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.
Outstanding Geotechnical Engineer and Researcher, Dr Antonio Marinucci will act as marketing agent for the AnchorTest software package (configured for iPads; www.anchortest.info) and SBMA technology in the US and Canada. Dr Marinucci is also a recently inducted member of the Geo-Trust network.

Some of the geotechnical engineering specialists, forming part of the Geo-Trust collective, took advantage of their attendance at the 5th international grouting conference to convene a group meeting. The group discussed current workloads, interesting developments and future collaborations.

Dr Devon Mothersille presented a paper entitled ‘Overcoming the challenges of grouting ultra-high capacity anchors dam in jointed quarzitic sandstone’ at the 5th International Grouting Conference, held between 9th-12th July 2017 in beautiful Honolulu, Hawaii. Over a four day period the well-attended conference provided three keynote lectures and technical sessions covering a broad spectrum of subjects including grouting case histories, drilling/grouting and deep mixing/ diaphragm walls.

Following a special invitation from Ingerop’s senior management, Dr Devon Mothersille delivered a presentation to Directors from Ingerop (France), Ingerop (South Africa) and Geos (a subsidiary of Ingerop France).
This initiative was designed to further strengthen relationships and explore new markets for consultancy services with respect to ground anchor applications worldwide.
Several exciting possibilities were discussed included the delivery of major projects in Kenya, Democratic Republic of Congo and Mozambique.

The work of the committee ISO/TC 182/WG3 continues with the successful evaluation of 171 comments on the draft European standard for the testing of grouted anchors ISO DIS 22477-5. In all some 325 comments were evaluated over two separate 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 over the coming months.

Dr Devon Mothersille delivered a lecture entitled ‘An Introduction to High Capacity Anchors in Soils and Weak Rocks’ to the 38th Annual Short Course: Grouting Fundamentals & Current Practice, held at the University of Texas in Austin.
This forms part of an annual commitment to the short course and Dr Mothersille was honoured to share the stage with a host of high calibre international grouting experts. The subject matter was varied, covering many aspects of grouting technology, methods and applications in a variety of geological conditions.
