CONTRACT AWARDED FOR GOLDEN GATE BRIDGE NORTH

APPROACH VIADUCT PHYSICAL SECURITY

IMPROVEMENTS

 

On Friday, February 24, 2006, the Board of Directors of the Golden Gate Bridge, Highway and Transportation District (District) approved the award of a construction contract for Golden Gate Bridge North Approach Physical Security Improvements.

In fall 2004, a $2.1 million grant was awarded to the District for implementation of physical security improvements at the Golden Gate Bridge. The grant funds are from the U.S. Department of Homeland Security through the federal Urban Area Security Initiative program.

The District, in cooperation with other local, state and federal law enforcement agencies, evaluated the effectiveness of the current security features in place at the North (Marin) Approach Viaduct of the Golden Gate Bridge and determined that additional security features were necessary to improve the existing security system.

The security improvements on the north side of the Bridge will include additional and improved gates and fencing, improved lighting, installation of automated vehicle barriers, installation of new electrical equipment such as sensors and cameras. For example, where Conzelman Road enters District property on the northwest side of the Bridge, a rising road barricade will be installed to replace the concrete K-Rail that has been in place since 9/11 and additional security fencing will be added along Moore Road, the roadway that leads to Lime Point on the northeast side of the Bridge.

The responsive, responsible low bidder was Ghilotti Bros, Inc., San Rafael, CA with a bid price of $2,146,213. This project will be funded using the $2.1 million in U.S. Homeland Security grant funds combined with $985,000 coming from toll dollars, for a project budget total of $3,085,000. The detailed budget for this project is as follows:
