Tags: Featured

The United Kingdom Accreditation Service (UKAS) is establishing a pilot programme for the development of accreditation for ‘ISO 17020:2012 for the surveying of contaminated land for the presence of asbestos’. Essentially, asbestos surveyors (conversant with building surveys relating to management, refurbishment or demolition) could be undertaking the work of a contaminated land professional – without the relevant training, experience, competency or accreditation for investigating potentially contaminated land.

UKAS has held discussions with a number of parties regarding accreditation including representatives of the AGS, the National Brownfield Forum and SAGTA. These parties have raised considerable concerns principally because the proposals fail to understand the contaminated land investigation process.

UKAS has failed to address these concerns and the AGS Contaminated Land Working Group now feel we need to take this issue to our members and we are asking for your feedback by answering the poll below.

If you wish to provide further comments please do so.

The results of this poll will be shared with UKAS. The poll will close on 15th January 2021.

After a successful webinar on 8th December 2020 AGS 4.1 is now available free of charge for download from www.ags.org.uk/data-format. The original AGS 4.0 document has been completely reviewed and AGS 4.1 represents a substantial update to the Data Dictionary including significant modifications to 14 existing groups and more importantly adding 24 new groups and 788 headings to introduce the following new subjects:

  • Major improvements for handling geoenvironmental data and environmental containers
  • Advanced laboratory testing
  • Drillers descriptions
  • Field geohydraulic testing
  • Wireline geophysics

To support the release of AGS 4.1, we have launched a new website found at www.ags.org.uk/data-format to facilitate:

  • improved discussion board interaction
  • published a road map for the future of the AGS Data Format
  • added a new searchable change log for the updates to AGS 4.1
  • improved search and download facilities for groups and headings, abbreviations, units and data types
  • easier route to proposed new headings, abbreviations, units and data types
  • easy access to previous versions of the format for reference purposes

We are immensely proud of the enormous effort the group has put into both AGSi and AGS 4.1 this year and would like to thank each member of the Data Management Working Group for their dedication to the industry, not forgetting our thanks also to their companies for the work-time donated to the AGS in 2020. The group will be having a well-earned rest over Christmas and the New Year before moving on to plans for the postponed Data Conference now happening on 22nd September 2021 at the National Motorcycle Museum, Birmingham.

On 25th November, the AGS hosted a webinar entitled, Exchange of Ground Model and Interpreted Data – Introducing AGSi. The event, which was generously sponsored by Jacobs, marked the official launch of AGSi, which has been developed by the AGS Data Management Working Group.

Members of the AGSi sub-working group presented on the new exchange format released as beta during the webinar. Event presenters included Jérôme Chamfray (Chief Geo-Digital Engineer at Jacobs), Neil Chadwick (Independent Consultant & Digital Geotechnical Specialist), David Farmer (Geotechnical Engineer at Arup), Osvaldas Tylenis (Senior Software Engineer at Bentley Systems), Tony Daly (Managing Director at Amageo) and Julian Lovell, (Managing Director, Equipe Group and AGS Chair).

The virtual event was attended by delegates in USA, Canada, Brazil, India, South Africa, Australia, Russia, Malaysia, Europe and beyond.  Over 650 delegates registered for the free webinar, which was attended by specialists from various backgrounds including ground specialists, data scientists and software developers.

AGSi is a new format which has been created for anyone involved in the construction or sharing of ground models, whether they be geological, geotechnical, hydrogeological or geo-environmental, or as a solution for anyone who has found themselves looking for:

  • An industry standard non-proprietary method for transferring a ground model and/or interpreted geotechnical parameters to another organisation.
  • A way of importing your ground model into a BIM model that does not involve lots of reprocessing or data loss.
  • A common data format for ground information that your analysis software can understand, making automation of design workflows much easier.

The AGSi documentation is now live and can be accessed via the AGS website, under AGS Data Format (see below extract).

The AGSi sub-working group is looking for volunteers to contribute further in the development of the format so if you are a software developer, ground specialist with some coding experience or interested to learn more please reach out using the AGSi documentation site or by emailing ags@ags.org.uk.

