VertaseFLI Win at 2013 BB Awards

VertaseFLI are pleased to announce that, along with our partners, Contain, Arup and Neath Port Talbot Council, we have won a Brownfield Briefing Award for the Best Conceptual Design for the remediation works undertaken as part of the construction of the Port Talbot Peripheral Distribution Road (PT PDR) and the project was also highly commended in the Best Reuse of Material category.  The Brownfield Briefing Awards celebrate excellence in the brownfield sector and recognise outstanding achievements made through the use of innovative techniques, awareness of sustainability, engagement of stakeholders and demonstration of best practice. 

VertaseFLI were appointed by Costain on behalf of Neath Port Talbot Council to undertake remediation works along the route of the PT PDR where it passed through an area of the Port Talbot Steel Works site which has an extensive historical legacy.  The site had a heavily industrialised history, beginning at the start of the 19th Century with the development and operation of the Margam Copper Works and later evolving into the present day steelworks plant.

Costain’s consultant, ARUP, undertook site investigation and risk assessment works as part of the PT PDR scheme which identified the requirement for the remediation of approximately 6,000 m3 of soils that were impacted by significant organic contamination, including total petroleum hydrocarbons and poly aromatic hydrocarbons, in particular naphthalene .

VertaseFLI successfully designed and executed a remediation scheme that involved treatment via stabilisation and solidification.  The remediation works successfully treated grossly contaminated material and reduced naphthalene leachate contaminants to below the materials reuse criterion.  The stabilised material was geotechnically competent for reuse under the PT PDR road embankment, resulting in no requirements for off-site disposal. The remediation works were also designed to maximise and enhance the sustainability of the works though the careful selection of appropriate stabilisation reagents, whilst a programme of comprehensive environmental monitoring demonstrated that the treatment of the noxious contaminants did not have any impact on the surrounding environs.

This remediation technique demonstrated a sustainable and cost-effective remediation solution that can be designed, adapted and delivered to all sites, even those containing gross levels of contamination.  All contaminated soils encountered on site were treated and retained on site with no material requiring off-site disposal.
