The base of the complex civil engineering industry is built on accuracy, from perfect vertical plumb walls to building strong foundations. Similarly, Levels in construction are essential when it comes to precision.
There are different types of levels, commonly used in house and building construction, and each serves various purposes to ensure safe and stable structures.
What are levels
Types of levels along with their roles, functions, and importance,
that you should know as a civil engineer or professional involved in the Construction Industry.
What are Levels?
Levels are used to find out the vertical alignment of the surface considering the reference point, typically gravity force. They help to ensure that surfaces are flat and even, thus it makes easy to construct strong and aesthetically appealing buildi
Different types of levels in House and Building Construction. (Definition, Function, and Importance)
Natural Ground Level (NGL):
Natural Ground level refers to the original ground level before the commencement of any construction activity.
Functions: To know the amount of excavation to be done for the foundation and basements depends on NGL. NGL acts as the foundation for all other level references at that construction site.
Importance: The accurate NGL helps in ensuring accurate drainage planning and foundation depth and also helps in the prevention of underground connection problems.
Building Ground Level (BGL):
The Level of land or the completed floor level inside the structure is known as the Building Ground Level.
