Scope of Work for On-Site Solar PV Ground & Roof-Mounted Systems

1. About the Leo J. Ryan Federal Memorial Building

Facility Address: 1000 Commodore Drive, San Bruno CA 94066-235 Serving Utility: PG&E Original Purpose of Building: Document Storage, Public Reading Room & Administrative Offices Areas available: Roof and ground areas. Areas available are expected to greatly exceed the need to meet the minimum and maximum system requirements, so Contractor has discretion of what areas to use. Selection of areas must be compact and efficient to allow GSA to efficiently expand systems in the future if circumstances warrant.

2. Project Overview

2.1 GSA anticipates this facility being classified as a “net zero” facility, considering both this contract and planned conservation work.

2.2 Through a preliminary site assessment done by DOE─FEMP, it is estimated that the site can accommodate a system larger than what would be needed to achieve 100% of electrical requirements.

3. Specific Requirements

3.1 Maximize annual kWh production from the areas (sqft) made available for the NARA site in order to keep array footprint size small.

3.2 If ground site is utilized for a solar array then the area used must be covered with crushed rock and native vegetation used between rows and around the edges.

3.3 In general eucalyptus trees may be removed as necessary and replaced by shorter native trees.

3.4 Contractor to locate all existing underground utilities prior to any digging or grading.

Existing underground utilities potentially traversing this site include but are not limited to, site drainage, irrigation (supply lines and control wiring), natural gas, electrical, communications, hydrant, sewer and potable water.

3.5 No component of solar system installation or operation to damage or interfere with maintenance of site utilities traversing through solar arrays.

3.6 If ground area is used, Contractor to locate and cap-off sprinklers feeding proposed array area including perimeters of array as delineated on site drawing (Figure 1). Only same material as irrigation pipe can be used to cap off lines; e.g. PVC caps on PVC lines, CPVC Caps on CPVC lines. No temporary caps to be used e.g. rubber caps installed with band clamps.

3.7 If ground area is used, any existing site drainage systems and landscape features designed to keep water out of building; drain pipes, berms, swales, slopes must function fully after installation of solar arrays. Any new drainage volumes or spot concentrations of water created as part of this array installation must be managed by connection to existing system or alternatively, new drainage systems must be installed in array area to manage water runoff. Contractor must maintain positive slopes that drain water away from building.

3.8 If ground area is used, Contractor to prepare ground under arrays in a manner that minimizes weed growth and or facilitates maintenance of unwanted plant growth.

3.9 Array shall be illuminated at night for security purposes with high efficiency (FEMP Designated) solid-state LED security fixtures with full cut-off to eliminate annoyance glare to neighboring properties and to comply with IESNA Dark Sky standards.

3.10 Requirements for Roof Arrays on Main Building
