Sisba

What Sisba does

Sisba is a privately held French structural engineering firm (cabinet d'études structure béton) headquartered in Clisson, Loire-Atlantique, founded in 2008 by Nicolas Colinet and Matthieu Peltier. The firm delivers reinforced concrete structural engineering services across conception, execution, diagnostic, seismic analysis, BIM, and carbon footprint assessment missions for architects, maîtres d'ouvrage (property owners), engineering firms, and construction contractors in the Pays de la Loire region. As of the most recent reference points, the team comprises 9 collaborators including 3 project managers, 4 draftsmen, 1 BIM Manager, and 1 management assistant.

Sisba operates on a project-based professional services model, executing both public tenders (Marché Public type loi MOP) and private commissions with fees determined per project scope. The underlying technology stack centers on Autodesk Revit for BIM (Building Information Modeling) — adopted firm-wide by 2017 — supplemented by Advance Design for finite element analysis and seismic modeling, and ADEME methodology for carbon footprint assessment. The firm has committed company-wide to open BIM standards through its Building Smart France membership and maintains the OPQIBI certification (1202) for standard concrete structures, which is uncommon for firms of its size.

The firm's competitive positioning relies on a small but experienced team (leadership with 15–20+ years in structural engineering), regional ecosystem embedding through NOVABUILD cluster membership since 2013, and incremental service expansion into low-carbon construction (Bilan Carbone) and seismic studies. Its market scope is primarily regional — Loire-Atlantique, Vendée, Maine-et-Loire, and Sarthe — with occasional projects extending into adjacent departments. Geographic expansion beyond this base is minimal and there is no external institutional investment.

Broad incumbents

• Egis: Major French engineering and infrastructure consulting group with significant building and structural capabilities. Competes for public and private structural mandates at scales well beyond Sisba, while serving the same architects/owners.
• WSP: Global professional services consulting firm with an established Buildings practice in France including structural engineering and BIM services, competing for mid- and large-scale mandates.
• Tractebel (ENGIE): Large engineering consultancy under ENGIE with active practice in building, energy, and infrastructure. Comparable at the consulting/engineering service layer though vastly larger in scale and geographic scope.
• Ginger Group: French engineering and environmental services group operating across construction, environment, and infrastructure. Provides broader subspecialties than Sisba but competes directly on structural and concrete engineering assignments in the French market.
• Bureau Veritas: Global TIC group with significant building and construction services in France, including structural assessment and code compliance verification. Operates in adjacent but overlapping territory with diagnostic and expertise work.
• Arcadis: Global design and engineering consultancy with a French practice spanning building, mobility, and resilience. Addresses the same architect/owner ecosystem with a broader service portfolio.
• SOCOTEC: French TIC (testing, inspection, certification) leader with a strong construction risk management and diagnostic practice. Adjacent competitor for structural diagnostic and expertise mandates.

Direct peers

• INGEROP: French engineering consultancy active in building, energy, transport, and urban development. Competes for structural engineering mandates on mid-size public and private construction projects similar to Sisba's portfolio.
• Setec: Independent French engineering firm covering buildings, infrastructure, and industrial projects. Overlaps with Sisba in structural engineering services and BIM-led delivery for architect/owner teams across France.
• Artelia: French independent engineering and project management consulting group with strong building, structural, and infrastructure practices. Comparable to Sisba in mission types (conception, execution, BIM, diagnostics) and direct engagement with architects and maîtres d'ouvrage, though materially larger.
