Pedestal rehabilitation or replacement is difficult when progressed under existing superstructures because of limited access. Furthermore, the safety of the operation is compromised when larger equipment is specified for concrete placement. In order to enhance operational safety and final product quality, it is best to allow a concrete with a smaller aggregate and place it by pumping with a small diameter hose. The Department has historically allowed the use of Class D or DP concrete for pedestals on a case by case basis and this revision only streamlines the process within standard specifications, thus eliminating the need for any project specific requests.
