Specialists in Surveys for Highway Upgrades, Safety Schemes & Infrastructure Improvements

At Kemp, we provide precise and dependable Highway Improvement Surveys to support the planning, design, and delivery of road-based infrastructure. From local junction upgrades to large-scale corridor improvements, our surveyors capture the accurate data engineers need to design safer, more efficient highways.

Whether you’re delivering traffic management upgrades, active travel schemes, resurfacing programmes, drainage improvements, or major road realignment, we ensure every measurement is correct, complete, and ready for design.

Trusted by Local Authorities, Consultants & Major Infrastructure Teams

Over decades in the sector, we’ve supported some of the South West’s most recognised highways and civil engineering teams. They rely on our surveys because we:

  • Deliver highly accurate topographic and corridor data
  • Understand the complexities of live highway environments
  • Provide flexible support from rapid data capture to full scheme surveys
  • Work seamlessly with designers, contractors, and local authority engineering teams

Why You Need Professional Highway Improvement Surveys

Highway improvement projects demand precise, reliable survey data to avoid delays, design changes, and costly rework. With professional surveyors on your team, you can be confident that:

  • Existing carriageway and verge features are mapped correctly
  • Levels, drainage, utilities, and structures are captured accurately
  • Traffic-sensitive environments are surveyed safely and efficiently
  • Designers receive robust data to develop compliant, buildable solutions

Even minor inaccuracies can have major consequences during construction; our surveys ensure a smooth path from design to delivery.

Decades of Experience in Highway & Infrastructure Surveying

Since 1988, Kemp has provided specialist surveying services across the South West and beyond, supporting a wide range of highway and infrastructure projects. 

Our teams have worked on highway realignments, cycleway and pedestrian improvement schemes, junction redesigns and safety enhancements, as well as bus priority and active travel routes. 

We have also delivered detailed surveys for drainage upgrades, flood-mitigation works, and major trunk road projects for national infrastructure clients. With more than three decades of experience, there are very few highway environments we haven’t surveyed.

Our Highway Improvement Surveys Process

Our approach is adapted to the scale, constraints, and traffic conditions of each project. A typical workflow includes:

We begin by understanding the scheme requirements and reviewing any design constraints as well as the traffic-management considerations needed to carry out the work safely and efficiently.

Our team conducts a full desktop review, carries out utility searches, and prepares all traffic-management and safety planning necessary ahead of the survey.

We establish accurate GNSS and total-station control across the site and verify all benchmarks and datums to ensure a precise survey framework.

We then capture detailed survey data including carriageways, footways, and verges, along with kerbs, signs, barriers, and other street-furniture features, as well as levels, drainage networks, utilities, and structures.

After capture, we process the information into CAD files and 3D terrain models, delivering the data in whichever formats your design team requires.

As the project evolves, we provide updated survey information and carry out additional data capture whenever design changes or new requirements arise.

All work undergoes rigorous internal checks and is delivered in line with our ISO 9001 certified quality-management processes.

Areas We Cover

Our engineers operate daily across the South West, covering Cornwall, Devon, Somerset, and Dorset. We also regularly support projects beyond the region for national infrastructure clients.

Whether you require a small junction survey or a full highway corridor scheme, our teams mobilise quickly and safely.

Highway Improvement Surveys FAQs

A Highway Improvement Survey typically includes detailed topographic data of the carriageway, footways, verges, kerbs, street furniture, drainage features, utilities – if required our Seeka team can carry these out at surface or sub-surface level, structures, and surrounding land. It provides designers with accurate levels, feature positions, corridor widths, and all spatial information required to develop upgrade, safety, or realignment schemes.

Yes, we regularly work on live highways and follow strict safety protocols to ensure safe data capture. Our teams are trained for highway environments and operate in accordance with industry standards, supported by appropriate traffic management and risk assessments.

We can arrange traffic management where required, from simple signage and lane closures to more complex road-space bookings. This ensures we can survey safely, efficiently, and in compliance with local authority and national guidelines.

Absolutely. We can deliver survey data in BIM-compatible formats and produce detailed 3D terrain models, point clouds, and digital design files to support modern, model-based workflows.

Yes, our Seeka team survey utilities and drainage systems as part of highway improvement work. We can capture visible features, lift covers where permitted, trace routes, record invert levels, and integrate PAS 128 utility mapping where required. We can also provide HADDMS surveys.
