Engineerisk is a consulting company
specializing in snow-avalanche protection engineering

engineerisk expert tout terrain

The skills of the associates Philippe Berthet-Rambaud (Docteur Ingénieur en Génie Civil) et Fanny Bourjaillat (Doctor Engineer in Civil Engineering) and Fanny Bourjaillat (Engineer Natural Risks and Artificial Snow) allow Engineerisk to carry out all the studies regarding snow and avalanche risks:

From the phenomena analysis:
- Hazard characterization: statistics of climate and weather data, analysis of the topography (DTM), visits and surveys on site ...
- Zoning, risk mapping ...
- Post-accident response
- Related phenomena: snow gliding, snowdrift…
To the definition of the most appropriate protection solutions:
- Proposal and dimensioning of active (supporting structures, wooden sleeves, preventive artificial release, wind structures ...) or passive (dam, splitter, galleries ...) protections
- Artificial release network and procedure through avalanche control plan
- Architectural recommendations, definition of pressure for buildings and other infrastructures subjected to avalanche impacts
To achieve this, Engineerisk uses a combined approach based on:
- the usual expertise approaches
- the international state of the art in snow-avalanche engineering through continuous monitoring and regular participation in conferences
- network of European and North American consultants network
- In-depth knowledge of the various techniques and solutions proposed by manufacturers
- Methods and software developed by the SLF Institute of Davos, world reference on these topics, in order to also propose fine numerical modeling of the phenomena:
• Dense flow: RAMMS
• Powder cloud: AVAL1D

By remaining strictly focused on snow and avalanche risks only, Engineerisk is positioned as the specialist of these issues, in France and internationally.
