The Alta Bates Summit Medical Center’s Patient Care Pavilion, Oakland, CA, campus is a state-of-the-art hospital that provides 230,000 ft2 (21,400 m2) of space for 238 medical and surgical beds. The Patient Care Pavilion building consists of an 11-story patient care tower and a two-level basement utility plant with an additional rooftop central utility plant. It was built adjacent to the existing fully operational urban hospital campus (Merritt Pavilion). A combination of low-CO2 concrete and other recycled building products was used to achieve LEED Silver designation.
Over 80% (more than 15,000 yd3 [11,500 m3]) of the concrete contained 50% or more of supplementary cementitious materials, designated as EF50 mixtures. All of the EF50 mixtures contained slag cement at 30% replacement factors and above in combination with Class F fly ash and portland cement. Enhanced performance characteristics included highly pumpable concrete in the self-consolidating concrete wall mixtures, reduced heat generation in mat slab mass concrete mixtures, and improved placement characteristics around highly congested reinforcing bar configurations. In addition to the LEED Silver designation, the project exceeds California Title 24 Energy Standards by 16% and meets all requirements for the Green Guide to Healthcare and Sustainability Practices.
