Sunoco Logistics planned a massive $2 Billion project to install an approximately 180-mile petroleum pipeline from Tiffin, Ohio to Pittsburg, Pennsylvania through open cut and horizontal directional drilling methods across terrain that ranged from agricultural flat lands to mountainous.
Permitting for the crossing roads, highways, railroads, wetlands, certain private properties, and steep terrain required an extensive geotechnical investigation consisting of several hundred borings and rock cores extending to depths up to 250 feet. To further complicate the investigation, Wolverine had an extremely tight deadline of a month and a half from authorization to report delivery in freezing winter conditions. The schedule required the use of up to 8 ATV and Truck-mounted drill rigs and several other field personnel hauling water, supplies, and traffic control. Wolverine completed the project on time and under budget.
