Wind-power installation works

Description

Construction of infrastructure consisting of roads and hardstands for wind turbines at Nørrekær Enge. Nørrekær Enge is located south of Limfjorden and next to Næsborg and Kølby in the central part of Northern Jutland, Denmark. The proposed Nørrekær Enge wind farm development is a repowering project and the current site design consists of 36 new wind turbines. The site is an area of reasonably flat, open farmland. New roads along the existing farm land boundaries must be constructed, so the individual wind turbine locations can be accessed by construction equipment and the turbine components. The road layout is designed based on geotechnical survey and according to the requirement of the turbine supplier. For the erection and maintenance requirements at each wind turbine location a hardstand area in region of 1 500 m2 will be required. For the new roads and hardstands there must be relocated existing field drainage and installed new drainage. For 16 pcs. of the hardstands it is necessary to carry out pile foundation for the main crane. There are expected 4 groups with 5 piles in each group to be expected 5 units. piles per hardness. On top of each pile group must be cast a reinforced concrete slab for the crane support legs. The current layout includes ditch crossings, which will require piping that allows water to flow beneath the road. According to enclosed preliminary contract time construction on site is expected to start first quarter 2020 and end fourth quarter 2020. The work is offered in a total main contract. The following work shall be carried out: — excavation of mold, — excavation for new roads and hardstands, — construction of drainage for roads and hardstands, — construction of roads and hardstands as gravel roads, these must be carried out with geo-reinforcement mesh, — construction of asphalt on transition to public road, — maintain of the roads in the installation period of the turbines, — reestablish of selected areas back to farmland.
