California Ave. Bridge Clearance Improvement (CDOT)
Techknow designed an Earth Retaining system for lowering a viaduct at California Ave. between Taylor and Fillmore Streets under the CSX Railroad bridge. In the absence of structural design drawings, Techknow performed site inspections to plan the sequence of operations to increase the vertical clearance under this 43’ wide bridge. To achieve this, Techknow recommended lowering the existing sewer invert elevation by 6”; replacing a 42” diameter sewer with two 30” diameter sewers; replacing a 24” diameter water with a 16” diameter water line; and installing Cantilever sheet piling on both sides of the existing sewer to eliminate the risk of undermining. Prior to sewer removal, alternate sewer arrangements were made. Since previous design loads were not available, Techknow performed new calculations to estimate the column loads (including impact loads). Due to the rusty and deteriorated condition of the columns, construction was performed at night, to minimize the live load from moving rails and eliminate the need for Bridge shoring. During the excavation stage, prior to backfilling, plates between channel columns also needed to be jacked. Techknow followed AREMA, CDOT and CSX standards and manuals for design and load calculations.
