RCC Building, Concrete Frame Structure of a RCC Building ( an Estimating-Costing ) Example kakakakakakakakukakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakukakakakakakakukakaka Example ( 1) The given drawing is ( explaining plan ) of a concrete frame building located on a land area of 387.5 m with main frontage length of 15.5 m , the building is opened on all sides ( detached from other building or no any building adjacent) . The works are in phase of constructing elements for first covering of the ground floor frame , i.e. ( casting concrete of beams and ceiling slab elements of the G.F ), where constructed works previously was of the elements [( 25 x 15.5 x 0.55 ) m as raft-mat foundation , and 12 columns of size (0.5 x 0.5 x 3.9 ) m]. Note : The stairways and elevators access area of the building are laterally as a shaft box separated from the given area ( 387.5 m?), and the building ( for all sides ) without any extended cantilever ceiling slab. Estimate the quantities of works and required construction materials for ( in-site ) concrete casting of the beams and ceiling slab for the ground floor , where the beams of cross sectional dimension of ( 0.5x0.7 ) m and the ceiling slab of depth ( 0.16 ) m A- quantity of the wood shuttering works ( frameworks ) in ( m) for the : beams ceiling slab B- quantity of the concrete casting works in ( m') C- quantity of the required reinforcing steel rebars in ( ton) for the : beams ceiling slab D- quantities of the required ( cement, sand , gravel and water ) for casting concrete of M15 (or type B) Estimate the totally ( wages, expenses and costs) of the construction works and purchasing of materials, if you know that : a - wood shuttering framework wages with all requirements are 4.2 $/m b- purchasing prices with transporting expenses to the site are : steel rebars 395 $/ton, cement 48 $/ton, sand 9 $/m', gravel 6 $/m and water 2 cent/liter c- wages of steel rebars - reinforcing works with all its requirements are 75 $/ton d- totally wages of ( in-site ) concrete casting work for all its ( labors team, machineries and equipments ) are 15 $/m When the referred construction works are successfully done, and the poured concrete will cured and been hardened , after 2 weeks when wood shuttering framework is opened and unfastened. Estimate the carried loads on the columns in (kg/cm) due to the weights of the casted ( beams and ceiling slab ) and compare that loads ( for checking ) with the allowable minimum design compressive strength of concrete M15 ( or type B). 25 m 0,5 No. of columns 12 with dimension 0.5 x 0.5 m Columns Beams No. of beams 17 with dimension 0.5 x 0.7 m Slab thickness 0.16 m 0,5 8,5 S'SI
