Various Types of Levels Used In Building Construction

diverse levels for construction

Did you know that the accuracy and stability of buildings in the construction industry heavily rely on the use of different types of levels?

These levels play a crucial role in determining ground levels, plinth levels, sill levels, lintel levels, and finished floor levels. Architects, engineers, and construction professionals need to understand these levels to ensure the structural integrity of a building.

In this article, we will explore the significance and applications of these different types of levels, highlighting their role in ensuring stability, functionality, and aesthetic appeal in building construction.

Key Takeaways

  • Natural Ground Level (NGL), Ground Level (GL), and Building Ground Level (BGL) are important terms in building construction.
  • Plinth Level acts as a transition between the foundation and the superstructure, providing support and protection against moisture.
  • Sill Level is the level between the window base and the floor level, with its height varying based on room type and privacy requirements.
  • Lintel Level is a horizontal element placed across an opening to support the structure and transfer loads to supporting walls.

Ground Levels

Ground levels play a crucial role in building construction as they determine the initial level of the ground and the levels of the structure in relation to the ground. Proper leveling techniques are of utmost importance to ensure the stability and integrity of the structure.

One common challenge in maintaining ground levels during construction is uneven ground surfaces, which can lead to uneven settlement of the structure and potential structural damage. Another challenge is the presence of buried utilities or obstructions, which can hinder the leveling process and require careful excavation.

Additionally, changes in ground elevation due to factors such as soil erosion or natural topography can pose challenges in maintaining consistent ground levels. Therefore, it is essential for builders and construction professionals to employ accurate leveling techniques and address these challenges to ensure a solid foundation and safe construction.

Plinth Level

The plinth level's primary function is to mark the transition between the foundation and the superstructure, ensuring proper load transfer and protection against moisture penetration.

The plinth level is of utmost importance in foundation design because it helps in distributing the loads from the superstructure to the foundation. This ensures that the structure remains stable and does not experience any settlement issues.

Plinth beams are commonly used in the construction of plinth levels. These beams are usually made of reinforced concrete (RCC) or plain concrete and are designed to carry the dead load of the masonry constructed above them.

RCC plinth beams are particularly popular because of their strength and durability. Other materials such as steel and timber can also be used for plinth beams, depending on the specific requirements of the construction project.

Sill Level

Since sill level plays a crucial role in determining the height and placement of windows in a building, it is essential to understand its significance in the overall construction process.

Privacy considerations are taken into account when determining the sill level. For example, bedrooms require a higher sill level to ensure privacy, while drawing rooms may have a lower sill level for better visibility.

The materials used for sill level construction typically include stone or concrete at the base level of the window. This provides a sturdy and stable foundation for the window and helps to prevent moisture penetration.

Lintel Level

One common type of level used in building construction is the lintel level, which is a horizontal element placed across an opening to support the structure.

The lintel level is of great structural importance as it provides support for the masonry above the opening and transfers loads to the supporting walls. It ensures that the door and window frames are not overloaded and can function properly.

RCC lintels are commonly used for their strength and durability, but other materials like wood, stone, and brick can also be used for lintel construction. These materials are chosen based on factors such as the size and weight of the opening, the load to be supported, and the desired aesthetic appearance.

The lintel level plays a crucial role in maintaining the structural integrity of the building and should be designed and constructed with care.

Finished Floor Level

What is the purpose of the Finished Floor Level in building construction?

The Finished Floor Level (FFL) is the internal floor of the building that is finished with tiles, marble, or other materials. FFL serves several important purposes in building construction:

  • Importance of proper drainage at finished floor level. FFL is typically raised 150 to 450 mm above the natural ground level to prevent water and stormwater from entering the structure. This helps to protect the building from water damage and keeps the interior dry and safe.
  • Different materials used for finishing the floor at finished floor level. FFL allows for various materials to be used for finishing the floor, such as tiles, marble, or other types of flooring. This gives the interior of the building a polished and aesthetically pleasing appearance.
  • Level surface for walking. FFL helps to maintain a level surface for walking, providing stability and ease of movement within the building.
  • Finished appearance to the interior. FFL provides a finished and professional appearance to the interior of the building, enhancing its overall look and appeal.

Roof Level

The roof level, undoubtedly, plays a crucial role in the overall structure and functionality of a building. It is the final level of a building and is designed to provide protection from external elements such as rain, sun, and wind. The design of the roof depends on various factors such as the climate, building type, and architectural style. The roof design should be strong and durable to withstand the weight of the structure and any additional loads such as snow or equipment. Additionally, roof waterproofing is essential to prevent water leakage and damage to the building. Proper waterproofing techniques and materials should be used to ensure the longevity of the roof and the integrity of the building.

Mezzanine Level

The mezzanine level, situated between two main floors, serves as an intermediate level in a building's construction. It is a versatile space that can be used for various purposes, providing additional floor area without the need for expanding the building's footprint. Here are some key points about the structural design and mezzanine construction techniques:

  • Structural design:
  • Mezzanines are usually supported by columns or beams, which transfer the load to the building's foundation.
  • The design must consider factors such as load capacity, safety regulations, and accessibility.
  • The height of the mezzanine should be sufficient for people to move around comfortably.
  • The layout should allow for efficient utilization of space.
  • Mezzanine construction techniques:
  • Mezzanines can be constructed using different materials, such as steel, concrete, or wood.
  • Steel is commonly used due to its strength and versatility.
  • The construction process involves erecting the supporting structure, installing the flooring, and adding necessary finishes.
  • Safety measures, such as guardrails and fire protection, should be incorporated into the design.
