Here is the additional information mentioned above.

Description of raw data

Raw data comes in many forms and it is crucial to understand what sort of data you have.

The Decision Tree helps you at every step; here is an example from one of its pages.

By way of background, data can be described as either discrete or continuous.

You may have data of a “Yes or No” type, where only one of two possibilities is recorded. For example: Was the SPT “N” value greater than or less than 25. Yes or No? This is an example of “discrete data”.

There is always a clear title for each activity – so

The description of raw data

Then background is provided

“Raw data is collected and comes in many different forms. Two types of data are described below, discrete and continuous.”

Then one or more examples are given – this one, for discrete data, is for clinicians.

The data can be of a yes – no type where only one of two possibilities for a number of patients is recorded, for example has the patient high blood sugar levels or not? Yes or No?

For ground engineers such an example could be “Does the value for cadmium exceed the the recommended threshold? Yes or No?

The decision tree explains every term in laymen’s language, so you don’t need to be a statistician to understand them. All the examples in the decision tree come from medicine because the tree was developed for medics – but the statistical methods they illustrate can be applied to any subject, not just medicine.

Graphical descriptors

Three commonly used graphical tools used to describe statistical data are shown here. A bar chart, a pie chart and a box plot.

In the decision tree these and other graphical tools are described and the technical terms used in connection with them are explained.

But as you may have guessed, not every graphical tool can be used for any data set; here the decision tree helps you decide which graphical method is correct to use.

Data sets are described in quantitative terms, where each of the terms used is uniquely defined. More often than not both graphical and quantitative term types of description are required.

Tabular description tools

Tabular tools describe your data set in quantitative terms such as data tables and summaries, frequency, average and mode that are precisely defined.

This slide shows an extract from one page of the decision tree which defines, tables, summaries and frequencies.

Each of the terms mentioned under summaries on this slide like frequency, relative frequency, mode, mean and so forth is described and illustrated on this page of the decision tree.

Worked examples are also included to show you how to find the appropriate values for your data set by showing you how these values have been calculated step by step.

The next slide will take you to the home page of the website which contains the decision tree in its membership area.

About the decision tree

As mentioned before the Decision Tree was designed for medics but can be used for all subjects including geotechnics.

Recent changes to Landfill Tax – Implications and potential liabilities for AGS members

- by
Tags: Featured

Background

The HMRC Excise Notice LFT1 (‘LFT1’ or ‘notice’) deals with requirements under Landfill Tax legislation. The notice is primarily for operators of landfill sites, but is also relevant to waste producers and others involved in the waste management industry. The notice applies to England and Northern Ireland and is usually updated annually, generally to report the annual rise in the rates of landfill tax.

The April 2018 version replaced the 2017 version and contained a new clause with potential implications for several parties, including AGS members. It should be noted that the April 2018 version has subsequently been replaced by LFT1: November 2018, which contained further minor updates including the annual rise in the rates of landfill tax.  This advice note focusses predominantly on the changes introduced in the April 2018 version but accurately reflects the increases in landfill tax rates introduced in the November 2018 version.

The 2018 update

Section 24 of the LFT1 (a new clause added in 2018) presented amendments to the definition of a taxable disposal at authorised landfill sites and disposals made at unauthorised sites.  It states that Landfill Tax is now due on disposals of material at unauthorised sites in England and Northern Ireland; this also applies to disposals prior to 1st April 2018 that are still on site from the 1st April 2018.  An unauthorised site is any site, or area of land, that should have authorisation (a Permit or Licence) from either the Environment Agency or the Northern Ireland Environment Agency, but does not.

Section 24.4 of the notice states that the following people may be jointly and severally liable for the tax:

  • The person who makes the disposal
  • Any person who knowingly causes or knowingly facilitates the disposal to be made

When determining the persons who may have knowingly caused or knowingly permitted the disposal to be made, the following persons may be considered, but not limited to:

  • The waste broker or dealer involved with the disposal
  • The waste haulier involved in the transport of the waste to the unauthorised site
  • The landowner
  • The waste producer
  • Any company officer

Slightly different legislation applies in England and Wales.  In England, the landfill tax for unauthorised deposits is applied at the standard rate, which is currently £88.95/tonne (£91.35 from 1 April 2019).  However, in Wales a higher charge of £133.45/tonne (£137.00/tonne from 1 April 2019) applies for unauthorised deposits of waste.  The lower rate of £2.80/tonne (£2.90/tonne from 1 April 2019) for qualifying materials does not apply to disposals made at unauthorised sites.

