Swing clearance survey
We measure sag and swing at maximum temperature and show the statutory clearances so you can meet ESQCR.
Survey & Design Expertise to Move Your Project Forward
Overhead power lines are what we specialise in. We survey them and we design them, and we're not limited to that — topographic surveys, underground utilities, setting out and other site work sit alongside it. We're authorised by the CAA to fly drones, so we can survey from the air when that's the better way to do the job. Since 2010 that work has added up to a long run of successful projects. We're a small team, so you talk to the people who will actually be on site. Tell us what the job needs and we'll work out the right survey and design for it.
Our Specialist Survey Services
Aerial drone survey
CAA-authorised drone surveys for mapping and inspection, with models ready when the air is the safer way to work.
3D laser scanning
Accurate scans of lines, structures, and sites, delivered as point clouds you can measure and check for clashes.
Overhead line survey
Route plans, profiles, and schedules for UK overhead lines, on the Ordnance Survey grid so every drawing matches.
Supporting Survey and Design Services
Topographic survey
Site surveys for power line and development schemes, with maps, contours, and a terrain model your planners and designers can build on.
Setting out services
We transfer the design onto site and mark foundations, supports, and structures so construction starts in the right place.
Underground utility tracing
We locate and mark buried utilities before excavation, and report what was found so you can dig with fewer strikes and less delay.
