For technically qualified individuals or companies, the period of expertise required for the construction of works by a personal or any of the company's partners shall be seven years for a degree holder in civil engineering and ten years for a diploma holder in civil engineering. A relevant education degree plays a major role in turning into a licenced contractor. One should hold a high school diploma or an associate degree so as to become a licenced contractor. An associate degree strictly based on construction technology is important for gaining more expertise in the field.
