Our project is a scientific facility located on a greenfield site in northern Canada. A polar bear fence is essential for the protection of researchers from bear attacks and the facility from bear damage. This 8’ high bear fence is placed on 14” diameter x 5’ deep concrete piles spaced at 8’ over centre. The fence encloses the hardscape and buildings. Every effort to limit site disturbance involving the installation of the fence has been considered. Given the necessity of the fence and it’s robust construction could it be allowed a reasonable offset?
