Formwork. Formwork shall be true to line, level, face and profile and be of robust construction adequately framed, braced, strutted, cramped, tied and propped to restrict deformation due to constructional loads to not more than 3 mm, and to entirely eliminate deformation of the form faces by warping or buckling. Wire ties will not be permitted. Formwork shall be grout – tight under all conditions including vibration when specified or used. Formwork shall be designed to allow prefabrication of conveniently sized elements to facilities ease of handling and assembly, to permit striking without force shock or any damage whatever to the concrete member or formwork faces and to permit the removal of sides without disturbing soffits and soffits without disturbing necessary props. Propping shall be carried down to an approved bearing, shall not be supported by timber floors and shall be arranged that formwork may be lowered smoothly. Re-propping will not be permitted. Provision shall be made for cleaning out and draining. Formwork shall be constructed of material or lined with material as may be necessary to achieve the finishes specified herein and in such a manner as to eliminate screw or nail imperfections. Before each use, form faces shall be treated with the minimum amount of approved mould oil necessary to obtain a clean release. Mould oil shall not come into contact with the reinforcement. The use of cement retarders will not be permitted except where a key for other finishes is required. Before placing of the concrete, bolts and fixing shall be in position and cores and other devices used for forming openings, holes, pockets, recesses, ducts or other cavities shall be fixed to the shuttering. Immediately prior to concreting, formwork shall be thoroughly cleaned out and re-checked. No placing shall commence until the Engineer has inspected the formwork and given his consent for concreting to proceed, but such consent shall not relieve the contractor of his responsibility for its sufficiency. After striking, formwork shall be cleaned, stacked and protected and before re-use shall be serviced, made good or replaced with new as may be necessary to maintain the finish and standard.

Formwork. Descriptions of formwork shall be deemed to include use and waste only (except where described as "left in" or "permanent"), for fitting together in the required forms, wedging, plumbing and fixing to true angles and surfaces as necessary to ensure easy release during stripping and for reconditioning as necessary before re-use. The vertical strutting shall be carried down to such construction as is sufficiently strong to afford the required support without damage and shall remain in position until the newly constructed work is able to support itself.
Formwork. (a) The units of measurement shall be:
(i) General formwork square metre
(ii) Formwork less than 300mm wide metre
(iii) Boxouts, pockets, etc. of stated size number
(iv) Rebates, chases, etc. of staged size metre (b) Method of measurement Subject to the limitations stated below general formwork will be measured as the superficial area of formwork actually in contact with the finished face of the concrete but no deduction shall be made for openings in formwork of 0.4 square metres or less. Formwork shall not be measured:
(i) for forming construction joints (whether shown or not on the Drawings), skewbacks, stunt ends, steppings, bonding chases, keys and the like;
(ii) for forming boxouts, pockets, etc., of stated size that are measured by number;
(iii) for forming rebates, chases, etc., of stated size that are measured by the metre;
(iv) to edge of concrete in blinding layers;
(v) to upper surfaces of concrete inclined at angle of less than 15ΕC to the horizontal.
