Rate Analysis for Construction Works: Earthwork, Brickwork, 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 detailed 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:—

1. 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.
2. A number of labour or labour hours required to complete per unit rate of work and its cost.
3. Overhead or equipment and establishment charges required to complete per unit rate of work.
4. Profit while arriving at workable rates, the factors that are to be considered have already been described.
5. In this rate analysis, all civil items consider and all items for different rate analysis sum major rate analysis as per below.
   1. Rate Analysis of Earth Work.
   2. Rate Analysis of Brick.
   3. Rate Analysis of Concrete.
   4. Rate Analysis of Plaster.

Rate Analysis of Earth Work.

1. As per below rate analysis of earthwork
2. 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.
3. As per CPWD minimum labour requirement of 1 cu.m. excavation man labour 0.21 per day and female labour 0.14 per day.
4. 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.

1. As per below rate analysis of brick
2. Brickwork with best available local bricks in foundation and plinth in cement mortar 1:3 (1
   cement : 3 fine sand)
3. 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
4. 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.

Rate Analysis of Concrete.

1. As per below rate analysis of concrete
2. Providing and laying in foundations and plinth cement concrete 1: 5: 10 (1 cement: 5 coarse sand: 10 graded stone aggregate 20 mm nominal & 40mm size) excluding the cost of centering and shuttering.
3. Required other charges 2 %, Add for Water Charge @ 1% on Items Marked, Add for Contractor’s Profit @15% on Items Marked, Transportation Cost 1%,  Wastage Extra Total Cost of 5%.

Rate Analysis of Plaster.

1. As per below rate analysis of plaster
2. Providing and laying in 12 mm thick plasterwork  1: 4 (1 cement: 4 coarse sand: 1) excluding the cost of with material.

FAQs

What is Rate Analysis in construction?

Rate Analysis involves calculating the cost per unit of work or supply by evaluating the quantities and rates of materials, labor, equipment, and overheads required. It helps determine a fair and reasonable cost for a specific construction item.

Why is Rate Analysis important?

Rate Analysis ensures accurate budgeting and cost control in construction projects. It helps in pricing items correctly, comparing quotes, and managing expenses effectively.

What are the main components of Rate Analysis?

The main components include:

1. Quantity of materials and their cost
2. Labor requirements and associated costs
3. Equipment and overhead charges
4. Profit margins and additional charges like water and transportation costs

How is the Rate Analysis of Earthwork calculated?

It includes labor costs, material costs, overhead charges, water charges, and contractor’s profit. For example, costs for excavation, ramming, and dressing are considered, along with additional expenses for water and profit margins.

What factors are considered in the Rate Analysis of Brickwork?

Factors include labor charges, material costs (bricks, cement, sand), scaffolding costs, transportation costs, and additional charges for water and contractor’s profit.

How is the Rate Analysis of Concrete different from other items?

Concrete rate analysis considers materials like cement, sand, and aggregates, along with labor charges. It also includes wastage costs, transportation, and overhead charges specific to concrete work.

What is included in the Rate Analysis of Plasterwork?

It includes labor charges, material costs (cement and sand), wastage of material, scaffolding, transportation costs, and additional charges for water and contractor’s profit.

How are additional charges like water and transportation accounted for in Rate Analysis?

Additional charges are calculated as a percentage of the total cost. For example, water charges might be 1%, and transportation might also be 1% of the marked items.

What role does contractor’s profit play in Rate Analysis?

Contractor’s profit is typically added as a percentage of the total cost to cover the contractor’s margin. In the provided examples, it is usually around 15%.

Where can I find detailed calculations for each type of Rate Analysis?

Detailed calculations can be found in the respective sections of the article, which provide breakdowns for earthwork, brickwork, concrete, and plaster.
