In the field of civil engineering, various types of estimates are used to determine the cost of a construction project. These estimates help in planning and budgeting for the project. One such type of estimate is the plinth area estimate. In this type of estimate, the cost is calculated based on the plinth area of the building. However, the courtyard is not considered in this type of estimate.

Plinth area estimate:
The plinth area estimate is a widely used method for estimating the cost of a building. It involves calculating the cost based on the plinth area, which is the total built-up area of the building at the floor level. The plinth area includes all the covered areas of the building, such as rooms, corridors, and other enclosed spaces. It is an important parameter for estimating the cost of building materials, labor, and other resources required for the construction.

Why courtyard is not considered?
The courtyard is an open space within a building, usually enclosed by walls or surrounded by the building structure. It is typically used for outdoor activities, providing ventilation, and allowing natural light to enter the building. However, since the courtyard does not contribute to the built-up area of the building, it is not included in the plinth area estimate.

The courtyard is not considered in the plinth area estimate because it is an open space and does not require the same resources as the enclosed areas of the building. The construction cost of the courtyard is typically lower compared to the built-up areas as it does not involve walls, flooring, or roofing. Therefore, excluding the courtyard from the estimate helps in accurately calculating the cost of the actual building structure.

Conclusion:
In conclusion, the courtyard is not considered in the plinth area estimate. This estimate is based on the built-up area of the building, excluding the courtyard. By excluding the courtyard, the estimate accurately reflects the cost of the enclosed spaces in the building.
