Class Code: EC2 EC4 EC5 
Analyst:  JF 
Date Originated: 07/87 
Date Revised: 11/94 



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.


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.
