grade Lasers.
BIM Model Creation
BIM (Building Information Modelling) model creation in surveying refers to the process of using specialised software to create a 3D digital model of a building or infrastructure project that includes information about the project’s design, construction, and maintenance.
Virtual Tour 3D
