ADAM Travaux Publics

What ADAM Travaux Publics does

ADAM Travaux Publics is a privately held French civil-engineering and public-works contractor headquartered in Bouxwiller, Alsace (Grand Est). Founded in 1946 by Louis Adam originally as a transport and fuel-sales business, the company was converted into a Société Anonyme with public-works activities and is now structured as a Société par Actions Simplifiées (SAS) under the direction of PDG Olivier Zentz. With 29 employees, it delivers six service lines — terrassement, voirie, assainissement, eau potable, dépollution, and travaux publics / génie civil for réseaux secs — to municipalities (collectivités) and private developers (entrepreneurs privés) across Bas-Rhin, Lorraine and neighbouring departments.

The company's technical stack centres on GPS-guided terrassement machinery for precision earthmoving, supported by an in-house independent soil and material analysis laboratory that validates environmental compliance and informs project planning. It holds public authorisations for transport and provisional storage of polluted soils and extends its dépollution offering through a partnership with Céterra for on-site and in-situ remediation techniques. A wholly-owned subsidiary, Hanau Recyclage, supplies recycled aggregates (GNT1, GNT3) used in terrassement works. The firm operates within the Zénith union of companies, which pools member capacity to enable bids on larger projects.

Revenue is generated on a project-by-project basis through direct contracts and competitive bidding, with no publicly disclosed pricing. Documented project scale includes single contracts moving 115,000 m³ of material (SEW USOCOME Forbach extension) and delivering 70,000 m² of platform construction (Reichstett Ecoparc Rhénan). Quality credentials include ISO 9001 (v2000) and ISO 9002 certifications, Labels Canalisateurs de France Eau et Assainissement (2008, 2009), and Palmarès des Entreprises distinctions from the Ordre des Architectes (2009, 2010).

Direct peers

• NGE (Nouvelles Générations d'Entrepreneurs): French independent multi-specialist public works group covering earthworks, roads, utilities, environmental remediation and civil engineering. Closest comparable to ADAM in service-line breadth, with the same union-of-companies operating philosophy scaled nationally.
• Ramery: Family-owned French public works and environmental contractor with multi-trade capabilities (terrassement, VRD, dépollution, réseaux) across northern France. Closely mirrors ADAM in family stewardship, regional footprint and integrated service offering.
• Demathieu Bard: Independent French construction group operating in building, civil engineering, earthworks and utilities. Comparable on private/family ownership profile and multi-specialist public-works execution, though larger in scale.
• Léon Grosse: Family-controlled French construction group active in building, infrastructure and earthworks. Comparable to ADAM through its family-ownership structure and direct execution of public-works lots, though with a much broader geographic and service footprint.

Broad incumbents

• Eurovia: Vinci subsidiary specialised in transport infrastructure and urban development, including earthworks and utilities. Direct overlap with ADAM's voirie and réseaux secs activities but operating as part of a global group.
• Colas: Bouygues-owned global road construction and public works leader. Competes with ADAM on voirie and terrassement bids in Alsace but at a fundamentally larger scale and cost base.
• Spie Batignolles: Major French multi-specialist contractor covering civil engineering, earthworks, utilities and environmental works. Overlaps with ADAM's service lines but operates as a national incumbent rather than a regional specialist.
• Eiffage Travaux Publics: Infrastructure arm of the Eiffage group, active in roads, earthworks, civil engineering and utility networks. Bids into the same public-sector framework contracts as ADAM in eastern France.

Regional players

• Roger Martin: Regional French TP generalist acquired by NGE, with comparable earthworks, road and utility capabilities but historically concentrated in Bourgogne-Franche-Comté rather than Alsace.

Emerging players

• Sade (Veolia subsidiary): French specialist in water and sanitation network construction and rehabilitation. Direct overlap with ADAM's assainissement and eau potable service lines, typically as a subcontractor or specialist partner on utility lots.
