Hall Construction Services Limited were appointed by The Banks Group to undertake the design and build of a 6 turbine wind farm inclusive of plant works at Armistead Wind Farm.

The construction works entailed the enabling works for a 6 turbine wind farm with an output of 12.3MW, a switchgear/control building, an anemometry mast and associated civil and electrical infrastructure which comprised of stone access tracks, crane pads and concrete foundations.

The turbine generators are REPower MM82; 3 bladed horizontal axis with a maximum height to blade tip above existing ground level of 100m and approximately 60m to the centreline of the hub. The turbine transformer/switchgear units are housed externally to the turbine.

The electricity generated is transmitted to the wind farm switchgear/control building via 11KV underground cables to the electrical substation where it is fed into the local electricity network via the existing grid connection operated by NEDL.

Hall Construction Services Limited designed the access roads which consist of a 4.5km track to give access to each turbine individually. To reduce our carbon footprint we quarried all of the stone required for the construction process of these roads on site which came from the excavation of a borrow pit. There was no import of materials. ALL material was sourced on site, crushed and screened to required specification. The materials were laid and compacted to appropriate longitudinal gradients to enable access for the cranes and low loader vehicles.

Hall Construction Services Limited had to cross two water courses on the site therefore permanent road bridges were constructed. The water was inhabited by white clawed cray fish therefore Halls consulted with the appropriate bodies to ensure that the crayfish were not disturbed by the works.

To enable the wind turbine low loader vehicles to access the site the existing highway infrastructure to the surrounding area were altered to accommodate the vehicles as well as remaining traffic signs and street furniture.
