SERIES CONCEPT
Drafting Technicians prepare or supervise the preparation of engineering
schematics and drawings, charts, graphs, maps, and illustrations; and
perform other related duties as required.
Incumbents typically prepare layouts and schematics from engineering design
information and specifications for mechanical, electrical, electronic and
optical instruments and/or systems; prepare plans and specifications for
heating, ventilating air-conditioning, plumbing and electrical systems for
buildings and laboratory facilities; prepare detailed shop and assembly
drawings and material and parts lists for scientific instruments and
apparatus; prepare perspective and isometric drawings; prepare charts, maps,
and graphs from research data; prepare navigational charts for research
expeditions; prepare illustrative materials for reproduction or publication;
and perform engineering and statistical calculations.
CLASS CONCEPTS
Principal Drafting Technician
Under general supervision, incumbents prepare engineering design drawings
requiring originality, independent judgment, knowledge of engineering and
scientific principles, and ability to produce complex drawings of the
highest level of difficulty; perform stress calculations and material analysis
of various components; calculate and specify tolerances and allowances for
components; select, specify, and coordinate procurement of commercially
available components; provide information and instructions to fabrication
shop personnel; and prepare or supervise preparation of detail and assembly
drawings and subordinate layouts.
Incumbents typically work under the supervision of a professional research
scientist or development engineer. These professionals supply general design
objectives and criteria and are responsible for the completed instruments or
systems, the achievement of the objectives specified for the instrument or
system, and/or the interpretation and application of obtained data. The
Principal Drafting Technician is responsible for translating general design
objectives and criteria into specific plans, dimensions, and materials,
which can be turned over to fabrication shop personnel. Incumbents may
carry responsibilities for the work of a small group of Senior Drafting
Technicians and/or Drafting Technicians, but this is not a necessary
requirement for the class.
Examples of assignments allocated to this level of difficulty and
responsibility are:
Supervisor of engineering drafting staff for a scientific or
engineering research laboratory, personally performing the
most difficult engineering design drafting.
Principal Drafting Technician for advanced, complex instrument
systems involving a combination of electrical, electronic,
mechanical, and/or optical components, used in deep water
photography, atmospheric visibility studies, radio and optical
astronomy, or space science instrument packages.
Senior Drafting Technician
Under supervision, incumbents perform all or many of the duties indicated
for the series under the Series Concept. This is the full operational
level for engineering drafting.
Incumbents typically receive nonroutine engineering drafting assignments
that involve application of most of the standardized drawing techniques
regularly used. Assignments are given with fairly complete instructions
and design detail by Principal Drafting Technician or a professional
engineer or research scientist. Original design contributions are not
regularly expected at this level. Incumbents may have Drafting Technicians
for assistants in producing the routine, simple drafting work.
Examples of assignments at this level of difficulty and responsibility are:
Engineering Drafting Technician (civil, electrical or mechanical)
for construction projects, either new construction or alterations,
undertaken by University staff, for general purpose buildings
and/or laboratory facilities, with work subject to checking and
review by the professional engineer responsible for the project.
Detail drafting technician preparing detailed shop and assembly
drawings of instruments and apparatus fabricated for scientific
and engineering research.
Publication drafting technician preparing engineering schematics,
circuit and other diagrams, charts, graphs and maps in final form
for reproduction and/or publication, with knowledge of engineering,
scientific and/or mathematical symbols and terminology as an
essential requirement of the work.
Drafting Technician
Under close supervision, incumbents perform simple drafting tasks, often with
finished work as a guide.
This is the entry level class for the engineering drafting series. Incumbents
have had sufficient training and/or experience to produce an acceptable
quality and quantity of simple, repetitive drafting work without additional
on-the-job training and without being required to have any substantial
knowledge of engineering, scientific and/or mathematical symbols and
terminology. Incumbents typically are expected to progress to the class of
Senior Drafting Technician.
Examples of assignments at this level of difficulty and responsibility are:
Drafting assistant to a Principal Drafting Technician, preparing simple
engineering detail drawings, circuit and other diagrams, charts and
graphs, operating reproduction machines, and maintaining files of
completed work and copies.
Drafting assistant in a publication, engineering, or research
activity, preparing simple schematics, engineering drawings, charts,
maps and graphs, working from explicit instructions and data that
do not require any subject matter knowledge to interpret.
MINIMUM QUALIFICATIONS
Principal Drafting Technician
Three years of college, with a major in engineering, and two years of
experience as a Senior Drafting Technician in the field under consideration;
or four years of experience as Senior Drafting Technician in the field under
consideration; or an equivalent combination of education and experience.
Senior Drafting Technician
Two years of college in an engineering field, including specialized training
in drafting, and at least one year of experience in drafting in the field
under consideration; or an equivalent combination of education and experience.
Drafting Technician
Graduation from high school and six months of specialized training in
drafting, or one year of actual experience in the field under consideration;
or an equivalent combination of education and experience.
