ABOUT THE AGS
Chair’s Foreword Happy New Year from the AGS. We are grateful to our members for your support in 2018 and hope that all our member organisations will find 2019 to be a prosperous year. As part of the Christmas and New Year festivities we ran the very first AGS photography competition, with the results enclosed in this issue. There was a tremendous response, demonstrating the enthusiasm that our members have for the industry. The high quality of submissions was noted by the judges and we will ensure that several of the entries will be shown in future issues of the magazine. Due to the success of the competition we will be running it again in the future. A big thank you to everyone who submitted their photographs, it’s good to know that our skills extend beyond those associated with the ground. Our Working Groups have again made significant contributions to the contents of this month’s magazine, with items from our Safety, Loss Prevention and Contaminated Land groups. There is also quite

PAS 128 : The Essentials
P
AS 128 – what is it? Is it simply as a way standardising utility surveys or is it an attempt to minimise health and safety risks associated with any form of intrusive groundwork?
“
First of all – despite it being published by BSI - it is not a British Standard as we usually know it, but rather a specification for the mapping of underground utilities. Therefore, in following the standard the user can demonstrate they have followed a logical and consistent approach to gathering and recording the data, but cannot demonstrate that the approach adopted is the right one for their particular circumstances. That said, PAS 128 does state that one of its purposes is to seek to raise the quality and reliability of such surveys. Crucially Section 0.3 states ”TSA level 3 – EML only survey – is deliberately not accounted for and not included as a detection method because
8

this PAS is looking to raise the standard of detection so that in all cases a minimum of two detection techniques – ground penetrating radar (GPR) and electromagnetic location (EML) – are used.” Clearly therefore the use of a Cable Avoidance Tool (using EML) on its own, a mainstay of buried service avoidance for ground investigation in the past, is not deemed to be adequate for detection purposes. Where EML is used it should be noted that use of a Cable Avoidance Tool in conjunction with a signal generator (Genny) will often increase the reliability and capability of this technique.
Clearly therefore the use of a Cable Avoidance Tool (using EML) on its own, a mainstay of buried service avoidance for ground investigation in the past, is not deemed to be adequate for detection purposes.
PAS 128:2014 ‘Specification for underground utility detection, verification and location’, to give it its full title, identifies four types of utility survey ranging in a hierarchy from Type D to Type A with the latter providing the most detail and highest level of confidence in the
The successive levels of Survey Type C through to Type A require increasing levels of effort and therefore expense. The next level, a Type C (‘Reconnaissance’) survey, would involve a site walkover such that existing records are supported and validated by the visual inspection of physical evidence observed. In the context of ground investigation, it makes sense for this next level of survey to form part of the planning/design stage so that the exploratory hole positions and designer’s risk assessment can be updated accordingly. A Type B (Detection) survey is probably the minimum level that is appropriate to most ground investigation work whether specified by the client/consultant or not. It involves the use of geophysical techniques to detect buried services and PAS 128 suggests that Photo credit: Geotechnical Engineering Ltd the primary techniques to be used are EML position of the utilities. Generally one type will (Electro-Magnetic Locating) and GPR (Ground follow the previous with Survey Type D being a penetrating Radar). The EML technique is most precursor to Type C and so on. However, as the commonly manifested using a CAT (Cable document does not specify Avoidance Tool) various models The guidance which type of survey or level of which offer varying of confidence is appropriate levels of accuracy and recommends for any given situation, it is sophistication. The guidance that more than one therefore of little comfort recommends that more than geophysical technique to know that buried utilities one geophysical technique should always be used. searches have been ‘carried should always be used. Note out in accordance with PAS 128’ 4 of the PAS states that “No unless the type of Survey used is detection technique can appropriate to the situation in hand. However detect every type of underground utility in that is not to say that the type of survey every location” and hence the possibility of adopted is optional as PAS128 does state that undetected services being present must be this should be decided on a case by case basis recognised even when multiple geophysical with all parties, based on the level of risk at a techniques are adopted.

different quality levels are obtained. For example a Type B survey, a B2 quality level reflects an accuracy 250mm or 40% of detected depth, whereas a B1 quality is 150mm or 15% detected depth. However in the context of ground investigation the precise location and depth is only important in so far as this helps to prevent damage occurring during the investigation process.
otherwise.
Physically verifying every service may not always be appropriate in the context of GI works – however there will always remain uncertainty over the location of any buried service which has not been subject to verification. In order to reduce the risk as low as reasonably practicable with regard to avoiding danger from underground services, Clearly, where services are designers should carefully present, the only way to get consider specifying as a 100% confidence of a service minimum a Type B PAS 128 Hand digging type, location and depth is survey as part of the GI.

