BNSF Corwith Yard Cantilever Crane Expansion
Hanson provided design engineering and construction management services for the cantilevered rubber tire gantry (CRTG) crane expansion at BNSF Railway Co.’s Corwith Intermodal Facility in Chicago.
The project’s design encompassed the westward expansion of two additional tracks and one relocated track to allow the use of wider-span CRTG cranes. Design elements included conceptual layouts, support track reconfiguration, pavement thickness calculations, drainage modifications, new high-mast light poles and new compressed-air tanks and lines. The layout accommodated the use of traditional rubber-tired gantry (RTG) cranes for an alternate operation along the same track expansion.
Construction management tasks included observation for asphalt paving along the strip tracks; 20-inch-to-25-inch, cast-in-place concrete paving for crane runways; storm sewer and track underdrain installation; foundation pouring for electrical and mechanical infrastructure, high-mast light pole erection, electric conduit and panel box installations; compressed-air tank and air line installations; trailer parking and crane runway striping; and the 4-foot raise of an asphalt-paved, 9-acre trailer parking lot. One 3,200-foot track also was paved with asphalt so it could accommodate train and truck traffic for CRTG and RTG crane operations.
