Concerning the professional engineers' registration act.

SB 6048 amends Washington's professional engineers' registration act by updating definitions and requirements for licensed engineers and land surveyors. It clarifies the scope of "practice of engineering" and specifically defines "significant structures" requiring engineering oversight - such as hospitals, hazardous facilities, buildings over five stories, and large gathering spaces (over 300 people). The bill directly affects engineers, land surveyors, and construction projects involving these structures, ensuring only qualified professionals oversee high-risk developments. Key provisions include refined definitions for "engineer-in-training" and updated criteria for board membership (e.g., 10 years of active practice). The changes aim to modernize regulatory clarity without creating new licensing barriers.
