[Medin_standards] review of draft MEDIN guideline for geotechnical site investigations

Wed Mar 30 09:18:26 BST 2016

HI Sean,

Sorry, I was only able to give this a quick look. There is not a huge amount of this that is familiar to what we do at SAMS ( though we have done PSA in the past), so our experience is limited, as is my own knowledge of this type of sampling. So not entirely sure how useful my comments may be.

Some quick comments though:

There is reference to ISO 14688 in a few tables ( and BS1377 Part 2), so it might have been useful to have  copy of these included with these documents - unfortunately you have to buy it, from the ISO website if you want to view it. It may be that the few queries I have are actually covered under 14688 or BS1377.

I presume colour has to be mentioned somewhere ? - would this be included under Specimen - descSpecimen as part of 14688 ?

Is there actually room here, say in PSD,  for a textual classification of the specimen type  such as under Wentworth or  even Shepard's  or Folk's classification scheme: or would that be considered too 'interpretive' at this stage ? Or, again,  is that covered under the standard (BS1377 Part 2) ?

What about geochemical analysis of samples - is that normally done in a geotechnical context (and even not, are subsamples sometimes passed on to others for this sdort of analysi ) - or is this  something covered more under the Sediment sampling guidelines ?

Steve

Dear MEDIN Standards Working Group,

Please find attached the first full draft submission of the guideline for geotechnical site investigation, from Cathie Associates. There are some notes from their project manager below, explaining some of the choices they have made.

Could I please ask that you review the documentation and get any feedback to me before 30 March, so that I can compile everything for return to Cathie Associates on 30 March.

Areas that are of particular interest would be

(i)                  how well the draft guideline meets the original specification (which I have attached as geotechnica_data_specification_v1.doc).

(ii)                Usability of the guideline

(iii)               Clarity of examples and descriptions

(iv)               Technical accuracy

I appreciate that, as you all come from a variety of backgrounds, you may not all be able to provide feedback on all the above points, but MEDIN will welcome any contribution you can make to the review.

I look forward to receiving your comments and would like to wish you all a happy Easter as well.

Regards,

Sean Gaffney

Dear Sean

Please find attached our first draft submission of a MEDIN guideline for geotechnical site investigation, with accompanying workbook. A few notes below:

Cover Page

I have noted ourselves as authors, however there is a great deal of generic text relating to MEDIN, which appears standard across the guidelines. I am not sure how this should be best acknowledged, I will leave to MEDIN.

Cover Page

Assumed some fields relate to MEDIN activities, highlighted in red: Reviewed by, Date Reviewed, Date approved and published, Date last checked for accuracy

Cover Page

Keywords: As our contents are so extensive, the individual keywords would be rather a big chunk of text. I have put the overarching 'Geotechnics' keyword from the list as an umbrella term for brevity, but please flag if the larger list would be preferred.

Guidance (pg 13 and under Heading)

I have included a full guidance section as found in some other guidelines, as I personally have found it useful and it provides some additional background information. But then, I also liked how some of its content was put in relevant places through the offshore litter guideline... so I have not amended the guidance section, and will wait for the review period and preferences from yourselves on whether to keep a uniform section or migrate the text to where it best fits.
