The Aggregate Industries team was tasked with providing 480m3 of ready-mixed concrete needed for each of 22 turbines bases. However, this was no simple feat due to prohibited direct access to the site using the nearby A71, which added a further 10 miles to the journey from the supplying plant Duntilland. Nonetheless, the Aggregate Industries logistics team was able to overcome these road restrictions to meet the project needs.

The specification of concrete was equally challenging. After careful consideration and extensive trials, the Aggregate Industries Technical team designed a bespoke concrete mix incorporating BASF’s MasterGlenium 126 admixture. Adding further pressures, Aggregate Industries was granted access to the site in December 2015, with an extremely tight programme, which called for turbines to be erected by August 2016 ready for the energisation date of September 2016.

The team came up with a plan for 12 truckmixers and two plants to complete the turbine base pours in an allocated 12 hour window, whereby, for the bulk of the contract, one to two turbine bases were poured per week.
