Stage 1 comprised replacing an existing 10,500m2 saw-tooth, asbestos roof and rainwater items with new roof that complied with the BCA, including Section J. Stage 2 required 2,160m2 of new roof sheeting and insulation laid over the existing roof sheeting including all associated rainwater items and removal of redundant plant.
During Stage 1 the factory was required to remain operational during the construction process and the existing clerestory windows were also to be replaced. The works were designed and managed in stages according to workplace requirements. Stage 2 was configured to allow works to continue below the existing roof. DTB’s work comprised site inspection, measurement, research, design, documentation for construction, assistance during the construction period and defects reporting.
Both stages were subject to extremely short construction phases, which impacted the erection methods, the Kingspan roof system and the heat within the factory itself.
