ABOUT THE AGS

Chair’s Foreword This month’s magazine will mark the first as my time as AGS Chair, and I would like to extend a massive thank you to my predecessor Neil Parry for all of his hard work during his term. I am very much looking forward to my term as Chair and hope to continue the great work carried out by those who have held the post before me. As we reflect on the greatly successful delivery of the AGS Annual Conference 2019 on 3rd April, I am filled with positivity and excitement about the future of not only the AGS as an organisation, but the geotechnical and geoenvironmental industries as a whole. The great attendance, insightful content and deserving Award Winners at this year’s conference serves as evidence to the bright future we have ahead of us.

the Sponsorship Packages are almost sold out, so get in touch now to avoid missing out. In this issue of the magazine, we have insightful entries on collateral warranties, offered by David Hutchinson on behalf of the AGS Loss Prevention Working Group; a Q&A with RSK’s Roseanna Bloxham; confirmation of the winners for the 2019 AGS Awards; and how survey information can be utilised to identify sewers and drainage pipes. 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.

The AGS Loss Prevention Working Group has just published another paper for the Loss Prevention Guidance 2017 document, namely “Loss Prevention Guidance 024 – Collateral Warranties”. This gives guidance on the use of collateral warranties to confer rights related to the main contract of appointment on persons or organisations who are not party to that contract, ie third parties.

Notes from the Chair

New AGS Chair Julian Lovell discusses the state of the Association, wider industry and his aims and aspirations as the newly elected Chair

I

t is a great honour for me to have been voted on as Chair of the AGS during the Annual Conference in April. It also fills me with a little trepidation as I feel I am following a lot of great past Chairs and have a great responsibility to continue the good work they started.

only good traits for me as an individual but also for any organisation including the AGS.

I truly believe that we have some exceptional people within our industry and the young Engineer’s talks at Geotechnica last year I feel that the industry is in a good place, indicated that this will continue at least for the evidenced by the recent Annual Conference immediate generations. However, there are (formally known as Member’s Day) which influences such as the current procurement had one of its best attendances. There was processes which are far too a notable buzz around often (some might say the exhibition hall and This is an industry always) driving down conference and there was a which I have grown cost, which does not help real positive feel to the day. to love and I will help an industry or Clients This is an industry which to drive the AGS to to recognise true value. I have grown to love and I Considering this, as with will help to drive the AGS to continue to promote many industries, we find continue to promote all of all of the good work it ourselves in a fight to the the good work it does and does and contribute to bottom and aspects of our contribute to improving it. improving it. work which should develop So, what are my aspirations for pride, such as a good job the AGS and industry during my done and the technical quality of any such tenure? The industry has changed over the last jobs, become a secondary or even tertiary 30 years, in some ways for the better and some consideration. In March, we had our first not so. I have learnt over that time that it is meeting of the AGS Procurement of Ground important to want to do a good job, have pride Investigation Steering Group.

been set out to question the current system and to develop new approaches to improve procurement and understanding of Ground Investigations. This is not a small project but there appears to be a ground swell, with catastrophes such as Carillion failing, driving other industries to look at these processes. This will be a collaborative initiative led by the AGS, FPS and BDA and will engage with the wider geotechnical community and other industries.

industry which should drive the Association and not the Committees. With this in mind, I believe that the AGS is the industry’s body and therefore more people in the industry should get involved.

