On Wednesday 15th May 2019 Dr Devon Mothersille delivered a presentation at the ICE headquarters at One Great George Street, London on behalf of the British Geotechnical Association. The presentation was entitled ‘Ground Anchors: An Overview of Grouted Anchor Technology with Particular Reference to UK Practice’.
The event was well attended and was also streamed live so that interested members from the wider engineering community who were unable to attend could still access the information shared. The evening started with a tea/coffee reception in the ICE Brasserie followed by the lecture, a Q & A session and then a social gathering in the ICE Café bar sponsored by Geoserve Global Ltd.
The lecture briefly looked at the effects of the introduction of Eurocodes on the UK grouted anchor practice, clarified the essential features of maintenance inspections and service behaviour monitoring and described a case history where the world’s largest capacity cyclically loaded anchors where implemented to support overall stability in a concrete gravity dam.
Enjoy some photographs from the event.

Followers of this blog may recall that in December 2018, Dr Devon Mothersille visited Bauer (Egypt) at their offices in Cairo to negotiate a deal involving partnership between SBMA Ltd and Bauer (Egypt). We are delighted to announce that the deal is now secured and Bauer (Egypt) are exclusive licensees for SBMA technology in Egypt. Together with SBMA’s certified tendon manufacturer DECA SRL (based in Italy), we have big plans for the region and look forward to implementing the technology on projects in the very near future.

During meetings with Bauer UAE in Abu Dhabi and attendance at the DFI conference in Dubai, Dr Devon Mothersille took the opportunity to visit one of Bauer’s impressive construction sites. The project, commissioned by the Dubai Municipality, involved the development of a Deep Tunnel Stormwater System in Dubai’s Jebel Ali district. The deep tunnel stormwater system is intended to collect groundwater and stormwater runoff from an area of about 420 square kilometres and convey the captured flows to the sea. Bauer UAE was engaged by main contractor Archirodon Group N.V. and is responsible for the construction of the Main Terminal Pumping Station and Sea outfall which involves major diaphragm wall construction and ground anchor works.
The construction comprised two intersecting circular shafts of 64m and 45m diameter, 60m and 35m deep, respectively.

On the 24th and 25th April 2019 the Middle East Division of the Deep Foundation Institute held a conference that covered a variety of case histories and topics under the theme Geotechnical Engineering for Delivering Sustainable, Cost Effective Projects. The conference was hosted by the Roads and Transport Authority (RTA) at their headquarters in Dubai.
Forming part of a team with Bauer UAE’s Regional Geotechnical Design Manager, Mr Bora Okumusoglu, Dr Devon Mothersille delivered a presentation entitled ‘Implementation of High Capacity and Removable Ground Anchors for Support of Deep Excavation in the United Arab Emirates’. Mr Okumusolglu delivered a separate presentation entitled ‘Unsymmetrical Twin Shaft Retention System for Stormwater Terminal Pumping Station in Dubai’.
The conference also benefitted tremendously from a number of keynote lectures including one from Dr Mothersille’s research colleague from the University of Bradford (UK), Dr Abdussamie Mohammed Haimoni (Senior Manager at the RTA) who delivered the opening address.
This conference was enjoyable and highly informative and left the delegates in no doubt that the Middle East is embracing innovation, sustainability and a high standard of technical expertise in solving complex geotechnical problems.
Enjoy photographs taken from the conference.

CONSTRUCTORA LANCUYEN LTDA is a ground engineering contractor based in Chile. As part of an ongoing strategy Lancuyen have resolved to embrace new innovation and technologies in order to increase market share and allow them to undertake more challenging geotechnical engineering projects. Extensive liaison with Lancuyen’s Technical Manager Mr Rafael Martinez has culminated in agreement to implement SBMA technology within the region of Chile. SBMA Ltd’s Managing Director, Dr Devon Mothersille believes that this heralds an exciting era for both companies who share similar ambitions and vision. Preliminary SBMA tendon designs have already been completed for the substantial deep excavation support systems required for the Quilpué project in Chile.

On Friday 5th April 2019, Dr Devon Mothersille attended the Expert Witness Conference held at University of London Conference Central. The conference helped to expand knowledge and practical skills of expert witnesses instructed in commercial, construction, property and professional negligence claims. In addition, experts were given an opportunity to evaluate their roles and responsibilities during litigation and alternative dispute mechanisms and learn from leading practitioners who shared their knowledge and experience with enthusiasm and use of anecdotes, case studies and even role play.
The sessions were both enjoyable and highly informative and certainly helped to build on knowledge gained by Dr Mothersille when he successfully completed the programme; Legal Experience Training Advanced Professional Award in Expert Witness Evidence.

Building contractor Hill Partnerships Ltd have engaged the services of Dr Devon Mothersille (through his company Geoserve Global Ltd) to undertake a detailed integrity inspection and assessment of a canal wall near the Olympic Park in East London. The canal wall comprises sections of cantilevered sheet pile wall, anchored sheet pile wall (using deadman anchors) and a brick/masonry section; all of which have suffered various degrees of degradation. The complexity of the work has necessitated that Geoserve Global Ltd engage corrosion specialists Intertek (based in Manchester), structural engineers David Smith Associates (based in Northampton), geotechnical design engineers Remedy Geotechnics (based in Daventry) and canal boat specialists Safety Boats UK (based in Hertfordshire).
Hill Partnerships Ltd are constructing Phase 3 of the prestigious Fish Island residential development and the canal wall forms an important part of the project infrastructure. It is anticipated that the integrity assessment report will completed early May 2019 and Phase 3 of the residential development completed in 2021.

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.

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.
