At Kemp Chartered Land & Engineering Surveyors, we provide accurate and reliable machine control models for excavators, graders, dozers, and pavers. Our team has been working with GPS and 3D machine control technology since the early 2000s, giving us the expertise to deliver models that maximise accuracy and efficiency on site.
We produce tailored outputs for the three leading systems, Leica, Topcon, and Trimble, and our rigorous QA ensures that operators can switch between machines with confidence.
From major civil engineering schemes to residential developments, contractors and plant operators across the UK trust us to deliver precise, dependable models. Our clients value that we:
Machine control is transforming the way contractors work. Instead of relying solely on traditional setting out, operators use GPS-enabled plant to excavate and grade to design in real time. The benefits include:
Our team first worked with machine control on the M6 Toll Road in 2002, when the technology was still new to the UK. Since then, we’ve supported projects of every scale, from bulk earthworks and infrastructure to housing sites, commercial developments, and utilities. We’ve seen how the technology has evolved, and we’re proud to help contractors adapt to the future of construction.
We begin by reviewing all available project information, including engineering drawings, digital design models, specifications, and phasing plans. We also confirm:
The plant you are using (excavators, dozers, graders, pavers).
The control systems on site (Leica, Trimble, or Topcon).
Any site-specific constraints, tolerances, or design features requiring special attention.
This early clarity ensures the digital models we build are optimised for your machinery, workflow, and technical requirements.
Using the reviewed data, we create detailed 3D design models tailored to the needs of machine operators and the equipment they use. Our models may include:
Bulk earthworks and cut/fill surfaces
Finished surfaces, formation levels, and subgrades
Drainage networks, trenches, manholes, and sewer runs
Road alignments, kerbs, footways, and highway interfaces
Foundations, retaining structures, and platforms
We structure the model data to ensure smooth navigation, intuitive visibility for operators, and accurate representation of the design.
Before a model is issued, it undergoes detailed QA checks to confirm accuracy, geometry alignment, and compatibility with your chosen plant system. Our QA process includes:
Verifying levels, coordinates, and break lines
Checking design integrity across different surfaces or alignments
Ensuring layers, codes, and naming conventions follow a consistent structure
Testing for smooth transitions to avoid machine “jumps” or glitches
This gives plant operators confidence that they can work efficiently without unexpected errors in the field.
Once quality checked, we export the model to the correct format for your machine control technology:
Leica (iCON builds & MC1 compatible files)
Trimble (DSZ, TTM, PRO, etc.)
Topcon (TP3, TP5, TN3 formats)
We ensure that:
The file structure matches your site setup
All necessary reference files are included
The machine can load and interpret the model instantly
Where required, we can also assist with on-site installation or remotely upload new models directly to the plant cab.
Machine control isn’t a one-off service. Ground conditions change, designs evolve, and new plant arrives on site. We provide ongoing support throughout the project, including:
Regular accuracy audits to keep systems properly calibrated
Interim updates to the model as design changes are issued
Progress checks showing what has been cut, filled, or completed
As-built surveys to verify compliance with design levels
Remote troubleshooting for operators who need guidance
Our continued involvement ensures your machine control system performs consistently and supports efficient, accurate construction from start to finish.
Our engineers are based across the South West of England, but we deliver machine control support nationwide. Whether you need long-term assistance on major civil engineering schemes or one-off models for local projects, Kemp can provide a reliable solution.
At Kemp, we stand apart from other machine control providers because of our:
Machine control uses GPS or total station and 3D digital models to guide the drivers of plant machinery such as excavators, dozers, and graders. It allows operators to dig, grade, and build directly to design without relying solely on manual setting out.
Machine Control provides live positional data, allowing operators to see in real time whether they are cutting or filling to the correct level. This greatly reduces human error and rework.
Yes. We provide models compatible with Leica, Topcon, and Trimble systems, ensuring smooth integration with your current machinery.
Machine control is used on bulk earthworks, highways, drainage, foundations, retaining walls, attenuation tanks, residential developments, and commercial builds of all sizes.
Yes, if you provide us with the appropriate access we can load models directly to the cab from our office.
