How do they make sure the prison isn't just employing people already experienced in the field to make the prison money? How do they ensure people are treated fairly (normally prisoners aren't really even allowed sick days, they can't chose not to work overtime if required, etc)? Do they audit to ensure number of sick hours are comparable to non-prison work? Do they ensure prison guards bonus' aren't based on inmate performance (UNICOR does all of the above bad practices resulting in sick people being forced to work overtime in order to get the guards their bonus)?
UNICOR/the Federal system 'strongly encourages' people with CAD experience, etc do the McDonalds remodel contracts, the World Trade Center work, etc. These are people that worked in the industry prior to prison and that are not traditionally been hired back after release, so it's simply being used to make UNICOR money on big contracts based on incarcerated individuals pre-existing training being exploited. In addition having structural CAD work done by people with zero say in their job, their deliverables/quality, their hours, etc seems like a bad idea. I don't know why outside engineers are using this work. The UNICOR McDonalds remodels are probably fine (though you can tell by the current feel of McDonalds that the remodels were literally done by prison inmates), but the UNICOR World Trade Center stuff seems super sketchy.
