In a bid to increase and improve their presence within the industry, both Dr Devon Mothersille and Coffey Geotechnics have initiated meetings that will develop firm links and strong future collaboration on geotechnical engineering projects worldwide. Where appropriate, as Managing Director of specialist ground anchor consultancies Geoserve Global Ltd, SBMA Ltd and AnchorTest Ltd, Dr Mothersille will join forces with Coffey Geotechnics in a way that is mutually beneficial to both parties. It is envisaged that this will involve collaboration on expert witness appointments as well as projects requiring geotechnical design and evaluation. In this regard very useful discussions were held with Coffey Principal Geotechnical Engineers Jane Belton and Erica Wilcox who will play important roles in future liaison
Senior Coffey Associates Dr Caesar Merrifield and Mr Eugene Gallagher were instrumental in arranging a special Master Class in grouted anchor technology which was delivered by Dr Mothersille at Coffey’s UK headquarters in Manchester. The audience, which comprised geologists, geotechnical engineers and members from Coffey’s senior management were exposed to extensive information on the current state-of-the-art, and this included descriptions on the status of standards and codes affecting UK practice as well as landmark case studies and strategies for maintenance and inspections of grouted anchor in service.

Design consultants ARCADIS have secured significant amounts of geotechnical design work related to the HS2 project and as part of an ongoing initiative to improve the knowledge and awareness of their design team, they invited Dr Mothersille to deliver a lunchtime presentation on SBMA technology. ARCADIS anticipate that multistage anchor technology could prove useful on forthcoming HS2 contracts where large retaining structures are proposed in cohesive soils.
The presentation lasts approximately 1 hour and a short Q & A session was allowed for at the end. The feedback was very positive and certainly indicated that considerable benefits were derived for those engineers that attended.

Following up on a special invitation Dr Mothersille visited the offices of world renowned civil engineering design consultants Dar Al-Handasah to deliver a ground anchor training seminar to key members of staff. Dr Mothersille was greeted by Professor Sherif Wissa (Director – Geotechnical & Heavy Civil Engineering Dept., Dar) and Dr Salwa Yassin (Senior Geotechnical Engineer, Dar).
The selected and well-informed audience compromised Ph.D graduates, structural and geotechnical design engineers and project managers. The seminar was well received and prompted a proactive Q & A session afterwards. The success of the training seminar heralds the start of an ongoing relationship where Dr Mothersille’s specialist consultancy services will be exploited by Dar Al-Handasah in the future.

At the headquarters of Bauer Dr Mothersille delivered a detailed presentation to Eng. Mohamed Mostafa (General Manager), Mr Ashraf Wahby (Executive Directory Member) and their team of Engineers. An enthusiastic Q & A session followed with associated discussions. This has set the platform for mutual corporation between SBMA Ltd and Bauer (Egypt) to implement various types of grouted anchor technology in the region.

Dr Devon Mothersille and Professor Stuart Littlejohn have published the second instalment of the Dam Anchoring Fundamentals feature in the magazine of the Deep Foundations Institute (November/December 2018 edition). This second part covers important aspects such as grouting, testing, monitoring and legacy anchors.
Following on from his published interview in the September 2018 edition of Ground Engineering magazine, Dr Devon Mothersille has published a Technical Note covering the new testing standard EN ISO 22477-5: 2018 with particular reference to UK practice.
It should be noted that Ground Engineering magazine have issued an apology for an error in the printing of the figures associated with this feature. The corrected version is available using the following link:
As the UK representative on the task group advising on the revision of Eurocode 7 – Anchors (TC 250/SC7/WG3/TG5), Dr Mothersille attended a series of meetings held over a period of two days at Villa Doria d’Angri in Naples, Italy. This beautiful and historic setting provided the ideal environment for extensive and detailed discussions covering a wide range of issues related to the second generation of Eurocode 7.
The meetings were very well attended with over 100 delegates from countries all over Europe.
Based on his own area of expertise, Dr Mothersille attended general sessions on anchors, on both days, and also actively participated in specially convened additional sessions aimed at tackling comments submitted by task group members on the redraft of EC7 – clause 8 (Anchors).

Dr Mothersille is a member of the Project Steering Group tasked to guide and advise the technical authors of the new CIRIA report RP 1061 entitled ‘Grouted anchors and soil nails condition appraisal and remedial treatment’. At a meeting held at the headquarters of Chartered Institution of Highways and Transportation in London, the group made substantial progress with the document, discussing report format, suitable case history content and numerous other technical issues. The report should be published in 2019.

As part of an ongoing initiative to improve knowledge and awareness of Eurocodes, British Standards Institution (BSI) organised a conference entitled ‘Eurocodes – Evolution and Ease of Use: How it will benefit you?’, hosted by the Institution of Structural Engineers at their headquarters in London. Dr Mothersille attended the event and benefited considerably from the information shared by a variety of speakers. These included the Chairman of Eurocode 7 Dr Andrew Bond who presented the latest improvements to Eurocode 7: Geotechnical design and BSI’s Director of Standards, Dr Scott Steedman who talked about Eurocodes and Brexit.
