All projects have their own key risks.
What are the Top 10 most significant and commonly occurring ground contamination risks to project cost and programme?
- Asbestos in Soil
- Satisfying Planning Requirements
- Soil Management
- Groundwater
- Soil Disposal
- Effective Remediation
- Ground Gas
- New and Emerging Contaminants
- Joined up Site Solutions
- Legal compliance
All GRR projects have their own key risks.
Asbestos in Soil can be one of those risks. Explain how.
> Asbestos fibres can be spread widely in Made Ground.
> The unexpected presence of asbestos increases project cost and programme and it is a legal requirement to manage it.
> Effective investigation and advice around asbestos in soil is essential.
All GRR projects have their own key risks.
Satisfying Planning Requirements can be one of those risks. Explain how.
> UK planning is changing. Ground conditions require time to investigate.
> Good advice is essential to input to project design, satisfying conditions and if needed, supporting inquiries.
> Appointing trusted advisors will mitigate against project duplication and potential delays.
All GRR projects have their own key risks.
Soil Management can be one of those risks. Explain how.
> Is a soil a waste or not? Not always a clear cut question?
> With the cost of soil disposal being high, consideration of reusing soils in development following strict protocols must be a Number 1 priority.
All GRR projects have their own key risks.
Groundwater can be one of those risks. Explain how.
> Groundwater is everywhere, it’s a receptor and a pathway and can impact construction and drainage solutions.
> Project starts can be delayed where seasonal monitoring is required
> Arduous legal agreements may result if the project itself impacts groundwater quality.
All GRR projects have their own key risks.
Soil Disposal can be one of those risks. Explain how.
> Soil disposal comes at a high cost.
> To avoid unpleasant surprises, be sure to have robust soil waste classification to comply with legislation.
> And plan your waste classification programme to match your intended works.
All GRR projects have their own key risks.
Effective Remediation can be one of those risks. Explain how.
> Remediation is a significant commitment in time and money.
> A well planned and designed remediation scheme should have the flexibility to deal with the uncertainties of managing contamination (giving confidence to stakeholders).
> Better design equals better costs and outcomes.
All GRR projects have their own key risks.
Ground Gas can be one of those risks. Explain how.
> Ground gas can be underestimated as a development risk.
> It must form part of the site investigation design.
> Mitigation needs to be incorporated into construction designs at the outset as retrospective mitigation is costly and may not always be possible.
All GRR projects have their own key risks.
New and Emerging Contaminants can be one of those risks. Explain how.
> Tomorrow’s contamination may be happening today
> And there are some new contaminants that are particularly difficult to deal with
> Including fire-fighting foams and residues which have been proven to be highly damaging to the environment.
All GRR projects have their own key risks.
Joined up Site Solutions can be one of those risks. Explain how.
> Ground contamination affects projects in unexpected ways.
> Flooding and Sustainable Urban Drainage Systems may mobilise contamination from otherwise dry soils.
> This may represent a risk of future pollution and potential liability for the developer or site owner.
All GRR projects have their own key risks.
Legal Requirements can be one of those risks. Explain how.
> European legislation forms the backbone of our environmental protection regime.
> This could change and we will see a continued push to remove red tape and reducing input from Government and regulators,
> Which is a big change for contaminated land.
