practice of engineering;
2.  "Professional Structural Engineer", "P.E., S.E." or "S.E."
means an individual who has been duly licensed as a professional
engineer by the Board, and who has been further authorized by the
Board to use the title Professional Structural Engineer, P.E. S.E.,
or S.E., and perform structural engineering analysis and design

services for significant structures based upon education, experience
and examinations as described in Section 475.12c of this title.  For
purposes of this definition, the term "significant structures" shall
not include any structure that is a residential structure;
3.  "Engineer Intern" or "E.I." means a person who complies with
the requirement for education and has passed an examination in the

4.  "Practice of engineering" means any service or creative work
requiring engineering education, training and experience in the
application of engineering principles and the interpretation of
engineering data to engineering activities, including the

property and welfare of the public.  The services may include, but
are not limited to, providing planning, studies, designs, design
coordination, drawings, specifications, and other technical
submissions; engineering reports or material developed in connection
with expert witness testimony or anticipated testimony;
commissioning of engineered systems; and performing surveying that
is incidental to the practice of engineering and reviewing
construction or other design products for the purposes of monitoring
compliance with drawings and specifications related to engineered
works.  Surveying incidental to the practice of engineering excludes
the surveying of real property for the establishment or
determination of land boundaries, rights-of-way, easements, and the
dependent or independent surveys or resurveys of the United States
Public Land Survey System and is limited to conducting field
measurements to supplement the documentation of existing conditions.
Unless a Professional Surveyor has provided the professional
engineer with geocentric/geodetic control coordinates which meet the
accuracy standards set forth in OAC 245:15-13-2, the professional
engineer shall only use a coordinate system based on assumed values
for the project, and so state on the documents.  These services or

any utilities, structures, buildings, machines, equipment,
processes, work systems, projects, communication systems,
transportation systems and industrial or consumer products or
equipment of a mechanical, electrical, chemical, environmental,
hydraulic, pneumatic, thermal, control system or communications
nature, insofar as they involve safeguarding life, health or
property, and including such other professional services as may be
necessary to the design coordination of a multidiscipline work,
planning, progress and completion of any engineering services.
Design coordination includes the review and coordination of
technical submissions prepared by others, including the work of
other professionals working with or under the direction of an

engineer, with professional regard for the ability of each
professional involved in a multidisciplinary effort.
