ABOUT THE AGS

Chair’s Foreword With the weather finally starting to show signs of improving, the summer looks set to get into full swing for the UK geotechnical and geoenvironmental industries.

For those of our readers who are regularly out on site, be sure to make the most of the weather while it lasts, and those of use who are more often confined to the office... business as usual!

‘Safety in Mind’. Tickets for this are now available but are selling fast, so get in touch to avoid missing out.

Work continues to trundle along nicely for many of our members and our Working Groups are, as always, hard at work. The Contaminated Land and Laboratory Working Groups are due to meet again at Geotechnica 2019 where I’m sure more productive discussions will be taking place. The AGS will also be exhibiting at Geotechnica, so if you are at the event be sure to say hello to our representatives there!

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.

In this issue of the magazine, we have insightful entries focussed on health and safety, including a look at the AGS Health & Safety Working Group’s latest conference titled 2

Magazine

Our cover article focusses on the contentious practice of trial pitting and asks whether it still has a place in 2019’s GI fieldwork. In addition we have a further discussion on practical guidance for managing and working with asbestos on site.

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.

The Association of Geotechnical and Geoenvironmental Specialists (AGS) is a nonprofit making trade association established to improve the profile and quality of geotechnical and geoenvironmental engineering.

News in Short Sampling soils for determination of VOCs The Draft for Public Comment (DPC) of BS 10176: Taking soil samples for determination of volatile organic compounds (VOCs) — Specification is expected to be available for comment from 1 July.

This new standard is intended to raise the reliability of sampling soils for determination of VOCs in the UK by introducing methods in common use in other countries including Australia and the United States for over twenty years. Its introduction will have profound impact on how companies carry out sampling for VOCs and require close cooperation between those carrying out field work and analytical laboratories. It has been known for decades that the methods commonly used in the UK do not provide reliable results and can lead to loss of VOCs during sampling and consequentially underestimation of potential risks to humans and other receptors.

BS10176 will be a standard specification which means that it requirements must be closely followed to claim compliance. It thus differs from other standards such as BS 10175 and the BS ISO 18400 series which provide guidance and permit, and indeed rely on, the user using their judgement when applying them.

Laboratories are required to provide preprepared sample containers prepared to the

4

Magazine

specification provided in the standard and these are to be used in the field in strict accordance with the procedures described in the standard.

Samples must be transported to the analytical laboratory in strict accordance with the prescribed method.

It is expected that in future any VOC results not obtained in accordance with BS 10176 could be rejected by assessors and regulators.

It is essential, because of the potentially significant impact on how ground investigations are carried out, that potential users including laboratories properly scrutinise the draft standard and raise any issues they consider important using the BSI commenting system which is expected to be live from 1 July to 31 August (use link - https:// standardsdevelopment.bsigroup.com/ projects/2018-01305 ). Copies of the draft standard are available to AGS members from AGS. The Drafting Panel for the new standard is chaired by Geraint Williams of ALS (geraint. williams@alsglobal.com), a member of the AGS CLWG and AGS laboratories group. Mike Smith, a member of the CLWG, is also on the drafting panel.

Article contributed by Mike Smith M A Smith Environmental Consultancy

Draft BS 10176 - Scope This British Standard specifies methods for taking soil samples for the determination of volatile organic compounds (VOCs) so as to minimize the possible loss of VOCs to atmosphere during and after sample collection.

Two principal ways of taking samples for VOC determination are specified: a)

a small intact core sealed to prevent loss of VOCs is taken and sent to the laboratory; and

b)

a small portion of material taken with a coring device is immediately placed in water or a preservative (e.g. methanol or sodium hydrogen sulfate) in a subsequently sealed vial to be sent to the laboratory.

The methanol immersion method described amplifies the guidance in BS EN ISO 15009, BS EN ISO 16558-1, BS ISO 18512 and BS ISO 22155 about this method and is intended to be followed in preference to the briefer descriptions in these four standards.

NOTE 1 This standard uses the term “soil” to refer to “soil and soil materials” as defined BS ISO 11074:2015, 7.4.16, although the procedures specified might not be applicable to certain coarse soils and rocks (see Figure 1 and 6.2).

