Reclamation application

Spotlight - Geotechnics

Scott Wilson is providing geotechnical design and supervision services in connection with the reclamation and redevelopment of the former Brymbo Steelworks near Wrexham. Around 200 years of iron and steel production generated 3M. m 3of surplus material at the site, containing a range of geotechnical hazards that includes abandoned mine shafts and potentially expansive slag.

The reclamation scheme involves bulk excavation to generate clean fill, extracting associated minerals - mainly coal - controlling the compaction operations, and treating old mineworkings. Once the site has been restored, it will be used for housing and industrial development.

Scott Wilson is supervising the placement and compaction of approximately 1M. m 3of coal measures materials to form the development platforms. Large amounts of geotechnical data are generated by the monitoring regime, which includes daily in situ testing by nuclear density gauge, and on and off site laboratory testing of compaction and classification properties.

The consultant has worked with Leeke Associates, the UK distributor of gINT software, to develop a data management system using gINT Professional Version 6. The system incorporates a data entry Excel spreadsheet, which is imported into the gINT database, which then stores information such as the test locations, results and specifications and query results for periodic averages for each specification material type.

The software generates a range of reports such as maps, tables and graph reports for analysis, and periodic reporting for the client.