Communication is a very interesting subject and academics like Prof. Iain Stewart who gave a thought-provoking talk at the Annual Conference provide a different perspective on the subject. For the last 30 years I have attended conference after conference and Over the last five years, the AGS has set its meeting after meeting where we agree that stall out as an organisation and have started to ‘we must educate the client’. For the last 30 focus on delivery of our aims. It is now my duty years and previous to that we have clearly to move this forward. Improved engagement failed. We will always have educated clients internally within the industry such as Highways England, has started but there is still Network Rail etc but we We will always a lot of work to be done will also always have be very good at but we are also looking to Project Management talking amongst improve relationships with organisations, Main ourselves ... but unless academia and other sectors. Contractors, Developers who Currently, academia is also we will never truly educate. it is communicated looking to industry to help Principally, this is because in the client’s terms it, as many of the geology/ when we talk passionately and language we will environmental/earth related about what we do, we talk a continue to fail. graduate courses are battling different language and often declining numbers. There is a have very different goals. We desire amongst some of those establishments will always be very good at talking amongst to develop more courses and they understand ourselves and agreeing a way forward but that these should be developed to meet unless it is communicated in the client’s terms industry needs and therefore the AGS will have and language we will continue to fail. With the a role to play in this. We also need to develop a help of people like Iain and Hazel at University strategy to encourage students to pick those of Plymouth I believe we can make progress. courses otherwise the industry will be fighting However, we need to be able to communicate over less and less skilled people. with the client and if we truly believed we could ever educate the client then we would no As an organisation we have not been good at longer be ‘specialists’. communicating what we do as an organisation or as an industry to those outside of the AGS So, let’s recognise the true value we bring to Committees. AGS is renowned for the data the projects we are involved with and shout format but those involved in the Association about it, improve how we share best practice, know we represent the membership in so learn from lessons, share knowledge and many more ways and we are a very active collaborate better. That way we can provide a body. The AGS represents the geotechnical unified voice as AGS to promote and improve and geoenvironmental industry and it is the our industry.

Phil Crowcroft of ERM presented examples of Emerging Contaminants including Lead, Asbestos, Mercury, Phthalates, PFAS and Microplastics and the concerns surrounding these. During his presentation, Phil explained that not all ‘emerging contaminants’ were new substances but included contaminants which we now have a better understanding of their effect on the environment or

The final talk of the day was provided by James Macfarlane of Hydrock on Practical Asbestos Ground Investigations, who highlighted the industry have produced a number of guidance documents focusing on asbestos in soils and covered potential issues with asbestos on site investigations. This led to a discussion regarding the relevance and pragmatism of current guidance with relation to standard ground investigations. It is hoped that AGS will produce guidance to address this. 8

Using Survey Information for New Drains and Sewers

A

s pressure increases to use brownfield sites for new housing, the specialist skills involved in assessing the risks that contaminants pose to the quality of the water entering the surface water drainage and foul water sewerage system from the surrounding soil, is vitally important to house developers and water companies. The BPF Pipes Group has prepared a new guide “Designing drains and sewers for brownfield sites� providing drainage engineers with clear advice on choosing a pipe which will be fit for the long term, starting with the information available to them from the investigation of potentially contaminated land and drawing

on the materials expertise from pipe manufacturers.

Effect of contaminants on ingress An initial flow diagram in the guide sets out a step-by-step process for the drainage engineer to identify if a quantitative risk assessment has been carried out, whether the contaminants could pose a risk if left in the ground and whether the source or the pathway might be removed due to the proposed remediation plans. The geotechnical specialist undertaking the quantitative risk assessment and options appraisal can support the drainage engineer


by drawing out the essential information from the site history and soil sampling: •

confirming where there is (and is not) a possible source of contamination - this is particularly pertinent on large sites with a mixed history of use;

The BPF Pipes Group guide provides practical assistance on designing drains and sewers for brownfield sites.

clearly setting out what chemicals are present from the many included in the test report and in which zones (areas) of the site; and explaining the mitigation strategies proposed so that any impact on the source of contamination or the pathway can be recognised.

Suitability of materials for drains and sewers A second flow diagram in the guide assists the engineer to identify the impact that residual contaminants may have on plastic pipe materials. Where organic compounds are shown to be present in the soil, the guidance provides limits for PAH, BTEX and TPH which represent a safe level with respect to long-term performance of polypropylene, polyethylene and PVC-U pipes. The engineer is again reminded that any

remediation activities which might remove the source of the contamination or the pathway to the drainage or sewerage system would render these limits superfluous.

