Risk management practice for geotechnical engineers, Balangero Asbestos Mine Dumps Geo-Environmental Restoration.
Guest lecture at University of Alberta Geotechnical Center: online.
A complex problem encompassing
- slope stability,
- erosion, and finally
- dust control,
as a matter of fact one of the top environmental restoration hazardous spots in Italy at the time.
Formulation of the success criteria involved finding a compromise among various parameters under significant uncertainties. As a matter of fact geotechnical data were scarce and in some cases impossible to obtain due to hazardous conditions (stability and health and safety).
Quantitative risk analysis guided all the design team choices, thus leading to a sustainable, balanced design that has since survived a number of extreme events such as Medicanes (Mediterranean hurricanes, thanks to climate change). The presence of:
- population at close proximity,
- public pressure via media outlets, and finally
- a set of stringent environmental constraints
guided the team to select innovative solutions. As a result, classic haulage trucks were replaced by a rope transportation device. In addition to reducing dusting problems the rope transportation significantly reduced the project’s carbon footprint.

Balangero (Italy) Asbestos Mine Dumps Geo-Environmental Restoration
The project was the result of an international design competition and was a world-first. Indeed it represents a first ever example of a design competitive bid won using risk-informed decision-making.
