Contract Laboure issue

Dear all lawyers,

Our firm is a power project under construction by engaging a lot of contractors. Our coal handling plant is situated at a place which is situated at the premises of a State EB's Power Plant and is 08 Kms from our up coming plant. As a Principal Employer, we only issue Form-V under Contract Laboure Act, enabling all our contracting agencies to obtain licence under CL Act. Now, we engage some contractors in the Coal Handling Plant area where a lot of contsruction activities are being carried out and the place is located within the premises of a State Electricity Board's power plant. Should we issue Form V to the contractors enabling them to obtain licence from the Licencing Officer, for our works carried out in another premises?
