CCS was engaged by the building owner to provide a solution to relevel the foundations of both wings of units, the lift, the stairway and the gym building adjacent. By working alongside Geotechnical & Structural Engineers, CCS was able to provide a robust solution for the client which enabled them to continue to have the top two levels of the apartment buildings occupied whilst the work was being completed.
Before Releveling
- This particular building is a three Storey, dual-wing apartment block with 34 units constructed of tilt-slab concrete located in Christchurch’s CBD
- The site soil conditions were gravel, silt and peat with a high water table.
- The rear of each wing had dropped by 316mm and 266mm, respectively.
- For the duration of the lift the tenants continued to occupy the upper two floors
- All services (sewer & storm water) remained connected for the duration of the work
After Releveling
- Work was completed in stages (one wing at a time and finally the lift shaft and stairs. The gym building was completed at the end)
- 113 piles (3m deep) were installed around the building.
- Both apartment block wings and the free standing lift shaft were relevelled
- The maximum lift was 230mm
