PROJECT OVERVIEW

• The Northern California Children’s Hospital project was renovated in 2018, doubling the size with a new building
• Sustainability is a core theme throughout the building
• The design included a central control two-wire system with drip irrigation to the many extensive green roof gardens and outdoor spaces. The hospital is LEED Platinum
• The building integrates nature seamlessly into its layout, with almost 4 acres of gardens and green spaces for patients, families, visitors, and staff to enjoy

PROJECT NARRATIVE

• The project was challenging with the many terraces, roof gardens, and catwalk planter boxes
• For the catwalk planter construction observation and raised terraced planting, the IC had to take a 3 hour course on fall protection and wear a fall protection harness whenever on the catwalks or on the raised terrace planters
• The entire site is irrigated using a large underground cistern with the intent to have all the landscaping irrigated with rain and condensate water from the cistern and using little or no potable water
• Coordination with the plumbing and electrical engineers was required to get piping from the point of connection to the various gardens and planters
• The control system is a central controlled weather‐based controller which provides daily weather data to the controller via an on‐site weather station
