A new factory, on the banks of the Tyne, is to be entitled “Newcaflex”. The steelwork comprises over 800te of mainly lattice frameworks. Steelwork design was by Caunton’s design department, on a D&B arrangement with main contractor Mansell Construction, The building, roughly 83m by 49m in plan, is made up of a large high-bay area which houses the VHAM machine and a lower lean-to structure which houses several cranes and an office block.
The impressive height of this structure is 57.8m(floor to parapet), with an internal clear height to underside of truss of approx. 52m. This is the same as a 20-23 storey building! The columns were fabricated in four lengths. For economy and efficient erection to third column-splice, Caunton used a Tadano ATF45-3 mobile crane. This model has 34 metres of boom, and so with 8.7metres of fly-jib fitted, was able to erect up to and including the third section of column. The High Bay roof is constructed from 40m long trusses. Laced between these trusses are a series of runway beams and a high level multi-storey access pod (erected as one completed element) which give access to the roof, and afford maintenance access to the machine.
The project benefited from Building Information Modelling, BIM, which was coordinated by main contractor Mansell. (By definition, BIM is digital representation of physical and functional characteristics of a facility creating a shared knowledge resource for information about it - forming a reliable basis for decisions during its life cycle, from earliest conception to demolition). In this case, and at the very least, it minimised the chances of clashes between machinery, services and steelwork.
