ITC- can we claim or not? - Goods and Services Tax - GST

Dear Experts, Can we claim ITC for repairs made to a corporate office situated within the factory premises? What if the corporate office is located at a separate site from the factory, is ITC still claimable? Is ITC claimable for the service involved in tree cutting for road construction and warehouse development? Can ITC be claimed for a rented motor vehicle (including two-wheelers) used by a salesperson for marketing purposes? Is ITC claimable for the laying and repair of a bitumen road within the factory premises? Regards, S Ram
