In order to achieve the target of reducing the UK’s carbon emissions by at least 80%* by 2050, as set out by the 2008 Climate Change Act, the country has seen heavy investment in a variety of renewable projects. Batsworthy Cross Wind Farm, near Knowstone, Devon, is one such project, with construction of nine new wind turbines underway and in line for completion in summer 2016.
We Aren't All Hot Air
The pours were selected to take place every Thursday in order to avoid the tail backs that can build up on the A361 on busy holiday change-over days through the North Devon summer season.
Approximately 300m3 of concrete is required per foundation, with each constructed in two pours; an initial pour to form the larger ‘base’ section and a second much smaller pour to form the ‘collar’ (this includes the cast-in element to which the tower connects).
As a result, approximately 28 concrete deliveries are required to site, spread throughout the day, to fulfil each ‘base’ pour. Hopkins utilises two concrete boom pumps, 36m and 39m, and four artic mixers on each of the pours, with the team completing one base pour every week. Paul says: “I was initially concerned about fulfillment, as Hopkins is based in Somerset, but after a few conversations my worries were settled and we have never looked back!”
From start to finish Hopkins will supply in excess of 2,200m3 of concrete to hold the nine turbines in place. The turbines are estimated to generate enough energy to supply roughly 8,900 UK households, of average size, per year.
Paul states: “Not only was Hopkins able to keep up with our demands, but the quality was always consistent. The high standard set by their management filtered down through the whole of the company, as every employee who visited our site was completely professional and helpful. I have no problems recommending them to anyone else and Hopkins will be my preferred supplier for any future job I have in the region.
