Simplifying the supply chain during complex bridge repairs
When the concrete piers for a bridge supporting a busy motorway undergo repair, the implications can be far-reaching, with the potential for road closures, delays and diversions.
The ability to simplify the supply chain on complex projects by having an expert not only carry out the design, fabrication, and delivery of the temporary works, but also the installation and removal, can be what makes all the difference for the successful delivery of some civil infrastructure projects.
That’s why one customer turned to Mabey Hire when the concrete piers for a bridge supporting a busy motorway needed to undergo repair. With the potential for road closures, delays and diversions, the project needed a comprehensive plan that could be managed efficiently and effectively to avoid public disruption.Back to top
The M60 Palatine Road Viaduct carries the M60 over the B5167 Palatine Road and the River Mersey in the Northenden area of Manchester. Constructed in 1974, the bridge comprises three lanes and a hard shoulder on each carriageway.
A routine inspection concluded that a number of the concrete pier crossheads on which the bridge sits were under strength and should be repaired and strengthened. Repairs to the drainage systems also needed to be carried out.
Located on one of the major routes near Manchester Airport and Trafford Shopping Centre, closing the Palatine Road Viaduct, even in just one direction, would cause major delays and inconvenience for M60 road users. Over 175,000 vehicles use M60 junction 5/6 every day.Back to top
Balfour Beatty Mott MacDonald JV approached Mabey Hire to design, fabricate and install a solution to prop the structure, and monitor it for movement so that repair works could be carried out to each of the piers safely and efficiently, while the bridge remained open.
Using Mabey Hire's Superprop a high-load shoring system with integrated adjustment and hydraulic pre-load and lifting facility, along with hydraulic jacks and bespoke bearings, Mabey Hire designed a bespoke proprietary propping system and installed it in June 2018.
The project required design and fabrication of custom parts. On all of the piers, bespoke steel base collars were designed and installed, to transfer horizontal forces into the piers.
With the road remaining open, Mabey Hire’s live monitoring solution continuously measured vertical, longitudinal and transversal movement. This provided assurance that set parameters were not exceeded, ensuring the safety of the road users and operatives working on the bridge.
Mabey Hire’s equipment remained on site until March 2019. It has so far completed first two out of 15 piers it will work on.

Mabey Hire presented a total solutions package which saved us the inconvenience of engaging numerous sub-contractors for the propping works. Had Mabey Hire not stepped in with such a comprehensive plan for the propping and monitoring, the alternative would certainly have been a more expensive option requiring temporary foundations. Furthermore, the ability to monitor the structure in real time enabled the M60 to remain open while the work was carried out, which was a huge advantage for the travelling public
