Minnesota Power Boswell Energy Center Dry Ash Fill Area Maintenance Building

Project Type: Maintenance Building Boswell Energy Center; Cohasset, MN

Client: Minnesota Power

LHB’s Industrial Group was hired by Minnesota Power to design a 94-foot by 60-foot by 22-foot-tall maintenance building for their ash fill area trucks, dozer and water tanker at the Boswell Energy Center. The scope of work included designing the building and supplying bid specifications to enable the building to be constructed in 2008. The building consists of three vehicle bays, two of which are drive through, an internal office, lunch room, and bathroom area. One vehicle bay includes a one-half-inch think layer of BASF’s Mastertop® Anvil-top 300 due to the tracked vehicles being driven or housed within the building. A thickened edge, floating concrete slab foundation was selected due to the land fill clay liner breaching restriction and bears on the dry ash material contained in the fill area. The building structure itself consists of precast concrete, double tee walls and roof plank members. Precast concrete was selected based on preliminary estimates versus a steel frame option and the possibility of corrosion at the project location.
