Lamoureux & Ricciotti Engineering

What Lamoureux & Ricciotti Engineering does

Lamoureux & Ricciotti Engineering (LRING) is a French private engineering consultancy (Bureau d'Études Techniques) founded in 2005 by Romain Ricciotti and Guillaume Lamoureux, headquartered in Paris with offices in Bandol and Marseille. The firm provides integrated structural engineering (Génie Civil/Structure) and building envelope engineering (Enveloppe du Bâtiment) services, with a distinct specialization in Ultra High Performance Concrete (UHPC/BFUP) and the regulatory pathway for innovative construction (ATEx). It also offers adjacent capabilities in prefabrication, off-site construction, BIM coordination, heritage rehabilitation, special structures, and engineering for nuclear, maritime, and military facilities.

The firm's core technology is centered on materials science and structural methodology rather than software. Its practice encompasses world-first UHPC applications, including the all-UHPC MUCEM building in Marseille (2013) and the Pont de la République road bridge in Montpellier (2014), plus over 50 successful ATEx (Technical Experimentation Assessments) for innovative construction. Tools and methods include BIM for collaborative design, life cycle analysis, 2D/3D prefabrication and dry construction, 3D concrete printing for 5G telecommunication masts, and R&D in material reuse (BFUP waste, stone, brick). The team of 11-50 is composed of engineers trained at top French institutions (ENPC, Polytechnique, ESTP, INSA) supplemented by international education backgrounds (Aarhus, Glasgow, Dublin Institute of Technology).

LRING operates a project-based, quote-driven business model typical of French BETs, with services delivered directly to architects, developers, and public authorities. Revenue is generated through master builder (maître d'œuvre) and BET structure missions on bespoke engineering contracts. The firm serves a horizontally diversified set of use cases — cultural institutions, commercial/office, education, infrastructure, sports facilities, residential, hospitality, and specialized nuclear/maritime/military projects — primarily across France with international project work in Monaco, Brazil, USA, Italy, Czech Republic, and Belgium. The firm is founder-owned and privately held, with no disclosed institutional investors, funding rounds, or acquisitions.

Broad incumbents

• Egis: Large French engineering group covering transport, buildings, energy and urban development with in-house structural engineering that overlaps with LRING's infrastructure and building scope at much greater scale.
• Bureau Veritas Construction: Global testing, inspection and certification group with French construction-services operations overlapping LRING's technical-control, ATEx and diagnostic/heritage workstreams.
• WSP France: Global professional services firm with French structural and building-envelope teams serving cultural, transport and commercial clients, competing for larger versions of LRING's project types.
• Arup (Paris): Global engineering consultancy with a major Paris office delivering structural, façade and material-innovation work on landmark projects; broader portfolio but competing for the same complex and innovative-material commissions as LRING.

Direct peers

• Setec TPI: French structural engineering consultancy (part of the setec group) providing structural studies, BIM and complex-project engineering across buildings and infrastructure in France; overlaps directly with LRING's core structural and innovative-materials missions.
• Artelia: French-headquartered multi-disciplinary engineering consultancy with building, infrastructure and industrial practices offering structural design and project management comparable to LRING's BET missions.
• Bollinger + Grohmann: Franco-German structural engineering consultancy with a strong reputation for innovative materials (timber, concrete, UHPC) and complex façades, closely comparable to LRING's envelope and structural specialization.
• Buro Happold: International engineering consultancy with strong structural and façade practices known for innovative materials and complex geometry, a close functional analogue to LRING's specialist BET model.
• Schlaich Bergermann Partner (sbp): German structural engineering firm specializing in innovative long-span, bridge and lightweight structures using high-performance materials; directly comparable to LRING's innovative-structure and UHPC bridge work.

Others

• Holcim (LafargeHolcim) Solutions & Products: Major cement and UHPC producer (including Ductal AF) whose material offerings and engineering-partner programs intersect with LRING's material expertise; relevant as an industrial collaborator and adjacent enabler rather than a direct BET competitor.
