Geotechnical engineering and geoenvironmental specialists deal with risk daily from commencement of a project through to final delivery. Working with the ground brings with it inherent risks and it can be a fine line between managing or taking risk. Our understanding of the ground is continually evolving and keeping up to date is important.
This full day, CPD conference organised by the Association of Geotechnical and Geoenvironmental Specialists and brought to you by the Geotechnical and Contaminated Land Working Groups, will explore the management of risk across a variety of subjects, including updates to piling through layered ground guidance, underpinning and Cone Penetration Testing. We will also explore topics often not considered such as cognitive bias and learn about changes in environmental legislation and policy.
Ground Risk Conference: Are you Managing Risks or Taking Risks? is aimed at attendees at any stage of their career, who are involved in development projects from concept and planning, through to implementation. Attendees will be provided with opportunities for networking and will have the chance to question our expert speakers.
Speakers for the event include Stephen Tromans (39 Essex Chambers), who is recognised as one of the leading practitioners in environmental law in the UK, Matthew Penfold (GEA), from the Underpinning Focus Group, Alex Lee (HKA), Chair of the National Brownfield Forum and AGS Chair Elect and Steve Wilson (EPG).
Registration for this event is closed.
Foundation Risks & Problems; A Structural Engineer’s Perspective
Patrick Hayes, Technical Director at Institution of Structural Engineers
Patrick will draw on his own experience, member feedback and CROSS reports to highlight the most frequent and serious building foundation design issues, look at underlying causes and how structural and geotechnical engineers can work together to resolve them. The range of topics will cover shallow foundations, deep foundations and basements.
Piling Risk Assessment for Contaminated Sites
Steve Wilson, Technical Director at The Environmental Protection Group and Amy Juden, Associate at The Environmental Protection Group
The presentation will discuss the update of the Environment Agency guidance on piling in contaminated ground that is currently in progress. It will discuss some of the key contents of the new guidance.
Bias in the Delivery of Geo-Environmental Assessments
Alex Lee, AGS Chair Elect and Principal at HKA
In performing geotechnical and environmental assessments for example when we develop and deliver our models and designs then bias can and does on occasion arise. Such can bring both reputational damage and risks of litigation. Decision researchers1 have identified many biases in human judgment and decision-making. Most behavioral research addresses cognitive biases— faulty mental processes that lead judgments and decisions to violate commonly accepted normative principles. Equally important, but much less studied, are motivational biases, which include conscious or subconscious distortions of judgments and decisions because of self-interest, social pressures, or organizational context. In this presentation, the speaker will discuss several of the more common types of bias while making specific reference to examples from Geo-environmental investigations and assessments. He will also introduce how we may self-check and move towards debiasing our reports.

New Challenges: New Risks
Stephen Tromans KC at 39 Essex Chambers
Stephen will take a look at the new challenges, opportunities, but most of all risks, facing practitioners.
Groundworks Litigation & Contracts
Jon Palmer, Technical Director at HKA Global
The presentation will introduce to the scope and global distribution of engineering disputes drawn from the HKA database, with particular reference to the area of unforeseeable ground conditions, including:
- The definition of “unforeseeable” and importance of site investigations.
- The role of designers and contractors and difficulties determining liabilities.
- How “unforeseeable” is addressed in conditions of contract.
The presentation comments on the common issues of geotechnical disputes, centring on areas where general principles are often overlooked. Also, an introduction to dispute resolution methods, and the role of the expert witness in these proceedings, concluding with illustrative case studies.
Basement underpinning: Are we ‘managing’ the risks?
Matthew Penfold, Principal Geotechnical Engineer at Geotechnical & Environmental Associates, Katharine Barker, Associate Geotechnical Engineer at CampbellReith, and Arash Azizi, Lecturer at University of Portsmouth
Underpinning is widely adopted in domestic basement construction with little or no (reported) impacts. However, current planning procedures often include a requirement for detailed assessment of the likely ground movements and predictions of damage. This has highlighted the lack of consensus on the likely range of movements around underpinned basements, as well as exposing the general lack of guidance and supporting literature available to practitioners and auditors alike.
To better understand these issues, a focus group was set up by members of the Geotechnical Working Group with the University of Portsmouth with the aim to take the first steps to better understand and provide predictive tools for ground movements associated with underpinned basements.
How Misunderstood CPT Data, Processes and Specifications Can Lead to Ground Risk
William Bond, CPT & Geotechnical Account Manager at Royal Eijkelkamp
Cone Penetration Testing (CPT) is a soil investigation technique that was developed some 90 years ago and is now utilised all around the world to establish soil behaviour and stratigraphy. The technique’s rapid nature, instantaneous data, multiple geotechnical measurements and high level of sensitivity make it a powerful tool for building detailed ground models. When correctly performed, processed and analysed CPT is an ideal tool to minimise ground risk. However, as a technologically advanced method, a lack of understanding can lead to erroneous and misleading data which, if unfamiliar, can be hard to identify.
