Official description

Solicitation #CL0-6603. Issued by FAS - Purchasing. The purpose of this solicitation is to establish a new contract(s) for City Light’s mobile contact voltage testing program which began in 2010 when utility engineers became aware that underground cable and streetlighting failures could energize street level objects and surfaces. The department has jurisdictional responsibility for approximately 85,000 streetlights in its 131-square mile service territory providing lighting on residential and arterial streets. Several factors can contribute to contact voltage including aging infrastructure, weather, improper installation, rodent activity, copper wire theft, and corrosion. Annual testing for contact voltage is being conducted because streetlights are a vital public service. This solicitation will replace our existing blanket contract 6175 with Osmose Utilities Services Inc which was the result of an assignment of the original blanket contract 4656 with Power Survey LLC.
