  North Bethesda Conference Center Pedestrian Bridge




Keller provided Construction Management at Risk Services to the Maryland Stadium Authority on the North Bethesda Conference Center Pedestrian Bridge project. This project consisted of the construction of a curvilinear, enclosed, climate-controlled pedestrian bridge linking the existing North Bethesda Conference Center to the Center’s new prestressed, precast concrete parking structure.  This project involved a sloped walkway connecting Garage Level 3 to Conference Center Level 2 which required selective demolition and renovations at tie-ins to both existing buildings.  The exterior curtainwall has a compound curved geometry as it is both canted outward and curved.  The bridge is structurally supported by a new, V-column and foundation at the Conference Center and a slide bearing connection on a reinforced concrete corbel at the Garage.  The bridge design includes a full height streel truss with horizontal and diagonal bracing.  The existing building constraints required an extremely high level of quality control and precision execution.
