Afton Windfarm

Ayrshire, Scotland

The schemes is a 27 Turbine windfarm with a 50MW capacity and is situated near the village of New Cumnock, East Ayrshire. Tony Gee was the lead designer for Farrans Construction.

A major element of the pre-construction works related to Scottish Water approval for the public road improvement works along Afton Road. Under the road are 400mm and 450mm dia water mains. The mains provide drinking water to a significant area of the Ayrshire population. The public road works therefore had to go through the Scottish Water DOMS (Distribution Operation & Maintenance Strategy) approval process.

Tony Gee produced a schedule of conflicts that identified all conflicts between the existing water mains and the new passing places/road widening. Some widening and passing places were then re-positioned to avoid the mains and thus eliminate the conflict; however the exact location of the mains in relation to the road was largely unknown. We therefore commissioned a Ground Penetrating Radar survey to confirm the exact pipe locations which enabled a further number of conflicts to be eliminated or reduced. The risk associated with the remaining conflicts was determined through a Ground Movement Impact Assessment Report by Jacobs, and thus a pipe protection plate proposal we designed, was proposed for the sections of pipe which were deemed still at risk, subsequently approved by Scottish Water and the Ayrshire Roads Authority.

Through working as part of a team the requirements of the DOMS procedures were met and approvals were achieved with no undue delay.