HMRC can also charge an additional penalty of 100% of the landfill tax due.  If they decide to prosecute a criminal offence, an unlimited fine and/or up to 7 years in prison are possible.  These would be in addition to any costs that might apply to remedy the unauthorised disposal if required by the Environment Agency (EA) and any fines or penalties they may look to impose.

Implications

There are reports of developers who dispose of spoil arisings from construction sites at unauthorised sites (i.e. to land without a Permit/ Licence, without an exemption or which are not in compliance with the CL:AIRE DoWCoP).  The implications of Clause 24.4 for AGS members are that, if they are considered to have facilitated any such disposal, they could be jointly or severally liable for the landfill tax that should have been paid along with the HMRC fine.

HMRC and the EA are working together to actively find unregulated disposal sites and there have already been direct approaches to AGS members from HMRC/EA asking for proof to be provided of compliance with the DoWCoP.  The regularity of prosecutions and the value of fines is increasing, with enforcement and prosecution replacing the consultative approach previously adopted by the EA.  Chubb report that the average fine by the EA has increased dramatically from £5,000 in 2000 to £178,000 in 2017.

To illustrate the point, a successful 2017 prosecution for depositing 3,920 tonnes of waste on land in breach of a waste exemption attracted a fine of £19,500.  Under the further sanctions outlined above (assuming a criminal prosecution is not pursued), HMRC could potentially apply for £350,000 of landfill tax due and a further fine of £350,000 (100% matching of the landfill tax amount).  In addition, the site owner may be instructed to remediate the site and may be liable for associated EA penalties or fines.

Recommendations

A person can show that they did not knowingly cause or knowingly permit a disposal at an unauthorised site if they take all reasonable steps to ensure that a disposal at an unauthorised site does not happen.  HMRC intend to consider the criteria set out in the Defra Waste Duty of Care Code of Practice in determining such “reasonable steps” (some of which are more relevant to AGS members than others).  HMRC expect a person to:

  • make reasonable checks that the next waste holder is authorised to take the waste material
  • ask the next waste holder where they are going to take the material and obtain proof if possible
  • provide an accurate description of the material when it is transferred to another person
  • as a company director or partner, be directly engaged or responsible for decisions made regarding the disposals of material by that business
  • as a landowner, ensure that any lease or rental agreements state clearly what the premises or land may or may not be used for
  • as a corporate body, to include risk management procedures within your company’s risk assessment to take steps to prevent criminal facilitation of Landfill Tax evasion through your business

In terms of the appropriate application of the DoWCoP, six requirements must be met to ensure that materials management complies and waste licensing regulations are not breached:

  • Protection of human health and environment
  • Suitability of material for its intended use
  • Certainty of material use
  • Quantity of material for use is appropriate
  • Verification reporting
  • Competence of practitioners

Although the verification report has always been an essential requirement of the DoWCoP, it has often been overlooked after the Material Management Plan has been prepared and Qualified Person (QP) declaration submitted.  Under the current version of the DoWCoP, the verification report is not required to be submitted to the EA nor reviewed by the QP.  However, this is likely to change in the upcoming Version 3 of the DoWCoP.  As a step in this direction, the current QP declaration form now asks for the identity of the organisation and individual(s) with responsibility for producing the verification report as well as an estimated production date as a reminder that these are required.

Data, Technology and Engineering Geology – What does the future hold?

Tags: Featured

State of play

Figure 1 – Overview of the Engineering Geology Life Cycle and data collected throughout

As it stands the engineering geology life cycle (Figure 1) feels a bit disconnected, especially when it comes to passing data through each phase of the project. This leads to data being lost at each stage of the cycle and ultimately the project never benefiting from all the potential information available (Figure 2). This is somewhat understandable given the number of different parties involved in the collection, processing and interpretation of data and each party focused on different phases of the life cycle. However, this should not be used as an excuse. The lack of technological advancements across the construction industry has also left us lagging behind other sectors of the economy (Figure 3).

Figure 2 – Schematic of the current and potential journey of information through the different phases of a typical engineering geology project

Figure 3 – Productivity of the construction industry compared with services, manufacturing and the whole economy.

Source: Taken from McKinsey Global Institute (2017)

The creation of the AGS data format in 1991 was a significant step to improving data transfer in the ground engineering industry. However, there have been limited further strides forward since then and we are approaching the 30-year anniversary since its introduction. So, what is the solution?

