Layout and Design

The layout is the process of marking all the building components on the land from the prepared plan. The layout of construction includes transferring the whole plan of foundations, boundaries of the structure, centerline of the wall, and all other important structural parts on the ground along with the length and width so that the components of buildings can be excavated properly. Designing is the process of establishing the concept of the building on paper in a properly engineered manner.
