Kent, WA - MVP Provides Injection Systems Used In San Francisco Bay Bridge Retrofit Project

Over Labor Day weekend this year, the California Department of Transportation (CalTrans) replaced a 300-foot section of the San Francisco-Oakland Bay Bridge, connecting the bridge to a temporary detour over Yerba Buena Island.  The detour is part of the Bay Bridge Seismic Safety Projects, designed to bring the structure up to current earthquake standards.  "This traffic shift will allow crews to demolish a portion of the original bridge, and to build a new (permanent connection from the tunnel [on Yerba Buena Island] to the new East Span," according the CalTrans Web site.

MVP was contacted by Quick Bond, one of the material suppliers for the project, to determine if they carried a system capable of injecting a Vinyl Ester resin with 50% ATH.  MVP Sales Representative Gary Kinne provided a demonstration of the MVP High-Volume Infusion System, which was able to handle the volume and material without any problem.  CC Myers, Inc., the company contracted to do the work, was pleased with the results of the demonstration and purchased 5 units to use on the project.

The High-Volume Infusion System was used to inject the resin into a void between the deck plates of the new bridge section.  This material acts as a shock absorber to keep the plates from warping by the volume of traffic over time.

The work needed to be completed within the window of the Labor Day weekend, so it was essential that all "parts of the puzzle" came together efficiently.  "The accomplishments achieved during the Labor Day work reflect the culmination of thousands of man-hours of preparation, planning, strategizing and constructing", according to CC Myers Inc.  "The Labor Day 2009 Bay Bridge Roll-Out/Roll-in Weekend was a great success."
