Jones Bros engineers and operatives have considerable expertise in developing infrastructure for wind farms but after discovering two geological faults on a recent project they were faced with a major challenge.
The two faults were uncovered after the team began excavating earth for foundations at SSE’s 173MW Clyde 2 54-turbine wind farm in Scotland.
Two huge foundations needed to be constructed – each one measuring 24 metres in diameter – the length of four badminton courts and five metres deep.
Constructing each huge base involved:
- 50-60 workers
- 27 mixer trucks
- 24-mile round trip from batching plant to turbine base and back – all on tracks built on site
- 800m3 of concrete – usual bases take 600m3 of concrete
- 20 tonnes of additional steel
- 336,000kg of cement
- 576,000kg of sand
- 853,600kg aggregate
- 124,000ltrs water
- 3,024lts of admixture
