Senior Geotechnical design engineer from Chilean Foundation contractor Lancuyen, Mr Rafael Martinez, attended a specially organised two day ‘one-on-one’ seminar with Dr Devon Mothersille. This unusual initiative was requested by Lancuyen in order to accelerate their knowledge in ground anchor technology. During the intense two-day interactive knowledge sharing session, case histories were described which covered aspects of design, construction, testing and monitoring of ground anchors. New technologies such as AnchorTest were discussed and demonstrated together with detailed descriptions and evaluation of the Single Bore Multiple Anchor system. Lancuyen are currently considering the use of the SBMA system for a major slope stabilisation project in Chile and this was also discussed in detail.

Following the award of the contract to provide consultancy services and removable anchor technology on the Corniche Tower project in Abu Dhabi, preparations are underway for a series of anchor trials scheduled for June 2017. SBMA Ltd will use the services of experienced driller/grouter/anchor installer Mr David Hayes to supervise the initial tendon manufacture and installations for the trial anchors. The tendon components were provided by DECA s.r.l (www.decanet.it) and additional consultancy support by Geoserve Global Ltd (www.geoserve global.com).

Outstanding engineering consultant Ingerop South Africa (ISA) has purchased a licence to use the innovative software package AnchorTestTM (www.anchortest.info). ISA (www.ingerop.co.za) has an increasing portfolio of projects within, and outside South Africa, and will use the software package to enhance their design and site supervision capabilities on projects that utilise ground anchor technology.
Dr Devon Mothersille attended technical meetings and visited SBMA’s certified anchor tendon manufacturer DECA s.r.l. in Genoa, Italy. Over the years DECA has provided a high quality, reliable and professional service in providing geotechnical hardware on SBMA projects worldwide.
They have now expanded their portfolio beyond the supply of removable SBMA tendons to tendons for permanent anchor systems and monobar systems for both anchors and soil nails. Substantial technical improvements have been implemented which allow DECA to deliver their high quality products in relatively short timescales.
Further to successful technical meetings DECA have agreed to act as agents for sale of the new innovative AnchorTest software licence which was developed, and is supported, by AnchorTest Ltd.

SBMA Ltd has successfully secured the contract to provide the technology and consultancy support for the removable anchor systems that will be used for part of the temporary foundation support scheme at the Corniche Tower project site in Abu Dhabi. The anchors will support diaphragm and secant pile walls that will form a 4-basement excavation. The construction of multi-storey residential buildings will commence after the completion of the basement systems.

As Chairman of Working Group 3 (part of the Technical Committee 182), Dr Devon Mothersille convened a meeting of pan European anchor experts to evaluate some 325 comments received on prEN ISO 22477-5 (Geotechnical investigation and testing – Testing of geotechnical structures – Part 5: Testing of grouted anchors). Over a two day period 12 attendees evaluated the comments and scrutinised the draft document, clause by clause. During a very productive and highly technical session considerable progress was made and this was due to the wealth of experience and technical expertise provided by the working group members.
The lunches for the delegates were sponsored by Single Bore Multiple Anchor Limited and the evening meal was sponsored by Dywidag Systems International. Many thanks are also due to Ms Jennifer Harris for her contributions with the administration and real-time editing and collating of information during the discussions.

Synergy, collaboration, teamwork and cooperation were just some of the words used during discussions between Dr Mothersille and Ingerop’s CEO Mr Neel Daya. It is anticipated that this successful alliance will strengthen for many years to come and will extend beyond the borders of Southern Africa.
