LDT staff are also authorised to carry out aerial surveys by the Civil Aviation Authority and are licensed to operate remote-controlled aircraft for this purpose.

With a strong commitment to customer satisfaction and a dedicated, professional manner, LDT has been delighted to work with some of the biggest names in the electricity industry on a repeated basis.

One such project presented a range of unique challenges due to the topography of the region in question. Scottish Power required a 7.5km, 33kV overhead power line route to be set out through a section of particularly rugged terrain that had been classified as an Area of Outstanding Natural Beauty (AONB).

Despite the obvious trials involved in completing such a project, construction began right on schedule, with pole and stay positions that were accurate and clearly marked.

Scottish Power was then presented with as-built records to assist with ongoing asset management. LDT has now enjoyed working with Scottish Power on a diverse range of projects, including topographical surveys of existing line routes, in addition to overhead line survey and redesigns.