NOTE 2 The methods described can be applied at the sampling location, in an on-site facility or at an off-site facility. In all three cases, the sample is then sent to the analytical laboratory. It is assumed that the overall site investigation is carried out in accordance with BS 10175 and that the sampling strategy is developed in accordance with BS10175 and BS ISO 18400-104.

NOTE 3 The sampling methods described are suitable for use in connection with, amongst others, the analytical methods described in: •

BS EN ISO 15009: Gas chromatographic determination of the content of volatile aromatic hydrocarbons, naphthalene and volatile halogenated hydrocarbons – Purge-and-trap method with thermal desorption;

•

BS EN SO 16558-1: Risk–based petroleum hydrocarbons Determination of aliphatic and aromatic fractions of volatile petroleum hydrocarbons using gas chromatography (static headspace method);

•

BS EN ISO 22155: Gas chromatographic determination of volatile aromatic and halogenated hydrocarbons and selected ethers – Static headspace method.

Environment Agency publishes reformed land contamination guidance

•

•

The Environment Agency (EA) has published an update to the Model procedures for the management of land contamination (CLR11).

•

The updated online guidance is called: Land contamination: risk management (LCRM).

•

The EA is looking for feedback on the technical content and structure for a period of 6 months.

Details of how to respond will be included in the guide.

•

CLR11 was introduced as a research document in 2004. It soon became the principal guidance for managing the risks from land contamination. It has never been updated. CLR11 was archived from GOV.UK in 2016 as part of the smarter guidance project. Archived content can be used for historical reference but it does not represent official EA or government guidance it cannot be used or relied upon as such. CLR11 is too significant, widely used and referenced to leave in the National Archive.

•

•

the EA must meet – it must be: accessible for people with disabilities - for example, be usable with assistive technology like screen readers navigable, concise, clear and understandable to all is web-based, easier to manage, maintain and keep up to date is now more user focussed, shorter and easier to understand is clear on what you have to do and where to find out more – the EA has retained the same referencing system as part 3 of CLR11, for example INFO-RA1 has to be aimed at people that might be doing this for the first time as well as experienced professionals is available online to use on all devices (laptop, mobile phone, tablet)

The technical language, terminology and content has been updated, explained and retained where necessary. Repetition and general background information has been removed so that the EA can meet GOV.UK publishing requirements.

Reformed content

The remediation process has been improved.

The emphasis is now on developing and producing a single remediation strategy.

The EA has developed the reformed content based on the principles of CLR11. The scope, purpose and the framework of CLR11 remains the same. The reformed content: • represents up-to-date government guidance on land contamination risk management and is fully compliant to be published on GOV.UK • complies with new accessibility laws that

To accommodate this, some of the latter stages and tiers have been revised and reordered.

Stage 2 now focusses on options appraisal whereas stage 3 is all about remediation and verification. This does not impact upon: • the framework and purpose introduced by CLR11 • any ongoing or planned land contamination projects

6

Magazine

LCRM was produced as a solution to CLR11 being archived. CLR11 will be permanently withdrawn after the feedback. This will avoid any confusion over which guidance to use.

The EA is actively seeking feedback so that the new guidance is acceptable to both industry and regulators.

LCRM will represent the latest EA guidance on land contamination and it’s what they expect people to use.

where trenches are required to provide more detailed interpretation of the stratigraphy or underground service identification and mapping, these are often undertaken by hand with or without machine assistance. Vac-Ex technology has also been used by the industry to excavate trial pits and trenches.

Trial pitting is seen as an economically advantageous investigation tool which enables a fair spread of exploratory points to be undertaken within a typical working day. In addition, trial pitting facilitates a wide variety of in-situ tests, for example Hand Shear Vanes, California Bearing Ratio (CBR) tests, Plate Load tests and Infiltration tests in accordance with Building Research Establishment (BRE) Digest 365 Publication (2016).

preparation, excavation, sampling, logging and backfilling must be planned and a suitable and sufficient site-specific risk assessment made, contributing then to a method statement.

