Rockdale Medical Center is set to unveil the $5.5 million expansion of its Neonatal Intensive Care Unit, which is doubling from eight to 16 beds, and newly renovated Birth Place wing in a ribbon cutting on Tuesday. The hospital began its expansion and renovation last fall in a response to the demand they were seeing for beds, said RMC CEO Deborah Armstrong. At times, the NICU, a level II center, has already seen up to 16 beds occupied at a time.
