  • Understanding where uncertainties and misconceptions occur in risk-assessing the most common contaminants and how these can be addressed:

    • techniques for preventing overly conservative or incorrect assessments

  • Effectively interpreting continuous gas monitoring data and analytics

  • Understanding the reasons for elevated gas concentrations to determine if / the extent to which gas membranes are required

Steve Wilson, Technical Director, The Environmental Protection Group Ltd (EPG) 

10:25 Examining the Risk of Carbon Dioxide Arising from Disused Mineral Mines and the Implications: Recent Findings

RSK was appointed by the Scottish Government to carry out a research project into the prevalence of CO2 from disused mineral mines and the resulting risk to residential buildings, which was published recently. This talk will cover:  

 

  • Introduction and context to the Scottish Government research project

  • The Gorebridge incident in Scotland and other identified incidents of mine related CO2 emissions in the UK and beyond

  • The nature of abandoned mine-workings and circumstances where risks related to CO2 emissions are raised

  • Key findings of the research report including expert views on the adequacy of current standards and guidance versus use of mandatory gas protection measures in coalfield areas

  • The role of uncertainties including groundwater rise, climate change effects and cumulative development

  • Report recommendations including proposed changes to planning and building standards and guidance,  further research requirement and wider implications for all UK coalfields beyond Scotland

10:50 Q&A followed by ad break, sponsored by Groundsure

11:10 Case Study: Innovative and site-specific ground gas investigation and assessment at Whitecliffe, Kent

This case study will explain how the latest ground gas investigation and risk assessment methods have added significant value on a major development project. The site is a 260-hectare former chalk quarry with consent for residential development with over 6,000 homes. Land forming earthworks are in progress, with the reuse of millions of cubic metres of soil. The challenging ground conditions have led to unique ground gas considerations. While the initial cost of investigation and assessment increased to accommodate the innovative approach, the long-term benefits will dwarf the initial investment. 

 

The presentation will explore:

  • The importance of the conceptual model in defining the gas risk assessment

  • How continuous monitoring techniques and advanced data analytics can be used

  • The benefit of multiple lines of evidence in robustly demonstrating conclusions and supporting regulatory approval to novel approaches that go beyond published guidance

  • The potential tension between good science and commercial risk

Amy Juden, Contaminated Land Consultant, Arup 

11.35 Examining the Role of Sewers as a Preferential Pathway in Vapor Intrusion Risk Assessment ​

The role of sewer systems as preferential pathways for vapour intrusion is poorly understood. As a result, these pathways are often not considered when developing vapour intrusion risk assessment or mitigation strategies. This presentation will explore the importance of sewers as preferential pathways in buildings and how they should be accounted for when developing the CSM.

10.50 Achieving a Better Understanding of What is Underground: Presenting Two Collaborative Projects

 

The Outcome of the National Underground Asset Register Pilots

Did you know... that there are 1.5 million kilometres of underground services in the UK all working hard to keep our country supplied with water, gas and electricity.  With all these assets and different companies involved working beneath the ground is both complex and inefficient. The estimated economic cost of accidental strikes on underground pipes and cables is £1.2 billion a year. Workers who strike gas pipes and electric cables by mistake can also put themselves and others in danger of death or serious injury.  These are just two of the reasons why the Geospatial Commission launched our National Underground Assets Register Pilots, to make it easier to find out what exactly is beneath the ground.

 

Holger Kessler, Geoscience Technical Advisor, Geospatial Commission

 

The Dig-To-Share Initiative: “Unlocking”, and Increasing the Availability of,
Sub-Surface Data  

The Dig-To-Share project started life as a 1 year project aimed at unlocking the vast quantities of borehole data locked away inside a system that has no clear central repository or submission routes. By utilising the BGS’ national archives as that repository, and encouraging people to share their data in a more collaborative way, the Dig-To-Share Team hope to overcome the difficulties associated with sharing data (embedded in contract liabilities, ownership of data) and help steer the conversation in a more open way. The project aimed to unlock 10,000 borehole in its start-up year. Listen in to find out what we have achieved so far, and how the project has progressed in the 2nd year of life. The talk will also touch on how to access the data through software and portals and what data is stored. And no doubt we’ll also touch on the thorny issue of confidentiality…

11.30 Q&A

SESSION SEVEN, 26 MAY AFTERNOON

Maximising the Potential of Your Site & Project Data 

14.30 Streamlining Assessment of Environmental & Geo-Technical Risks to Improve Land Use & Development Decisions

As geoenvironmental and geotechnical characteristics at sites are so variable the Consultant’s role is to help their client to balance certainty and the cost of acquiring information reach a suitable level of certainty. With the explosion in technology, new national data sets being created and ways of using them are being applied to help get ahead of the uncertainty and allow good decisions to be made early in a development of purchase.

Ceri will take a look at open data, some of the new data in development and some of the ways familiar data is being used to help the decision-making process.

 

Ceri Sansom, Head of Consultancy, Groundsure

 

14.55 Using the New CIRIA Asbestos App to Improve the Identification &  Management of Asbestos on Site


This presentation will outline the potential uses of an app that has been developed in conjunction with industry to provide a smart-phone based tool that aids in the challenges of spotting suspected asbestos in soils and provides first-response guidance on what to do as a result. Feedback from early adopters of this App provides insight as to how the App is working in practice.

15.35 Techniques for Improving & Verifying the Quality of Data Collection

 

The benefits of technology and new digital techniques in facilitating data collection are being increasingly recognised. However, it does not matter how advanced your technology is if there is a fundamental problem with data quality. Inputting inaccurate data into your modelling will have a significant impact on risk assessment and future decision making. Trying to incorporate historical, desk-based information into new software programmes can be difficult and possible errors and limitations in the data can be overlooked. This presentation will look at these challenges recent industry examples to summarise the challenges presented and suggest solutions for best managing them to ensure accurate and reliable data collection and input.
