AGS WORKING GROUP UPDATE: BUSINESS PRACTICE The latest update from Group Leader Sally Hudson.
Chair’s Foreword I am writing this Foreword sitting at my dining table with my youngest son sitting opposite me ‘at school’ completing and listening to his lessons on-line, my eldest son is still in bed ‘on University time’ and my wife is on rota as she is a ‘Key Worker’. These situations are being repeated in households across the UK and it really is surreal times. As many workers have now been furloughed or are working from home, many AGS members are asking what should be the approach for site works and those construction sites which are still expecting subcontractors and workers to turn up. Many companies are announcing full scale shut down of services, others are moving to on-line services and others are still announcing business as usual so it is a very confusing picture. So what is the advice of the AGS to its members? We have already passed on guidance which has been provided by the Construction Industry Council (CIC) via Ground Forum, a brief look at this can be found in the News in Short. The CIC have direct contact with government departments and so this advice should reflect the most up to date guidance from the government and it seems to be taking a sensible approach. However, as much of current policy is being created off the hoof there is often a lack of detail which leads to confusion and different interpretations. There are also a number of buzz words which are being floated around and again these often have unclear definitions. Therefore, the advice is that members should approach the Coronavirus risk as they

would any other hazard. Members should be creating safe systems of work and taking a risk based approach to their work. Sites and projects should be assessed to determine if they really are safety critical? If the work was delayed for three or six months what would the consequences be? Members should assess the personal circumstances of their employees and encourage those with vulnerable household members or circumstances to not attend work. Sites which are deemed to be safety critical must implement the social distancing and enhanced personal and site hygiene controls. The most important point is that the highest form of risk control is to eliminate the risk which means that many sites should be made safe and secure to allow site workers to return home and observe the enhanced social distancing protocols currently in place. So please stay safe, risk assess your projects and keep your personnel safe. We are always on the lookout for additional, informative content for the magazine, so if you have a case study or technical article that you think the wider geotechnical and geoenvironmental public would find beneficial, please do get in touch. We would be interested in your feedback on the magazine and our future plans. Please contact ags@ags.org.uk if you have any comments.

A Candid Look at Responses to SiLC Membership Questionnaire 2019
COVER STORY PAGE 6 Stuart Wagstaff of Soil Consultants examines and draws comparisons between various sampling methods.
A previous questionnaire was issued to the membership in 2009. As part of the SiLC Marketing Action Plan (2018 to 2021), it was proposed that a revised and updated questionnaire would be issued to the membership and this was done in 2019. This article looks to examine the responses to the questionnaire.

News in Short Update from the AGS regarding COVID-19 With the ongoing situation of COVID-19, the AGS would like to remind members of the current guidance. Businesses and workplaces should encourage their employees to work at home, wherever possible; if someone becomes unwell in the workplace with a new, continuous cough or a high temperature, they should be sent home and advised to follow the advice to stay at home for 14 days and employees should be reminded to wash their hands for 20 seconds more frequently. The AGS are continually reviewing the situation and the decision has been made to postpone both the AGS Annual Conference which was due to take place on 2nd April and the Laboratories, Instrumentation and Monitoring Conference which was due to take place on 15th July. Further details about both conferences will be released in due course. Currently, the AGS are looking to go ahead with
the AGS Data Management Conference on 23rd September, however this will be monitored closely. For those who attend AGS Working Group meetings, we will be using remote and conferencing technologies to hold these meetings until further notice and details of these will be circulated with the meeting notification as usual. The AGS Secretariat are currently working remotely, but we are checking our voicemail twice daily and aim to get back to you as soon as we can. We can also be contacted by email via ags@ags.org.uk.
Online Geotechnical Courses Offered Reacting to the changing landscape of the world amid the COVID-19 pandemic, geotechnical training experts Equipe Training Ltd have announced that they will be offering a wide suite of training as online courses. “The courses will still be live and trainerled, but will use a digital platform to engage

