You can’t always establish the in-ground conditions with absolute certainty.  But you need to have confidence in the design and construction of foundations for buildings, especially high-rise structures.  

At Coffey we develop robust and cost-effective solutions that work, even when there is an element of uncertainty. 

From single storey domestic houses to the tallest buildings in the world – we design foundations for all types of structures.

We provide a full range of cost-effective design and construction services for building foundations with special expertise in high-rise structures. Our designs will satisfy engineering, environmental and building code requirements. This includes ground investigation and interpretation, foundation design and construction supervision.

Our team has a detailed knowledge of geology and how it influences the ground conditions and engineering properties of subsurface soils. We use this to understand the geological history of the site and characterise the key engineering properties of the subsurface soils. Then we undertake a series of design analyses using numerical and analytical software packages.

We work closely with structural engineers so that the foundations are compatible with the structure and all relevant foundation loadings are accounted for.

Our design approach

We have developed a systematic three-level approach to foundation design, involving preliminary assessment of foundation requirements, detailed design and optimisation of the foundation system.

Our design process considers all forms of loadings that could arise from ground movement actions during construction, including the possible damaging effects on the strength of the foundations of repeated or cyclic loadings due to wind and earthquakes.

We use a combination of our own specialist in-house software and state-of-the-art commercial software to analyse and design piled and piled-raft foundation systems.

Economical foundation design

Based on our knowledge of local codes in different parts of the world, we can achieve up to a 30% reduction in the number of piles needed compared to conventional designs – providing significant cost and time savings.
