Sign Maintenance

Class code: 003677
Bargaining unit(s): 207
Classification title: Transportation Specialist
Function: Sign Maintenance
Kind of work: Senior level technical and/or specialized work, and/or lead worker.

Nature & purpose

Under general supervision an employee in this class oversees difficult technical sign maintenance planning activities; provides ongoing, daily work direction to a sign crew in the installation, repair, or fabrication of signs to maintain the operational status of the sign program; performs related work as required.

This level is different from the Transportation Generalist Senior in that at the Transportation Specialist level, employees plan and organize work based on deadlines, procedures, and standards. The employee determines what will be done, how it will be done, and continually improves work processes. The employee analyzes field conditions and proposes update(s) to the Traffic Engineer to conform to the standards in the Traffic Engineering Manual. At this level, an employee provides technical expertise and information in sign maintenance and installation to others.

An employee resolves most problems using theoretical principles and concepts of a specialized field as well as knowledge of and impact on MnDOT’s programs. The Transportation Specialist is considered the district technical expert in sign maintenance and installation and provides technical support and expertise to others. A Transportation Specialist is responsible for completing or leading multiple complex sign maintenance projects and/or work activities and has a substantial degree of authority in planning, organizing, and completing work. Some employees at this level may perform as lead worker having considerable freedom to organize human, equipment, material, and other resources as well as prioritize, schedule, assign, direct, guide, and report on the work activities of other state employees.
