What Is Rate Analysis? | Rate Analysis For Brickwork, Earthwork, Concrete & Plaster

 What Is Rate Analysis?

The construction project consists of multiple activities. All of the activities have a cost associated with them. The cost of completing an activity majorly involves the material cost, labor cost, equipment cost.

However, some other expenses are minor and fixed. Furthermore, rate analysis is a method for identifying the actual cost of a job unit. It is both quantitative and qualitative.

Therefore, the actual cost of the job is determined by calculating the requirement of material, labor, and equipment required to complete the job. Subsequently, the requirement and specification of the same determine their respective cost.

Other than the fair price calculation, rate analysis also identifies the process of job, materials, and equipment required to conduct a job. This article enlists the general steps for rate analysis and rate analysis for brickwork, earthwork, concrete, and plaster.

What Data Is Required For Rate Analysis?

Rate analysis requires multiple inputs and needs a holistic approach. It needs a complete and detailed analysis of a job life-cycle. Following is the information required for rate analysis.

1. Material Cost

First, calculate the material required to complete a unit of job. Now, determine the market price of the material and the material landing cost at the site. The material site landing cost includes the following aspects-

·         Material market cost

·         Packing cost

·         Loading cost

·         Transporting cost

·         Unloading cost

·         Storing cost

·         Taxes & Customs etc.

2. Manpower Cost

The manpower cost corresponds to the workforce engaged in completing a job unit. Two methods calculate the manpower-

·         Based on productivity.

·         Based on previous experience.

Also, the requirement of each class of manpower (skilled and unskilled) is determined. Since the daily wages of skilled, semi-skilled, and unskilled manpower are different, therefore it is necessary to calculate the requirement of each manpower type separately.

The labor may be deployed through a sub-contractor or directly employed. For directly employed labor, indirect cost is increased for their accommodation, transportation, insurance, food, leaves, etc.

3. Equipment Cost

The equipment may be purchased or rented depending upon the quantum of work to be done. The equipment, tools, and tackles include general and specialized tools. The plant machinery cost includes their operation and maintenance.

The cost includes spare parts, oiling, greasing, periodic maintenance, operator salary, upgrade, setting up and transportation, interest capital, and depreciation.

4. Overheads

There are fixed and variable overheads. The overheads include all the indirect expenses are incurred in performing a job. The fixed overheads are office establishment, furniture, IT, storage sheds, labor accommodation, toilets, fencing, approach road, drinking water, electricity, and telephone.

The variable overheads are the running cost, for example, interest on debt, salaries of indirect staff, stationery, utility bills, office refreshments, office maintenance, housekeeping, fuels, oils, tax, penalties, and scaffolding material.

5. Profit

The profit includes the net amount a contractor shall earn by working on the job. The profit is decided to accommodate the minor price variations and risks. The profit is generally 10% of the project cost.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...

What are different diameters of steel used in construction field?

         In the construction industry, the appropriate selection of materials is crucial as they form            the fundamental basis for determining the strength and durability of structures. TMT (Thermo-Mechanically Treated) Steel is one of the essential components in construction as it stands out for its exceptional strength and ductility in building structures. Thus, contributing to the prolonged longevity and durability of the structures. In this article, we will delve into the different sizes of  TMT steel bars  and their different uses in the construction industry. These TMT Steel bars come in different sizes based on their varied diameters. The different diameter of steel bars are as follows: 8mm Steel Rod 10mm Steel Rod 12mm Steel Rod 16mm Steel Rod 20mm Steel Rod 25mm Steel Rod 32mm Steel Rod, etc TMT bars of varied sizes, play a pivotal role in diverse infrastructure initiatives, the versatility of TMT bars is ...
