Background to specification
Hall Construction Services was commissioned to construct a £16m wind farm for Banks Renewables, part of The Banks Group, beginning operations on the Armistead site to the east of the M6 in March 2012.
As well as making a significant contribution towards meeting Cumbria County Council’s renewable energy targets, the Armistead scheme would bring a range of other benefits to the local community.
It would also provide a boost for the Cumbrian economy through the local supply chain, with up to 20 people being employed on site at any given time during the construction process, and a number of local firms also working alongside Hall Construction Services.
But before the six wind turbines could be delivered to site in autumn 2012, a number of essential measures were required to prepare the site in a necessarily environmentally friendly way.
Extra careful steps had to be taken to construct the new wind farm, right down to the preservation of local water courses.
Amongst these was the crossing of a sensitive stream in order to transport materials on to site. This bridging work was done using culverts constructed from preformed sections of Tubosider bolted plate, from our range of profiles for all applications.
As main contractors, Hall Construction Services Ltd chose to maintain a successful partnership with Tubosider, this time using our bolted plate structures rather than our stormwater tanks and pipes.
Solution & benefits
As Ian Collier of Hall Construction Services explained, “The client required us to provide a cost effective efficient solution to cross the water course without disturbing the natural habitats. The Tubosider culvert proved to be the ideal choice.”
The wind farm will have an installed capacity of up to 12.3MW (estimated to meet the annual electricity consumption requirements of approaching 7000 homes) and connection to the local grid is expected to be finished before the end of the year.
The Armistead Wind Farm Liaison Committee, made up of local residents, elected representatives and the Banks Renewables team, also met regularly throughout the construction phase to ensure that it ran smoothly and that local people were fully aware of the progress being made.
