Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Construction Supervisor

Supervising construction and utility operations, assisting with schedules, and inspecting construction activities transfer directly to construction site supervision.

How to prepare: Create a civilian project work sample showing a crew schedule, material estimate, and construction inspection checklist.

What the civilian work involves
  • Inspect work progress, equipment, or construction sites to verify safety or to ensure that specifications are met.
  • Supervise, coordinate, or schedule the activities of construction or extractive workers.
  • Coordinate work activities with other construction project activities.
Civilian tools and software (examples)
  • Microsoft Project
  • Microsoft Excel

Civil Engineering Technologists and Technicians

Assisting an engineering officer with construction planning and material estimates transfers to civil engineering project support.

How to prepare: Complete a blueprint-reading course that includes calculating material quantities from civil construction drawings.

What the civilian work involves
  • Calculate dimensions, square footage, profile and component specifications, and material quantities, using calculator or computer.
  • Read and review project blueprints and structural specifications to determine dimensions of structure or system and material requirements.
  • Confer with supervisor to determine project details such as plan preparation, acceptance testing, and evaluation of field conditions.
Civilian tools and software (examples)
  • Autodesk AutoCAD
  • Microsoft Excel
