ABSTRACT
A precast concrete structure is an assemblage of precast elements which, when suitably connected together, form a 3D framework capable of resisting gravitation and wind loads. The framework is ideally suited to buildings such as offices, retail units, car parks, schools, stadia and other such buildings requiring minimal internal obstruction and multi-functional leaseable space. The very existence of a precast concrete industry and the numerous successful building projects achieved using precast concrete, for the whole or just a part of the structure, is proof that the technique is practical and economical. Mixed precast and structural cast concrete inevitably lead to it being used with other steelwork construction, materials in a cost effective manner, for example to provide structural continuity using small quantites of cast in situ reinforced concrete, or to form long span steel or timber roofs. Prefabrication factories are not cheap to run.
