CTH INGENIERIE

What CTH INGENIERIE does

CTH INGENIERIE is a French engineering consultancy and construction-management firm (bureau d'études et maîtrise d'oeuvre) founded in 2013 by Stéphane Hansen. Headquartered in Grasse with a satellite agency opened in Toulon in 2022, the firm operates across the Alpes-Maritimes, Var, Bouches-du-Rhône and broader PACA / Southern Alps region, serving both public-sector clients (communautés de communes, communes, conseils généraux) and private-sector clients (property developers, companies, ski resort operators such as Isola 2000 and La Colmiane, and individuals). Three internal divisions structure the offer: Pôle Travaux Publics (roads, earthworks, utilities networks, urban planning), Pôle Montagne et Environnement (ski infrastructure, snow-making, hydraulic and environmental engineering), and Pôle Topographie (GPS, 3D surveys, drone aerial photography). Supporting service modules span Conception (feasibility, terrain surveys, 3D visualization), Démarches Réglementaires (water law, deforestation, hydraulic dossiers, building permits, sanitation), and Travaux (tender management, on-site supervision and warranty follow-up).

Revenue is generated exclusively through professional-services fees on project-based engagements, sourced through public tenders for government clients and direct commissions for private clients. Headcount grew from a sole founder to four collaborators by 2013, to eight employees by 2022, and annual revenue exceeded €1M as of 2018 with a 230% business-volume increase in 2017. The firm holds French Ministry of Environment ministerial approval (agrément) for the auscultation, analysis and design of dikes, dams and water retention structures, and operates its own field surveying brigade equipped with a Leica TS 13 autonomous motorized total station, Leica GS08 GPS (1 mm precision), and professional drones capable of 300 m HD aerial photography. The company is privately held and founder-controlled, with no disclosed institutional investors, funding rounds, or parent entity.

Customers named in the data include the Communauté de Communes du Haut Verdon Val d'Allos, the Communes of Allos, Ascros, Rouret, La Gaude and Escragnolles, Valsophia Immobilier, Isola 2000 and La Colmiane ski resorts. Distribution relies on direct field sales and public procurement processes, supported by presence on LinkedIn, Instagram, Facebook, and earned media in regional publications (Nice Matin, Le Moniteur, Montagne Leaders). Growth has been entirely organic and self-funded, with strategic milestones including the 2015 acquisition of GREN, the 2019 Grasse headquarters relocation, the 2018 ministerial approval, and the 2022 Toulon agency.

Core offering

CTH INGENIERIE is a French engineering consultancy and master work (maître d'oeuvre) bureau operating across three divisions: Public Works (roads, networks, urban planning), Mountain and Environment (ski resorts, hydraulic structures, environmental compliance), and Topography (GPS, 3D, drone-based surveying). The firm delivers feasibility studies, design, regulatory dossiers, and construction supervision for public-sector clients (municipalities, communities, departmental councils) and private clients (developers, businesses, individuals) primarily in the Southern French Alps (PACA region).

Product overview

CTH INGENIERIE is a multidisciplinary engineering and construction management firm operating three core service divisions: (1) the Public Works Division handles road infrastructure, earthworks, structural works, landscaping, and utility networks; (2) the Mountain and Environment Division specializes in ski resort development, snow-making systems, environmental engineering, and hydraulic infrastructure; and (3) the Topography Division provides surveying, GPS mapping, and drone-based aerial photography services. Supporting these divisions are three service modules covering design (feasibility, 3D visualization), regulatory permitting (environmental compliance, water law), and construction management (tendering, site supervision, quality control). The company serves both public clients (municipalities, intermunicipal communities) and private clients (developers, individuals, businesses).

Broad incumbents

• SAFEGE (Suez): French engineering consultancy specializing in water, environment, and infrastructure, part of the Suez group. Comparable in delivering hydrology, hydraulic, sanitation, and urban-network engineering services to public-sector clients in France.
• Egis: Large French engineering group operating across transport, infrastructure, water, and environment consulting. Comparable as a French multi-disciplinary engineering consultancy overlapping in public-works, hydraulic, and environmental project management — but at significantly greater scale and geographic reach than CTH.
• Antea Group: International engineering and environmental consulting firm with strong French operations in water, soil, and environmental project management. Comparable in providing environmental dossiers, hydraulic/hydrology studies, and project supervision to municipalities — adjacent to CTH's regulatory and environmental services.
• Setec: France-based engineering group working on infrastructure, water, environment, and urban development projects. Comparable as a French maître d'oeuvre engineering consultancy delivering feasibility studies, regulatory dossiers, and construction supervision to public and private clients.
• Ingérop: Independent French engineering firm providing consulting, project management, and turnkey delivery in infrastructure, environment, and energy. Comparable in acting as maître d'oeuvre on civil-works and environmental projects for public-sector clients and in handling regulatory/dossier work similar to CTH.
• NGE (group): Major French public-works contractor and concession operator with in-house engineering capabilities for road, utility, and earthworks projects. Comparable at the execution/construction interface: although CTH is non-executing master work, NGE represents the type of large contractor CTH supervises and coordinates with on public-works tenders.
• Artelia: Major independent French engineering consultancy covering construction, mobility, energy, water, and environment. Comparable in offering engineering and project-management services to public authorities and private developers across France, including water-law and hydraulic dossiers similar to CTH's mountain/environment division.

Others

• Géomètre-Expert firms (Ordre des Géomètres-Experts network): Network of French chartered surveying firms offering topographic, GPS, drone, and 3D surveying services. Comparable to CTH's Topography division in delivering GPS measurements, earthworks 3D surveys, and as-built surveys used in construction supervision.

Direct peers

• Cabinet Merlin: French independent engineering consultancy specializing in water, environment, and river/coastal infrastructure, with ministerial hydraulic approvals. Comparable as a niche French engineering bureau of similar size profile focused on hydraulic studies, water-law dossiers, and water-retention structures — overlapping directly with CTH's ministry-approved dam/dike work.

Emerging players

• Cluster Montagne members (various mountain engineering cabinets): Cluster of French mountain-sector businesses, of which CTH is a member. Member firms span mountain engineering, ski-resort development, and snow-making/ski-piste design — comparable as fellow specialized mountain-infrastructure consultancies and potential collaborators or sub-contractors in adjacent territories.
