In preparation for a Senate hearing that will be held tomorrow, Caltrans released hundreds of official documents Monday including test results, correspondence, and certified engineering reports that confirm data falsification on test files was limited to one former Caltrans technician and only three structures, and those structures are safe. The records also show no data was ever falsified on the Bay Bridge and the Bay Bridge is structurally sound.

The records released today confirm that a Caltrans employee, who was subsequently fired, falsified data on three projects:

– The La Sierra Avenue Bridge in Riverside in September 2008

– A retaining wall at Braddock Drive on Interstate 405 in Los Angeles in April 2007

– An overhead sign foundation on Interstate 580 in Oakland in March 2008

In a separate and independent review validating Caltrans’ findings, the Federal Highway Administration also concluded that the employee’s falsification was limited to those three structures. Certified engineering reports released today confirm the safety of each of the structures.

The records show that although the former employee worked on the Bay Bridge, none of his work on the bridge was falsified. The records also show that the Bay Bridge is structurally sound.

“We have confirmed that the totality of the problem regarding falsified data is limited to one transportation technician’s work in three locations,” said Acting Director Malcolm Dougherty in a letter sent today to the Senate Committee on Transportation and Housing. “Caltrans performed an engineering analysis to ensure that each location is structurally safe.”
