Overhead line survey and design Overhead line (OHL) surveys are the bread and butter of services we offer at UTSS. These types of surveys allow us to provide vital data, allowing us to create accurate design models of solutions for a range of services including cable avoidance, utilities and vegetation management.
How Does It Work?
We firstly identify all line routes and potential hazards on site. Using a GPS and theodolite we record all ground and vertical features including slope distance, zenith angle and the horizontal distance of the slope. The resulting figures allow us to produce a ground and line design map.
Why Is It Useful?
Our surveys and OHL design maps allow businesses to provide on site intelligence to network operators for solutions that impact investments, the environment and underground utilities.

Case Study – Catesby Estates Issue
Catesby Estates were looking for a solution to enable two spans of 132kv overhead line on towers to be removed – this was with a view to them seeking opportunities for housing development. In this instance we were working for the land promoter and not the distribution network operator (DNO) so had no right of entry to obtain the survey data.
Our Approach
For us to view the overhead powerline without entering the landowner’s property we used a 3D scanner mounted on a 15m pneumatic pole, giving us an aerial view of the gardens. For the areas that were accessible we undertook some standard tripod-based scans. We did look at alternative methods of execution such as: • • •
helicopter LiDAR solution fixed wing LiDAR solution 3D laser scan - good solution but wouldn’t capture the data within the fenced garden areas
Our approach allowed us to bridge the gap between practicality and affordability for the client whilst also demonstrating the variety of approaches to an OHL survey. For more information on Overhead line surveys and how it could help you please contact us.
