1. DESIGN OF FORMWORK

Formwork is an essential part of concrete construction. It is to give FORM to green concrete as per the structural and architectural requirements. For concrete construction at higher elevations, formwork supporting structure called centering (scaffolding) is necessary. Both can be called as enabling facilities to create permanent Members of a Structure. Design of formwork is the theme of this presentation and the same only will be dealt with hereafter. For small and medium size works, provision of formwork is left to the carpenter’s contractors hitherto experience at site. Naturally this method is more by experimentation rather than proper structural design. For safe, Even if formwork is only intended to be used temporarily, it is crucial to design it as a structural part to ensure its affordability and soundness. The most crucial step is the assessment of the correct weight s from the point of pouring green concrete to the point at which the concrete member gains selfsuppor ting strength. Secondary consequences of the aforementioned loads must be properly taken into account and planned for in the design.
