0 Rate Analysis

Rate Analysis:

Method of determining the rate per unit of particular item of work considering the cost and
quantities of material, cost of labors (skilled and unskilled), hire of tools and plants,
contractor profit etc. is known as rate analysis.

Rate of material usually takes as the rate delivered at the site of work and includes
the first cost (cost of origin), cost of transport, taxes, etc. If the material are to be carried
from a distant place, more than 8 km, the cost of transportation is also added. The rate of
materials and labors vary from place to place and therefore the rate of different item of
work also varies from place to place.

Purpose of Rate Analysis:

The purpose of rate analysis can be summarized as follows:

 To worked out the actual cost per unit of item.

 To worked out the economical use of materials
 To worked out the cost of the extra items which are not provided in the
contract documents (Bill of Quantities-BOQ)
 To revise the schedule of rate due to changes in construction technique.

Requirement of Rate Analysis:

1. Correct information of the market rate of materials.

2. Correct information of the rate of various categories of labors.
3. Output of labors.
4. Knowledge, rate and outturn of various types of plants to be use in construction
work.
5. Up to date knowledge of construction.
6. Standards norms.
Factor affecting Rate Analysis:
1. Specification of work and quality of materials.
2. Proportion of mix (concrete or mortar)
3. Construction facilities and availability of materials, tools and plants.
4. Location of site.
5. Cost of labors and their availability.
6. Facilities available for transportation of materials and labors to the site.
7. Condition of road to the work site.
8. Overhead charges.

ESTIMATION AND VALUATION 4.0 Rate Analysis

The rate of a particular item of work depends on following:

 Specification of different item of work and materials to be use.
 Quantities of materials and their rates, number of different types of
labors(skilled/unskilled)
 Location of work site means of communication, distance of site from the sources o
materials, rates of transportation, availability of workers.
 Availability of tools and plants different types of equipment for different operation
as per specification.
 Profit and overhead expenses of contractors.

Importance of Rate Analysis:

1. The process of doing analysis gives clear picture of the various types of labors and
materials required for completing the particular work.
2. It can be used frequently to settle the disputes between contractor and client about
the item not included in original estimate.
3. It can be used for the compensation by insurance.

MATERIAL ESTIMATE:

Note:

1. In concrete mix:
 To get dry mix (Cement+Sand+Aggregates) increase 50% to 55% of wet
mix.
2. In mortar mix:
 To get dry mix (Cement sand) increase 30% to 35% of wet mix.
3. In plastering works:
 Firstly, increase 25% for filling in between joints and irregular surface. In
case of ceiling and concrete surface (plain surface) only 10% - 15%
increase of wet mix to get total wet mix.
 Then, to get dry mix (Cement sand) increase 30% to 35% of wet mix.
4. In case stone works:
 To get required stone 15% - 20% increase of total works due to wastage and
dressing.
 Volume of dry mortar mix = 30% to 40% of stone masonry.
5. In RCC work
 To get reinforcement : 1% of volume of RCC
 Binding wire: 1Kg per quintal.

Calculate the quantities of materials requires for the following item of work.

1. 48.5 m³ of brick work in (1:3) cement sand mortar.

2. 15 cm thick Foundation PCC (1:3:6), 0.95 m wide and 42 m long.
3. PCC – M20 for RCC roof 100mm thick 20m wide and 25 m long.
4. 415 m² of 40mm thick cement concrete in floor (1:2:4).
5. 713 m² of 12.5 mm thick cement plaster (1:4).
6. 110 m² half brick thick wall in (1:3) cement mortar.
7. 10 m³ of stone masonry in 1:6 mortar ratios.

Add 5% wastage

∴ Brick required = 1.05 x 25909 = 27205 Nos.

Volume of wet mortar = Total brick work – Actual Vol. of brick (without mortar)

To get dry vol. of mortar 30% increase,

∴ Dry vol. of mortar = 1.3 x 12.45 = 16.90 m3

Total part of mix proportion = 1+ 3 = 4

∴ Required cement = (16.90) ¼ = 4.05 m3

{Unit wt. of cement 1440 kg/ m³, 1 bag cement = 50 kg}

1. Solution
Here, unit of analysis per cum.
Here, Volume of brick work = 1.0 m3
Assume
Brick Size =230mm x 110mm x 55 mm.
Mortar thickness = 10mm
» Brick size with mortar = 240mm x 120mm x 65mm
Vol. of Brick work
Therefore, No. of Brick required =
Vol.of one Brick with mortar
1.0
=
0.24 x 0.120 x 0.065

= 534.18

= 535 𝑁𝑜𝑠.

Add 5% wastage

∴ Brick required = 1.05 x 535 = 562 Nos.

Volume of wet mortar = Total brick work – Actual Vol. of brick (without mortar)

= 1 – x534.18 (0.23 x 0.11 x 0.055)

= 0.26 m3

To get dry vol. of mortar 30% increase,

∴ Dry vol. of mortar = 1.3 x 0.26 = 0.338 m3

Total part of mix proportion = 1+ 3 = 4

∴ Required cement = (0.338) ¼ = 0.0845 m3

{Unit wt. of cement 1440 kg/ m³, 1 bag cement = 50 kg}

= 0.0845 x 28.8

= 2.434 bags

∴ Required sand = 3 x 0.0845 = 0.2535 m3

Let, water cement ratio 0.6,

Quantity of plastering work = 100m²

𝑇ℎ𝑒𝑟𝑒𝑓𝑜𝑟𝑒, Vol. of wet mortar = 100x 0.0125 = 1.25 m3

Firstly, increase 25% for filling in between joints and irregular surface to get

To get dry vol. of mortar 30% increase,

4. Solution
Here unit of rate analysis per 10 m3

Volume of stone masonry = 10 m3

Now to get of volume of stone – increase it by 15% to 20% due to wastage and
dressing during placing.

Hence volume of stone = 10 x 1.15 = 11.50 m3

Again, Take volume of dry mortar 30% - 40% volume of stone masonry due to irregular
shape and size of stone available.

Vol. of dry mortar = 40% of work quantity

= 0.4 x 10 = 4 m3

Total part of mix proportion = 1+6 =7
