Lucile Packard Children's Hospital Stanford


With a new 521,000 sq ft addition, Lucile Packard Children’s Hospital Stanford more than doubles the size of the existing hospital. The project team focused on the environment inside and out by employing sustainable design practices and giving patients exterior views, natural light, and outdoor access in numerous gardens. SGH consulted on the building enclosure design.

SGH assisted with the design of below-grade waterproofing, exterior glass fiber-reinforced and precast concrete wall cladding, windows and doors, low-slope roofing, and green roofing. Highlights of our work include the following:

  • Worked with the integrated project delivery team to refine the building enclosure assemblies and coordinate details with the different disciplines
  • Investigated as-built conditions at the existing hospital
  • Reviewed the proposed enclosure design and helped the architecture team develop contract documents to clarify the design intent for the building enclosure
  • Developed details to integrate the various systems, including tie-ins to the existing building, new pedestrian corridors, more than 3.5 acres of landscaped plaza areas, and interfaces between assemblies designed by the architects and design-build contractors
  • Provided performance criteria, including testing criteria for walls and plaza waterproofing assemblies, for the project specifications
  • Established mockup requirements and reviewed onsite and laboratory mockup construction
  • Performed construction administration services, including reviewing contractor submittals and visiting the site to observe ongoing construction to compare with the project requirements, witnessing third-party performance testing, and helping the design and construction teams develop solutions to address field conditions
