The construction process of RCC Column of building and checklist of RCC Column as explain in this 4 steps
What is Column?

• Verticle member of the building
• Transfer the load from the slab, Beam to footing
• The building stands on columns
  
                                                                                          Column 

The basic Construction process of column activity is divided into 4 steps as follows
Step I Layout work of column

• In this, with the help of drawings, we do grid linework on-site as x-axis and y-axis and find the location of the columns with surveying instrument like auto level, theodolite, etc
• After determining the position of columns, we do marking of columns on-field practically
  
                                                                Fig. 1 Layout of footing of column 

Step II Column Reinforcement work

• After marking the column locations, we then start to place verticle bars of steel as per the structural consultant column schedule drawing.
•  we place vertical bars, stirrups, and covering work as per column schedule Drawing

Step III Column formwork

• Column formwork is a temporary arrangement for the pouring of concrete.
• we do the first starter work then we start the shuttering process.
• we are the support of the column shuttering by props and turnbuckle as per site condition.

Step IV Pouring concrete into the column.

• After shuttering checking and taking permission from the client we start concreting work of column
• For concreting, walking arrangements should be done with laborers.

Pouring is done in 2 ways

1.  By manually                                                                                                                                                             the small quantity of concrete volume we normally mix on-site by a mixer and pouring done by wheelbarrow or Ghamela tub.
2. By pumps or concrete pouring machines                                                                                                                                                the large quantity of concrete volume, we use ready mix concrete (RMC) and transportation done by pumps or machines

Column checklist for the construction process of column

• We follow the checklist process on-site as describe the DND Construction format
• Date, location of the column, the grade of Concrete, the grade of steel, drawing details, etc should be filled on a checklist during checking of the column.
• After filling all observations we take the client sign-on checklist and taking permission.
• the checklist is a document that can be used for future use and for the record.
