Joint Utility Trenching: By utilizing Joint Utility Trenching, a cost-effective pipeline installation method, the project benefited from shared costs with other utilities, resulting in significant savings. 2. Reduced Contingencies: The estimated contingencies, initially set aside for unforeseen circumstances, did not materialize, allowing for a reduction in actual construction costs. the comments below explain 20% favorable variance Enbridge Gas Inc.
