Quality assurance in former open-cast mines: measurements inform site decisions
Soil compaction during the restoration of former open-cast mines requires traceable quality checks. SGL Spezialleistungen needs more than measurements stored on machines: execution, performance and deviations must be visible the same day for timely quality assurance and reporting.
The application combines machine data with planning values, compares targets with actual results and makes them available both on site and in the office.
The starting point: machine measurements analysed by hand
The construction machines already recorded measurements on their computers. The bottleneck was the subsequent checking and preparation: repetitive steps took time and required knowledge held by only a few people. A current assessment of the site depended on when this analysis was completed.
The turning point: a daily review process built on raw data
Examined the process with specialists
Interviews showed that the data already existed on the machines. The team lost time in recurring checks, so we modelled the analysis as a continuous digital process.
Imported machine data automatically
Daily offline data feed directly into the business checks.
Compared planning and execution
The planned-versus-actual comparison makes deviations visible and relates them to the quality and performance metrics used by the team.
Provided results at both workplaces
The application works offline on site. When connected, it synchronises with the company server so office analysis and reports use the same data.
SGL Spezialleistungen is a General Atomics Group subsidiary specialising in civil engineering. Its work includes environmental construction, soil compaction and ground stabilisation.
The company mainly operates in southern Brandenburg and on the restoration of former open-cast mines in Lusatia.
