The project involved the remediation of four former gasworks site under a single contract and provided savings of over 30% when compared to implementing separate contracts at each site. The UK’s first multiple site ‘hub and cluster’ approach was implemented under the Contaminated Land : Applications in Real Environments (CL:AIRE) Code of Practice, which enabled movement of all material to be audited and to meet the requirements of multiple regulators.
After several phases of assessment, four sites were selected to form the ‘cluster’, with Partington as both the hub site where the Soil Treatment Centre was established and a remediation site with the associated ‘cluster’ sites at Prescot, Runcorn and Warrington. Each of the sites had an incumbent engineering consultant managing the remediation strategy and design for the site.
We worked proactively with the overall Project Manager, Worley Parsons, to value engineer the works whilst remaining true to the original designs which were warrantied. We developed a Materials Management Plan to track material movement and treatment with over 49,500m³ being excavated and 30,000m³ was re-used which represented 70% of the treatable material.
This challenging project was delivered within the agreed budget and programme.
