Structure-Concept

What Structure-Concept does

Structure-Concept is a French structural engineering consultancy (bureau d'études bâtiment) headquartered in Mulhouse, Haut-Rhin, France, founded in 1992 and operating as a SARL unipersonnelle under sole ownership of Damien MANARA, who also serves as President and lead project engineer. The firm employs 10 staff—3 engineers and 7 technicians with individual professional experience ranging from 3 to 40+ years—and delivers structural engineering, BIM coordination, construction economics (quantity surveying), VRD (site infrastructure and exterior works), and structural diagnostics services. Its client base spans public sector project owners (communes, communautés de communes, departmental authorities, and mixed-economy companies) and private developers (housing associations such as NEOLIA and Mulhouse Habitat, healthcare operators including Muta Santé, industrial firms, and entertainment operators including Cinécroisière and Groupe Barrière). Service delivery geography is anchored in the Haut-Rhin department (68), with recent realized projects in departments 90 (Territoire de Belfort/Delle), 88 (Vosges), and 39 (Jura).

The firm offers multi-material structural engineering covering reinforced concrete (béton armé), metal framing (charpente métallique), traditional timber, and glued-laminated timber (lamellé-collé) construction in a single integrated practice. Its workflow stack includes Autodesk Revit Structure for BIM Level 2 and 3 project conception, Tekla Structures Diamond for metal framing, Robot Structural Analysis for finite element and dynamic/seismic calculations, Strakon for reinforcement detailing, MDBAT and CADWORK for timber, IDEA STATICA for metal connections, and Devisoc for cost estimation and technical prescription, with IFC-based interoperability through Tekla BIMsight, Navisworks, and DynamoBIM. A Hilti Ferroscan PS 200 S supports non-destructive reinforcement mapping in concrete elements for diagnostic and renovation pre-project work. The team holds experience with French environmental building certifications including RE 2020, EnerPhit BaSE, Passive Level, Biosourced Building, and Qualitel/Effinergie labels.

Structure-Concept generates revenue through project-based professional service fees, with engagement typically extending from early design collaboration with architects through project plans, execution studies, and construction supervision. The portfolio includes more than 60 documented realizations across sports and leisure, public buildings, social and healthcare, industrial, tertiary, residential, and photovoltaic categories, with notable projects including the Technocentre (€16M passive rehabilitation of a former foundry), a 7-screen multiplex cinema for 975 spectators in Cernay (€5M, delivered December 2021), the Hôtel communautaire de Lure (€5.52M, the largest local timber building in Haute-Saône), the MECS children's home in Ottmarsheim (€10.97M), the EHPAD healthcare facility (€21.6M, delivery 2026), the Casino Barrière Espace Balnéo (€18M), and the restructuring of Collège Kennedy in Mulhouse (€9.13M). The firm markets and distributes through its corporate website (www.structure-concept.com) and direct B2B contact, with no intermediary or reseller distribution model, and is currently actively recruiting a reinforced concrete design technician on a permanent CDI contract.

Revenue model

1. Structural Engineering Studies: Conception, optimization and study of reinforced concrete, metal, and wood structures. Static load calculations, 3D and dynamic calculations, stability and seismic analysis. Project and execution plans for concrete, reinforcement, and nomenclatures. Revenue generated through professional service fees for engineering studies.
2. Construction Economy / Quantity Surveying: Technical specifications and cost studies for all building trades (excluding fluids): material selection, budget elaboration, technical specifications, environmental and energy performance requirements, tender dossiers, bid verification, and construction contract assistance.
3. VRD (Infrastructure and External Works): Site development, roads and networks, and exterior arrangements as part of overall project services.
4. Structural Diagnostics: Diagnosis of building structures and building envelope (excluding thermal), providing reliable pre-project assessments for building transformation projects. Includes reinforcement scanning and concrete bearing capacity determination.
5. TCE (All Trades) Project Management: Full all-crafts project management and construction supervision, e.g., the multiplex cinema project where Structure Concept piloted the entire TCE construction.

Core offering

Structure-Concept is a French building engineering consultancy that designs and calculates structural systems in reinforced concrete, metal, and wood for public and private building projects. It delivers structural conception, optimization, 3D BIM modeling, construction economics/quantity surveying, VRD (roads and external works), and non-destructive structural diagnostics, serving project owners from early design through execution plans and construction supervision.

Product overview

Structure Concept is a building engineering firm (bureau d'études) specializing in structural engineering for construction projects in the Haut-Rhin region of France. The company operates as a single unified service offering rather than a platform-plus-modules architecture. Their core offerings include Structural Engineering Services (conception and calculation of concrete, metal, and wooden structures), BIM Services (3D project design using Revit Structure), Construction Economy services, VRD (civil engineering), Structural Diagnostics, and Execution Plans. These services are delivered through a team of 3 engineers and 7 technicians and are applied across diverse project categories including sports facilities, public buildings, healthcare/social facilities, industrial buildings, tertiary sector, housing, and photovoltaic installations.
