- Natural Ground Level
- Floor Finishing Level
- Existing Ground Level
- Plinth Level
- Sill Level
- Lintel Level
What Is Floor Level?
Ground Level is the full name of G.L. Floor Level is the full name of F.L. The term 'Ground Floor' or 'Ground Level' refers to the street/ground level of a building.
The term "story" is commonly used to refer to all building levels above the Ground Level / Floor Level. It can also refer to the area of land that has not yet been developed.
The 'Natural Ground Level' is the ground level before any excavation or filling, whereas the 'Finished Ground Level' is when it has been 'Finished' with paving stones, asphalt, landscaped grass, and so on.
What Is Natural Ground Level?
(NGL)-Natural Ground Level is known by its full name.
The term "level of the ground" refers to the natural ground elevation.
Typically, the Mean-Sea-Level (MSL) is used to measure the height of the Natural Ground Level (NGL).
Mother Earth has provided us with a natural ground level, and an existing ground level may have been cut or filled, resulting in a different elevation from the original natural ground level.
What Is Floor Finishing Level?
(F.F.L)-The floor Finishing Level is known by its full name. The Floor Finish level refers to the ground level inside the structure. This level is 150 and 450 millimeters above the natural ground level (N.G.L).What Is Existing Ground Level?
E.G.L. complete name of the Existing ground level. This surface area is referred to as the current ground level after the natural ground level above the level surface has been filled with earth. E.G.L. typically follows soil compaction during filling.What Is Plinth Level?
The portion of the superstructure known as the plinth is located between the top of the tie beam at the finished ground level or the top level of the soil surrounding the structure that has been prepared and leveled before construction ( the ground floor level inside the building).
The primary purpose of the plinth height is to shield the superstructure from moisture that might seep in due to direct ground contact. The damp proof course, which offers additional dampness protection, is provided on the top level of the plinth.
This area of the building is directly above the ground, between the floor's surface and the surface of the surrounding ground.
As per Byelaws, the plinth should not be less than 45cm. The basic requirements of the plinth area
- To transfer this superstructure-to-foundation load
- serving as a retaining wall to prevent the filling portion from rising above the raised floor or building
- To prevent dampness or moisture from entering the building
- It improves the building's architectural appearance.
What Is Sill Level?
The sill level refers to the area between a window's base and the floor above ground level. The concrete bed or mortar bed is positioned at the window base level. At the window's base, granite is also used. The sill height varies from room to room and depends on the style of the room.
The top of the window is where the lintel ends. A window sill may be the same width as the brickwork beneath it or broader.
The Sill level is the area between the bottom of the window and the floor above ground level (upward). At the bottom of the window, a bed of concrete or mortar is laid.
The room type for bedrooms and bathrooms determines the sill level's height.
What Is Lintel Level?
The height or vertical measurement from a window or door's bottom edge to its top horizontal component is known as the lintel level. Lintels are installed above windows and doors to transfer the upward wall load to the adjacent wall.
The Lintel level is the elevation between the top of the window and the top slab. Typically, cement mortar or reinforced concrete is used to construct the lintel.
