Tailored Solutions for Your Projects Needs
Specific foundation design tailored to site ground conditions.
Foundation design is a critical aspect of any construction project. KGA provides bespoke solutions tailored to your site’s specific geotechnical conditions, ensuring stability and long-term performance. Following thorough subsurface investigations, KGA determine the optimal foundation solution to meet project performance, environmental and economical requirements.
From conventional shallow foundations for residential structures to advanced foundation systems for challenging soils, KGA ensures every project starts with a solid foundation.
Soil-structure Interaction and Site Integration
The foundation selection process must account for the effects on nearby structures and infrastructure. KGA conducts detailed assessments to ensure foundations do not negatively impact neighbouring properties. By addressing these considerations early, potential risks are mitigated, safeguarding both your project and its surroundings
In these cases, detailed iterative soil-structure interaction analysis involving both geotechnical and structural engineers is required to assess the real world behaviour of the system. KGA regularly undertakes soil-structure interaction assessments with our Structural Engineering partners
Foundation Design Services
KGA’s team of engineers have extensive experience in analysis and design of a wide variety of foundation solutions:
- Including strip, pad and raft foundations
- KGA routinely undertake detailed settlement analysis for shallow foundation design, determine soil springs for structural analysis of rafts and slabs and provide design recommendations for foundation design
- KGA’s engineers are industry leaders in deep foundation design including bored, driven and CFA piles as well as Screw Pile design
- KGA specialises in vertical and lateral pile analysis including generating PY curves for structural pile design
- Liquefaction effects on deep pile foundations including assessment of negative skin friction and neutral axis analysis
- Ground improvement techniques in combination with shallow foundations have become common place following the Christchurch Earthquakes in dealing with soft, deep and potentially liquefiable soils. Ground improvement techniques are constantly evolving and KGA is at the forefront of innovative design solutions including Stone Columns, Rammed Aggregate Piers, Olivier Piles / displacement piles, stiffened gravel rafts, deep soil mixing, and injection methods
- Design and analysis of foundation systems to resist uplift or tension loads, including hold down anchors and cone pull out calculations.
