Which method is used for the preparation of detailed estimate?

Detailed Estimate Preparation:

A detailed estimate involves a comprehensive calculation of quantities and costs of all items of work required for a project. This type of estimate is crucial for budgeting, planning, and managing construction projects.

Correct Method for Detailed Estimate Preparation:

• Option 4: Unit Quantity Method
  • The unit quantity method is used for the preparation of a detailed estimate. In this method, the work is divided into various items, and the quantities of each item are calculated. The total cost is then determined by multiplying these quantities by their respective unit rates.
  • This method provides a precise and detailed estimation of the project by considering each component separately, which is essential for accurate cost assessment and effective project management.

Other Methods of Preparing Detailed Estimates:

• Square Metre Method:
  • This method estimates the cost based on the area of the project. It is typically used for preliminary estimates and is not as detailed as the unit quantity method. The cost per square meter is multiplied by the total area to get the approximate cost.
• Cubic Content Method:
  • In this method, the volume of the structure is calculated, and the total cost is estimated by multiplying the cubic content by the rate per cubic meter. This method is often used for buildings and other structures where volume is a significant factor.
• Bay Method:
  • This method involves dividing the structure into bays or sections and estimating the cost for each bay. The total cost is then the sum of the costs of all the bays. This method is useful for large and complex structures.
