Berti-Lindquist Consulting Engineers changes name to Brierley Associates

Golden Gate Bridge, San Francisco CA

Heavy civil consulting engineering firm Berti-Lindquist Consulting Engineers is proud to announce that as of February 15, 2013 we will be operating as Brierley Associates. This change is the final step in a transition that began on January 1, 2011, when Brierley Associates merged with the firm founded by David Berti and Eric Lindquist. That merger complemented the tunnel design and geotechnical capabilities of Brierley Associates. Although the name has changed, Eric, David, and their team of geo-structural and structural engineers will continue to provide specialty design services to owners, engineers, and contractors for the entire spectrum of heavy civil construction projects ranging from the seismic retrofit of the north anchorage house of the Golden Gate Bridge to the design of the deepest secant pile supported shaft in North Americafor the New Irvington Tunnel project in California.

 


 

The Society of Mining Engineers (SME) has announced  that Dr. Ray Henn has been named as a Distinguished Member.  SME established this class of membership to honor those who have made unusually significant contributions to our industry.

Dr. Henn is a Senior Consultant with Brierley Associates in our Denver, Colorado office.  Ray is known in the tunneling and underground construction industry as a preeminent authority on grouting techniques and their application on underground construction projects as well as his work with claim evaluations and negotiations. He began his career in the heavy and underground construction industry in the 1970’s. Ray’s consulting assignments range from: construction manager; leading tunnel design teams; serving on dispute review boards and as an arbitrator; being appointed to  value engineering teams; and as a member of technical consulting boards.


Dr. Henn teaches grouting techniques and courses in tunneling and underground construction throughout the year. Ray is past president of American Underground Construction Association; recipient of the 2002 American Society of Civil Engineers  (ASCE) Roebling Award in Construction Engineering; and SME’s 2008 Outstanding Individual Award.  He is the author and editor of three tunnel grouting text books for ASCE and has published more than 25 professional papers.
