Total Solutions in 'Controlled Hydraulic Movement'
 
Bridges
We have broad experience with the controlled hydraulic movement of road, rail and waterway bridges. During these projects we work closely with the appropriate local authorities, national bodies, contractors and civil engineers. Our aim is to provide professional services that cause minimum disruption and maximum safety. An overview of some of our projects is outlined below.
Our techniques include:
Lifting Sliding Bearing Replacement Propping Stressing/Tensioning Strand Jacking Weighing
 
All the work for this extensive stressing project was carried out inside the box girders of the bridge, with little or no outward sign of the major strengthening work going on inside. Huge steel tubes were permanently installed and pre-stressed to relieve stresses in the support structure and thereby increase the load carrying capacity of the bridge. Our part of the project involved the installation and management of a computer controlled 48 jack system to apply loads of up to 1000 tonnes to the ends of the tubes prior to them being wedged and welded in place.

Wellington Suspension Bridge - Aberdeen
 
This listed structure spanning the River Dee, has been undergoing a major overhaul. First built in 1830 to replace the Craiglug Ferry, the bridge was closed to vehicular traffic in 1984. In 2002 it was assessed to be unsafe for pedestrians and a campaign was started to restore the bridge. Our work has involved helping with the replacement of critical link pins at both ends of the bridge. Single strand jacks fitted to special support frames have been used to remove the load on the pins so that engineers could replace them.