Urgent PPE Support for the NHS The Construction Industry Council has been in touch with NHS London Hospitals Trust . The Trust has sent sent out a list of PPE requirements to ask what might be available from the construction industry across the spectrum of equipment required. A summary of the equipment required is as follows: • FFP3 Respirator Masks • Full Face Visors (disposable)
• Full Face Visors (reusable) • Safety Goggles/Glasses • Hand Sanitiser • Full Body (Hazardous Material) Suits • Logistics/Transport support It would be much appreciated if all readers of the AGS Magazine could cascade the request throughout their networks and see what might be available. If you are able to assist in the provision of any of these items, whether for the London area or outside of this, please contact ags@ags.org.uk who will pass your details on to the centralised contact.

COVID-19 - What is critical construction work?
•
The Construction Industry Council has asked its Member CEOs, Board, Public Affairs Group, CIC Champions, CIC Nation and Regional Chairs, Housing Panel, Health and Safety Committee and Associate Members to draw up a list of works deemed critical in order to assess which should continue during the COVID-19 shutdown.
The full, exhaustive list of ‘critical’ works can be found within a blog post from CIC Chief Executive, Graham Watts here.
AGS representatives have been party to these discussions and the CIC have advised that works should not continue unless they fall under one or more of the following related critical categories: • All general building control work for nationally important buildings / facilities, e.g. NHS estate, GPs, etc. • Structural inspections for subsidence / movement to determine risk
• •
Maintaining key national infrastructure: power stations and grid, motorways, railways, utilities etc. Works pertaining to nuclear projects Vital infrastructure development projects
If construction sites remain open (and the argument posed by CIC is that they should only remain open if the work is critical) then construction work should only continue if: • it can be carried out under the guidance issued by Public Health England; • it can be undertaken without compromising safety and health; • it is carried out in accordance with the Site Operating Procedure published by CIC http://www.constructionleadershipcouncil. co.uk/news/site-operating-proceduresduring-covid-19/; and workers can travel safely and responsibly to sites.

Graph 1 shows the culmination of nearly 1,200 data points and whilst the number of points make the graph difficult to read, Graph 2 presents the envelopes of each of the data sets [lower and upper bound limits representing approximately 90% -95% of the data points ignoring anomalous low and high values]. On these graphs is also plotted ‘an average line’
which has been derived through simple visual assessment of the data set [based on the lines produced by four engineers assessing the data independently]. Whilst this is not technically a scientific average, we believe this is representative of ‘the designer’s’ approach. Graph 3 further simplifies the data by plotting the middle average of the envelopes and also includes the ‘average’ line from all data as a visual benchmark which, is continued through all graphs. Graph 4 compares these data sets with the shear strength profiles for London Clay presented by Patel [1992] on 100mm diameter specimens. Although this is not an exhaustive analysis, on face value, the following points are noted: •

Uncorrected SPT-derived Cu shows the narrowest envelope of all the data sets. Correcting the N value for energy efficiency, serves to further narrow this envelope Whilst samples derived in plastic U100 sampler tubes gave a similar scatter in results to other ‘undisturbed’ measurement techniques, the overall strengths measured were greater, giving a higher average

Design engineers, in our experience, continue to try and oversimplify this formation but, the London Clay is a variable deposit and the ground is not ‘Just London Clay’ as we hear on so many occasions. Thus, investigation designers should be advocating a sensible level of investigation to provide a reliable and representative data set. Whilst there is a wealth of information in the literature on the London Clay, on reflection, do we as an industry still need to put further research into sampling and testing techniques to provide the necessary confidence that routine ground investigation can provide reliable design parameters in light of the Eurocodes?

values. In saying this, quality of ‘workmanship’ is a considerable factor and investigation companies should ensure drilling operatives are suitably experienced and supervised along with ensuring equipment is well maintained and sampling tubes are clean. The divergence of measured Cu profiles is proof that differences do exist in the London Clay and indeed, in our experience, the strength profiles around London do vary considerably, with some areas showing significantly weaker profiles than others; this should be accepted by the industry who should not be so quick to criticise the investigation contractor.

