Risk management procedure in the construction of deep foundations

Due to the world population growth and the need of contemporary way of life, an increasing number of edifications are being constructed in places less adequate to do so from the geotechnical point of view. This, allied to poor geotechnical studies, have driven for several modifications
on projects at the construction phase. To solve this, over the past 40 years, the need for deep foundations, especially piles, has increased, and so the inherent construction costs. The application and applicability of several constructive technics are often disregarded or not implemented in an adequate way, bringing large
financial consequences to the project stakeholders. All the above problems may be quantified in monetary terms and managed on the basis of acceptable risk. Thus, a simple and semi-quantitative methodology and best practices are required to mitigate these situations while keeping a sustainable cost control.
