This makes sense to this retired old worker.
I`d rather have a trained workforce in the state when it comes to being safe...and efficient, and smart when spending state funds and risking state liability.   To demand people are qualified and safety-trained is no hindrance but a help in achieving that safety and efficiency.
If any of that money is 90% federal match money it means we to have pertinent-safety-trained workers on those jobs.  It (OSHA trenching or confined space-training for example) works to prevent accidents and injuries. 
We have paid out enough in lost lawsuits and watched as untrained workers were killed on the job, and supervisors were?...untrained as well?  Or complacent?  When it comes to working in Alaska, you`d better put safety first as our infrastructure is so far reaching and demanding and costly to maintain, we can ill-afford the costs that preventable tragic accidents cost us all. I hope we have strict-enough educational-enforcement of training requirements.