SiLC Annual Forum 2020 held at the Geological Society
A Candid Look at Responses to SiLC Membership Questionnaire 2019 A previous questionnaire was issued to the membership in 2009. As part of the SiLC Marketing Action Plan (2018 to 2021), it was proposed that a revised and updated questionnaire would be issued to the membership and this was done in 2019. Some questions remained the same as in the 2009 questionnaire, but the majority were revised,

for example to include questions relating to the NQMS and the role of an SQP. The response to the 2019 questionnaire was 46% of registered SiLCs (90 responses), whereas in 2009 it was 43% (57 responses). In general, those SiLCs who responded to the 2019 questionnaire consider that achieving SiLC registration had been worthwhile and
need of increased visibility in the industry to demonstrate why it is needed and why people should want to attain it. One response was even stronger saying it costs a lot of money and is of limited value. On the other hand it can be seen as encouraging in response to one of the other questions that there has been some requirement for SiLCs in pre-qualifications or specific project work. This applies to a range of groups across the industry, particularly Regulatory Authorities where 47 respondents out of the total of 90 indicated a requirement, but perhaps disappointing that only 28 respondents indicated a requirement from Environmental Consultants. The responses to the question regarding how well-known is SiLC, indicate that a strong marketing effort is needed in order to increase the awareness of all groups other than Environmental Consultants and Regulatory Authorities and, even for these, some marketing effort would be beneficial. Suggestions of where marketing is needed were Scotland, legal advisers, insurers, private developers, large landowners, NHBC and noncontaminated land professionals.

... proactive management is essential in order to minimise the levels of stress in the workplace.
The key to minimising stress in the workplace, therefore, is to ensure that the managerial controls in place emphasise a balance between the requirements of the job (demands and pressures) placed on the individual with the individual’s capability (skills and knowledge) to perform the job well.
CONTROL: • Level of input or influence the individual has in their workload and organisation • Lack of consultation during planning/execution of the job or when setting performance targets and
timescales •
Lack of time to complete the job (fast turnaround times, sudden changes to schedule of works)
SUPPORT: •
Encouragement, sponsorship and resources provided by the organisation, line management and colleagues
•
Lack of training and equipment to do the job effectively, efficiently and/or safely
•
Statistics regarding Mental ill Health in the workplace are available: https://mhfaengland. org/mhfa-centre/research-and-evaluation/ mental-health-statistics/#workplace
Leadership failures within the organisation (from micromanagement through to laissez-faire passivity)
•
Long working hours and inflexible shift patterns/schedules which impact on personal and family life
Six Primary Sources of Stress Identified by the HSE
•
Extensive commuting and travel times which add hours to the working day
The HSE identifies 6 primary sources of stress arising from the design of work and workloads:
•
Pay and other benefits may be interpreted as a direct reflection of the individual’s worth to the company
•
Lack of training for staff (at all levels) and career support (supervisory training, progress through to Chartership etc.)
Individual and management training awareness through e.g. the Mental Health First Aid England, (MHFA) is a great resource and starting point for the Ground Investigation Industry to engage, learn and disseminate best practice about workplace stress and anxiety and how to deal with it in the office or site environment. https://mhfaengland.org/.
DEMANDS: •
Includes issues such as workload, work patterns and the work environment
•
Unrealistic deadlines and expectations from management or clients
•
Unmanageable workloads (uneven distribution of work between staff, under resourcing or under-recruitment of staff)
RELATIONSHIPS: •
Promoting positive working to avoid conflict and dealing with unacceptable behaviour
•
Lack of support or isolation from peers

(e.g. field based staff with office based colleagues) •
•
Bullying and harassment (including exposure to violence or aggression) and the failure of the organisation to manage potential conflicts on site as well as in the office
Whether people understand their role within the organisation and whether the organisation ensures that they do not have conflicting roles
Appointment of “hand-holding” mentors to communicate and listen to new/young worker/graduates concerns
CHANGE: How organisational change is managed and communicated in the organisation. •
Changes in job role due to technology or changes in regulation or industry standards.
•
Uncertainty in relation to highly variable industry (recession, competition, limited company “future proofing”)
•
Lack of transparency in directorial or management decision making.
Lack of clear and consistent disciplinary procedures or reporting structures
ROLE: •

