Which code does this activity belong in?
Engineering Services establishments apply physical laws and principles of engineering to design, develop, and utilize machines, materials, instruments, structures, processes, and systems. They provide advice, feasibility studies, plans and designs, technical services during construction or installation, and project inspection and evaluation. The distinction from Architectural Services lies in engineering's focus on applying scientific and technical principles to functional systems, while architects design buildings and structures emphasizing aesthetic and spatial considerations. Testing Laboratories, by contrast, conduct standardized tests and analyses rather than applying engineering principles to design and development work.
