Accurate Surveying Yorkshire, operating nationwide
Accurate Survey Control Networks Across the UK
Based in Yorkshire, Operating Nationwide
A reliable control network is the foundation of every successful engineering and construction project. Without accurate survey control points, setting out, machine control, laser scanning and as-built surveys can all be compromised.
Tri-Tech provides professional control network installation services across Yorkshire and the wider UK, delivering robust and precise site control systems that ensure your project is built accurately from day one.
Whether you are starting a new development, infrastructure scheme or major earthworks project, our team establishes dependable survey control that supports every stage of construction.
What Is a Control Network?
- Setting out works
- Machine control calibration
- Laser scanning registration
- Topographical and as-built surveys
Why Control Network Installation Is Essential
- Maintain accuracy across large or complex sites
- Prevent dimensional errors and costly rework
- Ensure consistent positioning for all contractors
- Support GPS and machine guidance systems
- Provide long-term reference throughout the project lifecycle
Getting site control wrong can affect the entire scheme – which is why expert installation is critical.
Our Control Network Services
Tri-Tech delivers control solutions tailored to your project requirements, including:
Primary & Secondary Site Control
We establish robust primary control points and extend secondary control across working areas to support daily construction activities.
GPS & GNSS Control Networks
Using high-accuracy GNSS systems, we install coordinate control suitable for large-scale infrastructure and earthworks projects.
Total Station Control & Traversing
For projects requiring tighter tolerances, we use total station traverses and closed-loop networks to achieve maximum precision.
Machine Control Site Calibration
Control networks are essential for machine guidance. We ensure your site calibration is correct and fully aligned with design coordinates.
Monitoring & Control Verification
We can re-check and verify control throughout the project to ensure stability and ongoing accuracy as works progress.
Tri-Tech provides professional control network installation across a wide range of industries and project environments. Our survey control solutions are tailored to meet the technical demands of each sector, ensuring accuracy, consistency and long-term reliability. This sector experience ensures we can deliver the right control solution for your project – regardless of size, complexity or environment. We regularly install control networks for:
Supporting highways, bridges, drainage schemes and large-scale infrastructure where precise site control is critical.
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
Providing robust site control for plot setting out, roads, utilities and phased housing developments.
High-accuracy control for rail corridors, stations, depots and transport infrastructure projects.
Specialist control networks for runway paving, slipform operations and high-tolerance airport construction.
Control frameworks for large earthmoving projects, enabling machine control calibration and accurate cut/fill operations.
Survey control for pipelines, substations, service installations and PAS 128 utility coordination.
Applications of Survey Control Networks
- Civil engineering and highways
- Residential and commercial developments
- Rail and infrastructure schemes
- Airport and paving projects
- Earthworks and bulk excavation
- 3D machine control and digital construction
Wherever accurate positioning is required, control networks provide the essential foundation.
Deliverables & Documentation
- Control point schedules
- Coordinate reports
- Site control drawings
- Calibration documentation
- Integration with CAD and machine control systems
All control is delivered in line with project specifications and industry best practice.
Benefits of a Professionally Installed Control Network
- Reliable and repeatable site accuracy
- Reduced risk of setting out errors
- Improved coordination across contractors
- Strong foundation for digital construction workflows
- Confidence that your site is aligned correctly from the outset

What is a Control Network Installation?
A control network installation is a system of survey control points and benchmarks established on a construction site to provide a common reference system for
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
Virtual Tour 3D is an immersive experience which instantly transports your clients to your business, and guides them through your space, creating a seamless and captivating experience.
