What TRANS-FAIRE does

TRANS-FAIRE is a French environmental and urban planning consultancy founded in 2002 by Philippe Beros and headquartered in Arcueil (Paris) with a second office in Marseille. The firm delivers integrated AMO (Assistance à Maîtrise d'Ouvrage) and MOE (Maîtrise d'Œuvre) services — French project-management and design-engineering modalities — across the full lifecycle of urban development and construction projects: co-production/stakeholder engagement, planning, pre-operational studies (site analysis, environmental impact assessments, Natura 2000, protected species, authorization), operational phase, and certification. The company's offering is augmented by proprietary internal tools: the natotem biodiversity framework (positioning nature as a proactive urban totem rather than a compliance burden), CartoSE for ecosystem services mapping and statistical analysis (applied to the Paris 2024 Olympic Athletes' Village), and EcoChantier for real-time environmental monitoring on construction sites.

The firm serves a roughly 50/50 mix of public and private clients, including urban developers and property developers (aménageurs, promoteurs), local authorities and semi-public companies (SEM), and infrastructure operators such as Groupe ADP. Revenue is generated through engagement-based professional services billing, with no public pricing tiers and a free half-hour videoconference used for initial commercial scoping. Marketing is primarily content- and relationship-driven: a weekly LinkedIn newsletter, on-site field visits for complex projects, and the TRANS-FAIRE Club — a client-exclusive training and exchange network that supports retention and cross-selling. Geographic reach is France-wide with selected international engagements (European OLGA airports programme).

The team consists of approximately 15 multidisciplinary professionals including ecologists, engineers, architects, urban planners, designers, and spatial-data specialists (GIS, algorithms). The company maintains certified expertise across HQE, BREEAM, BiodiverCity, Effinature, ISO 14001, RE 2020, and E+ C- standards, and operates active R&D collaborations including a PhD thesis with UMI-SOURCE on multidimensional sustainability indicators and a partnership with Folléa-Gautier on DREAL PACA's Plaine de la Crau ERC territorialisation project. The firm is privately held, founder-controlled, with no disclosed external investors.

Broad incumbents

• Egis: Large French engineering group with dedicated environment, biodiversity, and urban-development practices. Competes for the same AMO/MOE mandates TRANS-FAIRE targets but offers one-stop-shop delivery including transport, structural, and project-management scopes beyond TRANS-FAIRE's niche.
• Suez Consulting (SAFEGE): Environmental and water consultancy arm of the Suez group offering environmental impact assessments, permitting, and biodiversity services to public and private clients. Overlaps with TRANS-FAIRE on environmental consulting for urban and infrastructure projects at significantly larger scale.
• Setec Group: Major French engineering consultancy with environment and urban-development capabilities, including setec environnement. Targets similar aménageur and local-authority clients for environmental and AMO work, with substantially greater resources.
• Ingérop: Independent French engineering consultancy with environmental, urban, and infrastructure practices. Overlaps with TRANS-FAIRE on environmental permitting, impact studies, and AMO roles for public-sector clients, but competes from a broader multi-discipline platform.
• Artelia: France-based international engineering and project management group with a built-environment and environment division. Competes in the same urban-development and environmental-consulting space as TRANS-FAIRE but at much greater scale and with broader multi-disciplinary delivery.

Direct peers

• Altereo: French environmental and urban-planning consultancy delivering environmental assessments, biodiversity studies, and AMO services to public-sector clients. Comparable niche positioning and project mix to TRANS-FAIRE in the French environmental consulting market.
• Atelier Folléa-Gautier: French landscape architecture and urban-environmental design firm with comparable AMO/MOE positioning on urban development and biodiversity projects. TRANS-FAIRE is an actual partner on the DREAL PACA Plaine de la Crau ERC territorialisation mandate, evidencing direct overlap in scope and client base.
• TERAO: French environmental and energy consultancy specializing in sustainable building, urban planning, and AMO/MOE environmental quality services. Closely comparable in scope (HQE/BREEAM support, environmental project management) and target clientele (developers, local authorities) to TRANS-FAIRE.
• Burgeap: French environmental and geotechnical engineering consultancy (subsidiary of Egis) offering environmental impact assessments, permitting support, and biodiversity studies for urban and infrastructure projects. Comparable service mix to TRANS-FAIRE but operating at significantly larger scale and with broader engineering depth.
• Biotope: Leading French independent environmental consultancy specializing in biodiversity, ecology, and natural-resource assessments for infrastructure and urban development projects. Directly comparable to TRANS-FAIRE on biodiversity/environmental consulting for aménageurs and public authorities, though with a larger footprint and broader ecological scope.