However, consider this: with the Work at Height Regulations (2005), any excavation which has the potential for a person to fall is classed as working from height and, therefore, requires measures to be put in place in accordance with a specified hierarchy (while considering “SFARP”) to comply. Whilst injury can be caused from a fall from any height, a trial pit which is excavated to depths often in excess of 3m can pose a significant risk of injury should an operative fall into the excavation.

Additionally, the Construction Design and Management With a better awareness of All trial pitting (CDM) Regulations health and safety risk within (2015) were amended activities including our industry over the past and now identify ground site preparation, decade or so should we not, investigation as an integral excavation, sampling, however, ask the question part of the construction whether trial pitting is still logging and backfilling activities.

a decision tool on the risk against the cost and availability of technology to control it.

The HSE, in investigation and prosecution, make a computation in which the quantum of risk is placed on one scale and compared with the sacrifice involved in the measures necessary for averting the risk (whether in money, time or trouble) on the other scale. The legal test would be that measures which are disproportionate (or grossly disproportionate) would not be SFARP.

Furthermore, Regulation 22 (Part 1) of the CDM Regulation states that “All practicable steps must be taken to prevent danger to any person, including, where necessary, the provision of supports or battering, to ensure that; no excavation or part of an excavation collapses; no material forming the walls or roof of, or adjacent to, any excavation is dislodged or falls; and no person is buried or trapped in an excavation by material which is dislodged or falls”.

All trial pitting activities including site

Therefore, all excavations require an

assessment to be made of the stability of the excavation prior to commencing the dig and during the dig. These risk assessments should consider factors such as influence of the excavation method, ground conditions, buried services, obstructions, groundwater level, water strikes, contamination etc. An initial risk assessment can be produced to reflect the general approach but inevitably the trial pitting supervisor/logger will need to carry out dynamic, sometimes called “point of work�, risk assessments and where these necessitate or identify significant changes to the risk or methodology it should be documented.

However, as trial pitting work is often undertaken by graduates or technicians, can employers be sure that these individuals possess the required knowledge, training and experience to meet sufficient competency requirements or have the ability to make these assessments and informed decisions ?

When detailed logging (i.e. service identification, detailed fabric logging, scan lines or assessment of slip planes) is required, due consideration should be taken to the necessity of entering the trial pit/trench.

Where the designer determines that entry is essential, the Contractor must ensure that the excavations are sufficiently shored or the excavation sides battered back or benched to reduce the height of exposed material and potential collapse. Due consideration should also be taken by the Client to allow sufficient time and resources (money) to develop this safe system of work, to carry out any additional training requirements and for the actual work.

In addition, these type of trial pits should be located to provide sufficient working room for the plant which will be required for the installation and maintenance of the support system and spoil. As these types of works may be of a longer duration than typical trial pits, physical barriers such as fencing may be required which adds additional costs and time.

work, should be mandatory for all excavations.

However, the main advantage of trial pitting is to provide a quick and easy way to view the stratigraphy and close up inspection of the pit is necessary to obtain the desired results.

Judgements on the required controls under the Work at Height regulations are however to be determined “SFARP”.

The current AGS Guidance on safe excavation of trial pits suggests a number of control measures such as the supervisor/logger should approach and stand at the opposite narrow end of the open pit to the machine, , arisings should be placed a minimum of one metre from the pit edge, and other controls.

However, the industry, and associated industries who undertake not dissimilar construction activities, can still not agree on the approach to controlling the risk of working at height when trial pitting or even whether it is a significant risk in the first place.

When trial pits are part of a more typical ground investigation and require standard logging, in-situ testing and sampling the designer and contractor The principal arguments for should consider carefully The principal the requirement to approach whether any entry is required arguments for open pits is to observe the whatever the depth. The the requirement to formation of the ground AGS promotes an approach approach open pits is to and groundwater in situ, which does not require entry accurately measure stratum and therefore, the risk of observe the formation boundaries, water strikes, injury through collapse and of the ground and final depth and to take subsequent burial is reduced. groundwater in situ, photographs.

can be safely carried out or when works should stop and be re-assessed.

The MARGI course has been collaboratively developed, after extensive consultation with key stakeholders within the UK GI sector, to provide definitive industry guidance on the safe investigation of land contaminated, or potentially contaminated with, asbestos and ACMs. The course is aimed at planners, designers, managers, supervisors and on-site operatives and engineers who are likely to encounter and work with asbestos in soil as part of a ground investigation.

