Cft= cubic feet,

Cum = Cubic meter

1 Cum = 35.38 cft.

Mr.Ahmed, to calculate BBS (Bar Bending Schedule) you should need to have structural drawings of the particular structure. For any structure we start with foundation, we have to calculate the steel required for footing mat and for columns, the reinforcement bars in the columns should be of varying lengths to avoid overlaps of steel at a single place. What you are particularly looking in BBS.

Mr.Vn.Reddy for 9" wall and 41/2" wall we can't calculate the rates on lumpsum basis as we have to know the length and height of the wall. Always the cost of walls will be in CFT or CUM.
First we have to calculate the cost of materials like Cement, Fine aggregate, Bricks and Water reducing agents. Then labour cost involved in construction of the walls. Apart from the above costs we have to add lifting cost of materials to that particular floor and scaffolding erection costs and contractors profit.

i suggest people should expose themselves to real site experiences and come up with a perfect blend, with design, etc. so that there will be seamless flow

let's dwell on excavation a bit. the type of soil in the leventis site for the factory, had very different type of soil strata. if you finish excating some meters away, you will meet weathered rocky grounds. after a while, you will meet sand. after a while, you will meet clayey soil. we covered over 200 meters length and met different soil types. the external trenches were excavated with machines but the internal trenches also carrying underground beams, were excavated with raw labour. those who worked in rocky areas had much more challenges. i'd like contributors to give us a preview of what labour will be, for different soils.

what are you abbreviating with cft? pls explain. anyway, thanks for your contribution

different costruction steps have different labors calculation. we calculate 'man hour' or 'man days'. for example you want to know how many labors are required for a specific work for 1 day then here are some formulae
EXCAVATION : only unskilled labors required, (quantity of excavation in cft/ 113)
CONCRETE WORK : skilled(quantity of excavation in cft/ 40), unskilled(quantity of excavation in cft/ 15)
BRICK WORK : skilled (quantity of excavation in cft/ 40), unskilled(skilled * 2)
PLASTER : skilled (quantity of excavation in cft/ 108), unskilled (quantity of excavation in cft/ 100)

how you calculate laboures ?? is this experience based
