About theanchormanblog

Having spent two decades working closely with Tony, Dr. Devon Mothersille provides the continuity of cutting edge technical expertise and excellence within SBMA Ltd. Dr Mothersille received his undergraduate degree in Civil and Structural Engineering at the University of Bradford, UK where he also completed a Ph.D. for his work on the influence of close proximity blasting on ground anchor systems in rock. He entered the construction industry, working for both civil engineering consultants and contractors, in 1989 and subsequently became the Managing Director of two specialist ground anchor consultancy practices: Geoserve Global Ltd and Single Bore Multiple Anchor Ltd. He has worked as a ground anchor consultant in many parts of the world including Spain, Australia, the USA, Russia and the Middle East where he advised clients on complex ground anchoring projects. These include the prestigious Diagonal Mar Development in Barcelona, the Burnley Tunnel Project in Melbourne Australia, the Wadi Abdun Bridge Project in Amman Jordan and the Aviva Stadium project in Dublin, Ireland. He was deputy chairman of the International Ground Anchor Conference held in London in 2007, and currently acts as an expert witness/adviser on legal cases as well as being an active member of two committees charged with the implementation of the new Eurocodes covering the design, construction and testing of ground anchors and soil nails.

New publication in DFI Magazine – September 2018

Dr Devon Mothersille and Professor Stuart Littlejohn have jointly published Part 1 of an article entitled ‘Dam Anchoring Fundamentals’ in the Deep Foundations Institute (DFI) magazine – September/October 2018 edition. The first of a two part article covers some essential aspects of anchor design, tendon fabrication, borehole drilling and tendon installation with particular reference to dams. The second, and concluding part, of the article will be published over the coming months in the next edition of the DFI magazine.

Dr Mothersille interviewed by Ground Engineering magazine – August 2018

In his capacity as Convenor of the technical committee TC 182 – Working Group 3 (EN ISO 22477-5: 2018 – Testing of Grouted Anchors), Dr Devon Mothersille was interviewed by the editor of Ground Engineering magazine Claire Smith as a precursor to the imminent publication of the new standard. The long awaited standard has been under development for over fourteen years and, according to British Standards Institution, is scheduled for publication in late August 2018.  Since Dr Mothersille’s appointment as Convenor in April 2015, it has been a tremendous achievement to have taken the document to completion over an intensive three year period.

The standard is complicated by the fact that it features three types of test (Investigation, Suitability and Acceptance tests) and within each test type, there are three test methods (Test Methods 1, 2 and 3). The main challenge was gaining consensus from European member countries that have established traditional approaches. Over the last three years several meetings were held in various locations across Europe including London, Munich, Lisbon  and Belgium, and over 1000 submitted comments were addressed in order to create content that satisfied all parties. Despite the complexity of the standard, it will provide a unified approach to testing across Europe and will form a trinity with two other related standards; EN 1997-1:2004+A1:2013 (Design) and EN 1537: 2013 (Execution).

A summary of the interview can be found on page 7 of the August/September edition of Ground Engineering magazine.

 

 

Landmark deal established between Bauer International FZE and SBMA Ltd – JULY 2018

Months of negotiations have culminated in a landmark deal between Bauer’s Middle East division (Bauer International FZE) and UK based Single Bore Multiple Anchor Ltd. The two companies will partner as business associates to implement specialized ground anchor technology in the Middle East and Iran.

During a visit to Bauer’s Abu Dhabi office earlier this year, SBMA Ltd’s Managing Director Dr Mothersille was left in no doubt that the association between Bauer and SBMA Ltd would be a good fit, since both companies shared a similar vision for expanding the use of anchoring in the region, delivering excellence to their clients and further developing the technology through continued research and development.

Already projects are earmarked, and this heralds an exciting period for the use of ground anchors in a variety of diverse applications.

Look out for further postings in the near future.

Meeting of TC 250/SC7/WG3/Task Group 5 (Anchors) – Brussels 18th/19th June 2018

Over a demanding two-day period, members of TC 250/SC7/WG3/Task Group 5 met at the offices of the Belgian Building Research Institute in Lozenberg, Brussles to discuss aspects related to the most recent draft of the revised Eurocode 7, Chapter 8 on anchors.

Dr Mothersille presents at the International DFI conference in Rome – June 2018

On behalf of specialist ground engineering contractor Kasktas, A.S (Turkey), Dr Devon Mothersille presented a technical paper entitled:

DESIGN, CONSTRUCTION AND PERFORMANCE OF SINGLE BORE MULTIPLE ANCHORED DIAPHGRAM WALL IN IZMIR, TURKEY’ at the DFI-EFFC International Conference on Deep Foundations and Ground Improvement Urbanization and Infrastructure Development – Future Challenges. This conference was held in the beautiful city of Rome between 5-8thJune 2018.

The technical paper was co-authored by Dr Rasin Duzceer (General Manager, Kasktas, A.S), Mr Alp Gokalp (Deputy General Manager, Kasktas, A.S) and Mr Senol Adatape (Senior Design Manager, Kasktas, A.S) and documented the successful construction of some 2400 SBMAs, with working loads up to 670kN for excavation support as part of the prestigious Mahall Bomonti Development in Izmir, Turkey. The SBMAs achieved the highest test loads of any anchor system installed in the region and has paved the way for many more substantial projects in the future.

In addition excellent preliminary discussions were held between Dr Mothersille, Dr Rasin Duzceer, Mr Rajeev Narayan Dwivedi (Director, Chennai Metro Rail Limited, India) and Mr Mohan Ramanathan (Managing Director, Advanced Construction Technologies, India) re the use of SBMA technology in India.

Dr Mothersille visits business associates in Turkey: Anchor works for the Mahall Bomonti development in Izmir, Turkey complete – March 2018

Specialist foundation contractor Kasktas AS have successfully implemented SBMA technology on three deep excavations that will form an essential part of the prestigious Mahall Bomonti development in Izmir, Turkey. In total some 1900No. SBMAs were constructed in problematic alluvial soils and under a high water table. When complete the superstructure will be 245m high and will be the tallest building in Izmir and the third tallest in Turkey.

The successful execution of this project maintains the high standards produced by Kasktas AS throughout their association with SBMA Ltd and this will prove highly beneficial to clients within the region for future projects.

Details of the performance of the anchored structures are featured in a technical paper that has been accepted and will be presented at the DFI conference in Rome (June  2018).
