AOC 15 user manual Site Access, Foundation Installation

5.0 Site Preparation 32

WARNING

DURING THE INSTALLATION OF A WIND TURBINE, THE SITE SHOULD BE MAINTAINED SO THAT IT DOES NOT PRESENT A SAFETY RISK/HAZARD TO PERSONNEL.

The following sections discuss some of the siting factors, which must be considered before the wind turbine arrives.

5.1Site Access

Access to the site is a prime consideration when installing a wind turbine. Limitations in site access will determine the type of installation and equipment that can be used. Potentially limiting factors include:

∙Roadways (existence, permits, size, surface, restricted use, weight bearings)

∙Bridges (size, load capacity, width and height clearances)

∙Physical clearances (overhead wires, lamp posts, turning radii, grade)

∙Traffic (movement to and at the site)

∙Lay down area (space to assemble the tower and locate components prior to installation)

5.2Foundation Installation

Foundation types and installation approaches are site specific and the foundations must be designed for the load conditions expected at the site in question. Refer to IEC Standards for Wind Turbines for additional information. Since AOC offers a standard and tilt-up tower, it should be noted that the chosen configuration will affect the position of the anchor bolts. For planning purposes regarding the tilt-up towers, it should be remembered that AOC only supplies the hinges not the erection equipment.

See Appendix F for foundation loads and details. The civil engineer responsible for the foundation design should consider site specific conditions.

Each tower leg should be grounded as per EIA standards. Rohn recommends using three 5/8” galvanized ground rods, 8 feet long and mechanically connected to each leg using #4 gage wire.
