Jerome BTP

What Jerome BTP does

Jerome BTP is an independent French construction company headquartered near Tours (Ballan-miré, Indre-et-Loire) that has operated continuously since 1933. The company delivers integrated civil engineering, utility network, and building construction services across four domains: Génie Civil (reinforced concrete foundations, machine tool supports, retention basins), Réseaux (wet and dry pipe networks for water, wastewater, gas, electricity, and heating), Eau (water treatment stations, drinking water distribution, and the proprietary Régul Fluide macrophyte wastewater process), Énergie (electrical transformer stations and grid infrastructure), and Bâtiment (public buildings and historic masonry restoration). Its technology stack combines traditional construction methods (reinforced concrete, pipe-laying, masonry, stone cutting) with a BIM-capable in-house engineering bureau, specialized underground network detection equipment, and the patented Régul Fluide reed-bed wastewater treatment system deployed in more than 400 French municipalities. The firm maintains ISO 9001, ISO 14001, ISO 45001, MASE, and AIPR certifications, plus Canalisateurs de France Gold (sanitation) and Platinum (drinking water) labels.

The company's revenue model is built on project-based, fixed-price construction contracts ranging from approximately €100–200K to €3M+, with no recurring subscription or licensing streams. Jerome BTP sells exclusively through direct field sales, deploying 15 specialist teams of 3–6 people each from its Tours base across a 400+ km radius, with each project managed by a dedicated Chargé d'Affaires serving as the single point of contact. Its customer base is split across two primary segments: industrial enterprises (Michelin, Compagnie Européenne de Tannage, EQOS Energie, CCCVL nuclear facility) and public/institutional clients (RTE, ENEDIS, GRDF, Tours Métropole Val de Loire, and more than 400 French municipalities). Long-tenured relationships with French grid operators — including nearly 1,000 completed transformer substations for ENEDIS and over 50 years as a certified GRDF gas-network contractor — anchor a recurring base of regulated infrastructure work.

The firm employs 160–170 professionals organized into specialist teams, runs approximately 50 active construction sites at any given time, and invests 4 times the French BTP industry average in training per employee, sustained over 25 years. Jerome BTP has no parent company, no external funding, and no subsidiaries, remaining wholly independent after 90+ years of continuous operation, with a geographic footprint concentrated in the Centre-Val de Loire region and adjacent markets.

Broad incumbents

• Colas (Bouygues): World-leading road construction and infrastructure group. Adjacent rather than direct in Jerome BTP's water/energy focus, but overlapping in earthworks, civil infrastructure, and public-sector client relationships.
• Eiffage Construction: Major French construction group with broad infrastructure, energy, and concessions operations. Overlaps with Jerome BTP in civil works and energy network construction but operates at national/international scale with a much wider portfolio.
• Bouygues Construction: Large French general contractor covering building, civil works, and energy/infrastructure projects. Comparable in nonresidential building and heavy civil engineering segments, but with multi-billion-Euro scale and global footprint.
• Vinci Construction France: French arm of Vinci's construction division, active in civil engineering, road infrastructure, and utility networks. Directly competes in civil/utility tenders but at a national scale that overshadows regional contractors.

Direct peers

• NGE: Multi-disciplinary French civil engineering and infrastructure contractor with strong positions in networks, earthworks, and energy infrastructure. Comparable in offering breadth, customer mix (public + private), and mid-sized regional operational model.
• Sade: French specialist contractor in water, wastewater, and utility network construction, wholly owned by SUEZ. Directly comparable to Jerome BTP's Réseaux secs et humides and Eau business lines for municipal and industrial clients across France.
• Sources: French water and environmental infrastructure contractor specializing in drinking water, sanitation, and wastewater treatment works. Closely comparable to Jerome BTP's Eau portfolio and small-to-medium commune customer base.
• Razel-Bec (Fayat Group): French heavy civil engineering contractor within the Fayat group, active in earthworks, underground networks, and energy infrastructure. Comparable in civil/utility construction activities and grid-operator contracting, particularly for ENEDIS/RTE-adjacent work.
• Spie Batignolles: Major French general contractor covering civil engineering, infrastructure, and building construction. Directly comparable in business model mix (Génie Civil, Réseaux, Bâtiment) and public/private client coverage, though at significantly larger scale.
• Léon Grosse: Independent French construction group with operations in building, civil engineering, and infrastructure. Comparable in integrated offering (Bâtiment + Génie Civil + Réseaux) and family-owned independent operating culture.