Variability in Asbestos Analysis in Soil
T
here have been efforts to improve the analysis for asbestos in the last ten years: Analysis methods changed significantly around 2011-2014 with more scrutiny from UKAS. Prior to this, laboratories tended to offer a standalone visual screen to determine if asbestos containing material was present in the sample, but this would only cover pieces of asbestos containing material (ACM) and fibre bundles, and would not include small fragments or free fibres.
Improvements in methods A Blue Book method has been developed and while still in draft the basic methodology has generally been adopted by the majority of laboratories across the UK. The Blue Book method includes identification of asbestos fibres under a microscope. This analysis is a time intensive process using analysts with a high level of skill and training to identify, count and measure fibres on the filters examined under the microscope.
Remaining Variability
In the light of these comments Despite these we carried out a review to try to determine the changes there sources of variability across have been a number a number of laboratories. of comments on the As part of this, we spoke to variability of soil six laboratories and asked analysis for asbestos... about their processes.
“
Despite these changes there have been a number of comments on the variability of soil analysis for asbestos including an article in Geoenvironmental Matters which states that “Certainly, it has been rumoured that remediation contractors have come to know which laboratories quote “find asbestos” and which ones don’t.”[1]

The detailed Stage 2 analysis comprises inspection of a representative subsample under a stereo microscope...
For this second step of the screen we did encounter wide variation in mass of the subsample ranging from 20g to 100g and the amount to be used is not specified in the standard. There is no detection limit on the asbestos screen. It, however, seems obvious that a laboratory screening a larger subsample is likely to have a lower detection limit than a laboratory screening a smaller subsample but also may have higher costs as the process is more time intensive.
Further Quantification Stage 2 in the Blue Book method is gravimetric analysis. This involves identification and removal of visible ACMs for gravimetric analysis and subsequent detailed Stage 2 analysis. The detailed Stage 2 analysis
14
Magazine
comprises inspection of a representative sub-sample under a stereo microscope and the removal of smaller ACM fragments and fibre bundles for identification and gravimetric analysis to determine asbestos percentage by weight.
We note that typically the laboratories tended to use a similar mass of sub-sample for Stage 2 gravimetric analysis to that used in the Stage 1 screening. Interestingly the latest draft of Blue Book sets out that a 20g to 50g subsample should be taken forward for Stage 2. Those who have previously taken a larger sub-sample could be at a disadvantage in terms of technical compliance with the Blue Book method and analysis cost, even though their method has a greater chance of finding asbestos. The latest draft of the Blue Book may thus push some laboratories towards a lower sensitivity screening and gravimetric quantification method.

Summary
[1] Is the quantification of Asbestos in Soils still a lottery?
As the CIRIA guidance C733 on Asbestos in soil and made ground states, it is important that asbestos analysis is done well. In the light of the above, we recommend that those procuring laboratory analysis for screening of asbestos in soils using accredited laboratories should discuss the sample preparation and sub-sampling with their laboratory to

This is akin to a Statute or Law. Failure to comply could have serious repercussions. It could mean some form of disciplinary process, maybe being “struck off” or actual criminal prosecution if human life, the environment, property, etc. is put in jeopardy. Defining Professionalism is trickier but yields the following salient items: 1. Specialised Knowledge. Professionals are known for their knowledge in a specified field; 2. Competent. Professionals get the job done; 3. Honesty, Integrity, Accountability, SelfRegulation; 4. Building Expertise; and 5. Developing Emotional Intelligence (selfawareness, self-management, motivation and empathy). you and I dear reader) was made suspect even by the fickle Secretary of State for Environment, Food and Rural Affairs.