If you missed this webinar, the recording is now live and available for free view on the AGS website which can be viewed HERE. Alternatively, it is available on the AGS’ Vimeo channel HERE.

AGS Webinar: Critical Links in Ground Engineering

- by
Tags: Featured

On 4 November 2020, AGS held the first of what is expected to be a series of Webinars and Seminars under the title “Critical Links in Ground Engineering”.

The subject of the November Webinar was Instrumentation and Monitoring (I&M), with a future Webinar expected to be about Laboratory Testing.

The Webinar lasted for four hours, including a short break in proceedings, with an audience which comprised of nearly 70% consultants and I&M specialists, about 20% contractors, and just over 10% client organisations and academics.

The Webinar was introduced by Julian Lovell, Chairman of AGS, who also – in his capacity as Managing Director of the Equipe Group – contributed to proceedings with a concluding presentation addressing the UK’s strategy to develop training for installation and monitoring technicians which dovetails in with the development of Vocational Qualifications and compliance with the Standards.  Wider issues of education, training and qualifications were also included in this presentation.

Jonathan Gammon, as Leader of AGS’s I&M Working Group and Non-Executive Director / Advisor at Geotechnical Observations Limited, gave the first presentation, describing the scope and types of I&M and identifying the role of I&M as a critical link in Ground Engineering.

Philip Child, Senior Consultant, Geotechnical Information Management, at Bentley Systems followed with a presentation entitled “Data – Overhead, Deliverable, or Opportunity” which tackled the challenging issue of I&M data management and proposed an alternative way of thinking about data.  Attention was given to the specifics of working with monitoring data and the possibilities it provides.

Presenting live from New Zealand in the middle of the night there, Paul Burton, Executive Leader at Geotechnics (New Zealand) described the I&M situation in Australasia, providing a personal perspective on the challenges of I&M work in this region and introducing a valuable global dimension to proceedings.

Andrew Ridley, Managing Director of Geotechnical Observations Limited, then tackled the subject of international standards for geotechnical monitoring, tracing in particular their development and content from 2010 to the present day.  Standards currently in preparation, as well as those anticipated in the future, were identified, as were Technical Committees that have been formed to address I&M.

Opportunities were given to question the presenters during the Webinar.  Matters raised during the Q&A sessions included: responsibility for data interpretation; shortcomings of some Cloud platforms; the ability of AGS Format to accommodate the whole range of instruments and monitoring techniques now available; appropriate training of site staff and the skills set required; data formats developed in other countries in other languages; global growth of I&M and challenges in securing rapid delivery of instruments; the ability to access I&M data collected by others, with reference to national I&M databases available to all; liabilities associated with relying on I&M data provided by others; the specification of correction methods for instruments such as inclinometers; the durability of instruments and increased demands on their longevity.

The work of AGS on matters of relevance to I&M, including the revision of the UK’s “Yellow Book”, was described by Julian as he brought the Webinar to a close.

Additional Polls identified that just under 20% of attendees had a Civil Engineering professional qualification and almost 60% had a Geology professional qualification.  Countries represented stretched around the Globe from South America to New Zealand, so this was truly an international event.

Valuable feedback was received after the Webinar.  This was the first AGS Webinar for which payment was required.  On the day it was also competing for attention with the GE Awards, commencing immediately after the end of the Webinar, and the BGA AGM and Technical Presentation that evening.  So, it was very encouraging to find that it was rated overall at just over four stars out of five and 90% of the audience found it to be the correct length.  All agreed that they had gained new knowledge applicable to their work and a four-and-a-half stars out of five rating was given to attending future AGS webinars and recommending these Webinars to others.  Very helpful suggestions for the improvement of future Webinars and for future Webinar topics were also provided and have already received attention from AGS’s Executive.

The Critical Links in Ground Engineering webinar recording is now available for view on the AGS website by clicking HERE. This webinar is three hours long and is available at the reduced AGS member rate of £72, or the non-member rate of £108. All prices include VAT.

