Dr Mothersille visits Bauer’s Global Gateway Development project in Abu Dhabi – October 2018

Following the successful delivery of the seminars in Dubai and Abu Dhabi, Dr Mothersille visited Bauer’s Global Gateway residential development construction site in Abu Dhabi.

The project involves an excavation supported by secant pile walls which are themselves stabilized by an anchored pile cap. Importantly all the anchors on the project (166No.) are removable SBMAs with working loads of 800kN and overall lengths of 18.5m. In order to demonstrate removability of the prestressing strand, the client’s representative was invited to witness the removal process.

Three lengths of prestressing strand were successfully removed using a monojack initially and then with an excavator paying due regard to safety during the whole operation.

Dr Mothersille delivers special half-day seminar in Abu Dhabi – October 2018

Following the recently established license agreement with Bauer International FZE, SBMA Ltd/Geoserve Global Ltd’s Managing Director Dr Devon Mothersille was the invited speaker at a specially arranged half-day seminar held at the Al Maha Arjaan by Rotana hotel in Abu Dhabi on 10th October 2018.

The first part of the seminar covered many aspects of ground anchor technology with particular reference to systems specifically designed to generate high capacities in soils and weak rocks. This part also included sections on the current status of Eurocodes with respect to anchors, new innovations and recent developments. In the second part Dr Mothersille presented several examples of international ground anchor applications and then described two pivotal case histories that demonstrated a number of world firsts.

The audience included engineers and municipality representatives who engaged in  useful Q & A sessions during and at the end of the seminar.

Dr Mothersille wishes to thank Mr Farid Mansour (Regional Technical Manager, Bauer) and Mr Bora Okumusoglu (Regional Design Manager, Bauer) who joined him and delivered short presentations covering the history of Bauer and local projects incorporating anchored excavation support.

New anchor testing standard published – September 2018

On 27th September 2018 British Standards Institution announced that the long awaited grouted anchor testing standard, BS EN ISO 22477-5: 2018 has been published. Dr Devon Mothersille was nominated to take over the convenorship of the European working group (CEN/TC 182/WG5) charged with the task of completing the development of the document in 2015. By way of background the draft version of this standard has been in existence for over a decade, so it was a tremendous achievement to complete the document over a two and a half year period.

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.
