Hello Sonu Verma,

No, not necessary. To become Owner if a Construction Company you just need money to invest and idea to execute (a degree in your hand may help you in applying that knowledge in Business and to understand the strategies and techniques for taking up your Company in profits.)

You can do any course of your choice or interest. There is no such hard and fast rule for it. Most of the Construction Company Owners are not Engineering graduates. But to have grip in the Construction field B.Tech Civil Engineering would be helpful.

Hope this helps you.

Best of Luck!!
