In this article, we will discuss rate analysis of Earthwork, Plaster and Concrete.
1. What is Rate Analysis?
In order to choose the rate of a particular item is examined carefully and then finally, a rate is determined for that item. This process of selecting the rate of an item is termed the analysis of rate or rate analysis.
2. Purpose of Rate Analysis
The following are the two-man goals of calculating out the rate analysis of an item:
1. To determine the actual cost per unit of items.
2. To examine the item for economic processes and economic uses of materials involved in making the item.
3. Importance of Rate Analysis
The process of rate analysis gives a straightforward sight of different factors, tools & machinery, and services concerned in the manufacturing of finished items.
For example- In the case of brickwork, the raw material is brick which is purchased at a certain rate, then employing mortar (cement: sand) bricks are laid. In laying bricks materials such as cement, sand, water, etc. Is required and all activities are accomplished by Mason and bhisti as required. Now final examination of the rate of brickwork is chosen regarding all these factors.
4. Procedure
The procedure of analyzing the rate per unit of an item has been expressed as follows:
This consists of the following heads:
a. Quantity of materials needed per unit rate of work and its cost delivered at the work zone containing first cost, freight, transportation, sales tax, and insurance charges as a question. In the point when materials like cement, steel, stone chips, and bitumen are provided departmentally, then gain on the cost of materials is not permitted, but the cost of carriages from godown to the work site shall be counted.
b. Several labor or labor hours needed to achieve per unit rate of work and its cost.
c. Overhead or equipment and establishment charges needed to achieve per unit rate of work.
d. Gain while arriving at workable rates, the factors that are to be regarded have already been conveyed.
e. In this rate analysis, all civil materials consider, and all items for various rate analysis sum major rate analyses as per below.
1. Rate Analysis of Earth Work.
2. Rate Analysis of Brick.
3. Rate Analysis of Concrete.
4. Rate Analysis of Plaster.
5. Rate Analysis of EarthWork
As per the below rate analysis of earthwork
Earthwork in an excavation in all types of soil containing banking in 20 cm layers and breaking clods, ramming, and dressing up to construct embankments or fill up ground depressions, lead up to 50 m and lift up to 1.50 m.
As per CPWD minimum labor need of 1 cu.m. excavation man labor is 0.21 per day and female labor is 0.14 per day.
Needed other charges 2 %, Add for Water Charge @ 1% on Items Marked, Add for Contractor’s Profit @15% on Items Marked.
