We are pleased to announce that Bennett Trenchless Engineers’ employee Kate Wallin has been elected to the Board of Directors for the Western Chapter of the North American Society for Trenchless Technology (NASTT). The Western Chapter of NASTT is a multi-disciplinary society of individuals and organizations with professional, utilitarian, or environmental interests in Trenchless Technology. The Western Chapter of NASTT (WESTT) promotes the NASTT mission within our western region of Arizona, California, Hawaii, Nevada, and New Mexico.
Bennett Trenchless Engineers is pleased to announce that Sam Ko has joined the firm as an Associate Engineer. Sam is a recent engineering graduate of Sacramento State University. Welcome to the Trenchless Industry, Sam!
Bennett Trenchless Engineers will be presenting at the North American Society for Trenchless Technology’s Annual No Dig Conference at the Gaylord National Hotel in Washington, DC from April 9th to the 13th. On Sunday, April 9th, Matthew Wallin will be teaching the Introduction to New Installations Short Course, covering topics including horizontal directional drilling (HDD), auger boring, pilot tube, open-shield pipejacking, microtunneling, and earth pressure balance pipejacking. During the conference, Kate Wallin will be presenting a paper on the design details that can become pitfalls for small HDD projects, with application for other trenchless construction projects. On Wednesday and Thursday, David Bennett and Mary Neher will be instructors for the newly revised HDD Good Practices Short Course. The HDD course covers HDD projects from design through construction, and includes an in depth analysis of the design calculations required for analyzing risks of hydrofracture, pullback pipe stresses, and settlement.
Matthew Wallin will be teaching a portion of NASTT’s Introduction to Trenchless New Installation Course at the Rocky Mountain Regional NASTT Chapter’s Annual Trenchless Elevated Conference, Oct 5-6. The conference provides a venue to network with like-minded underground professionals, learn about the practical, social, environmental and cost-saving benefits of trenchless technology, and find trenchless exhibits showcasing new construction and rehabilitation products/services. The first day of the 2-day conference includes presentations from chapter members on various trenchless rehabilitation and new installation projects. On the second day, both the New Installations and Rehabilitation short courses are being offered.
Bennett Trenchless will be attending the 12th Annual Western Regional No-Dig Conference, Exhibition, and Short Course from October 17th to 18th at the South Point Hotel in Las Vegas, NV. On Monday, October 17th, Mary Neher will be presenting a case study of a large diameter pipe ram installation of a storm culvert designed by Bennett Trenchless and constructed in 2015. The presentation will cover the project from design through construction. Matthew Wallin will also be attending the conference as a board member of WESTT and servicing as emcee for the event.
Bennett Trenchless is pleased to announce that Mary Neher has received the Trent Ralston Award for Young Trenchless Achievement. The annual award recognizes a young individual who has demonstrated excxellence in the early stages of his/her career and who has made a valuable contribution to the trenchless technology industry. Ms. Neher was chosen based on the strength of her numerous technical publications, her experience in trenchless design, and her participation as volunteer instructor for NASTT’s HDD Good Practices Course. Ms. Neher received her award at the No Dig 2016 Conference in Grapevine, Texas at the Gala Awards Dinner on March 22. Congratulations, Mary!
Ms. Wallin presented at the Northern California Pipe User’s Group (NorCal PUG) annual Sharing Technologies Seminar on February 18, 2016 at HS Lordship in Berkeley, CA. The presentation discussed a project Bennett Trenchless designed for HDD installation of twin siphons beneath the Tuolumne River in Modesto, CA. The twin 18-inch FPVCP siphons were each approximately 675-feet long and were constructed in the winter of 2014/2015 by Mozingo Inc. from Oakdale, CA and the HDD Company of Cameron Park, CA.
David Bennett and Mary Neher presented at the 2nd Annual HDD Academy on February 11 and 12 in Tempe, AZ. The two-day course included presentations from horizontal directional drilling experts on planning, design, and construction of HDD projects. Dr. Bennett discussed geotechnical site investigations and the impact of soil characteristics on HDD design, including evaluation of settlement risk. Ms. Neher discussed methods for evaluation of hydrofracture risk for HDD crossings, as well as methods for calculating pullback loads and pipe stresses during installation. The presentations were well received.
