Alternate Energy Systems
Johansson Engineering Ltd can provide the design and engineering services required the meet the CSA standards for these structures. Wind turbines and their associated foundation systems are classified as utility towers and are; therefore, explicitly exempt from the requirements of the Alberta Building Code (ABC).
A wind turbine that has an observation deck as a tourist attraction or as a working platform (observation deck) area such as for forest rangers are supporting an occupancy and would be required to fulfill the requirements of the ABC. If the working deck was used solely for the purpose of performing maintenance on the wind turbine then the wind turbine would still be classified as a utility tower.