There are a number of asbestos courses in the market however they tend to be generic in content or worse, cater for other disciplines within the construction industry such as those carrying out refurbishment of existing buildings or repair work. The MARGI course has been designed for the ground investigation industry and includes an asbestos awareness section which deals specifically with how ACMs might appear in soils as well as where they might be found in buildings. The course acknowledges the unique and specific circumstances regarding potential contact with asbestos in the geotechnical industry. Key elements of the course include: An overview of legislation, the Risk Assessment and Plan of Work, Awareness for Ground Investigation workers, Non Licensed Work together with

practicals, protocols and a final assessment. to determine in a measurable way that delegates have gained appropriate knowledge, information and undergone sufficient training.

It is hoped that the new MARGI course can provide contractors with the means to continue working safely in appropriate situations, whilst granting clients peace of mind that if asbestos is encountered, protocols are in place to allow this to happen.

Interested in Equipe Training’s new MARGI course but would like more details?

Equipe will be offering “30-Minute Training Tasters” at Geotechnica 2019, held at the Warwickshire Event Centre on 10th & 11th July 2019. The Training Tasters will include the MARGI course, amongst a number of Equipe’s other courses.

AGS Review and Position Statement:

COVER SYSTEMS FOR LAND REGENERATION Thickness Design of Cover Systems for Contaminated Land: BRE/AGS/NHBC: 2004

S

tarting in 2017, the AGS Contaminated Land Working Group (AGS CLWG) undertook a review of the 2004 BRE/ AGS cover systems document to determine: a) if it was still fit for purpose given current

regulatory practice and guidance, b) what awareness of it there was within

the industry and with regulators, c) how much it was being used and

accepted by regulators as evidence, d) what was current general practice, e) if the document and software required updating, f) if it might be applicable or adaptable for

sites with trace levels of asbestos.

As part of this review, several questionnaires were forwarded to regulators and private industry practitioners and awareness was raised at several industry events as well as within the various AGS working groups. In conclusion the results of this review can be summarised as follows: The document is still considered technically fit for purpose, though the fact that it specifically excludes considerations of the emplacement of break layers and water table movements somewhat limits its applicability under current practice at present. That it has not been updated or reviewed since it was published in 2004, and whilst still available is quite expensive, also probably somewhat limits its

use by regulators or practitioners.

The document has suffered from a general change in practice since it was first published and perhaps more importantly a change in the way waste is currently defined and perceived in practice during developments. This is (in part) due to regulatory waste changes and interpretations as well as changes in CDM. This is seen as being two-fold in practice, firstly in that the placement of materials from off-site as cover can now potentially be considered a de-facto waste action. Secondly, the technical mixing of potentially contaminated materials in situ with uncontaminated material is contraindicated by current guidance, being seen as potentially “diluting� the contaminants in the underlying materials. This paradox, since the underlying material is probably not technically a waste per se, has certainly in part limited the uptake of this methodology by both practitioners and regulators.

In addition, the responses clearly indicated that many practitioners and regulators were unaware of this document and its potential uses, possibly due to institutional loss of knowledge and experience over time since publication, as well as changes in general contaminated land and waste practice. In addition, it would appear that not many practitioners were presenting such evidence or systems on behalf of clients or developers, probably for essentially the same reasons.

It was noted in the responses that many (especially the general regulatory trend regulators now default to generic requirements towards the use of generic depths and break for cover systems. The usual default being layers) probably do not justify the associated 600mm or “Two Spades depth” and usually costs of doing so at this time. overlying a break layer. This later element In conclusion, the basic science is still was seen by most regulators and some considered very sound, and the document practitioners as being more effective, acceptable and risk averse in that a break layer would benefit from a wider awareness in the community and amongst regulators were it provides added security, i.e. by providing an not for the tendency towards the more risk obvious pathway linkage break. Such actions averse inclusion of break layers and standard also avoid having to consider potential mixing depths.

My father inspired me to be involved in our industry. I remember travelling to nearby Wirral where he pointed out interesting geological features including the ‘Red Rocks’ at Hoylake.

