The Dutch firm, which was acquired by Sweden’s Sweco earlier this year, has been commissioned by Banks Renewables to oversee pre-construction work at both Middle Muir and Kype Muir wind farms. It will provide data analysis to provide information for the civil engineers to be able to plan the installation of the wind turbines and electricity sub-stations.
Grontmij’s Glasgow office will interpret data gathered by Hamilton-based Raeburn Drilling & Geotechnical.
The combined construction costs of both sites are expected to reach £150m.
Grontmij senior renewables engineer Kathryn Sanders said: “Grontmij have supported Banks with our geotechnical and civil engineering expertise on many wind farm projects. It continues to be great to work alongside them from the start, particularly as they pay attention during the development of their projects and are willing to adapt to accommodate local concerns.”
Kype Muir Wind Farm, south of Strathaven, is a 26-turbine 104MW wind farm and was approved in May 2014. Middle Muir Wind Farm, north of Crawfordjohn, is a 15-turbine 51MW project that is set to deliver the tallest onshore turbines on mainland UK. It was approced in September 2014.
Banks development director Colin Anderson said: “These projects have taken years of careful planning and consideration – so it is a major milestone to see them reach this stage in the journey. Despite not being able to award this particular contract to a small local firm, Grontmij have been very understanding of our commitments and as a result have ensured that local firms are subcontracted wherever possible, maximising the benefit to the region.”
