Slide 5 - Ground Investigations
Medium Term Solution Phases 2/3
- Groundworks nearing completion in coming weeks
Long Term Solution
- Tender awarded to Structural Soils Ltd
- Groundworks commencing in coming weeks
- 16 week groundwork period (subject to weather)
- Majority of works on slopes above the A83
- Some locations immediately below A83
- This will require traffic management and single lane closures, likely over longer extents than currently experienced at present
