in attendance to adjust and correct the position of any reinforcement which may be displaced. The
vibrators are not to come into contact with the reinforcement.
Position and correctness of reinforcement
E Irrespective of whether any inspection and/or approval of the fixing of the reinforcement has been
carried out as above, it shall be the contractor’s sole responsibility to ensure that the
reinforcement complies with the details on the drawings or schedules and is fixed exactly in the

fastenings to prevent displacement, vibration or movement by the weight of materials, men and
plant on same and so wedged and clamped as to permit of easing and removal of the formwork
without jarring the concrete. Where formwork is supported on previously constructed portions of
the reinforced concrete structural frame, the Contractor shall by consultation with the Engineer
ensure that the supporting concrete structure is capable of carrying the load and/or sufficiently
propped from lower floors or portions of the frame to permit the load to be temporarily carried
during construction.
B Soffits shall be erected with an upward camber of 5 mm for each 5 metres of horizontal span or as
directed by the Engineer.
C Great care shall be taken to make and maintain all joints in the formwork as tight as possible to
prevent the leakage of grout during vibration. All faulty joints shall be caulked to the Engineer's
approval before concreting.
D The formwork shall be sufficiently rigid to ensure that no distortion or bulging occurs under the
effects of vibration. If at any time the formwork is insufficiently rigid or in any way defective the
Contractor shall strengthen or improve such formwork as the Engineer may direct.
E The Contractor's attention is drawn to the various surface textures and applied finishes required.
The faces of formwork next to the concrete must be of such material and construction; it should
be sufficiently true to provide a concrete surface which will in each particular case permit the
specified surface treatment or applied finish.
F All surfaces which will be in contact with concrete shall be oiled or greased to prevent adhesion
of mortar. Oil or grease shall be of a non- staining mineral type applied as a thin film before the
reinforcement is placed. Surplus moisture shall be removed from the forms prior to placing of the
concrete.
G Temporary openings shall be provided at the base of columns, wall and beam forms and at any
other points where necessary to facilitate cleaning and inspection immediately before the pouring
of concrete. Before the concrete is placed the shuttering shall be trued-up and any water
accumulated therein shall be removed. All sawdust, chips, nails and other debris shall be washed
out or otherwise removed from within the formwork. The reinforcement shall then be inspected
for accuracy of fixing. Immediately before placing the concrete the formwork shall be well
wetted and inspection openings shall be closed. The erection, easing, striking and removing of all
formwork must be done under the personal supervision of a competent foreman, and any damage
occurring through faulty formwork or its incorrect removal shall be made good by the Contractor
at his own expense.
H After removal of formwork, all projections, fins, etc., on the concrete surface shall be chipped off,
and made good to the requirements of the Engineer. Any voids or honeycombing shall be treated
