LABOUR LAW And Shramsuvidha

I am running a one person company which deals in hotel and banquet services. The hotel building is under construction.

I have made agreement with a contractor for labour employment. There is no employee employed in the company till date. And no employee would be employed till the completion of the construction. There are two contractor and both contractor employ maximum 9 labour at a time.

I want to understand whether I need to make any labor registration when there is no labor directly employed by me.

I have received an email from shramsuvidha.gov that they have automatically registered me and can do random inspection. Is there an pre preparation, i need to do.
