Shall not be liable to such penalty the contractor who executes works for another, when on their face the plans which he uses appear to be signed and sealed by an engineer who is a member of the Order or by a holder of a temporary licence, unless he continues such execution after having received a written notice from the Order that the plans and specifications used for such works do not comply with the provisions of subsection 1 of this section.
(3) Any investigator designated by the board of directors may at any reasonable hour enter on the premises where works contemplated in section 2 are carried out for the purpose of verifying whether the provisions of subsection 1 of this section are respected and obtain all the pertinent plans and specifications of engineering works. Such investigator must, if it is requested of him, show a certificate signed by the secretary of the Order, certifying his capacity.
