Because of the extent of repairs was unknown, those aspects to be repaired were to be mutually agreed upon after the inspection.  Also, the six month time frame for project completion, prior to high demand late spring and summer months, posed a logistics challenge.

Brierley Associates' tradition of service embraces complex and challenging projects. As we move into our sixteenth year of operation, Brierley Associates increasingly takes advantage of geotechnical numerical modeling software such as Midas GTS and other platforms. Dr. Mohamed Gamal, Dr. Eric Lindquist and Phillip Burgmeier lead our modeling efforts. Recent projects include: expansion of underground facilities at Fermi National Accelerator Laboratory in Batavia, IL; evaluation of salt mine behavior in Saltville, VA; and the design of the access shaft to retrieve "Bertha" in Seattle, WA.

NEW TO THE AUSTIN OFFICE

 

https://mlsvc01-prod.s3.amazonaws.com/ce457914101/ab72cccc-51d7-48b3-b068-d9be35f68fa9.jpgBrierley Associates welcomes Charles Luxford to our Austin, Texas office. He adds distinctive structural engineering capabilities to Brierley's services. Charles was raised in Cincinnati, Ohio, the home of the Montgomery Inn and Graeters, which were beloved by the late, great Bob Hope. During his engineering studies at Case-Western Reserve in Cleveland, he had several intern stints with specialty geotechnical contractor Richard Goettle, Inc. After graduating with his Bachelor of Science in Civil Engineering, Charles spent the next 15 years with Kiewit Engineering Co. (KECo) in a design and management role for projects throughout North America. At KECo he was typically involved with several major projects simultaneously, while providing minor support to numerous other projects. Charles' experience includes design, detailing and field support of construction engineering works such as: falsework, formwork, excavation support/earth retention, cofferdams, trestles, marine operations, erection and demolition analysis, heavy and multiple crane lifts, custom rigging, access platforms, rebar cage handling, tower crane foundations, constructability reviews and Design-Build project delivery. Charles holds professional engineering registrations in AZ, CA, CO, FL, NE, NM, NY, and TX.  He is also a registered structural engineer in HI, IL, MA, NE, OK and holds P.Eng licensure in British Columbia and Ontario. "Brierley Associates is delighted that Charles has joined our engineering team. His knowledge and years of hands-on experience will allow us to be even more responsive to our clients' needs on a myriad of heavy civil infrastructure projects across the United States," remarked Brierley Associates Director of Engineering, Dr. Eric Lindquist.

 

Charles may be contacted in our Austin, TX office at 512.219.1733 or by e-mail at cluxford@brierleyassociates.com.

 

 

"SPEAKOUT"

The company's target service evolved into a national reputation as a leader with projects that included: Lake Mead Intake No 3; Caldecott 4th Bore Tunnel; the New Irvington and New Crystal Springs water tunnels; Hudson River PCB Collection Tunnel; Eastside Water Intake and, the award winning Liberty University Twin Box Tunnels. With more than 25 years as a geotechnical engineer, I knew I could bring a lot of expertise to the table, but tunneling wasn't on top of the list.  I remember thinking this might be a professional challenge. It has been and I have enjoyed it.

 

Back in New England, I continued to focus on geotechnical consulting and design, working with A/E firms, contractors and owners.  This would eventually be supplemented with trenchless technology expertise from Nick Strater and Brian Dorwart, and more recently blast design services from Andy McKown.  Meanwhile, Brierley continued expanding in the west, and later added dam expertise in Kentucky, Colorado and Texas.

 

Our team of more than 30 tunneling experts across the country led by Alan Howard, Gregg Sherry and AJ McGinn, currently provide design, contractor pre-bid and value engineering, construction phase design services and claims support.  Some of the current tunneling projects include: contractor services for River Water Supply Conduit 5 and 6; Kaneohe/Kailua Sewer Tunnel and Ohio Canal Interceptor Tunnel.  Brierley recently completed the inspection/repair of the Linnwood Water Tunnel in Milwaukee and designed the access shaft to retrieve "Bertha" in Seattle.

 

Today, Brierley's expertise continues to highlight what we do best - Creating Space Underground.  However, we are also moving "above-ground" with new structural and construction engineering capabilities.  Our tunneling staff and focus has never wavered despite the significant growth and broadening of other specialty design services.  In the end, and reassuring to Gary, we can all still say "we do Tunnels."