Working together The BPF Pipes Group guide provides practical assistance on designing drains and sewers for brownfield sites. However, to be truly useful to the drainage engineer, it requires that a risk assessment has been completed, an options appraisal has been carried out to identify solutions, and that the geotechnical specialist provides information in a form which can readily be used in the decision-making process. Working together, clear and targeted information can be offered, ensuring the longevity of the surface water drainage and foul sewerage networks on brownfield sites. The guide is available on its website at www. bpfpipesgroup.com/support-downloads/ guidance-notes.

Additional topics being discussed by the Geotechnical Working Group Other issues providing significant discussion within our group have included: suitable consideration of health and safety in ground investigation proposals, it is clear that CDM regulations are not being followed by many who procure ground investigation; inconsistency of terminology for common laboratory tests and resultant parameters, this is of particular importance when National scale projects use terminology different to that set out in relevant codes; suitable use of pile and anchor load testing to actually investigate the load carrying capacity of the ground these foundation elements are located within, “don’t be afraid to fail your test piles and anchors!”.

Q & A with...

Roseanna Bloxham BEng (Hons) FGS

Job Title: Senior Geoenvironmental Engineer Company: RSK Environment Ltd Brief Biography: I am a senior geoenvironmental engineer in the geosciences team at international environmental and engineering consultancy RSK. Based in our Hemel Hempstead office, I am a project manager, health and safety lead for RSK’s UK contract with Shell, on the ASG Safety Working Group, and have recently been invited to join the CL:AIRE Technology and Research Group. I am also a STEM ambassador and outside of work I am a Guide leader, volunteer at a local theatre, play hockey twice a week (and find time for the gym!)

What or who inspired you to join the geotechnical industry? I was never pushed to study engineering or take it on as a career, however having a father who is a civil engineer might have helped. From a young age I did not know exactly what I wanted to do and, to be honest, I still do not know what is in store for the future. At A-level I chose the subjects I enjoyed the most, which for me was physics, maths and physical education. Then when it came to choose a degree, all I knew was that I did not want an office job. I saw the engineering geology and geotechnics degree at the University of Portsmouth and it seemed like it was made for me: a perfect balance of fieldwork and class-based study leading me in to the geotechnical industry.

and enables me to develop my knowledge and skills every day.

Are there any projects which you’re particularly proud to have been a part of? I have thoroughly enjoyed all the projects I have worked on during my career with RSK but if I had to choose I would say working as health and safety lead on RSK’s Shell contract, as it has hugely shaped my career in terms of both development and my role within health and safety. In addition, my geotechnical expertise has improved significantly since working with Redrow on a large housing project, where I have been involved in the construction of several retaining walls.

What does a typical day entail?

What are the most challenging aspects of To be honest there is no ‘typical your role? day’ in this industry and I have found that no two days are the same. Every project we work on has its own challenges that need to be overcome. For me, this makes the job exciting

The most challenging part of my role is having the courage to say ‘no’. Project opportunities arise on a daily basis and knowing your limits within regards to time

Groups are you a Member of and what are your current focuses?

I am currently a member of the AGS Safety Working Group. Our focus is the creation of bespoke and clear guidance for ground engineers. We are currently working on updating several existing documents.

What do you find beneficial about being an AGS Member? The AGS helps to provide support to the industry and being part of the group enables me to have access to the excellent guidance they provide, and gain support and knowledge from other members.

Why do you feel the AGS is important to the industry? The AGS is an important hub for the industry and it is a great way of networking and sharing new ideas. It also provides essential guidance on ever changing standards and sheds light on complicated legal jargon.

What changes would you like to see implemented in the geotechnical industry? I would like to see an increased use in technology. The world is ever changing and every day we are seeing further developments to improve our future. Rather than fearing its capabilities we need to embrace what technology can do to improve or replace existing techniques.