Data at the centre

Figure 4 – The engineering life cycle with data at the centre

Firstly, we must put data at the centre of the engineering geology life cycle (Figure 4) and map out how data will move through the life cycle and the supply chain. By doing this we ensure data is transferred in the most efficient way possible. This must happen right at the start of the project.

The emergence of the Common Data Environment (CDE) facilitates this. The CDE is not new but its application is still limited to a select number of projects, despite the obvious benefits. For one, it provides a single source of truth that all parties can trust in. This is essential for large infrastructure projects such as HS2, Heathrow and Thames Tideway that have tens of thousands of documents across multiple disciplines.  A CDE combined with a clear workflow also encourages collaboration and early sharing of information allowing engineering geologists and designers to make more informed decisions earlier in the project life cycle. For this to work we must also ensure there is interoperability between software and a well-defined data taxonomy is agreed across the industry (i.e. an AGS approach across the whole life cycle).

Where can technology assist?

It is important that any new technology has a clear tangible benefit. This might be increasing the accuracy of analysis, providing new data, improving efficiency of a task, facilitating better communication between the supply chain or improving safety. By identifying this ‘added value’ at the start of the project and reviewing it throughout ensures that technology is not used just for the sake of using it – something that potentially risks undermining the technology that will assist.

Figure 5 – Snapshot of Leapfrog model of Thames Tideway East shaft created to help visualize how potential fractures intersect with the shaft

Technologies that are already showing ‘added value’ include:

  1. Drones – Benefits include surveying large areas quickly, accessing places that are too dangerous for humans to access and ability to generate ‘intelligent’ 3D models of sites that open the door to ‘unlimited’ site visits;
  2. 3D Ground Modelling – Allows better visualisation of ground related risks to help ground engineers make more informed decisions. It also acts as a powerful communication tool to communicate ground risks to clients and other stakeholders (Figure 5); and
  3. Smart Infrastructure – Enables real-time asset data to be obtained that can assist design verification, early identification of potential problems and a predictive maintenance approach.

Artificial intelligence (AI) also has huge potential to assist the ground engineering industry. Yes, the ground is notoriously unpredictable making it difficult for AI to make reliable predictions on ground conditions or parameters. But based on historic data, AI could produce generative models that ground engineers could test and revise following targeted ground investigations.

Challenges

We should not shy away from the fact that embracing technology will bring its own challenges.

Four of the key challenges are:

  1. Upskilling of the industry;
  2. Validation of new software;
  3. Industry standards; and
  4. Industry culture.

Firstly, we must ensure that people are adequately trained in any new software tools and processes that are available (e.g. borehole logging using tablets). This is no easy task and ignites the debate as to whether the training responsibility lies with the industry or university. What is for sure though is that without the necessary skills to use and interpret the results from new technology we won’t be able to achieve nearly as much as we could. Geologists must also not forget their core skills of critical thinking and interpreting the subsurface.

Secondly, we must ensure new technology is robust and can be trusted. It is very easy to produce an all singing and dancing 3D model, but it must also make geological sense. Professor Fookes hinted at this in the First Glossop Lecture where he stated, “Technical innovation must stand the test of time in order to prove its worth”. We must also ensure that new processes and technology are also incorporated into existing industry standards or if required new standards developed.

The most difficult challenge of all, is the cultural transformation of the industry. Currently the value of data is not well enough understood, particularly among clients. As it is the clients who hold the purse strings, it is them who can lead the transformation. But it is equally the job of designers and contractors to share success stories and highlight the benefits that technology and effective information management can bring. This is particularly important if benefits are not realised until further down the asset life cycle. It is also crucial that the whole supply chain is singing off the same hymn sheet.

Where do we go from here?

Whether it is providing additional tools to better equip the ground engineer or creating cost savings for the client, the benefits of embracing  new technologies and effective information management are clear. What we must do is to be better at sharing these benefits and success stories, particularly with clients.

Yes, there will be challenges along the way, particularly winning the hearts and minds of everyone in the industry but these are worth overcoming. We must remember that new technologies should make the life of an engineering geologist easier, not harder and allow us to focus on what we do best – critical thinking and interpreting the ground. It is important that these core skills are not sacrificed as these are things that technology cannot replace.