We’d like to extend our thanks to our brilliant line-up of presenters who made this event possible; Jonathan Gammon, Phil Child, Paul Burton, Dr Andrew Ridley and Julian Lovell. Thank you also to our five webinar sponsors; Geotechnical Observations, Geosense, Measurand, RST Instruments and Senceive.

SiLC perspective on publication of Environment Agency guidance Land Contamination Risk Management (LCRM)

- by
Tags: Featured SiLC

By Dr. Tom Henman, Deputy Chair, Professional & Technical Panel, SiLC PTP

After a delay due to Covid-19, Land Contamination Risk Management (LCRM) was finally published by the Environment Agency in October 2020. LCRM replaces CLR11 Model Procedures for the Management of Land Contamination as guidance and the framework for all who are involved in or responsible for managing risks from land contamination in England.

The overall approach to risk management and remediation in LCRM is the same as the withdrawn Model Procedures for the Management of Contaminated Land (CLR11). However, two key elements are prominent in LCRM –which are particularly relevant to SiLC – relating to competence and the National Quality Mark Scheme for Land Contamination Management (NQMS).

LCRM makes prominent reference to the NQMS, which is a voluntary scheme set up by the National Brownfield Forum, and designed to improve confidence in the quality of land contamination reports. Suitably Qualified Persons (SQPs) who sign-off NQMS reports are accredited through the SiLC examination process and the SiLC Professional and Technical Panel is a strong advocate of the NQMS.

As well as highlighting the value of applying the NQMS to reports, LCRM also stresses the importance of identifying any uncertainties and limitations of data and any possible consequences. This is a mandatory requirement for sign-off of reports registered under the NQMS.

LCRM also states the expectation that those undertaking land contamination assessment and remediation will be competent at all stages. This means having the appropriate knowledge, skills, experience and qualifications in each specific area of LCRM and the type of contamination being dealt with. For planning related assessments, LCRM also refers to the National Planning Policy Framework definition of a competent person, i.e. ‘with a recognised relevant qualification, sufficient experience in dealing with the type(s) of pollution or land instability, and membership of a relevant professional organisation’. The SiLC Register was developed precisely with these considerations in mind, so this emphasis on competence is welcomed. Both SiLC and SQPs registered under the NQMS are referenced specifically in LCRM as appropriate qualifications to demonstrate competence.

Overall, SiLC welcomes the new guidance and its emphasis on high quality assessments by competent professionals as well as the application of the NQMS. For more information about the SiLC Register, please visit www.silc.org.uk.

Notes on SiLC:

The Specialist in Land Condition (SiLC) Register scheme was designed to support the recommendations of the Urban Task Force in 1999 and to recognise the skills of those working in the broader land condition sector.

A registered SiLC is a senior practitioner who has a broad awareness, knowledge and understanding of land condition issues, providing impartial and professional advice in their field of expertise. Entry to SiLC is gained through examination, which is held bi-annually. The SiLC Register brings together professionals from a broad range of backgrounds who advise on land condition matters.

The SiLC Register is run and administered by a Professional and Technical Panel (PTP), which comprises representatives from the supporting professional bodies and senior professionals. The PTP develops and implements the registration process and is the ruling committee for individual registrations.

Professional Indemnity Insurance Update

- by

As we commence a New Year, the availability and cost of Professional Indemnity (PI) insurance remains a key concern for many practices.  It is likely that many will have experienced the consequence of market contraction throughout 2020 and unfortunately, with insurance capacity continuing to decline, 2021 is unlikely to offer any respite.

It is therefore more important than ever to understand what is driving insurers’ current thinking and what firms can do to protect their position.

Understanding the insurance market cycle

Like many other financial institutions, insurers are bound by capital solvency requirements.
This means that they need to maintain a certain ratio of assets to liabilities to ensure they can meet their obligation to pay claims.  The amount of business an insurer can write is dependent upon the amount of capital they hold in reserve.  When the supply of capital reduces, insurers will take on less business and when it is readily available, they will be able to write more.  That fluctuation in the availability of capital is a key driver of the insurance market cycle, and in turn, the availability and cost of insurance.

