ENGINEERING ACT OF 1998"
EXPLANATORY NOTE
In a period of scientific and technological advancement, mechanical engineers 
lead the way in conducting tests to evaluate the performance, safety, and efficiency 
of mechanical systems, works, and projects. Mechanical engineering stands as a 
cornerstone for a nation's advancement, playing a pivotal role in fostering innovation, 
technological progress, and economic growth.
However, several provisions of Republic Act No. 8495 or commonly known as 
the Philippine Mechanical Engineering Act, which was passed in 1998, are not fully 
adaptive to today's advancement not only in science and technology but also in 
recognizing the importance of licensed professionals.
Considering this, this proposed measures seeks to strengthen the mechanical 
engineering profession. A supervising licensed professional mechanical engineer in­
charge of mechanical work project or plant in operation shall be allowed to supervise 
multiple establishments under the non-critical classification. This would guarantee that 
projects will be meticulously executed, meeting or surpassing industry standards, 
thereby contributing to outcomes that are both safer and more reliable for the 
community.


In view of the foregoing, the approvai of this biii is earnestiy sought.
