Lux. Ouvrage d'Art Sàrl Ingénieurs-conseils

What Lux. Ouvrage d'Art Sàrl Ingénieurs-conseils does

Lux. Ouvrage d'Art Sàrl Ingénieurs-conseils is a Luxembourg-based civil engineering consulting firm (bureau d'étude) founded in 2004 and operating under the trade name Lux Ouvrage d'Art. The firm specializes in ouvrages d'art - bridges, retaining walls, dams, tunnels and quays - delivering engineering studies for government infrastructure owners. Its service portfolio is structured around five interconnected domains: periodic inspection, structural recalculation of existing structures, rehabilitation (with a stated preference for repair over reconstruction), design of new structures and tunnels (including specialized UHPC and carbon-fiber reinforcement work). The firm is led by two Gérants, Fabien Dodeller and Adrien Loiseau, and operates with a team of approximately 10 collaborators comprising consulting engineers, engineers, a technician, drafters/projectors and administrative support.

The company's go-to-market is B2G: engagements are won through public procurement and direct contracting with ministries (Luxembourg's Ministère de la Mobilité et des Travaux Publics, France's Ministère de la Transition Écologique et Solidaire), road administrations (Administration des Ponts et Chaussées, DIR-Est), rail operators (CFL) and municipalities (Ville de Metz / Metz Métropole). Revenue is generated on a project-based professional-services model with fees varying by phase (diagnostic, AVP, PRO, DCE, EXE, DT, VISA, ATE, AOR) and not publicly disclosed. The firm holds ISO 9001:2015 certification since 2022 and is operationally integrated with the Globale Ingénierie group (its email domain is [email protected] and the privacy policy names Globale Ingénierie as data controller).

Since 2020 Lux Ouvrage d'Art has positioned itself for larger projects through a strategic consortium with ICLUX (residential and industrial construction) and Globale Ingénierie (civil engineering project management), supplemented by project-level teaming with RW-CONSULT on rehabilitation mandates. Its delivery philosophy centers on material and economic sobriety, favoring rehabilitation solutions over full reconstruction where structurally viable. Cross-border activity is evident in named French projects (A31 Viaduc de Belleville, A36 Lutterbach, Pont Lothaire Metz), although Luxembourg remains the operational home market.

Core offering

Lux Ouvrage d'Art is a Luxembourg-based civil engineering consulting firm (bureau d'étude) providing engineering studies and project oversight for ouvrages d'art (bridges, tunnels, retaining walls, dams, quays). The firm delivers five core services: periodic inspection, structural recalculation, rehabilitation, reconstruction and new construction design, and tunnel works. Projects are obtained through direct contracting and public procurement with government infrastructure owners in Luxembourg and France.

Product overview

Lux Ouvrage d'Art is a civil engineering consulting firm (bureau d'étude) specializing in ouvrages d'art (art structures) including bridges, retaining structures, dams, tunnels, and quays. The company operates through five interconnected service areas: Inspection (periodic structure inspections), Recalcul d'ouvrages existants (structural recalculation of existing structures), Réhabilitation (renovation prioritizing repair over reconstruction), Reconstruction et projets neufs (new construction design), and Tunnels (tunnel inspection and rehabilitation). This is a single-service architecture focused on engineering consulting rather than a platform-plus-modules structure.

Functional benefit

Products and services

• Inspection (Periodic Structure Inspection) Periodic inspection services for civil engineering structures covering planning, execution, reporting, pathology analysis, and definition of intervention campaigns to ensure the longevity of bridges, retaining structures, dams, tunnels, and quays. Targeted at government infrastructure owners.
• Recalcul d'ouvrages existants (Structural Recalculation) Structural stability recalculation services for existing ouvrages d'art, including reinforcement following pathology appearance, safety norm compliance verification, and calculations for exceptional convoy passage. Targeted at government infrastructure authorities responsible for aging civil structures.
• Réhabilitation (Renovation and Repair) Heavy renovation and rehabilitation services for ouvrages d'art, prioritizing material and economic sobriety. Scope includes guardrail standardization, expansion joint replacement, bridge jack-up and bearing replacement, anti-corrosion protection renovation, and carbon fiber reinforcement. Targeted at government infrastructure owners seeking cost-effective repair over reconstruction.
• Reconstruction et projets neufs (Reconstruction and New Construction Design) Engineering design for new construction projects and for ouvrages too deteriorated for rehabilitation. Covers masonry structures, reinforced concrete (with and without prestressing), ultra-high-performance fiber concrete (UHPC), and steel structures. Targeted at government infrastructure authorities commissioning new bridges, retaining structures, and other ouvrages d'art.
• Tunnels (Inspection and Rehabilitation) Specialized tunnel services for existing tunnels, including inspection, waterproofing and drainage rehabilitation, structural reinforcement, and tunnel head and vault rehabilitation.
