Our employees managed all heavy lifting works in-house. These were planned by an appointed person, overseen by a lifting supervisor and executed by slingers/signallers. A factor of safety (100%) was incorporated into every COMAH lift, and jib/slew restrictions were applied over sensitive assets such as 30 bar gas mains, volatile organic lines, acid lines, 11kv electrical services, instrument air and nitrogen services.
Numerous existing services, groundwater sampling points, interceptors, ejectors, drains, structures, buildings, pipe bridges, plant, equipment, roads and footpaths had to be retained and protected inside the heavy dismantling works site boundary. Our in-house structural engineering consultants, Swanton Consulting, provided the requisite temporary works design and calculations.
Dismantling works had to be designed and executed sympathetically to ensure existing drains and sumps were not disturbed as they were critical to process operations on-site.
All hot works had to be carefully controlled under our Hot Works Policy.
We used specialist jetting equipment for secondary cleaning of residual chemicals. Treatment and testing of pH and suspended solids were carried out prior to discharge.
We have work collaboratively with Inovyn to place great importance of the “designing out” and managing of risks associated with health, safety and environmental matters as well as maximising environmental protection.
We have employed several local people from the Runcorn area and provided the necessary training to them to give them an opportunity to work in the demolition industry. These staff have been outstanding in their application and enthusiasm for the industry and have progressed into positions within the company on Runcorn projects, with some travelling to other major projects within the group.
We have completed the removal of redundant assets in the Weston Point Power Station Pump House, the demolition of the Waste Brine Treatment Plant and the Weaver Stock Sheds and the decontamination and removal of Mercury Cells from J Units.
We will soon be commencing demolition, decontamination, and remedial works at the Liquid Chlorine Plant.
