EQUIPMENT MECHANIC SENIOR

3067N3

Pay Grade:  21

DEFINITION OF WORK

Summary

This is highly skilled mechanical work involving the repair and maintenance of gasoline and diesel powered equipment used in the construction and maintenance of highways or other physical settings which are comparable.

Responsible for diagnosing difficult performance problems and improvising replacement, assembly, repair, and troubleshooting techniques when standard procedures do not suffice, and maintaining and repairing a variety of light, medium, and heavy duty equipment. Assignments may include inspecting the mechanical conditions of equipment, or providing training for less skilled mechanics or helpers in highly technical or specialized mechanical work, or providing leadership for an area shop.

Standard Classification Factors

Supervision Received - LEVEL B: "Under general supervision…" Employees working under general supervision usually receive some instructions with respect to the details of most assignments but are free to develop their own work sequences within established procedures, methods and policies. They are often physically removed from their supervisor and subject to only periodic checks.

Difficulty - LEVEL B: Average… Where the employee is confronted with a variety of duties susceptible to different methods of solution which, in turn, places a correspondingly higher demand upon resourcefulness and concentration. Positions which require the analysis and evaluation of raw data and the rendering of conclusions would, in many instances, fall into this category.

Complexity - LEVEL C: Work is of a standardized nature that may involve a variety of duties. Analytical thought becomes more important at this level due to increased data and changing situations. Tasks usually have several steps, some of which may not be directly related. Alternatives may exist for processes or methods to be used in solving problems. Workers at this level exercise a moderate amount of independent judgment. Work is controlled by routine review and reporting to or consultation with supervisors. When guidelines exist at this level, they tend to be more complicated or technical in nature requiring careful interpretation.

Consequence of Actions or Decisions - LEVEL D: Consequences of actions or decisions at this level are significant as the work may be rarely if ever reviewed, making errors difficult to detect. Errors may cause major program failure or a high degree of confusion. Injuries to others due to errors are serious or incapacitating or both and costs due to errors are substantial.

Contacts - LEVEL A: The purpose of the contact is to obtain, clarify, give or screen established factual information, regardless of the type (i.e., easily understood or technical) within a well-defined relationship. Normal communication skills are required.

Physical Demands - LEVEL C: The work requires moderate physical exertion.

Environmental Conditions - LEVEL C: The work environment involves hazards, risks or discomforts typical of working with or around machinery with exposed moving parts, irritant chemicals, heavy equipment or abusive or hostile clientele and patients. Exposure to disagreeable weather conditions and extreme levels of temperature, ventilation, lighting and sound are normal. Protective clothing or gear and specific safety standards or procedures may be required. Serious injury is possible.

Supervision/Leadership - LEVEL A: No supervisory or leadership responsibility; may explain work instructions or assist in training others.

Distinguishing Features

Differs from the Equipment Mechanic Specialist class in which the work includes some managerial responsibility and the complex mechanical work.

Differs from the Equipment Mechanic class in which the repair work requires less skill and is more closely supervised.
