The contract for the Ashmont Lagoon stipulated a 6 foot high fence, which is not a standard height. When G & J bid the job, they bid it on a five foot fence. Urban Systems is suggesting that if the County is OK with a 5 ft high fence, G & J can proceed on the basis that the County receive a credit for the reduced fence height, which should be roughly 30% credit on material.
Alberta Environment guidelines regarding lagoon fencing is as follows:
The wastewater lagoons shall be enclosed with a fence. The fence shall be designed and constructed to preclude the entrance of children nd to discourage trespassing.
