Scope <br />A. Provide design and engineering services for the incorporation of sustainability features <br />into the EAC and Parks Operations Base as approved during the February 5, 2019 <br />BOCC meeting. <br />1. Features for EAC: <br />a. 50 kW photovoltaic (PV) array, roof-mounted, ballasted type system. <br />1. Design assumes PV array is a string inverter system. It is understood <br />that any panels that will not fit on the Parks Base will be re- <br />budgeted/reallocated to the EAC as it is the more economical facility for <br />the system. Our engineers have redesigned the HVAC system to an all- <br />electric variable air volume (VAV) following schematic design due to the <br />rooftop PV system. <br />b. Solar Hot Water System <br />1. Electrical and plumbing engineering work required for tank system. <br />A. Will be incorporated near spaces with largest hot water demands <br />(e.g. kitchen). <br />2. Structural engineers required to recalculate/resize increased deadload in <br />the steel framing. <br />2. Features for Parks Operations Base: <br />a. 50 kW photovoltaic (PV) array similar to the EAC system. <br />DocuSign Envelope ID: E6011B64-57D6-4234-8FF6-D8B498A5444B
