Kindly provide me all type of registers to maintain , or any license to apply?? as i have to prepare list of such compliance to do and accordingly inform the contractor for the preparation.
Expecting your prompt inputs in this matter.

Dear Imran,
Greetings!!
Please note :
a. all civil labours responsibilities' of contractor not the company
b. The land owner has to take permission from land & building department to start construction or extension of the floor. Say 4th floor or 5th floor.