SiLC, SQP and NQMS Update: Spring 2019

- by
Tags: Featured SiLC

There are now 196 registered SiLCs. The current round of examinations (2019a) has 13 candidates and the previous round (2018b) had 14 candidates. This is somewhat more than the numbers in previous years and indicates that the register is growing and has become a recognised body of professionals who have demonstrated their capability and experience in the brownfield sector. SiLC are the awarding body for the registration of SQPs under the National Quality Mark Scheme (NQMS) and there are currently 97 SQPs.

This obviously indicates that not all SiLCs have taken the online conversion course and exam to become an SQP. You have already demonstrated your capability in order to become a SiLC. The online exam is not intended to retest this but instead is there to ensure you have the additional knowledge to be an SQP. All the information you need is in the slides that form part of the online conversion course.  You have a relatively short step to becoming an SQP.

Most of us have an interest in achieving high standards in the products we deliver to our clients and the services we provide and therefore should be using whatever means are available to us to demonstrate this high standard. The NQMS can do this. Quite a number of clients are reported to be asking for Declarations to be submitted under the NQMS, ie signed off by an SQP. However, it is acknowledged that more publicity of the scheme is needed so that the NQMS becomes more recognised with respect to its benefits. SQPs explaining the benefits of the scheme to their clients will help this.

A number of local authorities are now signposting the NQMS. A selection is presented below;

Staffordshire Local Authorities (9 local authorities) reference NQMS in their developers guide regarding competent people:

https://www.newcastle-staffs.gov.uk/sites/default/files/IMCE/Environment/EnvProc/Developers_Guide_2017.pdf

Herts & Bedfordshire and Neighbouring Authorities Contaminated Land Forum (17 local authorities) reference NQMS in their guidance regarding competent people:

https://www.hertsmere.gov.uk/Documents/04-Environment-Refuse–Recycling/Environmental-Health/Pollution-Control/Herts-and-beds-guidance-revision-2018.pdf

Worcestershire Regulatory Services reference NQMS – WRS recommend SQP appointment for expediency purposes:

http://www.worcsregservices.gov.uk/media/3261881/WRS-technical-guidance-document-for-Planning-V4.pdf

Tunbridge Wells Borough Local Plan – Contaminated Land Supplementary Planning Document – supports the NQMS for land affected by contamination as a desirable component of any work undertaken to deal with land contamination:

http://www.tunbridgewells.gov.uk/data/assets/pdf_file/0020/131708/03_Contaminated-Land-SPD_adopted-Sep-2016.pdf

One other local authority has stated that “On receipt of a report with the NQMS mark we would hope to find the review of the report to be straightforward and be able to determine it as acceptable ideally without any queries at all”. However, they go on to say that they “will not take the view that this scheme is a means to streamlining the satisfaction of conditions to the point at which a submitted report is accepted without conditions”. It should be pointed out that this is not the aim of the NQMS. Instead it is intended to raise standards and produce a quality that local authorities can rely on to enable them to utilise their resources as they think appropriate. It is hoped that many more local authorities will see the advantage to them of signposting to the NQMS.

As many will know, the Environment Agency have endorsed the scheme and the following give an indication of standard advice on planning application responses suggesting that the NQMS is used:

SiLC Affiliate Scheme      

Becoming chartered is a prerequisite to applying for SiLC Registration. Thus, those that have a specific interest in the brownfield sector and are looking to progress their careers in this direction need to plan for both becoming a full member of their chosen institution as well as becoming a SiLC. To facilitate this, the SiLC Affiliate Scheme has been launched and details are on the SiLC website (www.silc.org.uk) where there is an application guide and an application form. As indicated in the July-August 2018 edition of the AGS eMagazine, the scheme is of interest to graduates and those who have already progressed their careers beyond graduation but not yet become chartered, to work towards full membership and chartered status of a professional body with the assistance of a professional body adviser, and then progress towards SiLC/SQP registration with the assistance of a SiLC mentor. The scheme can be entered at any level. The aim is to provide an integrated process for those on the scheme with clear objectives utilising the Brownfield Skills Development Framework and an early understanding of the purpose and benefits including CPD, the NQMS and the role of an SQP.

Members of the scheme will be designated as SiLC Affiliates, each with a SiLC Affiliate number, thereby demonstrating an individual’s commitment to becoming chartered and, in due course, a SiLC. The annual membership cost of the SiLC Affiliate Scheme is £50 plus VAT and includes 20% discount on the attendance fee for the SiLC Annual Forum.

