Jubb provided civil engineering design services in support of the development of an 18 megawatt wind energy scheme based around 9 turbines in a rural part of Devon.

Drawing on the team’s experience across a wide range of renewable energy, including development of many wind energy schemes, Jubb were able to understand the client’s drivers and the nuances of delivering abnormal loads, as part of which manufacturer’s deliver critical components ‘straight off the ship’ at specific dates that cannot be missed.

A series of outline highway improvements were developed based on the planning stage design and our past experience of the delivery of turbines, which allowed us to identify and advise on additional works required that had not previously been anticipated. As well as a series of minor alignment improvements, the A3124 was diverted 200m to the west forming a new junction with the A382 in Whiddon Down. The existing junction was an accident black spot and, as well as facilitating the delivery of turbines, the scheme provided much needed safety improvements, normalising turning manoeuvres along a busy HGV route with poor visibility and having frequent turns of the acute angle by articulated vehicles.

Jubb provided civil and geotechnical design throughout the project, including utility diversions. A robust set of specification documents were produced to allow the client to go out to the market and achieve technical approval from the Highway Authority. Jubb were also employed through the construction stage to provide design support as required and developed a number of documents, including an earthworks strategy, in order to discharge planning conditions.

The works were proven through a dry run with delivery vehicles allowing delivery of the turbines on time and to programme.
