3D Engineering Surveys Limited

We are a premier engineering surveying consultancy with a 25-year track record of delivering high-precision data for the world’s most demanding infrastructure projects. From our roots in Exeter to our current headquarters in Bristol and our international offices in the UAE and the Philippines, we have grown into a global force of over 150 professionals.

Our mission is simple: to provide the intelligent data you need to build, manage, and relocate complex assets with absolute confidence. Whether you are managing a rail network in the UK or a petrochemical plant in West Africa, we bring the same level of RICS-regulated rigour to every millimetre we measure.

Why Global Infrastructure Leaders Trust Us

We don't just provide surveys; we provide certainty. Our team is directed by Chartered Surveyors and fully regulated by the Royal Institution of Chartered Surveyors (RICS). We operate under strict ISO 9001 quality standards, ensuring that every 3D model, topographical map, or monitoring report we produce meets the highest international benchmarks.

Specialists in Intelligent 3D Digital Twins

We lead the way in creating "Intelligent" 3D models that serve as living digital twins of your assets. By using the latest Leica TS20 total stations and advanced laser scanning technology, we capture every detail of complex environments like refineries and rail interchanges.

Our dedicated BIM processing department in the Philippines allows us to scale rapidly, turning raw scan data into sophisticated piping and structural models that integrate seamlessly into your design and maintenance workflows.

Revolutionising Plant Relocation with ExonTech

Through our sister company, ExonTech Engineering, we offer a service that is unique globally. We own and operate the only digital match-marking system designed specifically for plant relocations.

"We manage the entire lifecycle of a plant relocation—from dismantling and shipping to redesign and rebuild—ensuring every asset is tracked and every weld is accounted for."

This system uses our proprietary 'Asset Master' database to link every physical component to a 3D model, allowing for accurate rebuilding within budget and with minimal waste. Recent projects include the successful relocation of an Ammonia and Urea plant from the GCC to Nigeria.

Our Technical Capabilities

We stay at the cutting edge of the industry by constantly reinvesting in our fleet and our people. Our UAV department is fully CAA-authorized for aerial surveys, and our underground utility teams utilize the latest Ground Penetrating Radar (GPR) to map what cannot be seen. From dimensional control on high-speed rail to monitoring structural movement in power s
