Under general supervision, to perform a variety of moderate to complex office and field technical engineering tasks related to drafting, construction plan review, surveying, inspecting, office research and assisting the public; and perform other duties as required.

Distinguishing Characteristics

Classes in this series are alternately staffed, and incumbents typically promote to the next level after one year at the lower level. However, depending upon the complexity of the position's assignment, promotion to the higher level(s) may not occur. This series is distinguished from the lower level Engineering Aide series in that Engineering Technicians perform more complex work and work with a greater degree of independence.

Engineering Technician I is the first working level in the series. Incumbents perform more routine tasks independently and receive closer supervision when assisting in more complex engineering tasks. Incumbents may serve as an instrument person on a survey crew.

Engineering Technician II is the second working level in the series. Incumbents perform moderate to complex technical engineering tasks related to the analysis of construction materials, development plans, specifications and contract administration and inspections. Some positions provide lead direction to subordinates and may have field project responsibility. This class is distinguished from the Engineering Technician III level in that the latter class typically performs more complex or specialized technical engineering assignments, such as project inspection and materials testing, and provides training and supervision to subordinate classes.

Engineering Technician III is the advanced working level in the series. Incumbents perform moderate to complex technical engineering tasks, such as soils and materials testing, encroachment inspections, and serve as lead worker or supervisor, or serve as chief of a field survey crew. This class is distinguished from the Engineering Associate class in that the latter class performs the most difficult and complex technical assignments on a continuing basis, with minimal supervision

Typical Tasks

Set up, adjust and operate theodolite and related engineering equipment and instruments; compute and establish elevations, points, lines and distances for topographic, property and construction surveys; check or set monumentation for subdivision and right-of-way boundaries; calculate grades and alignments and construction quantities and draw plans and profiles; take field notes; maintain office records of maps, plans, boundary descriptions, road and address data and related documents; lay out, draw, trace, check and maintain a variety of special district, property, topographic, reference, address, road and other maps; research property, utility location and title company records; prepare or check legal descriptions, right-of-way maps, encroachments, records of survey maps, parcel maps, subdivision maps, improvement plans, specifications and other engineering documents for conformance to County standards, design criteria and State laws; inspect construction work of contractors to ensure conformance with engineering plans and specifications including roads, subdivisions, sewer and water facilities and other public works projects; approve minor construction changes in the field; process progress payments to contractors; complete Federal, State, and local reports required for construction projects; obtain samples and conducts tests of construction materials such as concrete, asphalt, sand and base rock to ensure that they meet required specifications; conduct soil compaction tests; prepare or obtain material testing reports; design projects using State and County standardized design methodology and design criteria; prepare less complex construction plans and specifications; prepare construction cost estimates and make complex calculations; obtain permits and approvals required from other agencies; assist the public by providing survey records, maps, improvement requirements, interpreting data and resolving complaints; review right-of-way acquisitions; write legal descriptions; prepare reports for litigation and may serve as an expert witness; may supervise subordinate personnel; prepare as-built drawings, reports and correspondence; input, access, and analyze data and generate reports using a computer terminal; organize and maintain computerized and manual files and records.
