The new San Francisco General Hospital will have 284 beds, 14 operating rooms, and provide the only Level-1 trauma care in the city. The 448,000 sq ft steel moment frame structure will have two levels below grade and eight levels above grade including a mechanical penthouse. Ties to the existing hospital will be made by means of a tunnel at the B1 level and a bridge at the 2nd floor. The building will be constructed on base isolators to withstand a major seismic event.
Due to the unique complexities of the design and construction of this type of building, Webcor Builders will use Building Information Modeling and implement a program of Integrated Project Delivery to achieve the earliest practical engagement of qualified contractors. The early collaboration of key subcontractors with the architectural, engineering and building teams can significantly reduce wasted process steps and errors, resulting in a better designed and built final product.
The project will be built in 4 phases. Phase I consists of site utilities relocation and replacement. Phase II consists of service building modifications and equipment additions. Phase III consists of excavations, foundations and structure frame. Phase IV consists of the new Acute Building Enclosure and build out. The new hospital is seeking a minimum of LEED Silver certification and is expected to open in 2015.
Sustainable features include:
Stormwater Design - Using Best Management Practices, 90% of the average annual rainfall will be captured and treated for reuse onsite.
Reducing Heat Island Effect - A combination of roofing materials with a high Solar Reflectance Index (SRI) and a vegetated roof system will be used to reduce the heat island effect of the roof.
Water Efficiency - 50% of the potable water consumption for landscape irrigation will be reduced by selecting drought tolerant plantings and using high efficiency irrigation fixtures. Building potable water consumption will be reduced by 30%.
Energy Efficiency - The energy consumption of the building will be reduced by 21% from baseline.
Emissions - All refrigerants used minimize the emission of compounds that contribute to ozone depletion and global warming.
Materials & Resources - 95% of the construction and demolition debris will be recycled or salvaged. Materials will be used with recycled content such that the percent recycled constituted 10% (based on cost) of the total materials used. Regional materials will be used such that the percent of regional materials constituted 10% (based on cost) of the total materials used.
Wood - 50% of the new permanently installed wood used will be certified by the Forest Stewardship Council (FSC).
Ventilation - Outside air ventilation rates have been increased by 30% above the minimum rates required to introduce more fresh air into the building.
Low-Emitting Materials - All adhesives, sealants, paints, coatings, composite wood, and agrifiber products will have low Volatile Organic Compounds (VOC's) to increase the quality of indoor air.
Innovation in Design - Green Housekeeping - A comprehensive 'green' cleaning/housekeeping program will be utilized. Pulsed Water Treatment System - A chemical free water treatment system will be used. Educational Program - A sustainability educational program will be publicly available to building occupants.
