AGENDA STATEMENT
CITY COUNCIL MEETING DATE: April 1, 2003
SUBJECT: Authorization to Solicit Bids, Lighting for Freeway Underpass
Artwork Project, Contract 03-04
Report Prepared by: Lee S. Thompson, Public Works Director
ATTACHMENTS: 1) Catalog sheet
2) Plans and specifications to be available at the City Council
meeting.
RECOMMENDATION: (~ ~/~J' Authorize Staff to Advertise for Bids
FINANCIAL STA NT: The construction budget for the lighting portion of the project is
$105,950.
DESCRIPTION: As part of the Capital Improvement Program project to install
artwork at the freeway underpasses at Dublin Boulevard and Amador Valley Boulevard, this project
would install a ro~v of light fixtures above the murals on the freeway underpass walls.
The fixtures selected are fluorescent, with a color to approximate daylight so that the colors of the murals
will not be affected. A photometric analysis has indicated that the lighting will be an even wash across
the walls. The fixtures and conduit are to be painted a neutral color that will blend with the artwork.
In addition, it is proposed to provide a dimming control so that the lighting can be dimmed at night.
While the lights will be aimed toward the wall and should be seen only minimally by drivers, Staff would
prefer to reduce the possibility of glare. In the interest of energy savings, it would also be possible to turn
the lighting off completely during certain hours.
Staff recommends that the City Council authorize solicitation of bids for this project.
