KS Associates provided bridge inspection services for the CUY-6-1456 Detroit Superior Bridge as part of ODOT District 12’s VAR-D12-Bridge Inspection project (Part I). As team leader, KS Associates provided an In-Depth Fracture-Critical Inspection of the bridge.
KS Associates utilized conventional access, climbing techniques, a man lift, and a bridge inspection vehicle to inspect all members of the 591-foot steel tied arch main span over the Cuyahoga River, within an arm’s length. The more than 1,600 feet of reinforced concrete arch approach spans were also inspected, as well as both east and west approach tunnels.
Work included sounding portions of the concrete structure that appeared to be unsound or deteriorated. KS Associates documented the changes in previously mounted crack monitors on the concrete portion of the structure.
Articulated arm lifts were used on the lower deck to inspect the main deck structural members, pinned joints, and concrete columns and arches. KS Associates utilized confined-space entry techniques to assess the condition of cells that compose the substructure, below the lower deck at the west side. KS Associates utilized a gas detector and emergency air for entry.
KS Associates compiled all photos, field notes, and measurements to develop quantities and ratings for an element level field inspection report and entry into ODOT SMS.
KS Associates provided services as a subconsultant to Jones-Stuckey, a Division of Pennoni.
