Client: UNIPAK S.A.L. – TISSUE MILL
The “Tissue Mill” factory in Sanita’s compound Halat. The project consists of creating a space (60x15m2) under an existing structure in order to accommodate a new manufacturing machine. The soil consists of Gravelly Clay material at the top 5m, then the hard marl. The excavation needed for the new structure was about 6m deep. The challenge in this project was to complete the drilling, micropiles / anchors installation, concreting, excavation & tensioning in a tight & delicate environment, and within a very tight schedule, while the factory next door remains operational. The Design/Build solution consists of installing Micropiles with Active Anchors as a shoring system to support the existing structure and infrastructure and retain the excavated sides. The Micropiles were 10cm in diameter with 1.2m spacing c/c, one row of active anchors spaced 3m to 4m & tensioned against a final concrete wall.
