You appear to have quoted the wrong legal provisions. Looking at the facts mentioned in your question, the correct legal provisions for the offences committed would be Section 30-C (offence by Government officer) and Section 30-A or 30-B (for a person doing illegal construction), as the case may be, of the Ancient Monuments And Archaeological Sites And Remains Act, 1958.
Since these offences appear to be cognizable, you may file a complaint with police with proof. If police does not take action, you can try filing a private criminal complaint in the competent court.
