Requirements of a Good Formwork

The essential requirements of formwork or shuttering are:

a)      It should be strong enough to take the dead and live loads during construction.

b)      The joints in the formwork should be rigid so that the bulging, twisting, or sagging due to dead and live load is as small as possible. Excessive deformation may disfigure the surface of concrete.

c)      The construction lines in the formwork should be true and the surface plane so that the cost finishing the surface of concrete on removing the shuttering is the least.

A formwork should be easily removable without damage to itself so that it could be used repeatedly
