Components Of A Building

Components Of A Building:

A building can be divided into two general categories

2. Superstructure:

The portion which is situated above the ground level is called superstructure.

The components of a building can be further classified as under:


1. Foundation:

Foundation is the lowest part of a structure below the ground level which transfers all the loads (dead load, live load etc) to the soil.

2. Plinth:

The Portion of a building between the ground surrounding the building and the top floor just above the ground is termed as plinth. A plinth is provided to prevent the surface water from entering the building.

3. DPC:

DPC or damp proof course is a layer of waterproofing materials like asphalt, bitumen, waterproof cement, etc on which the walls are constructed.

Doors are provided as a barrier secured in an opening left in a wall to access the building, room or passage.

A window may be defined as an opening left in a wall for the purpose of providing daylight, vision, natural air, and ventilation.
