Rate analysis of R.C.C

ANALYSIS OF RATE OF R.C.C

A correct and reasonable rate per unit work or supply, for a particular item

following its specification and detailed survey of materials, labour, equipments

etc.as required for the unit.work and their prevailing rates may be called as ananalysis of rate.

How to fix up rate per Unit of an item-

(Unit means unit of rate viz, cost of 1 cu m brickwork. 1 cu m concrete work

etc.).

The following five sub-heads are estimated and a summation of these is therate per unit of an item.

(a) Quantity of materials and cost

(b) Labour costs

(c} Costs of equipments or Tools and Plants (T. and P.)

(d) Overhead or Establishment charges (including incidental)

(e) Profit.





ANALYSIS OF RATES FOR CONCRETE WORKS

1) Lime concrete in foundation with 25mm down brick chips

( jhama chips)with 1 lime and two surkhi mortar.

Prop . 1:2: 5.5

Consider first 10 cu m . unit = 1 cu m

Calculation of materials:

summation of proportion = 1+2+5.5 = 8.5

Following the procedure given in article 11-5, SI 32

Lime = 15.5/ 8.5= 1.8 cu m ,

Surki = 1.8 * 2 = 3.6 cu m ,

Brick Chips = 1.8 * 5.5 = 9.9 (say 10 cu m)





2) Lime concrete in foundation with 40mm down stone ballast ,lime and

sand.

Prop . 1:2: 4

Consider first 10 cu m . unit = 1 cu m

Calculation of materials:

Summation of proportion = 7

Following the procedure given in article 11-5, SI 32

Lime = 15.4/ 7

= 2.2 cu m,

Sand = 2.2* 2

= 4.4 cu m ,

Stone ballast = 2.2* 4

= 8.8 cu m
