Input tax claim

Hai..

I am working in a construction industry. Our firm is doing construction to a PSU and is in composite scheme

 to pay WCT as per Vat Rules.. we also have sub-contractors where there services are utilized in execution of our work.

We are collecting the service tax from our client on our work -contract reciepts.Is there any possibility to claim input of service

tax and use the same in our other sites where we are paying service tax in regular scheme.(our company is having different sites all over india)

Thanks in adavance.
