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

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

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 drg.

Step III Column formwork
-Column formwork is a temporary arrangement for the pouring of concrete.
-we do 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.
