Beauly to Denny Power Line

time critical technical support was essential for the success of this project

ByrneLooby designed the foundations for the transmission towers used along the 220km Beauly to Denny Power line in Scotland.

The transformational 400Kv transmission line traverses a variety of geologically challenging areas including Psammite, Schist and weaker sandstones across the Scottish Highlands and has been referred to as the most significant grid infrastructure project in a generation.

As geotechnical designers, we developed a number of alternative piling solutions for the transmission towers before optimizing each individual design for the ground conditions encountered at each location resulting in significant time and material savings for our client. The efficiency of our designs was borne out through the competitive tendering process which resulted in the award for our client of further sections of towers along the route.

We also provided time critical technical support for our client during the entire construction phase.    

  Scope of project

  • Pile design for the steel lattice transmission towers constructed along the 220KM Beauly to Denny Power Line.
  • Designed a number of alternative piling solutions to accommodate the diverse ground conditions before tailoring the solution for each individual tower. 
  • Typically, the foundation piles were 300mm diameter minipiles designed to accommodate a range of compression tension and sheer loads.
