Brownfield Summit 2020

12 May 2020 | London

About this stream

Building on the success of previous ground gas conferences, this is the go-to event for regulators, consultants, remediation contractors and other industry experts concerned with all aspects of ground gas risk assessment, verification, and protection. 

This year's conference will provide a varied mix of new research, policy updates, practical insights and topical case studies on issues including:
 

  • Recent updates to current ground gas guidance and best practice 

  • Innovations in ground gas monitoring and risk assessment, especially on more complex sites

  • Effectively evaluating soil vapour intrusion

  • Recently published findings on the investigation into mine-related CO2 emissions 

  • Optimising the use of continuous monitoring and environmental data

  • The design of robust and compliant protective measures for methane and carbon dioxide ground gases in new buildings and retrofit

  • Strategies for improving the quality of verification and testing

Registration & Refreshments

Understanding the True Risks from Ground Gases and Soil Vapours to Provide
Cost-Effective Solutions to Brownfield Development

  • Clarifying the requirements of current regulations for ground gas and vapour risk assessment
    on development sites and recent progress made both in the UK and internationally

  • 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

 Morning Refreshments & Networking

11:15

Case Study: Demonstrating a Multiple Lines of Evidence Approach for a Complex Ground Gas Risk Assessment

  • Developing and using a robust Conceptual Site Model (CSM) to identify all possible Source-Pathway-Receptor linkages

  • Best practice in collecting continuous gas monitoring data

  • Using multiple lines of evidence and site-specific DQRA to determine accurate and justifiable
    site-specific ground gas risk values

11:40

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.

Q&A

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

 

Tom Henman, Director - Geosciences, RSK

SESSION 1: GROUND GAS RISK ASSESSMENT

SESSION 2: GAS PROTECTION DESIGN & INSTALLATION

12:15

Retrofitting Gas Protection Measures to Existing Buildings: Outlining the Findings, Conclusions & Recommendations of Soon to be Published CIRIA Guidance

  • Background and approach to retrofitting (existing buildings, refurbishments and extensions)

  • Risk assessment for potential retrofitting projects (permanent gases, radon, VOCs
    and trace gasses)

  • Including risk perception and communication issues

  • Options appraisal, available measures and verification

  • Conclusions and recommendations from the project

Nina Sopp, Geoenvironmental Engineer, BuroHappold Engineering

Lunch and Networking

13:45

Interactive Break-Out Session

This focused, interactive session runs cross-stream giving delegates the opportunity to discuss a key topic of interest to them in a more participative format with professionals working across different areas of brownfield risk assessment. Each session will be led by a facilitator who will lead the discussion and encourage maximum debate and sharing of ideas.

Afternoon Refreshments & Networking

SESSION 3: VERIFICATION OF GAS MEMBRANE INSTALLATION

It is widely felt that there is a lack of confidence in the procedures for assessing and verifying the correct installation of  gas protection measures within new developments, and so a number of options are being considered within the sector to address this. This session will look at a couple of proposed measures, followed by an audience discussion on the likely effectiveness of these measures and further action that could be taken. 

15:20

Outlining the Objectives and Timescale of the Proposed Gas Protection Verification Accreditation Scheme

  • Detailing the key objectives of the scheme and results of the recent consultation

  • Outlining the accreditation and scrutineering process

  • To what extent might the scheme become compulsory?

Nicola Harries, Project Director, CL:AIRE

15:30

Outlining the Role of the British Verification Council in Improving Gas Protection Verification Standards

  • Exploring key issues that often arise in installation of gas protection measures and how to avoid them

  • Outlining the aims and principles of the BVC and how it hopes to raise standards within the industry
