Dibble provided survey and civil engineering design services for new prison complexes for Arizona State Prisons in Perryville, Yuma and Tucson. This project added an additional 4000 inmate beds at separate medium security facilities. The project included a study phase to determine the facility needs and a design phase for improvements at each prison complex.

Improvements included new buildings, access roads, extension of utilities to the sites, perimeter security fencing, a sally port, site paving, site grading, storm water retention and utility services to each of the buildings.
