Environmental and Energy Experience

Environmental and Professional Services for the Formerly Used Defense Sites (FUDS), Program for sites located within the Golden Gate National Recreation Area (GGNRA)



Industrial Maintenance Services, Inc. (IMS) assembled a team to support the U.S. Army Corps of Engineers in reaching goals for the Formerly Used Defense Sites program while minimizing project life cycle costs.

The project consisted of the coordination and conduction of site Inspections, Remedial Investigations, including Feasibility Studies and Remedial Actions/Removal Actions at various sites located within the boundaries of the Golden Gate National Recreation Area near Sausalito, CA.  All efforts will need to be coordinated with the current landowner, the Unites States Department of the Interior, National Park Service and various stakeholders including regulatory agencies.  IMS team is also providing environmental advisory services for environmental restoration activities at the GGNRA under the purview of the Sacramento  District of the Unites States Army Corps of Engineers.  These tasks include interfacing with the NPS, and various stakeholders including regulatory agencies.

Taconite Ridge Wind Farm – Minnesota Power & Light – Mt. Iron, MN



IMS workforces received and unloaded approximately 120 truckloads of equipment to construct (10) 2.5 MW Clipper Wind Turbines. A Liebherr LR 1400 was used as the main erection crane to hoist the tower sections and turbine components. Smaller auxiliary hydraulic cranes were used to support the erection process. Each tower consisted of (4) bolted sections to achieve a rotor height of 80 meters (260 feet). The rotor diameter is 96 meters (315 feet) and weighs 70 tons, which is rigged and installed as a single unit. Each fastener was tightened to a specific value in a specific pattern, most requiring the use of hydraulic powered torque wrenches. IMS crews worked a schedule that maximized assembly production during low wind conditions to complete the erection of the (10) turbines in 6 months.
