Oh, I missed Josh's post somehow.
Disclosing that you're not a licenced engineer doesn't, at least in my jurisdiction, protect you from any claims that you're practicing engineering without a licence.
Our Engineering Act does not allow anyone to do the following without permission of the act:
"(a) engage in the practice of professional engineering or professional geoscience;"
Professional Engineering is:
"practice of professional engineering" means the carrying on of chemical, civil, electrical, forest, geological, mechanical, metallurgical, mining or structural engineering, and other disciplines of engineering that may be designated by the council and for which university engineering programs have been accredited by the Canadian Engineering Accreditation Board or by a body which, in the opinion of the council, is its equivalent, and includes reporting on, designing, or directing the construction of any works that require for their design, or the supervision of their construction, or the supervision of their maintenance, such experience and technical knowledge as are required under this Act for the admission by examination to membership in the association, and, without limitation, includes reporting on, designing or directing the construction of public utilities, industrial works, railways, bridges, highways, canals, harbour works, river improvements, lighthouses, wet docks, dry docks, floating docks, launch ways, marine ways, steam engines, turbines, pumps, internal combustion engines, airships and airplanes, electrical machinery and apparatus, chemical operations, machinery, and works for the development, transmission or application of power, light and heat, grain elevators, municipal works, irrigation works, sewage disposal works, drainage works, incinerators, hydraulic works, and all other engineering works, and all buildings necessary to the proper housing, installation and operation of the engineering works embraced in this definition;"
The calcs are a report that claims adequacy and molen wants someone to use it to help make a decision. There's no ill intent, but It's engineering even if it's disclosed that the person doing it isn't licenced. Honestly, it's probably worse if they know he's an engineer in training because they'll expect some degree of engineering competency over what a layman has. Isn't the whole point of providing calcs that you want them to assume some amount of competency? Otherwise they don't accomplish anything. The buyers obviously not qualified to review them, and if they're going to hire someone to review the calcs why don't they just hire them to review the original problem instead?