What does a typical day entail?

I spend lots of time supporting my teams, through technical review, dealing with clients’ challenges and troubleshooting when issues inevitably arise. Training and mentoring colleagues is important and also the most rewarding aspect of my job.

Are there any projects which you’re particularly proud to have been a part of?

I spent the formative years of my career carrying out intrusive investigation work for McAlpine on a major gas pipeline project in the North West which was an excellent grounding for anyone starting out in our industry. I’ve been fortunate enough to be involved in the largest land

contamination projects in the UK. I’ve been involved in projects in the Occupied Palestinian Territories, Afghanistan, Kuwait, Ivory Coast, and Nigeria. I was in Iraq recently training those who are managing the investigation and remediation of sites that experienced widespread destruction from sabotage and looting by Islamic State.

The impacts of war in eastern Mosul are so extensive that much of the old city has essentially been destroyed.

It is a privilege to be part of reconstruction efforts in conflict affected areas of the world.

What are the most challenging aspects of your role?

Being away from my family – I spent a month in West Africa when my daughter was first born. She is now eight so probably won’t notice if I spent six months away from home!

“

AGS provides its members with a real voice within industry – we are active on the National Brownfield Forum, we are represented on the Phase 2 Category 4 Screening Level Project and are involved in updating the Guiding Principles; our membership includes the Environment Agency and the National House Building Council. We probably don’t appreciate how respected and influential the AGS actually is. I suspect this will only increase as focus is shifting more towards industry-led guidance.

What changes would you like to see implemented in the geotechnical industry?

Like most of us, I’d like to see government implement a truly brownfield first policy. Our sector is worth £1 billion a year and employs almost 10,000 people. The housing crisis is one of the UK’s greatest challenges and brownfield development is key to solving it. No surprise that AGS is at the forefront of highlighting these challenges and making positive steps to address them.

AGS Working Group Focus

Contaminated Land Overview 2. AGS Guidelines 4. Next CLWG Meeting to Good Practice in Geoenvironmental Ground In their next meeting, which is taking place in July, the Investigation

Vivien Dent of RSK, the leader of the Contaminated Land Working Group, has provided an update on the top issues the Contaminated Land Working Group discussed in their recent meeting which took place in May 2019.

1. Updating the AGS Asbestos in Ground Investigation Guidance This document was issued as interim guidance in February 2013. Since this time, there have been several publications and guidance documents published. The guidance is therefore possibly out of date and is being revised. The aim of the guidance is for people to know how to work safely when they encounter asbestos. The AGS Asbestos in Ground Investigation Guidance is currently in final draft and is being peer reviewed by the AGS Contaminated Land WG, along with the AGS Safety WG and AGS Laboratories WG.

An opinion piece by Chris Swainston of Soils Limited on AGS Guidelines to Ground Practice in Geoenvironmental Ground Investigation was featured in the May 2019 issue of the AGS Magazine and can be viewed on the AGS website. The Contaminated Land WG are considering the possibility of creating a ‘road map’ of documents. The AGS aim to promote good practice - as Chris mentioned in his article - if you stacked the relevant documents on top of each other, the guidance alone would probably reach to your waist. As there is so much information out there – how do you know what is relevant? It is important that AGS members know which guidance to follow and where to find the guidance.

3. ERES Code Review A working group has been established to review ERES Codes. The ERES Codes are being reviewed as it is important to have consistent data. For example, so there are not two or more codes for the same determinant.

Contaminated Land Working Group will be looking at the Environment Agency’s online guidance; Land Contamination: Risk Management (LCRM) which is an update to the Model Procedures for the Management of Land Contamination (CLR11), with the aim of providing feedback to the Environment Agency on behalf of the AGS.

Feedback on issues The Contaminated Land Working Group would like AGS members to feedback to the group about any issues they are struggling with and if there are any issues which they would like to group to investigate. If you do have any issues for the Contaminated Land Working Group to discuss, please email ags@ags. org.uk.

If you wish to attend AGS Contaminated Land Working Group meetings, please contact the AGS Secretariat by emailing ags@ags.org.uk.
