In approximate quantities method of preparing approximate estimate, wall foundations are measured in ________.

Explanation:

The Approximate Quantity Method is used to estimate the cost of a construction project by calculating the total length of walls in running meters. The total length is then multiplied by the rate per running meter of the wall to obtain a fairly accurate estimate of the cost.

Steps Involved:

1. Dividing the Structure:

   • The structure is divided into two parts:
     • Foundation including plinth
     • Superstructure

2. Calculating Running Meter Rates:

   • Foundation:
     • To find the running meter rate for the foundation, approximate quantities of items such as excavation, foundation brickwork up to the plinth, and damp proof course are calculated per running meter.
     • These quantities are then multiplied by the rates of the respective items to determine the price or rate per running meter.
   • Superstructure:
     • Similarly, for the superstructure, the running meter rate is determined from the approximate quantities of brickwork, woodwork, roofing, floor finishing, etc.
     • The calculated rates for these items are then multiplied by the total length of the walls.

3. Requirements:

   • The plan or line plan of the structure should be available to carry out this method effectively.

 Important Points

• If the question does not specifically mention the "Approximate Quantity Method of Estimation," then the standard practice is to measure wall foundations is in cubic meters (m³).
• However, in the Approximate Quantity Method, wall foundations is measured in running meters.
