Alp'Géorisques

What Alp'Géorisques does

Alp'Géorisques is a French private engineering consultancy (SARL) headquartered in Domène, in the Grenoble suburbs, specializing in natural, mining, and technological risk assessment for French public-sector clients. Founded in 1985 by Didier Mazet-Brachet and incorporated in 1991, the firm employs approximately 12 engineers and study managers across hydrology, hydraulics, applied geology, avalanche science, urban planning regulation, crisis management, and GIS. Since 2023, it has operated as a subsidiary of the SAGE Alliance group under president Lionel Lorier, serving metropolitan France and overseas territories.

The firm's core services comprise regulatory risk cartography (PPRN, PPRM, PPRT), urban planning risk integration (PLU/PLUi), risk engineering (flood, runoff, torrent, mass movement, avalanche), crisis management planning (PCS/PICS), environmental studies and water law documents, and recurring training delivered through IFORE/CVRH, CNFPT, IRMa, and SDIS. Core technical capabilities rest on GIS platforms (ArcGIS, QGIS, MapInfo, GRASS) used since 1991, deterministic physics-based simulation tools (Rocfall 2D, RockyFor3D), and field survey instruments (LIDAR, laser rangefinder, alpine techniques). The firm is not a software vendor; its outputs are professional services.

Revenue is generated entirely through fee-for-service contracts awarded via French public procurement processes, with primary clients being DDT, DDTM, DREAL, DEAL, prefectures, municipalities, and intercommunalities (EPCI). The firm also distributes third-party software (ProGrisk, Cii telecom) as part of crisis management deliverables and operates a wholly-owned subsidiary, Oréade Conseil, for risk communication publications. There is no disclosed pricing, no public rate card, and no software/SaaS revenue stream.

Core offering

Alp'Géorisques is a specialized engineering consultancy delivering natural, mining, and technological risk assessment services to French public sector clients. Its core offerings span regulatory risk cartography (PPRN, PPRM, PPRT), hydraulic and geotechnical engineering studies, crisis management planning (PCS/PICS), environmental impact assessments, GIS-based cartography, and training programs for state personnel. The firm combines field-based 'vérité-terrain' verification with GIS, Rocfall/RockyFor3D rockfall modeling, 1D/2D hydraulic modeling, and LIDAR topographic surveying.

Product overview

Alp'Géorisques est un bureau d'études spécialisé dans l'expertise des risques naturels, miniers et technologiques. Fondée en 1985 et basée à Domène (Isère), l'entreprise propose un portefeuille de services complète de conseil et d'études techniques plutôt qu'un produit logiciel unifié. Son offre s'articule autour de la cartographie réglementaire des risques (PPRN, PPRM, PPRT), de l'ingénierie des risques (hydraulique, torrentielle, mouvements de terrain, avalanches), de la gestion de crise (PCS/PICS), des prestations SIG (ArcGIS, QGIS, MAPINFO, GRASS), de la communication et formation sur les risques majeurs, ainsi que de l'expertise précontentieuse et contentieuse. Les prestations en SIG constituent la composante technologique principale de l'offre, utilisées pour la cartographie et l'analyse spatiale de l'ensemble des risques traités.

Scale indicators3 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Egis: Major French engineering group with environmental, water, and infrastructure practices. Comparable through its environmental impact assessment, hydraulic, and risk-management service lines serving French state and municipal clients.
• Ginger CEBTP: Large French geotechnical and construction-engineering group offering site investigation, foundation engineering, and environmental services. Comparable because it competes with Alp'Géorisques in geotechnical engineering and serves public infrastructure clients, though at substantially greater scale.
• INERIS (Institut National de l'Environnement Industriel et des Risques): French public institute specializing in industrial and environmental risks, including PPRT studies and accidental risk expertise. Comparable to Alp'Géorisques because it operates in overlapping PPRN/PPRT regulatory work and serves French public administration.
• BRGM (Bureau de Recherches Géologiques et Minières): France's national geological survey and a leading public operator of subsurface and natural-risk studies. Directly comparable because it produces regulatory risk cartography, geological expertise, and PPRN/PPRM support for the same DDT/DREAL client base, but at much larger scale and as part of a broader geoscience mandate.
• Antea Group: International environmental and infrastructure consulting firm with significant French operations in water, environment, and risk. Overlaps with Alp'Géorisques in environmental impact studies, water law dossiers, and public-sector consulting.

Direct peers

• Burgeap: French environmental and geotechnical consultancy (part of Egis) providing impact studies, water law dossiers, and site investigations. Closely comparable to Alp'Géorisques in environmental studies, loi sur l'eau work, and public-sector client base.

Emerging players

• Sogelink: French software/data provider specializing in regulatory and risk intelligence for construction and real-estate transactions (including IAL state risk dossiers). Comparable because it serves the same IAL compliance workflow and competes for the digital layer of risk-information delivery.
• Géo-Hyd: Independent French consultancy focused on hydrology, hydraulics, and natural-risk studies for public and private clients. Comparable as a similarly sized niche water-and-risk engineering firm competing for PPRN, hydraulic modeling, and flood-risk studies in France.
