The Northgate Link extension of the Sound Transit Link Light Rail system starts at the southern tip of the University of Washington (UW) Seattle campus and extends northward through the campus in twin-bore tunnels. The tunnels pass 24 UW research laboratories that are identified as being vibration sensitive. UW researchers are concerned that vibration and electro-magnetic interference generated by the light rail system would degrade the research environment and compromise the quality of UW research. A second concern is their ability to attract researchers to the campus if there is a perception that the transit system vibration degrades the research environment. The time frame of interest to the UW is the foreseeable future, perhaps a century or more. To address these concerns Sound Transit agreed to install a vibration monitoring system in the tunnels and use the measured train vibration to identify any trains that create vibration that exceeds the negotiated limits. This paper describes the equipment and procedures used to determine the relationships between the vibration in the tunnel and the vibration at the sensitive spaces.