Reports suggest that there has been an ‘over supply’ of capital in recent years.  This, coupled with ever increasing commercial pressures, has contributed to a relaxation of underwriting discipline.  In other words, the level of competition within the PI sector has led to behaviours such as the under-pricing of risk, taking on too much exposure and making insufficient allowance for claims.

As the effects of that manifest, the return on investment reduces and capital begins to withdraw from the market; many insurers are not able to take on the same volume of business and some (as we are now seeing) may withdraw from certain market segments (e.g. professions or types of work) or entire classes of insurance.

As a result, problems can arise with the availability and cost of insurance and the breadth of cover provided.

Particular PI insurance challenges for Consultants in the Built Environment

As a specialist class of insurance with long-tail liabilities, PI insurance has traditionally been more susceptible to significant changes than the wider insurance market. Allied to that, is the perceived evolution in risk profile of the construction / built environment sector.

Although the PI market looked very different in early 2017, the cracks were already beginning to show. Even at that point, there was an acknowledged growing risk versus reward imbalance, with construction professionals being asked to do more, for less, under increasingly onerous contracts.

Unaware or unconcerned with the implications, certain insurers continued to focus on growth in (or retention of) market share rather than long-term viability.  Those behaviours were impacting the market, and it was only a matter of time before the effects of that would take hold and capital would begin to exit.

Even before anyone had heard of COVID-19, it seemed inevitable that conditions within the PI insurance market were set to change.  The impact of the combination of events over the last few years: the failure of major contractors; the tragedy of Grenfell and subsequent questions concerning the quality of our buildings; the regulation of construction and the resultant potential legacy risk for insurers.

The availability of insurance capacity will be one of the biggest challenges as we move through the year ahead. It is inevitable that the market will continue to contract and with that we are likely to see a much harder line taken by those Insurers that continue to offer capital within the PI sector for those professions active in the built environment. Insureds should be prepared for:

Further premium increases: By how much is very difficult to say, as this will be heavily dependent upon how low your insurers have been prepared to cede to market pressures in the past. Those insurers that have focused purely on market share at any price will be the ones that are in the greatest need of corrective action to their book of business. Some insurers simply felt that correction was commercially impossible and have exited the market altogether Those that remain can be a lot more selective about which risks they will take on. In some cases, insurers may not offer renewal terms to those exposed to higher risk areas of work or to those practices with poor claims performance.

Higher excess levels: Those practices that are currently paying an excess of less than 1% of their fee income should expect to see higher excesses being imposed. For some areas of high-risk work, insurers may insist that the excess is also applied to defence costs.

Narrowing of coverage: Any one claim coverage has long been a feature of the UK PI market, although AGS members will be aware that any one claim coverage was removed some 20 years ago in relation to pollution and asbestos, with most insurers restricting coverage to aggregate limits only.  In the current marketplace, aggregation of all elements of coverage is being introduced as a way to deal with exposure to other high-risk areas of work. Unfortunately, for the geotechnical sector they are generally viewed as working in the part of the project cycle with the most severe risks and therefore when a hard market sets in, they are often amongst the first to be hit with the most severe coverage restrictions.

What can Insureds do to protect their position?

There is no doubt that the year ahead will be a challenging one commercially. Whilst it is not possible to control what is happening within the Insurance market, there are some steps that insureds can take to help navigate the difficult road ahead.

Early engagement with your broker is vital to ensure you have time to deal with issues that may arise throughout the renewal process. In 2021, time will be a required asset not a luxury. If your insurer has chosen to withdraw from the geotechnical sector or is only prepared to offer aggregated coverage, the earlier you know about this the more time you have to explore alternative solutions. Even small practices should engage with their broker at least 2 months in advance to ensure there is sufficient time to navigate problems that could well arise. Much larger practices should be engaging 6-months ahead of renewal date.

