What is Rate Analysis | Rate Analysis of Earth Work, Brick, Concrete and Plaster

What is Rate Analysis?

The basis of arriving at a correct and reasonable rate per unit.work or supply for a particular item following its specification and detail survey of materials, labour, equipment, etc. as required for the unit work, and their prevailing rates may be called as an analysis of rate.

The procedure of analyzing the rate per unit of an item has been described.

This consists of the following heads:—

• Quantity of materials required per unit rate of work and its cost delivered at work site including first cost, freight, transportation, sales tax, and insurance charges as artists in question. In case when materials like cement, steel, stone chips, and bitumen are supplied departmentally, then profit on the cost of materials is not allowed, but the cost of carriages from godown to work site shall be added.
• A number of labour or labour hours required to complete per unit rate of work and its cost.
• Overhead or equipment and establishment charges required to complete per unit rate of work.
• Profit while arriving at workable rates, the factors that are to be considered have already been described.
• In this rate analysis, all civil items consider and all items for different rate analysis sum major rate analysis as per below.
  • Rate Analysis of Earth Work.
  • Rate Analysis of Brick.
  • Rate Analysis of Concrete.
  • Rate Analysis of Plaster.

Rate Analysis of Earth Work.

• As per below rate analysis of earthwork
• Earthwork in an excavation in all kinds of soil including banking in 20 cm layers and breaking clods, ramming and dressing up for the purpose of making embankments or filling up ground depressions, lead upto 50 m and lift upto 1.50 m.
• As per CPWD minimum labour requirement of 1 cu.m. excavation man labour 0.21 per day and female labour 0.14 per day.
• Required other charges 2 %, Add for Water Charge @ 1% on Items Marked, Add for Contractor’s Profit @15% on Items Marked.

Rate Analysis of Brick.

• As per below rate analysis of brick
• Brickwork with best available local bricks in foundation and plinth in cement mortar 1:3 (1
  cement : 3 fine sand)
• Rate analysis of Brickwork minimum labour requirement 10 cu.m. as below Bhisti 1.80 nos, Coolie 10.00 nos, Mason 3.3 nos, and Helper 3.3 nos. this above labour calculation use experience also recommend by CPWD
• Required other charges 2 %, Add for Water Charge @ 1% on Items Marked, Add for Contractor’s Profit @15% on Items Marked, Transportation Cost 1%, Scaffolding 1% Extra.