Professional relationships can become one sided or stressed; there is a risk of falling foul of stepping over the professional line and offerring advice which is what we believe the client wants to hear and not what they need to hear.
This will help create a sensible balance between doing what our client expects and keeping within the standards. This has a bearing on Emotional Intelligence (Item 5) which is considered by many to be essential in respect of career growth, rather than only relying on Items 1 to 4. Humans have an innate drive for acceptance and a need to please others. Professional relationships can become one sided or stressed; there is a risk of falling foul of stepping over the professional line and offerring advice which is what we believe the client wants to hear and not what they need to hear. This points back to diligence, honesty, impartiality and most of all integrity. Professionals MUST be willing, in fact, are honour bound, to deliver bad news
when necessary and say “no” to a client at times when the client would prefer a “yes”. In recognition of such rare stresses, with proper and due acknowledgement of mental health issues, chartered organisations provide support and advice in a caring and supportive manner.
This essay is just a taster to spark discussion and hopefully inspire you to become a better professional. Once you embark on a professional career the journey does not end with chartership; that really marks the start of your professional life. You may consider going beyond chartership and consider becoming a SiLC, to improve your professional standing. Ultimately, you only get out what you are willing to put in. The rewards and enjoyment you receive will be well worth it.

Borehole Sites and Operations Regulations 1995
T
he Borehole Sites and Operations (BSO) Regulations were made under the Health and Safety at Work etc Act 1974 and came into force in 1995. Although many of the requirements in the BSO Regulations are now carried out routinely, they are still legally enforceable. From discussion with various people in the geotechnical industry, and with the HSE, these regulations appear to have largely been either forgotten or overlooked. The purpose of this article is to remind AGS members of the existence of these regulations and to provide a brief summary of what they entail. The regulations can be read as a Statutory Instrument on: https://www.legislation.gov. uk/uksi/1995/2038/contents/made and also, together with HSE guidance in “A guide to the Borehole Sites and Operations Regulations 1995”, 2nd edition published 2008. A webfriendly version of the printed version, adapted for online use, is free to download from http:// www.hse.gov.uk/pubns/books/l72.htm or it can be purchased from HSE Books (£18.00), ISBN 978 0 7176 6287 6. The BSO Regulations are mostly intended to

cover borehole operations for prospecting and extraction of minerals, but they also include boreholes for geotechnical investigation under the category of “Boreholes for any other purpose”. The regulations require notification to the HSE of borehole sites and operations where the boreholes are 30m deep or more, and within a Mining Area. The boreholes may be being drilled in the future, are being drilled, or may have been drilled and have not yet been abandoned.. A Mining Area is defined as land which lies within 1000m, measured in any direction in 3 dimensions, of any mine currently being worked, or disused, or land where a licence to mine minerals has been granted for coal, natural gas, coal bed methane, or other minerals, in natural strata. Mines include shafts for access, ventilation or pumping, underground roadways, adits, and stopes but do not include opencast mines or quarries. Boreholes used for the storage of gas in natural strata reservoirs from which oil or coal bed methane has previously been extracted are also included as mining activities.

Boreholes for extraction of landfill gas, along with offshore installations or activities carried out from such installations, are excluded from the BSO Regulations. However, an installation that is connected to land by a permanent structure is not an offshore installation and would be included.
For drilling of boreholes 30 metres or more in depth, inside a Mining Area, Regulations 6(3) and 6(5) apply. These are as follows: •
Regulation 6(3): “Where a borehole is being drilled within a mining area to a depth of 30 metres or more, the person entitled to drill the borehole, within 30 days after commencement of its drilling, shall notify the Executive the particulars specified in Part III of Schedule 1 [see below].”
•
Regulation 6(5): “The operator of a borehole site or, in the case of particulars previously notified under paragraph (3), the person entitled to drill the borehole shall ensure that the Executive is notified as soon as reasonably practicable of any material change of circumstances which could

The BSO Regulations are in addition to the Health and Safety procedures that are commonly carried out to meet current requirements and expectations applicable to ground investigation works. They are also additional to the requirements to liaise with and inform the Coal Authority when drilling in coal mining areas. There may also be requirements to liaise with other authorities for drilling in mining areas for minerals other than coal.
