The RTI Act enables you to carry out an inspection of public works viz. Water hole, fire line, check dam, EPT, Solar fence etc. You can get these measured by a Chartered Engineer and even collect samples of the material for testing. You cannot be denied this right under the pretext that “it is in the core/critical tiger habitat” etc. Please see Section2 (j) (i) & (iii) and Section 3 of the RTI Act.
