also travel via the A70 south-west of the site. All construction HGVs, construction light
delivery vehicles and vans and construction staff have been assigned with 50% along the
A70 north-east of the site and 50% along the A70 south-west of the site.
7.5.10 As set out above, a preliminary design access junction has been designed and is shown at
Appendix 7.1, which has taken due consideration of the existing road geometries, the
adjacent road boundaries and the swept path of the abnormal loads within the extent of
surfaced road without any reliance upon verge use.
Construction Traffic Trip Generation
7.5.11 The construction of the six turbines is predicted to be over a six month programme and is
summarised in Chapter 4: Description of the Proposed Development.
7.5.12 The likely traffic generation resulting from the process can be split into the following
elements:
• Low loaders containing wind turbine components;
• HGVs to deliver and remove necessary equipment and materials to and from the
proposed wind farm; and
• Cars/vans containing members of the construction workforce.
7.5.13 The estimated traffic generated during the construction phase for each of these elements is
attached at Appendix 7.3 and summarised below.
Abnormal Load Trip Generation
7.5.14 An abnormal load movement is defined by Transport Scotland as a vehicle in excess of
18.3m in length or 2.9m in width or 44 tonnes in weight. The hubs, nacelles, blades and
foundation plates will be placed on articulated vehicles which exceed these dimensions
7.5.15 The vehicles used to transport turbine components would constitute abnormal loads only on
the delivery phase of the journey since the extendible trailers are retracted to the size of a
standard articulated vehicle (16.5m) during the return leg. Each delivery of turbine
components therefore consists of one abnormal load movement on the inbound journey to
the proposed wind farm and one HGV movement on the return journey.
7.5.16 Turbine deliveries are predicted to take place during the third, fourth and fifth months of the
six month construction process. During that period up to 78 abnormal loads of wind turbine
components would be delivered to the proposed wind farm, including blades, tower sections,
transformers, nacelles and cranes and components for the six turbines.
7.5.17 Based on the construction programme this equates to a maximum of 26 abnormal load
deliveries per month.
Heavy Goods Vehicle Trip Generation
7.5.18 It is estimated that 960 construction HGVs will access the proposed wind farm over the six
month construction period (1,920 two-way HGV movements). This number of HGV
movements is partly due to aggregate being sourced off-site and being transported to the
site. It is noted that the abnormal loads contract to a typical HGV size when departing the
site. With the inclusion of these, the total number of construction HGVs (non abnormal loads)
over the six month construction period equates to 1,998 two-way HGV movements. The