Q&A with Jim Cook

- by
Tags: Featured

 

Full Name: Eur Ing Jim Cook BSc, MSc, C Eng, C Geol, FICE, FGS

Job Title: Director

Company: Geotechnical Services Bureau Ltd

I am a both a chartered civil engineer and a chartered geologist and have worked in the geotechnical industry for over forty years both as a specialist contractor and a geotechnical consultant. I am experienced in most of the facets of geotechnical engineering including site investigation, foundation construction and geotechnical design for many different types of structures and buildings. I have substantial overseas experience particularly the Gulf States, West and East Africa, India, Sri Lanka and Hong Kong. In recent years, I have been involved in major geotechnical design and construction assignments in USA and the Caribbean.

What or who inspired you to join the geotechnical industry?

I was initially indentured as a civil engineer with a local authority in London and undertook part time education at Westminster College. After a couple of years, I joined a major civil engineering contractor, Costain, and was immediately seconded to their geotechnical company, Foundation Engineering Ltd, who undertook most forms of geotechnical engineering including site investigation, foundation construction and geotechnical design. It was with this company that I was trained in all aspects of geotechnical construction and foundation design.

What inspired me into geotechnics initially  was the lifestyle of a young engineer travelling all over the UK and working on different sites. My recollection of a structural engineering lecturer stating that “he could design a concrete and steel structure to perform as required as both had man-made  stiffnesses but a geotechnical engineer who has to deal with the ground which has no guaranteed stiffness or behaviour has major issues”. This wetted my appetite for the challenges of ground engineering.

As a young geotechnical engineer I was given responsibility to manage teams of drillers, grouters, anchorers and pilers on site and learn the “how to do” of the geotechnical contracting industry. It is from these experiences that I owe my wealth of foundation construction knowledge.

I was fortunate to work with and be guided by some of the “leading lights” in the ground engineering industry such as John Jennings, Stanley Serota and in particular Roy Wakeling.

With regards to academics, I clearly remember meeting Professor A W Bishop to find out how the Bishop Sand Sampler worked. Professor P Fookes also inadvertently raised my keen interest in geology. Professor Noel Simons of Surrey University was my key mentor who helped to further develop and enhance my geotechnical design expertise to match that of geotechnical construction, this is how I became an all-round geotechnical engineer.

What does a typical day entail?

A typical day nowadays starts with reviewing overnight emails and dealing with one or some of the following matters which may require desk studies, site visits and collaborative meetings.

  • Litigation type matters. Sometimes these can between a specialist contractor and a main contractor or an owner and contractor but all involve some aspect of ground engineering.
  • Design and Peer reviews for other consulting engineers or contractors.
  • Optioneering reviews to develop the best foundation solution at concept stage and taking this through to construction.
  • Training of young civil engineers, particularly in the areas of geotechnical and geological risk.
  • Undertaking “pro-bono” work for RoGEP, AGS or Ground Forum.

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

I am particularly proud of returning to my “roots” in London, I was involved in the Thames Barrier as a young geotechnical engineer some 40 years ago and since then have worked as a geotechnical engineer in over 30 countries on many significant projects. But I was extremely pleased to lead the Buro Happold ground engineering team that worked on the Lower Lea Valley proposal for the UK Olympic bid which then won and became the 2012 London Olympics.

In addition, I was involved at a senior level on the Arsenal Stadium, London Olympic Stadium, the refurbishment of The Cutty Sark and Emirates Cable Car which crosses the River Thames at the O2. These all posed tricky geotechnical issues which required some form of innovation. I consider that I have put something positive back into my “roots”.

Overseas I am quite proud of the basement structure which was about 18m deep with a footprint of approximately 22,500 square meters which was designed and constructed for Harvard University in Boston USA. This was arguably the largest single basement structure to be constructed on the East Coast of the USA. The ground conditions comprised Boston Blue Clay over gravel then rock close to the Charles River which, presented major challenges that were met by using European sophisticated ground investigation techniques and high quality laboratory testing provided by Massachusetts Institute of Technology.

What are the most challenging aspects of your role?

The challenges of today are quite modest compared to managing a multi-million pound geotechnical consultancy or geotechnical contracting company both of which I have been fortunate to manage. The challenges were and probably still are getting young people interested into geotechnical engineering, finding well educated graduates and training them to become innovative ground engineers.

What AGS Working Group(s) are you a Member of and what are your current focuses?

I am a member of the Senate and focus on membership issues.

I have been a long serving Treasurer and also Chairman of the AGS and was instrumental in the conception of the AGS and have over 20 years of active participation.

What do you enjoy most about being an AGS Member?