Insurers are requesting far more information than ever before – be prepared to answer additional questions about your Business, particularly around activities of work that will be deemed by the insurers as ‘higher-risk’. AGS members are more likely to be exposed to higher-risk activities by the very nature of the work they undertake (contaminated land, asbestos, basements, tunnels, railways to name but a few).

With the implementation of lockdown and most practices working from home, businesses have had to rapidly adapt their working practices. Insurers will want to understand how risk management procedures continue to be implemented in this changed environment. How do you go about the Q+A process, who signs off on work undertaken by more junior staff etc.? Many insurers now have a question set around COVID-19 and how the business is dealing with the new challenges this presents.

Insurers will want to understand your contractual risk management procedures: do you use them; are you successful in managing liability by way of financial caps and exclusions? do you use industry standard documents?

For those who have been unfortunate enough to be involved in a claim, prepare to be under more scrutiny. A post claim review may be required by insurers but even where it isn’t, drawing up a ‘lessons learned’ document can be a highly effective way to show that you have actively taken steps to avoid running into the same issues.

Work closely with your broker to help to identify particular risks that your business presents to the market and construct a narrative around why those risks have been identified, and how they have been understood and mitigated. Do not underestimate the value of a well conceived and constructed narrative or indeed a general overview of the way in which your business operates. If you can tell a good story about how you run your business, you need to make sure that your insurer hears it from a source that they respect.

At the end of the day, PI costs are going up. The more that you understand insurers’ concerns and, more importantly, how effectively your submission addresses those concerns, the better.

Griffiths & Armour Professional Risks are specialist professional indemnity brokers and risk managers. We advise a number of professional bodies across the construction industry, including ACE, and our specialist Scheme includes many AGS members.

Griffiths & Armour are not immune to changes within the PI market but our long-term approach to sustainable placement and trusted status in the insurance community mean that we remain capable of securing ‘Any One Claim’ cover notwithstanding the general market move to ‘Aggregate’ limits in your sector.

If you have concerns regarding your existing PI arrangements, we would be more than happy to discuss these with you.  Don’t wait until renewal is upon you, do get in touch early and let’s make sure we have sufficient time to help you achieve the best possible outcome.

Q&A with David Hutchinson

- by
Tags: Featured

Name:  David Hutchinson
Job Title:  Route Asset Manager (Geotechnics) – Now retired
Company:  Network Rail Infrastructure Limited

During my geotechnical career I have worked for a variety of organisations in consulting, contracting and asset management in the UK, Canada, Republic of Ireland, United Arab Emirates and Hong Kong.  For the last 14 years of my career, up to 2017 when I retired, I worked in Network Rail, firstly for Network Rail (CTRL) as the Civil Engineering Asset Manager for the High Speed 1 railway, and then as Network Rail’s Geotechnical and Drainage Route Asset Manager for the London North Eastern and East Midlands Routes, based in York.

What or who inspired you to join the geotechnical industry?
In the second year of a general engineering degree I attended a short course on Soil Mechanics given by Professor Andrew Schofield which inspired me to undertake half of my final year studying Soil Mechanics and Geotechnical Engineering under Andrew, Dr Peter Wroth and others.  I then joined Soil Mechanics Limited, who encouraged their graduates to attain a second degree.  Imperial College was the choice for many, but I wanted to go further afield, and so studied at the University of Alberta under Professor Morgenstern, who like Andrew Schofield and Peter Wroth was a Rankine lecturer of the early 1980’s. The enthusiasm of geotechnical practitioners and academics for their subject has kept me in this industry for my whole career.

What does a typical day entail?  
There hasn’t really been a “typical day”.  But while working for the railway my phone was with me 24/7.  (Night time calls from railway control heralding some disaster or other were not unusual – guaranteed to dramatically increase the heart rate!)  First thing in the morning I always checked the weather forecast to see what challenges nature was going to throw at me that day, and then checked my emails to see what challenges I was going to get from my colleagues!  Although retired I still check the weather forecast and emails every morning, but at night always leave my mobile phone out of earshot!

