Which of the following is NOT a primary duty of contractors according to Nevada regulations?

In Nevada, contractors have specific responsibilities that focus on managing construction projects effectively and ensuring compliance with industry standards. Among these responsibilities, supervising construction crews, coordinating with local government, and ensuring the project meets safety standards are all crucial roles that contractors are obligated to fulfill as part of their profession.

Providing legal advice to clients is not a primary duty of contractors. While contractors do need to have a basic understanding of legal implications surrounding construction projects, they are not licensed to practice law unless they are qualified attorneys. Their primary focus should be on the execution of construction projects, adherence to building codes, and maintaining safety on-site rather than providing legal counsel. Thus, this option correctly identifies a task outside the typical scope of a contractor's responsibilities in Nevada.
