Since January 2024, Mackley has been undertaking repair works on several bridges along the Lower Mole. The final stages are now nearing completion, with the assets soon to be handed back to the Environment Agency.
Mackley worked from North to South on the River Ember working on each of the 7 assets. Island Barn Bridge & Walkway, Molember Boat Rollers, Royal Mills Staff Access Bridge & Channel Confluence, Viaduct Bridge, Viaduct Weir Walkway, Imber Court Loop Bridge and Zenith Weir Footbridge.
Depending on the scale of each repair, as well as programme constraints, weather conditions, and tide times, some works were carried out concurrently using smaller satellite compounds, while others required more substantial, stand-alone operations. Environmental considerations for the project included FRAPS and EAP monitoring of water levels.
Works involved the design and build of expansion jointing, structural repairs, painting, resurfacing, waterproofing and repairs to embankments, parapets and concrete structures. Following an embankment slip over the Christmas period, additional embankment and apron repairs were carried out located by Island Barn Bridge, using rock bags. A gauge board was also installed to monitor water levels close to Royal Mills channel confluence. The design was in partnership with Tilt.
Alice Baker, Sub Agent said of the project “Working alongside such a committed and hardworking team was a privilege, and their collaboration was instrumental in bringing this project to a successful conclusion.”
There were initial challenges as Mackley was not the only contractor on site. Through proactive communication with the other site team, they were able to carefully plan and schedule their activities to avoid disrupting their operations. In consultation with the client, Mackley agreed to demobilise when their tasks were complete and return once the other contractor’s works were finished, allowing everyone to progress efficiently.
The client was particularly pleased with how effectively Mackley coordinated with local homeowners and landowners, as well as how well they collaborated with the other contractor on site.
This work was critical to ensuring the safety and longevity of the structures. Carrying out maintenance extended their lifespan, protected the surrounding area from flooding, and repaired damage caused by high water levels and flows.
