Hai Dear Employer,
I am a Structural Engineer having around 8 years of work experience, and I am familiar with this kind of work. Your project description is very less. I think you need not only No Objection Certificate, for application of NOC may be needed the technical report. I can give you the proper way of demolishing methods and drawings, the scaffolding details and design and whatever required, everything I can provide to you as a guideline to organize the work.
If you are interested we can discuss more.
