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.
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.
Bennett Trenchless is pleased to announce that we will be presenting three papers at NASTT’s annual No-Dig conference on March 20-24, 2016 in Fort Worth, Texas at the Gaylord Texan Convention Center. On the afternoon of March 21, we will present paper MA-T4-01 which discusses a challenging 108-inch pipe ram project on the Northern California Coast. Paper TM1-T2-02 will be presented the following morning which will describe an HDD installation of twin inverted siphons as part of the larger Trinity River Vision project for the City of Fort Worth. BTE will also present paper WM-T1-02 on the morning of March 23 which discusses the design and construction of 1,200-feet of 36-inch gas pipeline under a major Interstate using HDD.
In addition to the technical papers being presented during the conference, BTE staff will also be serve as volunteer instructors on NASTT training courses before and after the conference. On the morning of Sunday, March 20, BTE staff will serve as instructors for NASTT’s Trenchless Technology Short Course – New Construction. After the conference concludes on Wednesday, March 23 and Thursday March 24, BTE staff will serve as instructors for both NASTT’s HDD Good Practices Guidelines Course, and NASTT’s Pipe Bursting Good Practices Course.
On November 18, 2015, Matthew Wallin will serve as a volunteer instructor for the Northwest Chapter of the North American Society for Trenchless Technology. Mr. Wallin will be teaching NASTT’s Trenchless Technology Short Course – New Construction. The course is being offered in conjunction with the Northwest Trenchless Conference which is occurring on the following day, November 19.
On November 5, 2015, David Bennett will serve as a volunteer instructor for the Rocky Mountain Chapter of the North American Society for Trenchless Technology. Dr. Bennett will be teaching NASTT’s Trenchless Technology Short Course – New Construction with Dr. Sam Ariaratnam. The course is being offered in conjunction with the Annual Regional No-Dig Conference which is occurring on the previous day, November 4.
Bennett Trenchless Engineers will be attending the North American Society for Trenchless Technology’s annual No-Dig conference in Denver from March 15 – 19. Matthew Wallin will be teaching the New Installations 101 course with Dr. Sam Ariaratnam and Collins Orton on Sunday March 15. David Bennett, Matthew Wallin, and Mary Neher will be teaching the Horizontal Directional Drilling Good Practices Course on Wednesday, March 18 and Thursday, March 19. David Bennett will also be assisting with teaching the Pipe Bursting Good Practices Course on March 18-19.
David Bennett taught at the inaugural HDD Academy in Tempe, Arizona on February 19-20. Dr. Bennett spoke on geotechnical investigations and design calculations with regard to HDD installations.
Mary Neher and David Bennett presented to the ASCE Oregon Section Geotechnical Group on October 24, 2014. Dr. Bennett discussed geotechnical investigations and settlement analysis for trenchless construction projects. Ms. Neher discussed calculation of hydrofracture risk and pullback and pipe stress for HDD installations.
