To confirm if column present or not, either:

1. go to your local municipal authority Building Department, request to review the structural plan. They may let you take some photos. If not, ask to review building plan - the engineer's contact is in there and you can call them. If nobody layan, then ...

2. choose a spot, chip off plaster to reveal inside - you will see either brick or RC.
