Total Bridge Services and the Box Girder Strengthening Project
Since July 2008 Total Bridge Services has been involved with the New Zealand Transport Agency on a project to carry out significant strengthening of the box girders which carry the East (Southbound) and West (Northbound) outer lanes of the Auckland Harbour Bridge. Most Aucklanders will be familiar with these structures commonly being referred to as the Nippon Clip-on’s.
The people engaged on the job included structural and mechanical engineers, fitters, welders, painters, labourers, consultants/technicians (i.e electronic weld testing) the servicing crews, and general subcontractors. At its peak, the project never slept, with a workforce of close to 200 people working over three shifts and running up to seven days a week. This does not include many others working offsite in design and fabrication work to ensure that the installation work has been able to flow smoothly. The strengthening work is now in its completion phase with all the new strengthening components successfully installed. There is however, a period of repainting to do on both the exterior and interior walls of the box girders.
