What is Analysis of Rates or Rate Analysis of Civil Works?
Analysis of rates (AOR) or rate analysis of civil works is a process conducted by civil engineers to determine the cost of various activities required for the construction of a project. It involves breaking down the total cost of a project into individual components and determining the cost of each component based on the inputs, resources, and specifications required for that activity.
The AOR is an essential tool used in the construction industry to prepare accurate and detailed estimates for a project. It allows the project team to understand the costs involved in executing each activity, identify areas where cost savings can be made, and make informed decisions during the project planning and execution phases.
The process of AOR involves three main steps: measurement, pricing, and abstracting. In the measurement stage, the quantities of various items required for the construction project are determined. These quantities are then used to calculate the cost of each item in the pricing stage. Lastly, in the abstracting stage, the cost of each item is summarized and presented in a tabulated form.
The AOR considers all the factors that affect the cost of a construction project, such as material costs, labor costs, equipment costs, transportation costs, and other project-specific costs. It also takes into account the quality, specification, location, and complexity of the project.
The analysis of rates is typically prepared based on a standard set of measurement units known as the Schedule of Rates (SOR). The SOR is a document that lists the rates of different items of works, which are generally accepted and used by the construction industry. It serves as a reference for estimating, cost control, and preparation of the project budget.
There are two methods commonly used for AOR: the detailed method and the approximate method. The detailed method involves preparing a detailed estimate for each activity involved in the construction project, taking into consideration all the relevant factors. This method is time-consuming but provides the most accurate cost estimate. On the other hand, the approximate method uses average rates per unit to estimate the overall cost of a project, making it a quicker and less detailed approach.
The AOR also helps in the tendering process, where contractors use it as a basis for bidding on the project. It promotes transparency and ensures that the project is completed within the specified budget.
In addition to its use in construction projects, AOR is also helpful in preparing budgets for maintenance and demolition works, preparing cost estimates for insurance claims, and evaluating the financial implications of any proposed changes in the project scope.
In conclusion, AOR plays a crucial role in the planning, execution, and monitoring of construction projects. It enables the project team to make informed decisions, control costs, and ensure the successful completion of the project within the allocated budget.
