Mechanical Engineering, bridge bearings, structural engineering Specialists In Structural Movement Control

Ekspan were appointed by Tamar Bridge and Torpoint Ferry JC to remove the existing joints and install like for like new FIP expansion joints complete with components and fixings.

The joint installations would affect the operational status of the Tamar Bridge, therefore it was vital these works were efficiently planned in terms of programme time, materials, procedures and traffic management. Hence for this reason, a “trial run” operation was undertaken (in May 2015) 2 weeks in advance to the full installation works. This involved removing an existing FIP expansion joint plank at the center of the bridge, consisting of 3 sections (1 bridging plate and 2 bellows) whilst also inspecting and evaluating procedural issues that arose and conditions of the existing grout steelworks. All procedures and times were recorded during the removal of these units and additional prep work and testing was undertaken off site - this ensured the methodology for the major works planned for July 2015 was workable within the client’s programme constraints.

The successful installation of the FIP expansion joints at Saltash main tower and Plymouth main tower (July 2015), attributable to meticulous pre-planning, involved 2 teams of Ekspan operatives working continuous throughout including nightshifts on 2 consecutive weekends during a complete 3 lane closure.
