A 34 story hi-rise REQUIRES plans and specifications from a NJ Licensed Architect, who in turn has or collaborates with a NJ licensed Electrical Engineer and submits the plans for code compliance to either the local or State for review and release.
The plans and specs are required to be followed, or revisions submitted. Revisions must follow the above requirements.
No offense meant, but you could not do anything without the required design licenses.
