What is Rate Analysis?

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.

FAQ

Rate Analysis of Civil Works

Civil Rate Analysis – Construction Cost Estimation is an application that can be used to estimate the cost of construction of different civil engineering works such as overall house building cost and cost estimation based on particular category of construction.

Rate Analysis in Civil Engineering

Rate analysis helps in proportioning the effect of the market on the payments made for construction work. It also helps in determining the construction costs per unit as stipulated in the specifications. The use of rate analysis makes it possible to come up with uniform standards for construction works.

Define Rate Analysis

Rate analysis is the basis for arriving at a correct rate per unit work or supply of work specifications such as labor, materials, and equipment. It can also be defined as the analytical study that leads to the definition of unit rates of work by identifying the basic requirements.

What Is Rate Analysis in Civil Engineering?

Rate analysis, the details about all the operation involved in carrying out the work should be available. The quantities of materials required and their cost should be known and the number of different categories of labours required and the capacity of doing work per labour and their wages per day should be known.

Rate Analysis Is Done for Finding?

Rate Analysis is done to know the current rate of any material.

What Are the Pre-Requisites to Carry Out Rate Analysis?

Here, the list of pre-requisites to carry out rate analysis are as follows.

  • Cost of Material.
  • Cost of Labor.
  • Cost of Equipment.
  • Overhead Charges.
  • Contractor’s Profit.

Rate Analysis in Construction

Pre-construction document and cost analysis is a detailed analysis of the project’s budget estimate, the schedule of values, the construction team, the scope of work, the owner/contractor agreement, the plans and specifications, timeline, and materials in order to determine its constructability.

Civil Rate

Construction Cost Estimation is an application that can be used to estimate the cost of construction of different civil engineering works such as overall house building cost and cost estimation based on particular category of construction.

Rate Analysis for Construction

Rate analysis helps in proportioning the effect of the market on the payments made for construction work. It also helps in determining the construction costs per unit as stipulated in the specifications.

Water Charges in Rate Analysis

Water Charges in Estimation = 1.5 to 2 % 0f the total cost

What Is Rate Analysis in Construction?

Rate analysis is the basis for arriving at a correct rate per unit work or supply of work specifications such as labor, materials, and equipment. It can also be defined as the analytical study that leads to the definition of unit rates of work by identifying the basic requirements.

Procedure of Rate Analysis

The analysis of rates is worked out for the unit payment of the particular item of work under two heads: Materials and Labour.

  • The cost of items of work = Material cost + Labour cost
  • Other costs included to the above cost of items of work are:
    • Tools and Plants ( T & P ) = 2.5 to 3 % of the labour cost
    • Transportation cost (if conveyance more than 8 km is considered.)
    • Water charges = 1.5 to 2 % 0f total cost
    • Contractor’s profit = 10 %

Requirements of Rate Analysis

The rate analysis may be required in construction projects for the following purposes:

  • To compare a project’s cost with the project’s sanctioned capital to take necessary action or regularization of excess or less cost.
  • To workout the budget of the construction project and control the cash flows at various stages of construction work.
  • To find out the irrational rates quoted by the contractors during tendering process.
  • To serve as the basic data in case of dispute between project owner and contractor.
  • For the purpose of tendering. In the case of tendering, the contractor may calculate cost of unit work involved in each construction activity for justified quoting of rates. The client may also require rate analysis to calculate the cost of a construction project.
  • To assess the requirements of quantities of labour, materials, machinery and capital to complete the project.
  • To optimize the use of labor, materials and machinery and to know the alternatives to optimize the resources.
  • To assess the rate of unit work from time to time for payment increase in material or labor costs or any deviations in work specifications, extra items of work to the contractor.

What Is Analysis of Rate?

Rate analysis is the basis for arriving at a correct rate per unit work or supply of work specifications such as labor, materials, and equipment. It can also be defined as the analytical study that leads to the definition of unit rates of work by identifying the basic requirements.

Rate Analysis Definition in Civil Engineering

Rate analysis is the basis for arriving at a correct rate per unit work or supply of work specifications such as labor, materials, and equipment.

Contractor’s Profit in Rate Analysis

Depending on the scale of the project and your local industry, the Contractors Profit in Rate Analysis should comprise about 8-15% of the entire project.

Rate Analysis Is Defined as

Rate Analysis can be defined as the analytical study (qualitative and quantitative) that leads to the definition of a new unit rate referring to a given job or work type, by identifying its basic elements.

Mention the Two Heads in the Analysis of Rates Mens

The analysis of rates is worked out for the unit payment of the particular item of work under two heads: Materials and Labour. The rate of various materials as per specifications for the items under consideration can be chalked out from market survey. The costs of materials are taken as delivered at site of work.

Labour Rate Analysis Civil Work

The rate of labour is based on skills of the labour, such as skilled labour, semi-skilled and unskilled labour. The cost of materials and labours vary from place to place. Thus, the cost of each construction work varies from place to place.

Unit Rate Analysis

Unit rate analysis means the rate of all work. As we are doing the work of concrete casting. So what is the rate at which it works? If the rate is divided into units, it is called unit rate. Example: 1 cu.m. concrete casting rate this concrete rate is the unit rate.
