INNOVATIVE ASBESTOS ROOF REPLACEMENT TO KILN BUILDING DUNBAR Tarmac
Key Factors:
Issue: Asbestos, once a preferred building material, poses serious health risks when disturbed, especially in roofing and other construction materials often found at numerous cement plants. A significant part of the asbestos roof to the kiln hall building at Tarmac’s Dunbar cement plant needed urgent replacement whilst avoiding a shutdown so that cement production could continue unaffected. The asbestos sheeted roof had become overloaded due to an accumulated build-up of product waste. Zenith’s world-class in-house engineers performed a structural assessment of the roof and calculated all potential loadings, considering the potential volume of accumulated product waste observed. Solution: Zenith engineers designed a unique innovative suspended platform to provide safe access to the roof. The platform was supported on a runway system, allowing it to be moved along the length of the building as the roof replacement progressed. The design was tailored to meet the client’s requirements for materials loading and unloading locations, ensuring the safe and economical removal of the existing hazardous roof sheeting. Once the design elements were finalized, Zenith procured the fabrication of the specialist access platforms, which were installed by Zenith specialist access operatives. A trial was conducted on-site to load test the specialist access platforms inside the kiln hall building.