•
Lack of clear definition of an individual’s job description and reporting structure

The management standards are referenced in the HSE booklet INDG 424: Working together to reduce stress at work, an Employer’s Guide: http://www.hse.gov.uk/pubns/indg424.pdf These standards are intended to: •
Demonstrate good practice through a step by step risk assessment approach
•
Allow assessment of the current situation using surveys and other techniques
•
Promote active discussion across all levels of the company to consider practical

situations for both operators and managers alike. Factors for consideration that may contribute to Geotechnical and Geoenvironmental industry stress: •
The exploratory nature of geotechnical / geoenvironmental work means that often we identify unexpected conditions which will cause delay and cost to various parties, and therefore our members are often at the focal point of urgent and demanding requests to verify that scopes of works / designs / construction works do not need to be changed
•
Unforeseen conditions involve likely delays, additional costs, safety challenges and even blame for “getting it wrong”, and it can be difficult to have these approved quickly or even at all, thereby pressuring our members to make compromises
•
AGS members’ work is often towards the bottom of a complex supply chain leading to the client, and the instructing party may have different contractual expectations to the ultimate client
•
Ground-related delays have a huge impact on the overall construction programme, and this causes high levels of urgency
•
Our members are often required to work at very dispersed locations, away from home and family support

Q & A with...
Chaido Doulala-Rigby (Yuli)
BEng MSc CEng FInstRE FICE MHKIE MIMMM
Job Title: Business Development and Chief Civil Engineer Eastern Hemisphere (EH)
What or who inspired you to join the geotechnical industry?
My engineering journey started in Greece where I was born, grew up and got my first degree in Civil Engineering. In my 26 years engineering career so far, that spans across the globe, including 10 wonderful years in Hong Kong working as a Geotechnical Engineer, I feel blessed to have been part of some extraordinary projects and to have met some truly amazing people both on a personal level and professionally.
I owe my initial ‘attraction’ to Geotechnics predominately to Dr Evan Passaris, who was a professor at Newcastle University upon Tyne back in the early 90’s and encouraged me to do their MSc in Rock Mechanics and Foundation Engineering. Upon my MSc completion in 1994, I joined the Jubilee Line Extension (JLE – Contract 102) that was under construction in London, working as a graduate tunnel engineer for Balfour Beatty/ Amec JV. At the time, JLE was the largest Civil Engineering project in the UK and still remains one of the most expensive projects in the world of all times at over £4 million per meter of its 16km length!
Upon my return to the UK from HK some 14 years ago, I joined Tensar International and soon progressed to become the Chief Civil Engineer of the Company that invented Polymer Geogrid Technology and “revolutionised Civil Engineering” (as quoted in the ICE200 publication in 2018).
Looking back, I can confidently say that, while my MSc intrigued my appetite for Geotechnics, it was joining the JLE tunneling project that cemented my decision to follow Geotechnics. It taught me to expect the unexpected when dealing with soil, which fascinated me and encouraged me to further explore the weird and wonderful world of

