CENVAT CREDIT ON CEMENT STEEL USED IN CONSTRUCTION OF BUILDI

Hi, We are into service industry providing taxable services. We are preparing a new building in NCR where cement and steel are used. Both the items are coming from manufacturer.  My query is "Whether we can take benefit of CENVAT for the amount equal to excise duty we are paying for cement and steel" Pls clarify... If yes please provide reference of relevant rule, section or case study.... Thanks!
