ABM MALT KILN

The key challenge in the demolition process was the protection and safety of the adjacent residential and commercial properties, the public and the work-force. To safely achieve the goal a full road closure was negotiated with the Highways Authority to allow the tallest section of the structure to be demolished. The closure was agreed at 6 weeks, but by maximising output on all fronts, the period required was reduced to 4 weeks
Resources on site peaked at 14 personnel, together with 5 demolition specification excavators including Volvo EC 235, EC 300, EC 380, EC 480 and EC 700. The Volvo EC 700 was specially modified and up-rated to almost 100t for high reach works allowing it to carry an 8t pulverisor tool at 22m and a 3t pulverisor tool at 33m. Additionally, a crusher, screen and dozer were employed in the MOT Type 1 production and formation of the piling mat.

The fabric of the structure was mainly reinforced concrete, built in a cellular design which formed the malt chutes and hoppers. The actual sequence of demolition was carefully designed using historical information, allowing full confidence in the integrity of the structure as the works progressed.
Recycling of all demolition arisings exceeded over 95%, with all concrete hardcore being processed to either MOT Type 1 or 6F2. All metals were also fully salvaged, sorted and moved on to scrap processing facilities.

GBM Waste Management, a sister division within the Grantham Industries group, dealt with all waste arising from the project, with its yard less than 1 mile from the site. This allowed all material processing, including waste disposal to be kept in-house without the need for transportation of resources into the area. Total hardcore processed from the site was in excess of 18,000t and ferrous metal salvaged just under 1,000t.
The project success was testament to meticulous planning and preparation, and was completed to the full satisfaction of the Client and local residents, without a single health and safety incident.