I suppose what I enjoy is the comradery which its membership provides and more so the fact that the ethos is all about raising the profile and standards in ground engineering in the UK.

What do you find beneficial about being an AGS Member?

The benefits are not only the wealth of publications that are produced which are extremely informative, and also provide sound risk advice. There is also inputting into a collaborative view on where the industry is going.

Why do you feel the AGS is important to the industry?

The AGS is now probably the major voice of the ground engineering industry and punches above its weight with clients and local authorities. It provides regular support to those business institutions such as BSi, HSE and other government agencies.

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

I would like to see more collaborative efforts from industry, academics, institutions, local authorities and government departments. Some of these organisations are still somewhat disconnected. Ground Forum continues to develop the above linkages, and I wish them well in their endeavours.

There are still many so called “engineers” offering clients ground engineering services outside of their skill and experience base.

I would like to see all ground engineering practioners becoming RoGEP registered as this will raise them to a higher level of recognition and enhance the clients’ ability to select a competent and suitably experienced ground engineer for their project.

In response to comments from industry, the working group for BS8485 have updated and released the following which can now be ordered or downloaded from BSI. Please note that this is a technical reference, can be normative and the most current version should be that cited in reports.

BS 8485:2015+A1:2019 Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings describes how to characterise sites and prevent the entry of toxic, asphyxiating or explosive ground gases. This 2019 amendment changes and clarifies:

  • The minimum gas protection points required for Buildings Type B, C and D on High and Very High gas hazard sites.
  • The assignment of gas protection points for the structural barrier for basements.
  • The criteria for membranes that can be assigned 2 gas protection points when used as a gas resistant membrane.
  • The membrane thickness test method applicable to the guidance in the code of practice.

Other industry guidance exists but none provides the same clarity on remedial solution selection.

This standard also helps you comply with Building Regulations Approved Document C: Site preparation and resistance to contaminants and moisture.

AGS Safety Working Group Update

Tags: Featured

The first AGS Safety Working Group meeting of 2019 took place on Wednesday 23rd January 2019 and the Leader of the AGS Safety Working Group, Adam Latimer of Ian Farmer Associates, has provided an update on the top issues the Safety Working Group are currently discussing.

AGS Health & Safety Conference – 21st November 2019

The AGS will be holding a conference on Health, Safety & Environmental topics on 21st November 2019 at the National Motorcycle Museum, Birmingham. The conference will include key note speakers and break-out workshops. The speaker line-up will be announced in the AGS Magazine and on the AGS website in due course. Details of the sponsorship packages can be viewed on the AGS website.

New and Updated Health and Safety Guidance

The Safety Working Group have recently published a number of guidance documents including Guidance on Slope Climbing Rigs, Manual Handling and Unexploded Ordnance. The Safety Working Group are also progressing with guidance documents on track mats and tracked plant, the H&S Risk Assessment for Ground Investigation and minimum levels of training and competence. There are plans to develop a range of topics centred around health and well-being. The creation of bespoke and clear guidance for ground engineers is a key aim of the Safety Working Group. H&S legislation can be a mine field to navigate and these concise and succinct publications offer some clarity for our members. Compliance with Health & Safety legislation is of critical importance in everything our members do and as such the AGS offers our members free and unbiased guidance on the main issues affecting our industry. AGS Guidance can be downloaded from the AGS website.

AGS Safety Articles

The AGS Safety Working Group are working to produce a number of articles on trial pitting, PAS 128 (now published), track plant, occupational health and heat stress for future issues of the AGS Magazine. Despite the guidance being free to download from the website, the AGS magazine offers an invaluable mechanism to promote the work of the AGS SWG and provide the guidance to a wider audience. The AGS is always looking at ways to raise awareness within our industry and up-to-date guidance and magazine articles are an excellent vehicle to convey our message. The AGS continues to work collaboratively with all our members and other trade association groups to improve our industry.

Possibility of a Health, Safety and Environment Awareness Workshop to Undergraduates

The AGS Safety Working Group are in the early stages of investigating the possibility of a Health, Safety and Environmental Awareness Workshop to Undergraduates. Work is ongoing to establish the current level of understanding on university geosciences courses and whether a workshop would be beneficial.

Feedback

The Safety Working Group always welcomes new members and any feedback from the membership on hot topics that they wish to raise and encourage, any near misses and incidents to be shared to the wider industry, so we can strive to making our industry safer. Please send any feedback to ags@ags.org.uk.
