Various Types of Levels Used In Building Construction

Different sorts of levels are utilized in Structural and Architect drawings, and they are utilized to ease understanding. The various kinds of levels utilized in building development are as per the following.
  1. Natural Ground Level (NGL)
  2. Ground Level (GL)
  3. Existing Ground Level (EGL)
  4. Plinth Level
  5. Sill Level
  6. Lintel Level
  7. Floor Finish Level (FFL)
  8. Structural Floor Level (SFL)
  9. Structural Slab Level (SSL)

Natural Ground Level (NGL)

NGL is the condensing of the normal ground level. It is the regular degree of ground before any filling or uncovering.

Ground Level (GL)

GL and FL are the contractions utilized for Ground Level and Floor level, separately.
The term ground level alludes to the structure's level at the ground or closest to the ground level around it. Or on the other hand
The level situated over the outside street and beneath the completed floor level is named ground level.
The term story alludes to every one of the levels of the structure found over the ground level.
The term FGL Finish ground level alludes to the ground that has been done with tiles, grass, paver squares, arranging, or different means.

Building Ground Level (BGL)

The Level of land or the completed floor level inside the structure is known as the Building Ground Level (BGL). The stature of the Building's Ground Level normally goes from 150mm to 1200mm, from the Natural Ground Level (NGL).


One primary justification for raising the tallness of any structure is to limit the section of water inside the structure because of precipitation or tempest. The tallness of the Building's Ground Level might increment in the event that the structure is situated in messy regions as well as in the areas where weighty precipitation is regularly seen.

Plinth Level

A-Level where the foundation closes and the superstructure begins is known as the plinth level. The plinth is a piece of the superstructure situated between the ground level and the completed floor level.
The plinth helps in moving the superstructure's heap to the establishment. It likewise offers security to the structure against infiltration of dampness and a decent engineering appearance.
The basic role of giving a plinth is to forestall the section of water and stormwater into the structure. The soggy confirmation course is additionally presented at the highest point of the plinth, which helps stop dampness development through dividers.
Significance of plinth Beam:-
It conveys a dead heap of block stonework built over it.
It assists with sending a heap of superstructure to the establishment.
It assists with shielding the design from dampness and moistness.
It assists with holding the refill material and goes about as a holding divider.
It assists with bringing down the differential settlement chance of the establishment.
It assists with improving a structure's tasteful appearance.
It additionally assists with keeping sections and dividers associated by going about as a rafter.

Sill Level

A level between the structure's window base and floor level over the ground level is known as the ledge level. The substantial bed or mortar bed is set at the window base level. Stone is likewise utilized at the base level of the window.
Ledge level tallness changes from one space to another and relies upon the room type. For rooms, for the most part, a stature of 1100 mm is embraced because of protection while in the drawing-room, usually tallness of 600-650 is given.
The base required tallness of the ledge level ought to be 44 inches.

Lintel Level

A lintel is a flat part positioned across an opening to help the piece of the construction. It gives bearing for the brickwork over the opening and moves every one of the heaps acting over the opening to the supporting dividers.
Generally, RCC lintel is utilized, however, there are different kinds of lintel like Wooden, stone, and Brick are utilized according to reasonableness.
Entryway and window outlines are not adequately skilled to bear the heap brickwork over the opening. Thusly a different underlying component is given to defeating this issue, which is known as a lintel.

Finished Floor Level (FFL)

The structure's inward floor is done with tiles, marble, stone, or different means; from that point forward, no further completing work is required, known as the completed floor level.
FFL is 150 to 450 mm over the regular ground level with the goal that water and stormwater don't enter inside the structure.
Assuming that the structure is situated in a huge precipitation region and slant, this stature might go up to meters.
