Rateanalysis for steel bar requires estimation of materials for Steel work, i.e.
quantity of Steel, and binding wire required for 1kg steel bar work for column,
beam, slab steel bar work, i.e. So, we know that the quantity of steel bar is 1 kg so
we can find out the require material for cutting, binding, and fixing a steel
work in a place.

Most knowing point for rate analysis

When
you start doing rate analysis we must remember these points:

–         
Item for rate analysis (Name of the Item i.e.
PCC, RCC, Steel bar, Brickwork etc. )

–         
Specification (type of material, quality of
material etc.)

–         
Unit (per Sqm, Cum, Rm etc.)

–         
Labour

–         
Material

–         
Overhead (Profit for contractor)

Labour
for brickwork:

1)      Skilled
Labour

2)      Unskilled
Labour

Material
for brickwork:

1)      Steel Bar

2)      Binding
wire 16 Gauge

3)      Tools
& Equipment

Steel Bar Requirement

            We have to calculate amount required for 1 kg
steel bar, the quantity is too small than we can calculate rate of 1000 kg than we
convert amount into per kg. Generally we provide TMT bar so we clearly mention
all the detail of material on its specification.

            We take 10
kg of binding wire for 1000 kg steel work, wire should be of 16 gauge GI binding
wire.

For
1000 kg of Steel bar with  TMT 500,
unskilled labour is required for 12 man-days for Providing of Steel, for cutting
of steel, bending and fixing at site. Skilled labour is required for 12 man-day
for placing, checking of steel work on required line level for 1000 Kg.

Rate analysis of Steel bar work requires
the rate of steel, GI binding wire multiplied with their respective quantity.
Cost of labour and tools and tackles for the steel work  is also calculated. Cost of steel, binding
wire,  labour and tools depend on local
availability and local rates.

When,
quantity of steel, binding wire 16 gauge , labour and tools are multiplied by its
rates, and a contractors profit of 10-20% is assumed, the total sum of the
amount is taken as the cost of 1000 kg of  steel work, which is shown below, rate of
material may varies form place to place.

How to Calculate the weight of steel?

            Weight of steel is generally calculated
by an imperial formula i.e.

            W=(
D²)/162 x L

                        Where
,

                                    D= Dia of
Bar in mm

                                    L=  Length of Bar in meter

Calculate the whole amount
for 1000 kg and divide that amount with 1000 kg quantity for per kg rate. Which
are mentioned above on sample rate analysis
