VolkerStevin successfully completes Lower Mole project
VolkerStevin recently completed works at the Lower Mole project, on the River Ember, Southwest London. The project, delivered on behalf of the Environment Agency (EA), was contracted to refurbish damaged and aging flood structures that protect approximately 3,000 homes from flood risk and improve eel passes in line with updated regulations.
A total of 12 flood gates were refurbished across three different flood control structures. In addition, the team replaced the tilting gate drive bridges on all three structures and installed two new control panels. The radial gate ropes, used to raise and lower the flood gates, had exceed their lifespan and were therefore replaced. Enhanced security fencing was installed and electrical improvements were made by replacing the wiring and containment on all structures.
Multiple lifting operations were conducted to install stoplogs, dismantle the old gate drive equipment and bridge, and install the new bridge. Additionally, diving operations supported the stoplog installation and the replacement of wire ropes.
Upgrades to the eel passes was also completed, these upgrades will allow the successful migration of eels in the River Ember to continue.
The sites were located within residential and public areas where careful planning of our works enabled high risk activities to be carried out safely and with minimal impact.
Upon completion of the project, the team has prolonged the lifespan and improved the usability of the structures, which can now continue to protect surrounding homes.
James Fuller, Environment Agency Senior Project Manager, said: "As the EA Project Manager, I would like to take a moment to highlight the great work carried out by VolkerStevin on the Lower Mole project.
