Which one to cast first – Column or brickwork

In building construction, it is generally recommended to construct the columns first and then proceed with the brickwork. This is because columns provide the main structural support for the building, and their placement and alignment are critical to ensure the stability and strength of the structure.

Advantages of casting column before brickwork

Casting columns before brickwork in building construction offers numerous advantages, including:

1. Casting columns first ensures accurate placement and alignment, essential for structural stability.
2. Building columns first establishes a precise and accurate foundation for the rest of the construction, ensuring that all subsequent construction is level, plumb, and structurally sound.
3. Constructing columns before brickwork provides a strong bond between the masonry and RCC structures, providing a stronger and more stable foundation for the building.
4. Building columns before brickwork reduces cracks at junctions and joints, providing a more stable and secure structure, and reducing the risk of damage and collapse.
5. Casting columns before brickwork can minimize the use of formwork materials, reducing costs for the construction project.
6. By casting columns before brickwork, bonding agents and chicken mesh are not required at the joints and junctions, reducing both cost and time for the construction process.

Disadvantages of casting brickwork before the column

When it comes to building construction, building brickwork before columns can have several drawbacks that can impact the safety and overall quality of the structure. Some of the key issues associated with this approach include:

1. Building brickwork before columns can cause problems in construction.
2. Brick masonry around a column can reduce its strength over time.
3. Gaps between brick masonry layers can weaken the structure and cause potential collapse.
4. Brick edges within a column can weaken the structure and make it more susceptible to damage or collapse.
5. Constructing brickwork first can cause inaccuracies and instability in the structure.
6. Building brickwork before columns can alter the original size of the column, causing issues with stability and alignment.

To avoid these problems, it is recommended to construct columns before brickwork for stability, accuracy, and quality in the building structure.

What to do if brickwork has already been cast

If brickwork has already been cast, there are still several steps you can take to ensure the building remains structurally sound and stable.

1. Check the alignment and placement of the columns

Even if the brickwork has been cast, it’s important to check the alignment and placement of the columns. 

This will help you identify any potential issues with the structural stability of the building.

2. Reinforce the columns if necessary

If you find any issues with the alignment or placement of the columns, you may need to reinforce them to ensure they are properly supported and stable.

3. Use proper techniques for bricklaying

If you are continuing with the brickwork, ensure you are using proper techniques for bricklaying, such as ensuring level courses and proper mortar joints. 

This will help to maintain the structural integrity of the building.

4. Add additional support

Depending on the specific circumstances of the building, you may need to add additional support to ensure the building remains stable. 

This could include adding additional columns or beams or using tie rods to provide additional support.

5. Seek professional advice

If you are unsure about how to proceed, it’s always a good idea to seek professional advice from a civil engineer/structural engineer/architect or an experienced contractor. 

They can guide you on the best course of action to ensure the building remains structurally sound and stable.