Are there any projects which you’re particularly proud of? 
Over the years I have worked on many projects, and I’m proud of them all.  But I’m particularly proud of the people I have worked with, from the drillers in my earliest days supervising ground investigations, through my resident site staff on Landslip Preventive Measures works in Hong Kong, to the team working with me in York.  I like my HK Government given Chinese name 夏,智信 which sounds like my surname and translates as “Mr Summer, wise and trustworthy”!  But my proudest moment was when my line manager in York, in front of my peers, held up my staff as an example of a high performing team!  My advice is to always surround yourself with able and enthusiastic people!

What are the most challenging aspects of your role?  
The challenges at Network Rail were mostly administrative, particularly new initiatives and reorganisations.  I had 8 different line managers during my last 7 years of full-time work!  But the geotechnical task remained the same, and being a small specialist discipline, we were usually left to get on with the job.  It’s very satisfying when things are going smoothly, but there are periods of intense pressure when the railway is closed by a landslip, particularly if a train is derailed.  Route Asset Managers are Key Safety Posts having ultimate responsibility for the actions and consequences of the work of their team regarding passenger and public safety.  However, managing such incidents is the most “exciting” part of the job – leading the recovery by rapidly assessing the problem and the time needed to fix it, organising the response, communicating with the parties affected, and completing the work quickly and safely within the timescales you have given.  My rule was always under promise and over deliver (extending promised completion dates does not go down well!).

What AGS Working Groups are you a member of, and what are your current focusses?
I have been a member of the Loss Prevention Working Group since 2003.  Being in the LPWG and employed by a client organisation is rather unusual, as one of the group’s aims is to minimise our members’ business risks when dealing with their clients!   I became interested in the law in the 1980s while investigating geotechnical failures for cases of litigation in the High Court.  In Hong Kong I had the opportunity to study for a law degree, and on return to the UK a former colleague and chair of the AGS suggested I join the LPWG.  In 2007 (actually while standing in a WW1 German trench on Vimy Ridge!) I received a call asking if I would like to become LPWG chair, a post I held until 2014.  I joined the Business Practice Working Group in 2019.

Since 2003 I have helped to produce AGS documents such as Loss Prevention Alerts, Client Guides and Guidance generally, over a range of topics.  Currently I am updating our Guide to Training Paths for Geoprofessionals, and producing a Client’s Guide to the Selection of Geotechnical Advisers.  I review the downloads of AGS documents from the website to help spot trends and determine which topics are of most interest to our members, and I am updating our archives by collecting copies of published AGS documents which are no longer available for downloading.

What do you enjoy most about being an AGS member? 
I enjoy making a contribution to an industry which has given me the opportunity to work and live in a number of interesting places and to meet so many interesting people.  I want to help clients better understand the issues facing geotechnical practitioners, and to help clients better manage their infrastructure, in particular in the transport sector where I am continuing my membership of the Geotechnical Asset Owners Forum as the AGS representative.

What does your company find beneficial about being an AGS Member?
One of Network Rail’s aims is to create professional and mutually beneficial relationships with its suppliers.  In 2013 NR became the first AGS Client Affiliate Member.  The activities of the AGS and the documents it publishes help NR geotechnical staff broaden their knowledge and experience of the current issues in the industry.

Why do you feel the AGS is important to the industry?
The country must maintain its ability to deliver new infrastructure quickly, efficiently, cost effectively and without damaging existing infrastructure or endangering lives.  The infrastructure must then be maintained to high standards.  The AGS helps to maintain high standards and integrity of ground engineering and geoenvironmental practice, disseminating up to date practical knowledge including industry relevant health and safety guidance, minimising business risks and presenting a coherent industry voice.  It provides a forum for dialogue within the industry, and informs clients and other professionals how to engage with and what to expect from their geotechnical and geoenviromental advisers.  It also helps to explain to clients the risks associated with different engineering solutions and that lowest price for geotechnical and geoenvironmental work does not necessarily give the best investment and long term value for their project.

