KDC, a market leader in decommissioning, demolition and land remediation, was contracted by SGN to decommission two historical gas holders at a site in Johnstone, Scotland.
The first gasholder was a below ground, spiral guided construction with four lifts of riveted steel, a brick and puddled clay tank and had been in operation for over 82 years.
The second gasholder, which was built in 1912, was an above ground spiral guided holder with two lifts of riveted steel and a steel tank.
Throughout the decommissioning process, KDC required a solution to help them maintain health and safety for their workers who were tasked with excavating the two gasholders of 8540m3 of water and 260m3 of sludge contained within the tanks, and then filling the holder voids with recycled, non-hazardous waste from the demolition process - approximately 6720 tonnes.
In addition, it was essential that KDC had site security in the form of a CCTV surveillance system that was able to help deter intruders and prevent any theft of their assets by proactively identifying any unauthorised personnel entering the site.
Finally, KDC wanted to produce a time lapse video of the decommission. The time lapse video would be used for marketing and business development efforts by demonstrating the quality and efficiency of their work across online platforms and their corporate website.
KDC contracted WCCTV as a specialist provider of temporary site security and time lapse video production services.
WCCTV provided KDC with three WCCTV Eco Site Towers, one of which was fitted with a fixed high definition camera to capture time lapse video footage.
The WCCTV Eco Site Tower is an all-in-one site security solution that features a long-run battery offering a minimum 150-hours battery backup power – this provides sufficient charge to run the tower overnight or over the weekend, allowing the generator shut down and helping the site save on fuel, reduce noise and adhere to considerate contractor regulations.
As an all-in-one surveillance solution, the system contains wireless transmission (4G/3G and Wi-Fi) of video and alarms, a heavy duty infrared, 360° pan, tilt and 36x zoom camera to allow a remote operator to capture images of any potential intruders, audio speakers to enable a remote challenge to occur.
By deploying the WCCTV Eco Site Towers around the perimeter of works, KDC was able to ensure the site was successfully secured for the duration of the works and that all staff were adhering to health and safety regulations.
In addition, WCCTV provided KDC with a fully edited time lapse video that captured the project in its entirety within days of the project’s completion.
“WCCTV have provided us with a complete service across the project, enabling us to meet a number of our objectives just by using a single system.
Throughout the process, WCCTV have been helpful, reliable and the service we have received has been first-class."
