Nature of Work: Enabling Works & Civils
Client: G2 Energy
Project Location: Hill House Farm, Bridgend
Summary
G2 Energy were contracted by their client, a wind farm developer, to provide EPC services on a 500kW single wind turbine project in South Wales. The project involved upgrading existing access, installing new access, foundation works, substation construction and new HV cabling to the point of connection.
G2 approached Darlow Lloyd & Sons to carry out enabling works comprising the construction of the access road and crane pad which Darlow Lloyd & Sons carried out using soil stabilisation along with rehabilitation of an existing section of track using specialist in situ crushing machinery.
The subgrade material along the route of the new road and crane pad was stabilised using an ultra low carbon binder from Cenin Cement and a layer of Type 1 was pushed out to act as the running surface. This Type 1 layer was then mixed with cement to provide the strength characteristics required by the cranes during the turbine erection works.
Darlow Lloyd and Sons also carried out the cable trenching & foundation works for the turbine and substation, through close partnership with sister company Darlow Lloyd Construction. In addition to these works, G2 also awarded Darlow Lloyd & Sons the contract to carry out earth trench works and landscaping and reinstatement of the site following completion of the turbine.
Benefits
Using soil stabilisation on this project enabled G2 to re-engineer the existing material on site to provide an enhanced strength to the road and crane pad through stabilisation. This meant that the amount of aggregate required to be brought in to site was significantly reduced, along with all associated vehicle movements.
Through the use of Darlow Lloyd & Sons as single point of contact, G2 were able to reduce their sub contractor interfaces and limit the exposure to project risk by using the significant plant and labour resource and experience of the Darlow Lloyd Group to ensure that the full civils & reinstatement package was carried out on time and on budget.
