Stronelairg Wind Farm
Fort Augustus, Scotland
Project synopsis
Ground investigation specification and supervision, substation platform earthworks design and substation drainage design
End client
SSE Renewables
Stronelairg Wind Farm is located 11km southeast of Fort Augustus. The substation platform is at an elevation of 675m (2275 ft) AOD with some turbines located above 750m. The wind farm scheme consists of 66 wind turbines and has a total generating capacity of 228MW.
Tony Gee undertook the detailed design of the substation platform earthworks including the detailed earthworks volumetric assessments, as well as acting as Technical Advisor for the project.
We modelled the borrow pit based on a fill volume of 35000m3 being required and optimised the location, profile and plan size of the borrow pit. A reinstatement profile of the borrow was developed with 2m of peat.
As Technical Advisor for the project, we supervised construction on the substation platform and the associated access track. The construction phase included:
- Inspection and acceptance of the sub-formation level
- Witnessing of onsite material processing, handling, placement and compaction
- Inspection and acceptance of formation level testing
Works were completed closely with the site team to ensure any issues were resolved in an efficient way. Construction began in late 2016 with the wind farm becoming operational in December 2018, six months ahead of schedule.
