Engineers authorized to enter lands of third parties under certain conditions.

Engineers are hereby granted permission and authority to go on, over, and upon the lands of others when necessary to make engineering surveys and, in so doing, to carry with them their agents and employees necessary for that purpose. Entry under the right hereby granted shall not constitute trespass, and engineers and their duly authorized agents or employees so entering shall not be liable to arrest or a civil action by reason of such entry; however, nothing in this section shall be construed as giving authority to said licensees, agents, or employees to destroy, injure, damage, or move anything on lands of another without the written permission of the landowner.
