Belated publication from CIRIA – July 2017

Back in December 2012 Dr Devon Mothersille presented a paper to an audience at the headquarters of the Construction Industry Research and Information Association (CIRIA) in London. Interestingly, the paper, entitled, ‘Aged ground anchors and soil nails’ has only recently been published by CIRIA in the proceedings of the fifth conference on ‘Geotechnical Issues in Construction’ held on 3rd December 2012.

Amongst other things, the paper identifies the ground conditions that accentuate corrosion risk and uses case history evidence to illustrate severe corrosive degradation in anchor and soil nail heads.

Working Group meeting for committee ISO/TC 182 held over two day in Lisbon, Portugal – May 2017

The work of the committee ISO/TC 182/WG3 continues with the successful evaluation of 171 comments on the European standard for the testing of grouted anchors EN ISO 22477-5. In all some 325 comments were evaluated over two meetings, the first of which took place in London in early April 2017. The task of seeking resolution to the 325 comments was further complicated by the fact that there are three test types and three test methods associated with the test types. In addition, there are several member countries that adopt variations to the different test methods.  Despite this, there is no question that the meetings in both London and, more recently, in Lisbon where successful.

On the basis of the evaluation of comments, the document will be amended and resubmitted to the Working Group for further assessment.

Team BMW commissioned by CEATI to undertake complex anchor study – May 2017

A dream team comprising Dr Donald Bruce, Dr Devon Mothersille and Mr John Wolfhope (BMW) have been engaged by The Centre for Energy Advancement through Technological Innovation (CEATI) to undertake a study of world dam anchor practice in a bid to produce a Best Practice Guidance for North American dams. CEATI based in Montreal, Canada are an influential body with a specific remit to improve technology that can facilitate further development and maintenance of dams which form an essential component in national energy enhancing infrastructure.

Dr Donald Bruce (Geosystems), Dr Devon Mothersille and Mr John Wolfhope (Freese & Nichols) recent met in Austin, Texas  to develop forward strategies for the effective delivery of the project. This successful meeting has confirmed that many months of hard work lie ahead but this will undoubtedly result in a landmark study that will tremendously benefit the dam anchor industry.

Anchor technology seminar delivered to Lancuyen representative – May 2017

Senior Geotechnical design engineer from Chilean Foundation contractor Lancuyen, Mr Rafael Martinez, attended a specially organised two day ‘one-on-one’ seminar with Dr Devon Mothersille. This unusual initiative was requested by Lancuyen in order to accelerate their knowledge in ground anchor technology. During the intense two-day interactive knowledge sharing session, case histories were described which covered aspects of design, construction, testing and monitoring of ground anchors. New technologies such as AnchorTest were discussed and demonstrated together with detailed descriptions and evaluation of the Single Bore Multiple Anchor system. Lancuyen are currently considering the use of the SBMA system for a major slope stabilisation project in Chile and this was also discussed in detail.
