Receives immediate (Heavy Equipment Mechanic I) or general (Heavy Equipment Mechanic II) supervision of direction (Heavy Equipment Mechanic III), from assigned supervisory or management personnel. Exercises no direct supervision over staff.


Heavy Equipment Mechanic I:  This is the entry-level classification in the Heavy Equipment Mechanic series. Initially under close supervision, incumbents learn and perform routine maintenance and repair of a wide variety of motorized equipment. As experience is gained, assignments become more varied and complex; close supervision and frequent review of work lessen as an incumbent demonstrates skill to perform the work independently. Positions at this level usually perform most of the duties required of the positions at the Heavy Equipment Mechanic II level but are not expected to function at the same skill level and usually exercise less independent discretion and judgment in matters related to work procedures and methods. Work is usually supervised while in progress and fits an established structure or pattern. Exceptions or changes in procedures are explained in detail as they arise.

Heavy Equipment Mechanic II: This is the working-level classification in the Heavy Equipment Mechanic series. Positions at this level are distinguished from the Heavy Equipment Mechanic I level by the performance of the full range of duties as assigned, working independently, and exercising judgment and initiative. Positions at this level receive only occasional instruction or assistance as new or unusual situations arise and are fully aware of the operating procedures and policies of the work unit.

Heavy Equipment Mechanic III:   This is the fully qualified journey-level classification in the Heavy Equipment Mechanic series responsible for performing the more complex work assigned to the series. Incumbents regularly work on tasks which are varied and complex, requiring considerable discretion and independent judgement. Positions in the classification rely on experience and judgement to perform assigned duties. Assignments are given with general guidelines and incumbents are responsible for establishing objectives, timelines, and methods to deliver services. Work is typically reviewed upon completion for soundness, appropriateness and conformity to policy and requirements. Positions at this level are distinguished from the Heavy Equipment Mechanic II level by independently troubleshooting and  performing the more complex vehicle and equipment repairs and maintenance, including special project builds.

This class is distinguished from the Senior Equipment Mechanic in that the latter performs the most complex work assigned to the series, such as the most difficult troubleshooting and repair work and provides technical and functional direction over lower-level staff.

Positions in the Heavy Equipment class series are flexibly staffed; positions at the II- and III-levels may be filled by advancement from the I- and II-levels, respectively; progression to the next level in the series is dependent on (i) management affirmation that the position is performing the full range of duties assigned to the classification; (ii) satisfactory work performance; (iii) the incumbent meeting the minimum qualifications for the classification including any licenses and certifications; and (iv) management approval for progression to the next level in the class series.
