project description

The project programmed, designed and constructed a new building addition directly south of the Medical Center’s Pacific Tower on Columbia Road. The expansion was planned for two phases. Phase One included a hospital addition of approximately 163,000 gross square feet (GSF), including a complete mechanical/electrical interstitial level, mechanical basement, and penthouse spaces approximately 10,000 GSF of loading dock and interior renovations and connections to the existing hospital towers; and substantial on-site emergency power, chilled water, and oxygen system infrastructure. This phase provided a new 50-bed Neonatal Intensive Care Unit (NICU), a 32-bed adult surgical oncology unit, diagnostic imaging expansion, shelled space for eight future operating rooms, three shelled entire bed floors, a reconfigured loading dock, and mechanical and electrical infrastructure for current and future expansion needs. Phase Two, a future project, would add up to four additional floors for acute care nursing units.