GOOD PRACTICE IN GEOENVIRONMENTAL GROUND INVESTIGATION – UPDATE An opinion piece, written by Chris Swainston, Principal Environmental Engineer at Soils Limited Photo credit: Josh Simmonds

I

t has long been the aim of the Contaminated Land Working Group to produce a definitive guide to ground investigation good practice similar to that produced for Geotechnical Ground Investigation in 2016. As with many things in life, I feel that this has rather been eclipsed by events.

“

With the publication of the ISO BS 18400 series on Soil Quality, hopefully some of this existing variation will be resolved, rationalised and summarised to some extent.

The definition of good practice has certainly changed over time and the available standards and guidance available from BSI, ISO, CEN, AGS, CIRIA, CL:AIRE and many others continues to develop around us. Indeed, there is a veritable treasure trove of training and advice available on almost any aspect of site investigation, sampling and monitoring you care to consider and keeping up with them all, and especially acting on them, can be a job in itself. This is even more true if you subscribe to or work under ISO9001 et al. With the publication of the ISO BS 18400 series on Soil Quality, hopefully some of this existing variation will be resolved, rationalised and

summarised to some extent.

Having been in this business for over 25 years now, training students, young practitioners and fellow professionals in the art and science of site investigation, sampling and monitoring as well as being current chair of BSI EH/4 (responsible for BS10175), I am perhaps more aware than most of the sheer range of material out there. Indeed, I have noted on previous occasions that if stacked on top of each other, the guidance alone would probably reach to your waist. So, do we really need any more guidance on this topic? Well perhaps the main reason for doing so would be to at least provide a road map and summary of where to find all the other information you might need to know (or at least should know about) when undertaking or commissioning a ground investigation. Firstly though, we should step back and consider what ground investigation actually is


and why we undertake them in the first place. In simple terms investigation is the process used to determine and quantify remaining unknowns from the Conceptual Site Model (CSM). As such, actual ground investigation can come in many forms, types, phases and be given many (often confusing) names depending on how, where, when and what is planned. For a Desk Study or preliminary investigation for example this is usually as a site visit and observation and then remotely from the office following a review of the available data.

the ground and finding out what’s there. What happens afterwards is a whole topic and world of its own beyond the scope of consideration in this discussion, but should be considered and questioned when designing any investigation. What you plan to do with the data you will gather should in part, through consideration of the CSM, resources, available analysis, analytical tools available, etc. dictate what data you actually get from the investigation. Failure to appreciate this aspect from the start of the process can sometimes lead to quite significant problems and What you plan costs further down the line.

If, following an initial to do with the data assessment of the CSM, So, where do we go from you will gather should a risk has the potential here? Well a good stop-gap in part [...] dictate what to be present, potentially and the method I would data you actually get significant unknowns remain generally suggest at the from the investigation. and/or further quantification moment as a starting of perceived issues is required, point to anyone who asks, we then move on to designing is to look to the various the intrusive or main investigation phase. This standards that guidance themselves reference, should be based on and reflect consideration especially given that all good practice should of a range of factors depending on both what ultimately be standards driven or at least we know and what we don’t and should backed by standard references. BS10175 is ultimately dictate where we look, sample, a good summary of most of what you need install and monitor real world locations and to know when investigating potentially materials. This can be followed by any number contaminated land and has extensive of additional supplementary investigations to references to other relevant standards confirm specific aspects, the most common of including in the most recent update/revision, which is probably undertaken to determine the the BS ISO 18400 series. So how would I write extents, composition and nature of identified an AGS guidance note for good practice in deleterious materials to thereby assist in Geoenvironmental ground investigation? Well the production of a site-specific materials I can certainly think of worse than a white management plans and/or remediation page with a large arrow pointing to the latest strategy. version of BS10175 and the BS ISO 18400 series. But, as I chair of the committee that looks after So, given the above, what is Geoenvironmental all of this for BSI, I suppose I would say that Ground Investigation? This is somewhat of an wouldn’t I…. open question really and as with many things depends ultimately on context and perception.
