Dr Devon Mothersille presents at the 40th International Grouting Fundamentals Course – Austin, Texas – March 2019

The 40th International Grouting Fundamentals course was held at the Engineering Education and Research Centre at the University of Texas. Dr Mothersille shared the stage with established grouting experts including the world-renowned Mr Jim Warner who is still actively lecturing at 87 years old! In addition, to covering the theory and application of grouted anchor systems in soils and weak rocks, Dr Mothersille also presented the key features of AnchorTest, the innovative real-time data management software that has massively optimised the mandatory anchor testing process.

Special thanks are due to Dr Donald Bruce who donated 10 minutes of this own talk time to allow Dr Mothersille to deliver a more effective presentation with a substantial case study.

Eurocode 7 task group enjoy a productive meeting in Brussels – Feb/Mar 2019

As the UK representative on committee TC 250/WG3/TG5: Anchors, Dr Devon Mothersille attended a two day meeting with nine other European colleagues in Brussels. The meeting was hosted by Convener Mr Noel Huybrechts at the headquarters of Belgian Building Research Institute.

The clauses related to anchor design within Eurocode 7 (EC7) are currently undergoing the obligatory 5 year review. Even at this relatively early stage in the process special congratulations should be given to the efforts of EC7-3, Project Team 5 member, Mr Klaus Dietz, for his analysis and descriptions of the various approaches to anchored structure design adopted across Europe.

The meeting was both intense and demanding but resulted in positive consensus on a number of issues and this should serve to create an improved document.

Collaboration to be established with Coffey Geotechnics – Feb 2019

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 updates on the status of standards and codes affecting UK practice as well as descriptions of landmark case studies and strategies for maintenance and inspections of grouted anchors in service.

Dr Mothersille visits Design Consultants ARCADIS in Birmingham, UK – Jan 2019

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 lasted 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.

Dr Mothersille delivers anchor training seminar to consultants Dar Al-Handasah at their headquarters in Cairo, Egypt – December 2018

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.

Dr & Mrs Mothersille visit Bauer in Cairo, Egypt – December 2018

Dr Mothersille, accompanied by his wife, visit the offices of contractor Bauer, Egypt S.A.E in Cairo.

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.
