Design-Build services are considered best practices for developing onsite solar PV projects, especially those that involve multiple sites. A summary scope of work being requested from qualified proposers include: • Finalized site selections based on various technical, financial and operational criteria, from a list of 16 potential City sites that includes a combination of roof-top and groundmounted options (fixed tilt or single-axis tracking). • Solar PV design, permitting and interconnection arrangements. • Turn-key project financing such as Power Purchase Agreements (PPAs), with various 10 year, 15 year and 25 year term options. • PPAs would be the required financing mechanism. It is preferred that proposers provide cash based financing strategies for consideration as well, especially for the groundmounted water treatment facility and pump station sites. • Installation and build services such as selection and coordination of construction contractors, schedules and budget, in close coordination with the City.
