Approval of Drawings

Before construction can begin, it is essential to obtain approvals for the architectural and engineering drawings from the relevant authorities. This process involves ensuring that the project complies with building codes and regulations.

Setting the Stage

With the paperwork in place, the next step is to prepare the construction site for the actual building process. This section explores the critical tasks of marking the layout, excavation, and creating the foundation.

Marking of Layout

The approved plans are translated into action by marking the layout on the construction site. The marking of the layout involves several essential steps:

  1. Defining and marking the boundaries of the building plot.
  2. Clearing the ground within and around the layout.
  3. Marking the precise dimensions and orientation of the building, ensuring it aligns with the architectural drawings.


Excavation is a fundamental step that involves digging the earth to prepare the foundation. The excavation process is carried out according to the dimensions and specifications outlined in the drawings. Specialized machinery is often employed to ensure precision and efficiency.

Laying the Foundation

The foundation is the backbone of any building, providing stability and support. This section uncovers the various tasks involved in creating a solid foundation, including compacting the ground, PCC, footing reinforcement, shuttering, and footing concrete.

Compacting the Ground

Before the foundation can be built, it is essential to prepare the ground properly. This involves:

  1. Trimming and dressing the excavation pits to meet the required specifications.
  2. Compacting the bottom of the excavation using hand compactors to ensure it is stable and firm.

PCC (Plain Cement Concrete)

Plain Cement Concrete, or PCC, is the next step in the foundation process. It is used to create a solid base on which the reinforcement and footings will be placed. The mix used, such as 1:4:8 or 1:3:6, is determined by the project’s requirements.

Footing Reinforcement

Reinforcement is a critical component of the foundation. It involves tying together steel bars to create a framework for the concrete. This framework ensures that the foundation can bear the load of the building.


To achieve the desired shape of the concrete and prevent it from coming into contact with the soil, shuttering is employed. The dimensions for shuttering are based on the architectural drawings.

Footing Concrete

Before concrete is poured into the shuttering, it is essential to check the levels of the foundation. Variations in depth and other parameters are adjusted to ensure the foundation is precisely as per the design specifications.

Constructing the Building’s Skeleton

With the foundation in place, the construction process advances to the creation of the building’s structural framework. This section covers column casting and the essential aspects of this crucial phase.

Column Casting

Columns provide vertical support and stability to the building. The casting of columns involves the following steps:

  1. Setting up the shuttering framework to create the shape of the columns.
  2. Pouring concrete into the formwork.
  3. Allowing the concrete to cure, usually removing the shuttering after 24 hours.

Building the Walls

Walls define the structure and layout of the building. This section explores the construction of walls, including the choice of materials, construction methods, and the integration of openings for doors, windows, and ventilators.

Construction of Walls

Walls can be constructed using various materials, including:

  1. Bricks
  2. Wood
  3. Precast concrete
  4. Other materials

Before the main wall construction begins, the base of the wall is constructed using concrete or stone masonry. The height of the walls depends on the floor height, and openings for doors, windows, and ventilators are carefully integrated.

Creating Structural Elements

Lintels and roofing play a crucial role in the structural integrity and protection of the building. This section covers the installation of lintels and the process of roofing, including materials and reinforcement details.


Lintels are horizontal structural elements that provide support over openings, such as doors and windows. The process of installing lintels involves:

  1. Masonry work, where openings for doors and windows are left.
  2. Reinforced cement concrete beams are laid on top of these openings to distribute the loads and ensure the door frames are not directly burdened.


The roof is a significant part of the building’s structure, and its construction is a critical step. The roofing process includes:

  1. Pouring the roof slab, typically using reinforced cement concrete.
  2. Ensuring that the slab’s thickness and reinforcement details align with the approved drawings.

Adding Finishing Touches

Once the structural elements are in place, it’s time to focus on the aesthetic and functional aspects of the building. This section covers plastering, the installation of doors and windows, electrical and plumbing works, tile laying, painting, and other finishing touches.

Plastering Work

Plastering is the process of applying a smooth and even layer to the walls and ceilings. The plastering work includes:

  1. Removing formwork 14 days after slab pouring.
  2. Applying mortar, generally with a mix like 1:3 or 1:4.
  3. Ensuring the thickness of the plaster layer does not exceed 0.75 inches.
  4. Proper curing to ensure the plaster gains strength.

Fixing of Doors and Windows

Doors and windows are essential components of any building. The installation process includes:

  1. Fixing frames in walls during masonry work.
  2. Attaching panels with hinges after the plasterwork is completed.
