Installation of 3x110mmduct in trefoil and 1x Ø32 duct (for fibre optics) and warning tape over 30km. Depths installed at are 1.4m. Ground conditions were particularly hard in places with fractured rock and sections of deep peat. Duct installation was completed ahead of the civil contractor completing the access roads for the windfarm construction. Reducing sub-contractor interface, pinch points and overall programme of works.
Access to and from the point of work was made challenging with ground conditions and planning restraints of alternative access possibilities. However, ATP overcome these by using a helicopter to fly the duct from the compound laydown area to the work site and laid out at one hundred meter intervals. The use of ATV Hagglunds BV206 was used for operatives to get on and off site safely and in the event of an emergency whilst providing welfare facilities during inclement weather.
