Dr Mothersille appointed UK expert on Technical Committee for Geotechnical Monitoring – June 2021

On 25th June 2021, Dr Devon Mothersille attended his first meeting, via Microsoft TEAMS, of TC 182/WG2, the Technical Committee responsible for ISO 18674-8 (Geotechnical investigation and testing – Geotechnical monitoring by field instrumentation – Part 8: Measurement of forces: Load cells). Dr Mothersille has worked with load cells for over 35 years and will use this experience to provide positive input the excellent work already undertaken by the existing working group under the convenorship of Dr Walter Steiner (Senior Experte Geotechnik).  

Dr Mothersille visits the Eden Project and spots rock bolts! – May 2021

With the government’s systematic easing of lockdown restrictions many people are  visiting key tourist destinations within the UK. The Eden Project is an attraction in Cornwall, England, UK and has been on Dr Mothersille’s list of places to visit for many years. The project is located in a reclaimed china clay pit, located 5 km from the town of St Austell.

The complex is dominated by a series of huge enclosures consisting of adjoining domes, up to 55m high, that house thousands of plant species. The largest of the two domed structures simulates a rainforest environment (and is the largest indoor rainforest in the world) and the second, a Mediterranean environment. The attraction also has an outside botanical garden which is home to many plants and wildlife native to Cornwall and the UK in general.

The site required stabilization of the boundary quarry faces and tying down the foundation ring beam using double corrosion protected ground anchors. The stabilization of the quarry faces involved the installation of over 2,000 rock bolts and soil nails up to 11m long.

During a recent visit, Dr Mothersille spotted additional rock bolt installation works in the peripheral rock faces around the pit.

What started as a fascinating trip to photograph an extraordinary collection of plant life ended with an interesting view of active rock bolt installation works!

Dr Mothersille presents to the Yorkshire Geotechnical Group – April 2021

Representatives from the Institution of Civil Engineers Yorkshire and Humber division invited Dr Mothersille to deliver a presentation on grouted anchors to the Yorkshire Geotechnical Group. Following months of negotiations and planning, due to competing existing commitments, the talk finally took place on 13th April 2021 and was successfully delivered to a virtual audience.

Dr Mothersille presents to a large virtual audience in India – Mar 2021

Through a valued collaboration with the USA division of the Deep Foundations Institute (DFI), DFI India has organised a series of webinars developed for students in civil engineering with particular interests in geotechnical engineering; the initiative is DFI India Student Outreach Program ‘Groundwork’. 

Following an invitation by DFI (USA), on 16th March 2021 Dr Mothersille delivered a 40-minute lecture on ground anchors followed by a 10 minute Q & A session. The talk covered definitions/terminology, exploring the concept, worldwide applications, design, corrosion & corrosion protection, construction and testing (including the innovative AnchorTestTM technology for data processing and analysis). Finally, Dr Mothersille presented a case history detailing the raising of Hazelmere dam in South Africa. This example usefully demonstrated many of the aspects covered in the webinar on a unique project.

The session included an excellent 20-minute presentation from Ms Jewels Stover (Nicholson Construction) entitled ‘The Art of Negotiation’.  The attendees included students, academics and practising engineers from all over India who would have certainly  derived considerable benefits from these two subject areas.

Special thanks are due to Ms Mary Ellen Large (Director of Technical Activities, DFI, USA) for recommending Dr Mothersille to be a speaker at the event, Mr T Rambabu (UR Ground Engineering Pvt Ltd) for acting as session moderator,  and Mr Pranav Jha (Assistant Manager, Operations, DFI India) for coordinating the IT aspects on the day.

Dr. Devon Mothersille presents to members of the Nigerian Society of Engineers – Jan 2021

Towards the end of 2020 the Nigerian Society of Engineers (NSE), UK branch invited Dr Mothersille to deliver a presentation to its membership covering his area of expertise.  In January 2021, Dr Mothersille gave a presentation entitled ‘An Introduction to Ground Anchor Technology’. The presentation’s objective was to provide the audience with an insight into ground (grouted) anchor technology, initially defining terms and exploring the concept and then showing a variety of applications by drawing on examples from a worldwide database. After briefly covering some basic implementation features, a case study was described that captured several world firsts concerning ground anchor usage. By the end of the session, there was no doubt attendees gained an improved fundamental understanding of how ground anchors are applied, designed, constructed and tested.

The event was declared a resounding success by the President of the NSE, Dr. Sunday Popoola. The audience’s enthusiasm was proved by the fact that the Q & A session, convened afterwards, lasted longer than the 50-minute presentation itself!

Grouted anchor book deal established with Taylor & Francis Group – Nov 2020

It has been years in the making, but finally, a book deal is agreed with internationally renowned publisher Taylor & Francis Group. The textbook,  scheduled for completion in summer 2023, is entitled ‘Grouted Soil and Rock Anchors’.

The book is aimed at consulting engineers, contractors; civil, structural and geotechnical engineering students and even asset owners,  who during their activities, propose or encounter the use of grouted anchors. These geotechnical installations have been used worldwide to support various types of structure. Over time, millions of grouted anchors have been installed successfully ranging from systems of a few tonnes capacity in small retaining walls to pre-stressed tendons of several thousand tonnes capacity to resist direct tension, sliding, overturning and dynamic loading in dams.   Other applications include stabilising deep excavations, bridge abutments and several different forms of geotechnical structure. 

Anchors have established a permanent place in construction practice, but for engineers and asset owners not yet thoroughly familiar with modern anchoring technology, conventional and potential applications will be outlined to provide some perspective and encourage further exploitation.

The book is structured around the key areas of design, construction, testing and service behaviour performance. In addition,  maintenance inspection, condition assessment, innovative applications and current research will be addressed. In recent years standards and codes of practice have undergone significant changes, particularly in Europe, and these essential developments will also be covered.

Dr Devon Mothersille is the lead author with highly respected co-authors Dr Donald Bruce (USA) and Professor Stuart Littlejohn (UK). The authors have collectively compiled over 120 years of experience and published hundreds of technical papers and articles covering various aspects of geotechnical engineering with particular reference to ground anchoring practice. Their collective expertise has been developed from direct input into projects all over the world, academic and industrial research, and dedicated participation in various committees associated with the development of standards, codes of practice and best practice guidance documents.

Dr Mothersille presents at the CIRIA Report C794 launch event! – November 2020

November 2020 has seen the publication of the new CIRIA report C794 entitled ‘Grouted anchors and soil nails: inspection, condition assessment and remediation’. This unique document fills a gap in the current literature, where there is limited guidance on this highly specialised area. It will undoubtedly assist asset owners, designers, contractors and others involved in the condition assessment, planning and execution of the works, including monitoring, maintenance,   remediation, repair and replacement of grouted anchors and soil nail structures.  

The drafting of C794 was a team effort. CIRIA awarded the contract for the work to the geotechnical engineering consultancy Gavin & Doherty Geosolutions Ltd (GDG). Following reviews from a project steering group, comprising some 20 individuals, GDG engaged the services of Mr Chris Irvin (Dywidag, UK) and Dr Devon Mothersille (Geoserve Global Ltd and  Single Bore Multiple Anchor Ltd) for specialist input as technical authors.

The Covid-19 pandemic demanded that the launch event for C794 took place online, and this was judged successful with some 85 participants attending. The technical authors delivered four presentations covering the following:

  • Introduction and background
  • Grouted anchors: Condition assessment and remediation
  • Grouted anchors: monitoring and maintenance
  • Soil nails and soil nail structures

The presentations were followed by a question and answer session that allowed members of the audience to clarify points of interest and gain more detail on specific areas.