Geotechnics. And here I am, just over a quarter of a century later, still in Geotechnics and still loving it!
What does a typical day entail? There is no such a thing as a ‘typical’ day and I guess that’s the best part of being an engineer, no 2 days are the same! I love travelling and I love educating people from all backgrounds about the magnificent performance of geosynthetics and especially Tensar’s leading geogrid technology. My current role is largely a combination of both. It is quite a demanding role, that I enjoy enormously, but I have worked very hard to earn it and I still work even harder to keep up with its ever-expanding nature. Many people say I am ‘lucky’. But I don’t believe in ‘luck’. I believe we can all create our own ‘luck’, and I find that the harder I work, the ‘luckier’ I get, meaning the more I get invited to travel for Tensar. What the people that call me ‘lucky’ don’t know is the amount of preparation that goes behind
Photo taken in front of Tensar’s 60m high geogrid reinforced soil walls in 2011 in Fujairah, UAE the ‘glamour’ of travelling. There are many reasons for my work related travel: to present bespoke technical papers that I author to International Conferences, to deliver bespoke design training to Tensar’s various EH offices that I look after, to present our cost, time and value message to suit specific Clients’ requirements, to present our latest R&D research to technical forums, to participate to committee/ panel meetings, to do STEM talks and/or activities with hundreds of school children and students, to review, interview and judge technical submissions of Industry projects’ entries on behalf of various independent Industry Awards such as Ground Engineering, ICE, Engineering Trust etc. What people that call me ‘lucky’ don’t see is the ‘red eye’ car, train and/or flight journeys that I take to get me to my destination on time and in the most efficient way and the weekends and early mornings or late nights that I spend on my kitchen table writing or assessing papers and preparing for my bespoke presentations. A large part of what I do is indeed voluntary and outside my normal, ‘day job’ working hours not because I ‘have to’ but because I choose to do so. Having gained so much
experience in Geotechnics and in Engineering at large over the years, it gives me great joy and pleasure to be able to share my knowledge and give back to the engineering community, whether it is by participating in committee work, Industry award judging or getting involved in STEM work. My ‘day job’ involves fast-track live project risk management by directing, advising, checking and indeed carrying out designs for Tensar’s multidisciplinary applications requests that land in my inbox daily from all over the world. Enquiries can vary from as simple as: “What fill can be used to build a 3m high car park retaining wall with your geogrids?” to “Can we build a 30m high dam with your geogrids?” to “Can you help us support a ~3,000ton crane over soggy paddy fields in Vietnam?!”. Or from: “Can you represent the ICE and talk
about What Is Civil Engineering to students in an upcoming Engineering Day event at a University in Manchester” to “Can you come to Peru next month to present Tensar’s containment capabilities to a mining Client”! So two days are never the same and it is this unpredictable variability of what I do that I love the most, not knowing what soil type, request or idea tomorrow brings! Undeniably, there are times that managing my ever-evolving to-do list can get frustrating too, but after all these years, I have learned to know when to close my laptop and remind myself, and other like-minded colleagues, that ‘tomorrow is another day’.
Are there any projects which you’re particularly proud to have been a part of? I take pride in every single project that I get involved with. But if I had to choose a March / April 2020

single construction project that I got involved with in my career so far, it has got to be Tensar’s tallest geogrid reinforced soil embankment walls in Fujairah, UAE, that were constructed in 2011. The project was a massive cut and fill exercise whereby in-situ Gabbro mountains were blasted to create rock cut slopes with heights in excess of 100m, while the blasted rock was crushed and reinforced with our geogrids to form massive 60m high soil embankments to cross the valleys in between the mountains to support a new freeway connecting Dubai with Fujairah port. Our reinforced soil embankments replaced the originally proposed viaducts due to the surplus of blasted rock available and due to the access and construction difficulties a viaduct construction would pose in such harsh and arid environment. I am very proud to have led the design and supply team of Tensar Engineers to deliver this project, that included remote resource 24

