Precision surveying,
grounded in expertise.

NJC Surveys provides accurate topographical surveys (also known as land surveys or site surveys) across the UK, from small residential plots and house extensions to large commercial and development sites. Our surveys map every key feature of your land, including boundaries, buildings, trees, levels, contours, drainage, manholes and services, giving architects, engineers and developers a reliable base plan for design and planning applications. Our experienced surveyors use the latest GPS and total station equipment to deliver precise data in CAD (DWG) and PDF formats, with fast turnaround times and clear, fixed-price quotes. We also offer 3D laser scanning and Revit / BIM models for complex sites and buildings. Whether you're a homeowner planning a self-build or a developer preparing a major scheme, we help you make confident decisions from day one.

NJC Surveys provides accurate measured building surveys across the UK, using the latest 3D laser scanning technology to capture existing buildings in precise detail. We produce floor plans, elevations, sections and roof plans, as well as 3D point cloud data and Revit / BIM models for architects, engineers, designers and contractors. Whether you're planning a renovation, refurbishment, loft conversion, extension or change of use, our surveys give you reliable "as built" drawings to work from. We survey homes, listed buildings, offices, shops and commercial properties, capturing room sizes, wall thicknesses, ceiling heights, door and window positions, and structural features. Drawings are supplied in CAD (DWG), PDF and Revit formats, ready for planning applications, building regulations and lease plans.

NJC Surveys provides accurate PAS128 utility surveys across the UK, locating and mapping underground services before you dig, design or build. Using Ground Penetrating Radar (GPR) and electromagnetic location equipment (CAT and Genny), we trace gas, water, electricity, telecoms, fibre optic cables, drainage and sewer pipes, giving you a clear picture of what lies beneath your site. Every survey is carried out to PAS 128 standards, helping you avoid utility strikes, costly delays and redesigns, and stay compliant with health and safety requirements. Our underground service drawings are supplied in CAD (DWG) and PDF formats and can be combined with our topographical surveys for a complete site picture. Ideal for architects, engineers, contractors, developers and homeowners.

NJC Surveys have a team of setting out engineers and provides accurate setting out and dimensional control services across the UK, ensuring your building is constructed in exactly the right position, at the right level, and in line with the approved design drawings. At the start of each project, we establish precise control points, gridlines and site benchmarks, then set out foundations, building corners, piling positions, roads, drainage and boundaries. Using robotic total stations and GPS equipment, our engineers help contractors and builders avoid costly mistakes, rework and delays. We also provide as-built checks and level monitoring throughout construction to confirm everything is built to tolerance. From self-build homes and house extensions to housing developments and large commercial buildings, NJC Surveys has supported projects of every size.

NJC Surveys provides accurate structural and construction monitoring across the UK, tracking movement in buildings, structures and the ground around your site. Using high-precision total stations, levelling equipment and wireless monitoring sensors, we measure settlement, heave, tilt and deformation during excavations, demolition, basement construction, piling and other high-risk works. Our automated monitoring systems and desktop platforms provide real-time readings and instant alerts when trigger levels are reached, so problems can be spotted, analyses and dealt with before they become serious. We monitor neighbouring buildings, party walls, retaining walls, bridges, railways and crack movement, giving contractors, engineers and clients clear reports and peace of mind throughout the project.

NJC Surveys provides accurate volumetric surveys and 3D ground modelling across the UK, helping clients understand exactly how much material is on their site and what needs to be moved, removed or brought in. We create detailed 3D terrain models and digital ground models (DTMs) that clearly show contours, slopes, levels and changes in elevation, giving architects, engineers and contractors a clear picture of the land before work begins. By comparing existing ground levels with proposed designs, we calculate cut and fill volumes, earthworks, excavation quantities and spoil removal, helping you plan muck away, balance materials on site and avoid costly over-ordering. We also produce machine control models for GPS-guided excavators and dozers, compatible with Trimble, Leica and Topcon machine control systems, allowing groundworks contractors to dig and grade to the exact design levels with less setting out and less rework. In addition, we carry out drone stockpile surveys, quickly and safely measuring stockpile volumes for quarries, aggregates, landfill and recycling sites, supporting accurate project planning, cost estimates and stock control.

NJC Surveys provides accurate mobile mapping surveys across the UK, using vehicle-mounted laser scanners (LiDAR) and 360° cameras to capture survey-grade data while driving at normal road speeds. Since starting our first mobile mapping project in 2018, we have helped clients survey long stretches of roads, highways, streets and town centres quickly and safely, without the need for road closures, traffic management or surveyors working on live carriageways. The result is a highly detailed 3D point cloud and imagery that captures kerbs, road markings, signs, street furniture, drainage covers, bridges and building frontages. From this data, we produce topographical drawings, road condition surveys and asset registers.