What changes would you like to be implemented in the industry?
The industry needs to be attractive to a diverse workforce, as described in a recent AGS webinar, to help reduce future shortages of skilled people.  It must continue to strive for more widespread use of ground information in the AGS data format.  Use of remote sensing, readings from large numbers of sensors on or in the ground and digital data from ground investigations will lead to the use of novel analytical techniques including machine learning and artificial intelligence.  People with the relevant data management and computing skills will be needed to carry out this work, in addition to those with civil engineering, geology and geoscience backgrounds.  A wider discussion is required on how the industry can reduce its carbon usage.

Standards Relating to Investigation, Assessment, Remediation and Development of Potentially Contaminated and Contaminated Sites

Tags: Featured

Article provided by Mike Smith, Vice-Chair, BSI committee EH4-Soil quality

This new AGS guidance document provides key information required for a proper understanding and use Standard Guidance documents and Standard Specifications such as conventions in the use of language and the need for consistent use of terminology. It also provides information about in which Standards guidance on various topics such as investigation, reporting and remediation can be found.

BS 10175:2011 + A2:2017 Investigation of potentially contaminated sites -Code of practice is the key British Standard relating to the investigation and development of potentially, and proven, contaminated land. However, its proper application depends on following the recommendations or requirements of a constellation of other standards documents (Guidance and Specifications) many of which are European and/or International Standards- see Figure 1. Of particular importance are BS 8576: 2013 Guidance on investigations for ground gas – Permanent gases and Volatile Organic Compounds, BS 10176:2020 Taking soil samples for determination of volatile organic compounds (VOCs) – Specification and the BS ISO 18400 Soil quality – Sampling series of standards. BS 5930:2015 + A1:2020 Code of practice for ground investigations is important not only in respect of geotechnical investigations but also for the guidance it provides on combined geotechnical and geoenvironmental investigations.

Over two hundred guidance documents and Specifications have been produced by the ISO and CEN Technical Committees responsible for soil quality (ISO TC190 Soil quality and CEN TC444 Environmental characterization of solid matrices) including chemical analytical methods, physical test methods, biological test methods and guidance on what to look for when investigations are required for particular purposes. In line with the scopes of BS EH4 Soil quality (the relevant BSI committee), CEN TC 444 and ISO TC190, these various documents cover not only potentially contaminated sites, but natural and near-natural (e.g. farmed) soils, and contribute to understanding interactions between soil and global warming; concepts such as the health of the soil, sustainable use of soil and ecosystem services; and the actual and potential environmental impacts of existing and new chemicals

It is important to recognise that Standards are consensus documents prepared by technical experts and are subject to public consultation – any member of the public is entitled to see and comment on them, but the continuing difficulty that BSI EH4 has in meeting its obligations in this respect is how to let potentially interested parties know that draft documents exist. The formal position is that the representatives of organisations such as AGS are expected to inform and communicate with those they represent (so if you think you are missing out on information about draft standards the first route for complaint should be to AGS or other organisations to which you belong).

EH4 actively seeks to broaden its membership. The wider the membership of EH4, the greater the confidence that the standards produced are technically sound and known about by potential users from a wide variety of backgrounds.  It also increases the pool of people from which it might be possible to draw on from time to time to represent the UK in ISO and CEN Working Groups.

Most of the members of EH4 represent a nominating body but membership is also open to individuals with particular expertise.  BSI provides guidance on its web site on how to get involved with standards (How to get involved with standards). All enquiries will be sent to the relevant committee manager. Alternatively, contact the Committee Manager Jessy Matthew (Jessy.Mathew@bsigroup.com ).

