supervision of formwork and concreting to ensure that the cast

produce the surface patterns desired. No honeycombing shall be
allowed. Honeycombed parts of the concrete shall be removed by the
Contractor as directed by the Engineer and fresh concrete placed
without extra cost, as instructed by Engineer. All materials, sizes and
layouts of formwork including the locations for their joints shall have
prior approval of the Engineer or the Architect.
Forms and falsework shall be generally cambered as indicated in the
drawings or as instructed by the Engineer. However, for beam up to
5m span and slabs upto 4m span camber is not normally required to
be provided.
