Construction—North America—USA—Structural Repair Solutions DSI demonstrates its technical Competence during Repair Work on the Talmadge Bridge The Talmadge Memorial Bridge is a four lane, cable stayed bridge in the state of Georgia, USA carrying US route 17 through Downtown Savannah across the Savannah River to Hutchinson Island. There are two pairs of H-shaped pylons supporting the stay cables. The main span of the bridge that was completed in 1991 is 335m (1,100ft) long, and the overall bridge length is 3.1km (1.9mi). In the summer of 2015, DSI was contracted by the General Contractor, The Industrial Company (TIC), to perform important component repairs to the Talmadge Memorial Bridge. As with all bridges, periodic repair and maintenance is needed to keep the structure in good condition, and this was the second time DSI’s expertise was called upon for the repair work. DSI had already supplied and installed 142 288 retrofit dampeners on the Talmadge Bridge cables between 2006 and 2008. The scope of DSI’s second contract was to replace all the stay cable boot seals at the pylons and underneath the bridge deck. Furthermore, DSI renewed the cable stay pipe tape where the existing tape had sustained damage. The contract also included the inspection and repair of all the anchorage caps on the stay cables – both at the lower anchor locations below the bridge deck and at the upper anchor locations in the pylons. The anchor cap repairs included installing new seals, packing the caps with new corrosion inhibiting compound and replacing anchor bolts as required.
