Constrained deeper excavated foundation options.
Groundwater ~2 m below ground
01
The uncertainty
The project team needed to know whether conventional shallow foundations were suitable for the proposed self-storage building before detailed design.
02
What we established
Shallow foundations were unsuitable. Groundwater constrained deeper excavated options, making piling the more appropriate approach. Ground improvement remained a potential alternative.
03
What changed
The findings gave the design team a clear basis for progressing the foundation strategy, alongside site-specific information for pavement design.
04
How we got there
- Geotechnical investigation using window sampling and deeper boreholes to establish ground conditions
- In-situ and laboratory testing to inform foundation recommendations
- Groundwater assessment to identify construction constraints
- DCP testing to inform pavement design
