Five constructions workers in orange jumpsuits and hard hats on four levels of a construction project.
convicts that are working construction do a large project together
The orange jumpsuits can mean something other than the construction workers are convicts.  The workers may not be working at this time.  The workers may be working on something other than construction that just happens to be located at the construction project.  The project the workers are working on may be a small project only located in the larger construction project.  The workers may not be together.