coordination, multicultural team engagement, and many site specific design alterations that I had to manage under very tight deadlines to best fit unforeseeable and challenging geomorphological conditions that were encountered during construction. And a few amazing trips to the site too! The other ‘project’, that I take immense pride to be part of, is my voluntary role as a registered STEM Ambassador, for which I am grateful to have Tensar’s full support. My involvement with STEM started in 2018, thanks to the British Army that invited me to role model my career in Civil Engineering to young female school students, at the first ever Army-supported STEM careers’ fair. The event, that saw 900 female students aged 11-18 participating, was organised at the Military Royal Academy Sandhurst in May 2018 in support to the UK Government that declared 2018 as ‘Year of Engineering’ in an effort to help close the skill and gender gap our Industry
is facing. The same event was repeated in 2019 but expanded over two days and attracted 2,000 school students of both gender and it is due to be repeated in 2020 scheduled to reach even more students from even more remote regions and form more underprivileged backgrounds, proving that there are no boundaries to engineering and that engineering is for all.
What are the most challenging aspects of your role? On a Company level, as the inventors and leaders of polymer geogrid technology for over 40 years, Tensar’s greatest frustration is that, together with other manufacturers now, despite the independently tried, tested and proven benefits of geosynthetics in reducing cost, time and carbon in earthworks construction, we are still trying to ‘convert’ vital sectors of our Industry like Highways and Railways and convince them to include geosynthetics in their design standards and codes, rather than still treating geosynthetics as a ‘departure’. In parallel, our added challenge is in trying to maintain top quality standards across the Industry and differentiate amongst the various geosynthetic products available in the market and their different functions. And although some companies, like Tensar, have invested a

I believe, is by moving our Industry towards Project 13 new business model that is based on an ‘enterprise’ rather than traditional transactional arrangements. But until we adopt and embed Project 13, I would like to see more Contracts won not just on lowest pricing but on technical scoring as well as reputation scoring of the Tenderer. On the cultural front, which is as important as the technical front in my opinion, the main change I would like to see in the Geotechnical and wider Construction Industry, is a change or rather ‘re-invention’ of individual behaviours from apathy to ownership and from routine acceptance to critical dialogue. As more and more disturbing details are coming to light from the Grenfell Tower tragedy, I think that our major focus as an Industry, should be to actively and loudly re-iterate and ‘re-enforce’ our ethical values to both practising young professionals and especially to students. Ethical behaviour, whether in personal or professional life can be taught. It is our responsibility to teach the future generations of engineers to be proud of their engineering achievements and to have a loud, firm voice when it comes to practising our professional code of conduct and our professional duty to warn. At any level. TECHNICAL EXCELLENCE must always come before any COMMERCIAL GAIN.

Some Client Guides and other publications are becoming out of date and so the BPWG is driving a programme of identifying and amending key publications. Although some recent updates have been published, such as the Selection of Geotechnical Soil Laboratory Testing guidance, the BPWG are working with the other Working Groups to continue this effort, starting with some of the most popular documents such as the Client’s Guide to Site Investigations. We are also continuously monitoring our website data to assess publication popularity.
3. New AGS Client Guides It can be difficult for our clients to know what the geoprofessional qualifications and designations mean and how
they fulfil their requirements and what value they offer. The BPWG has instigated preparation of two Client Guides to summarise the meaning of geo-professional affiliations. We have produced two draft documents, which are at review stage, one each to cover geo-environmental and geotechnical professionals. We will promote the new guidance within the AGS magazine once available to members. As a trade body dedicated to promoting best practice within the industry, we need to ensure that the advice we provide to our members is as current and accurate as possible and reaches as wide an audience as practicable. We are always keen to welcome new members into the BPWG and so for those interested in the governance of the AGS and wish to know how you can contribute to the BPWG, please contact the AGS Secretariat at ags@ags.org.uk.

SoBRA Early Careers Risk Assessment Workshop Wednesday 24th June 2020 Location: Atkins, The Axis, 10 Holliday Street, Birmingham, B1 1TF This workshop will provide early career professionals with the tools to be a better brownfield risk assessor in the context of geological knowledge and remedial needs. Talks and workshops presented by experts in each field will: • Provide an overview of key risk assessment frameworks (human health from soil, controlled waters, permanent gases and vapours); • Develop understanding of the key factors that commonly drive our model projections; • Explore how such model uncertainty may be reduced by good field practices, good site conceptualisation and selection of appropriate criteria; and • Provide attendees with an opportunity to network with their peers and attain confidence in a workshop environment. After the event a document will be produced summarising the outcomes of the workshops and highlighting key learning points and sharing common mistakes. This will be a useful resource to assist early career professionals in their risk assessments. More information can be found at: https://sobra.org.uk/events/
