10. Calculation of the quantity of Rebar material 1) Extra of rebar ① In case of deformed bar, extra is 3% in general when including fixed & splice length of rebar, however, it is proportional to bar size. 16mm or larger : more than 5% extra 3% of 100ton is 100×0.03 = 3ton ② Rebar calculation included extra 3-8% after calculating fixing & splice. Therefore, those works will prevent from the reason of illegal construction practices with correct quantity & regular position carryout of construction by calculating bar-list with shop drawing. ③ If rebar will be processed in rebar processing factory , basically extra is as follows. In construction work 3%, in engineering work 6%, support work 3~4%. You have to consider the economical efficiency and construction carryout efficiency in site after analyzing in advance about extra percentage per rebar size by the criterion per construction carryout area.
