1. Design, erect, support, brace, and maintain formwork so that it will safely <br />support vertical and lateral loads that might be applied, until such loads can be <br />supported by the concrete structure. <br />2. Carry vertical and lateral loads to ground by formwork system and in -place <br />construction that has attained adequate strength for that purpose. <br />3. Construct formwork so concrete members and structures are of correct size, <br />shape, alignment, elevation, and position. <br />4. Design forms and falsework to include assumed values of live load, dead load, <br />weight of moving equipment operated on the formwork, concrete mix, height of <br />concrete drop, vibrator frequency, ambient temperature, foundation pressures, <br />stresses, lateral stability, and other factors pertinent to safety of the structure <br />during construction. <br />5. Provide shores and struts with positive means of adjustment capable of taking <br />up formwork settlement during concrete placing operations, using wedges or <br />jacks or a combination thereof. <br />6. Provide trussed supports when adequate foundations for shores and struts <br />cannot be secured. <br />7. Support form materials by structural members spaced sufficiently close to <br />prevent objectionable deflection. <br />8. Fit forms placed in successive units for continuous surfaces to accurate <br />alignment, free from irregularities, and within the allowable tolerances. <br />9. Provide formwork sufficiently tight to prevent leakage of cement paste during <br />concrete placement. Solidly butt joints, and provide backup material at joints as <br />required to prevent leakage and prevent fins. <br />10. Provide camber in formwork as required for anticipated deflections due to <br />weight and pressures of fresh concrete and construction loads. <br />2.4 EARTH FORMS <br />A. Side forms for footings may be omitted, and concrete may be placed <br />directly against excavation, only when requested by the Contractor and <br />approved by the Architect. <br />B. When omission of forms is accepted, provide additional concrete 1" on <br />each side of the minimum design profiles and dimensions shown on the <br />Drawings. <br />PART 3 - EXECUTION <br />3.1 SURFACE CONDITIONS <br />A. Examine the areas and conditions under which work of this Section will <br />be performed. Correct conditions detrimental to timely and proper <br />03100-3 <br />
