Careers

Soils

Class code: 003676
Bargaining unit(s): 207
Classification title: Transportation Specialist
Function: Soils
Kind of work: Senior level technical and/or specialized work and/or lead work

Nature & purpose

Under limited supervision, an employee in this class performs and directs difficult technical work in the operation of soils and pavement sampling equipment to obtain: soils, rock, pavement samples and groundwater information; develops soils borings to create plans profiles and cross sections to be used in roadway design; develops subsurface exploration logs to be used in foundation design; performs related work as required.

This position 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.  An employee determines what shall be done and how it will be done and continually improves work processes.  At this level, an employee provides technical expertise and information, in a specialized field, to others.

An employee resolves most problems using theoretical principles and concepts of a specialized field as well as knowledge of and impact on the department’s programs.  An employee is considered the technical expert in a specialized area and provides technical support and expertise to others.

An employee is responsible for completing or leading multiple complex 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.

Examples of work

A position may not include all the work examples given, nor does the list include all that may be assigned.

  • Completes or directs the set-up and operates the soils sampling and testing equipment so that soil, pavement samples and ground water information are taken in the right location and in accordance with ASTM, AASHTO, MDH and MnDOT standards.
  • Conducts gravel prospecting and condition surveys so that location and conditions of aggregate or borrow sources are obtained on schedule.
  • Samples materials for wetland mitigation efforts to assist in the delineation and typing of wetlands.
  • Coordinates with Gopher State One-Call and local utilities to assure that all utilities in the area to be drilled are properly identified and located.
  • Performs or directs others to perform operational needs such as traffic control support, assisting in the field staking of sampling locations or acquiring field supplies so that work can be carried out efficiently.
  • Maintains, cleans, monitors performance, safely operates or directs the operation of soils sampling and support equipment so it is in good working order when needed and testing schedules can be met.
  • Performs or oversees the performance of the completion of field in situ tests of soil strengths for foundation design in accordance with standards.
  • Records digital and hand written field data and sampling information and downloads, organizes and archives this information.
  • Plots borings on geometric profiles, plan views and cross sections so that the information corresponds to the existing topography and relates to the proposed location of the future roadway.
  • Assists with the technical certification program training for agency and external personnel.
  • Researches, obtains and prioritizes layouts and profiles of upcoming projects and accurately places soil borings and lab tests on the soils profile so that soils and foundations recommendations can be developed. 
  • Monitors performance of subsurface drainage, geotextiles and geotechnical design features after construction is completed.
  • Assists construction to determine if plans and soils types information is verifiable.
  • Conducts field investigations to determine the type of soils sampling equipment that will be needed.
  • Adjusts or alters the field plan based on conditions encountered so that adequate soils conditions can be determined.