Q&A with Madeleine Bardsley

Full Name: Madeleine Bardsley
Job Title: Associate Director
Company: Wood Group

I have spent 20 years in geoenvironmental consultancy.  My first taste of site work was as a sponsored student with Taylor Woodrow. After graduating I joined Dames & Moore and worked on ground investigations and remediation schemes.  To get through ICE Chartership, I moved to Mott MacDonald and worked on a mixture of geotechnical and geoenvironmental projects.  In 2002, I decided to focus on land quality projects and joined Enviros’ London team led by Hugh Mallett, whose enthusiasm and knowledge created a perfect environment for learning.  After 13 years, I moved to Wood and now work with a great group of people in the Remediation and Ground Engineering Team.

What or who inspired you to join the geotechnical industry?
At school I loved maths and physics and wanted a career where there was a practical application for your efforts, which led me to civil engineering.  During my degree at UCL, the subject that interested me most was soil mechanics and my lecturer – Dr Richard Bassett – suggested I continue studies by doing a PhD.  I moved universities to Cambridge and studied under Dr Chrysanthi Savvidou looking at a remediation technique using electricity called electrokinetics. Both lecturers inspired me and passed on their enthusiasm for their subject and confidence in my ability.

What does a typical day entail?
One of the joys of our industry is the variety of clients, project scopes and types of sites that we come across.  I’ve been lucky to work on a diverse range of sites including: defence, fuel depots, waste plants, gasworks and housing developments.  Every project is different and there is usually a challenge to keep you interested.

I know it’s a cliché but there really is no ‘typical’ day – I might be reviewing a report, meeting a client, visiting a site, working on initiatives to improve health and safety in our projects, carrying out a principal designer review of a project, organising a team meeting or holding a colleague’s personal development review.  I love the variety.

Are there any projects which you’re particularly proud to have been a part of?
The projects I am most proud of are the ones that I have seen through from contaminated ground to completion of the remediation – bringing land back into use. One project for Brent Council springs to mind, where we investigated and remediated the gardens within a residential part of the borough having successfully applied for funding under Part 2A.  I was Project Director and the client was knowledgeable, decisive and easy to work with.

It’s not a project but I enjoyed being part of the AGS steering group that revised the UK Specification for Ground Investigation (known as the ‘Yellow Book’). I learned a lot from the other members of the Steering Group and am proud of the revised document.

What are the most challenging aspects of your role?
I would say juggling all the demands of the different parts of my role.  I manage a team across three offices, lead on health and safety for Wood’s national team including carrying out Principal Designer reviews, and provide technical direction for several projects.

This year has been a huge challenge and, as most of the team are working from home, it has been difficult keeping people connected and finding the time between numerous Teams calls to stay in touch with colleagues.

What AGS Working Group(s) are you a Member of and what are your current focuses?
I have been a member of the AGS Health and Safety Working Group for over 15 years.  I’ve recently updated the AGS publication on ‘dealing with contamination during an intrusive investigation’ and now I am looking at health issues associated with using vacuum excavation in soils with asbestos where the asbestos is not visible. I’m also part of the recently formed sub-group on trial pitting safety which is looking at the aspects of working at height and emergency planning for trial pitting.

What do you enjoy most about being an AGS Member?
Being part of the Health and Safety Working Group provides a valuable opportunity to raise issues that you are grappling with and work collaboratively with knowledgeable people from across the industry.  The discussion is frank and informed with the aim of coming to a consensus and writing guidance to share.

What do you find beneficial about being an AGS Member?
AGS provides access to a welcoming forum where issues can be raised and discussed with the collective aim of improving the industry.  I also find the publications cover a range of issues and are useful resource – particularly the loss prevention alerts and guidance.

Why do you feel the AGS is important to the industry?
The AGS aims to improve many aspects of the industry through guidance and working group initiatives.  Best practice is developed and shared throughout the industry.  As a trade association it’s able to cover a wider membership than professional institutions and so is more representative of our industry.

What changes would you like to see implemented in the geotechnical industry?
I’m always disappointed when an interview candidate tells me that they do not know what the Construction Design and Management Regulations are and how they apply to ground investigation.  I would like to see a better understanding and the consistent implementation of the Regs across the industry.  There are significant benefits to health and safety in the field if there is consideration of health and safety and rigorous planning at the design stage.
