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.

Cement Masons and Concrete Finishers

B13A experience constructing concrete forms and mixing, placing, finishing, and curing concrete directly overlaps with civilian concrete finishing work.

How to prepare: Prepare a project summary showing your concrete formwork, placement, finishing, and curing experience for review with a concrete contractor when discussing job placement.

What the civilian work involves
  • Check the forms that hold the concrete to see that they are properly constructed.
  • Spread, level, and smooth concrete, using rake, shovel, hand or power trowel, hand or power screed, and float.
  • Monitor how the wind, heat, or cold affect the curing of the concrete throughout the entire process.
