Development and Innovation: A review of 2012

Our ability to provide ‘Ground InvestigTrial Pittingations of Quality and Value’ is confirmed, and to date we’ve completed more than 70 projects with contract values ranging from £450 to £45k, with many for returning clients and a high proportion negotiated. Feedback from regulators, including SEPA and local councils has been positive and encouraging.

There has been development aplenty at Insight GEO over the last year with new sample and equipment store; increased office space; and new computer software, making downloading and sending documents easy via the upgraded fibre optic broadband. We’re also in at the start with the new Keynetix Holebase SI software. Having upgraded to the professional packagTruck on sitee, this will not only produce great exploratory hole records and AGS data, but the interactive mapping element will allow cross sections to be generated with a click (or two) for standard inclusion in our reports. Still at a trial and review stage, this software should transform the way we can interrogate and ultimately present field data – exciting stuff. The increased office capability has been ably supported by admin, accounts and IT input from Claire, Arlene and Gerard – many thanks.

The important commitment to Health and Safety has not been neglected: our NEBOSH qualified advisor, Stuart Beattie has developed the Insight GEO Health and Safety Management System, now in preliminary use and being tweaked to perfection. A new Professionally Qualified Person CSCS card and HSE certified First Aid at Work training for Judith emphasises this commitment.

On site therJudith on sitee have been upgrades too: the new company 4 x 4 vehicle, a capable beast, ‘just in case’ we end up somewhere muddy and slightly inaccessible. Providing project continuity, Judith is on site for the majority of fieldwork. For larger projects and days where being in two places at once would be handy, the experienced support of Gordon or Chrissie on site has proved to be invaluable.

And so to the future – although largely more of the same, and with increased capability we look forward to working with a wider range of clients who are hoping to find an approachable and professional specialist to implement and manage their ground investigations with competence, or add pragmatic geotechnical and geoenvironmental expertise to their projects.

Finally – let the blogging recommence. After many months of ploughing all spare energy into developing Insight GEO behind the scenes, it’s time to start broadcasting achievements and selecting the most useful and interesting industry updates to share. Watch this space in the coming months.

Hot off the Press – Publication of new BS10175:2011

What is BS 10175?

BS 10175 is the code of practice for Investigation of Potentially Contaminated Sites. It gives guidance on the investigation of potentially contaminated land. It also applies to land with naturally enhanced concentrations of potentially harmful materials to determine or manage any risks.

What's the risk?

In brief BS 10175 covers:

a) Setting the objectives of an investigation
b) Setting a strategy for the investigation
c) Designing the different phases of the investigation
d) Sampling and on-site testing
e) Laboratory analysis
f) Reporting, in order to obtain scientifically robust data on soil, groundwater, surface water and ground gas contamination.

Industry Views

Since publication of the initial BS10175 in 2001, investigation strategies and understanding of the risk based approach to sites and site investigations have evolved significantly.  As part of the code update and revision process, a UK wide series of events were held in summer 2010.

Industry Views

Insight GEO attended the event in Perth, where the proposed draft was reviewed and feedback invited. Many revisions received a broad consensus of opinion across the industry representatives which included; regulators, environmental consultants, councils and ground investigation specialists. However, a few aspects such as investigation phasing, prescriptive sampling density and even the definition of potentially contaminated land, inspired lively debate; leaving the drafting committee with a wide variety of views to consider before publication.

Now that BS10175:2011 has been published and BS10175:2001 withdrawn, what difference will it make? - watch this space….

Through the eye of… overcoming difficult access in Stirling

Site entrance door

Insight GEO was approached to undertake a Phase 1 Desk Study and consider preliminary foundation design for a proposed six storey mixed residential and commercial development in Stirling.

The site was wholly occupied by an existing retail building on a busy road opposite the city’s main railway station. Although a main further phase of investigation will be carried out following demolition, the Client was keen to consider the foundation options available at an early project stage.

All things considered, piling into dolerite bedrock was the most likely solution, so rotary coring to determine rockhead depth and rock mass characteristics was necessary. With no direct plant access to the maximum headroom area of just 3 metres and disruption to the existing business to be minimised, there were a few constraints to consider! Fortunately we had used the tiny Beretta T25 drilling rig from preferred subcontractor, JB Site Investigations, in tight spots before. Its driller, Des Hood, is particularly adept at the careful manoeuvring, which would be required. We measured the clearances, and yes, it could just be done – with a bit of internal doorway widening and ramps for steps.

Easy does it...

Safely round a corner

Prior to mobilisation a team from Insight GEO widened two internal doorways and lined the floors and doors around the drillhole with floor to ceiling plastic sheeting to prevent spread of dust and mess throughout the shop. With so much preparation, all went to plan and the shop only needed to shut for one day.

Strong dolerite was proved below 5 metres depth and with all hands on deck to clean up, the shop window display was back in place shortly after completion of the successful investigation. Business as usual!

Insight GEO website goes live – A personal welcome from Judith

Our window to the world is now open and with it, this, our first blog.

Many thanks go to Miles, Sarah and Phil at Creative Canteen, creative design agency extraordinaire. They have translated my scribbles and thoughts for the ’look and feel’ of Insight GEO into a functioning identity that we can be proud of for many years to come. The last project Sarah and I worked on together must have been A Level Geography fieldtrip – so a real treat.

Is there a story behind the logo?

Insight GEO logo

Of course – from my first day on site as a graduate. I asked the driller if I could look down the borehole; he raised one eyebrow and stood aside. Peering into 40m of blackness I realised this didn’t tell me much; without any insight, just a hole in the ground. I worked on that site for seven months and was frequently asked if I wanted to look down any more boreholes! Experience and knowledge has brought insight, which now takes central place. With three strings of casing, our logo looks down a borehole of some depth and complexity, a bit like the original one it was inspired by.
