No. 560 1.15.4.2 Bottom of beams, girders and ribs, sides of columns shall be made with: a) Steel plates not less than 5mm thick of specified size stiffened with a suitable structural frame, fabricated true to plane with a tolerance of +/-2mm within the plate. b) Timber planks of 35mm actual thickness and of specified surface finish, width and reasonable length. c) Plywood plates not less than 12mm thick, of specified sizes 1.15.5 Erection of Formwork: stiffened with a suitable timber framework. The following shall apply to all formwork: 1.15.5.1 To avoid delay and possible erection of the formwork, the Contractor shall obtain sufficiently in advance, the approval of the Engineer for the design of forms and the type of materials used before fabricating the forms. (Ref ACI 347) Formwork for concrete of equivalent I.S. Code) 1.15.5.2 All shutter planks and plates shall be adequately backed to the satisfaction of the Engineer by a sufficient number and size of walers or framework to ensure rigidity during concreting. All shutters shall be adequately strutted, braced and propped to the satisfaction of the Engineer to prevent deflection under deadweight of concrete and superimposed live load of workmen, materials and plant, and to withstand vibration. No joints in proper shall be allowed.
CIDCO OF MAHARASHTRA LTD C.A.No.01/CIDCO/SE(KHR)/EE(KHR-I)/2010–11 Pg. No. 561 1.15.6 Vertical props shall be supported on wedges or other measures shall be taken where the props can be gently lowered vertically during removal of the formwork. Props for an upper story shall be placed directly over those in the storey immediately below, and the lower props shall bear on a sufficiently strong area. 1) Care shall be taken that all formwork is set plumb and true to line and level or camber or batter where required and as specified by the Engineer. 2) Provisions shall be made for adjustment of supporting struts where necessary. When reinforcement passes through the formwork care should be taken to ensure close fitting joints against the steel bars so as to avoid loss of fines during the compaction of concrete. 3) If the formwork is held together by bolts or wires, these shall be so fixed that no iron will be exposed on surface against which concrete is to be laid. In any case wires shall not be used with exposed concrete formwork. The Engineer may at his discretion allow the Contractor to use tie-bolts running through the concrete and the Contractor shall decide the location and size of such tie-bolts in consultation with the Engineer. Holes left in the concrete by these tie-bolts shall be filled as specified by the Engineer at no extra cost. 4) Formwork shall be so arranged as to permit removal of forms without jarring the Concrete. Wedges, clamps and bolts shall be used wherever practicable instead of nails.
