What Carlos Fernandez Casado does

Carlos Fernández Casado S.L. (CFCSL) is a Madrid-headquartered civil engineering consultancy founded in 1964 by Professor Carlos Fernández Casado and his disciples Javier Manterola Armisén and Leonardo Fernández Troyano. The firm specializes in the design and supervision of bridges, viaducts, footbridges, large structures, and transport stations, covering every project phase from feasibility studies and preliminary design through construction project development and independent construction supervision. Its work spans all major bridge typologies — cable-stayed, extradosed, arch, suspension, gantry, and beam — in concrete, steel, and mixed construction, and includes world-record-breaking structures.

The company serves almost exclusively public-sector clients: national, regional, and local government infrastructure authorities as well as rail-infrastructure developers (e.g., ADIF, APILAC, Govern d'Andorra, Government of Cantabria, National Roads Authority of Ireland). Marketing and client acquisition operate through technical publications, academic affiliations with Universidad Politécnica de Madrid, and participation in national and international technical committees, rather than traditional demand-generation channels. Pricing is not publicly disclosed and is consistent with professional engineering services engagement — quote-based contracts against government and institutional procurement.

Since 2025, CFCSL has been integrated into the ARX group while retaining its specialized brand and project office identity. Operationally, CFCSL remains a boutique 11–50-person firm with a global project footprint across Spain, Italy, Ireland, Andorra, Romania, Bulgaria, the United States, Mexico, Colombia, Peru, the Philippines, China, and Iran, demonstrated by ongoing or recently delivered projects including the Gordie Howe International Bridge (US/Canada), New Harbor Bridge (Texas), Viaducto Conagua (Mexico), Cebu-Cordova Bridge (Philippines), and the central highway in Peru.

Broad incumbents

• HDR: HDR is a US-headquartered engineering, architecture, and consulting firm with a dedicated bridges and structures practice serving DOTs and federal agencies. Comparable as a public-infrastructure-focused bridge design firm but operating at substantially greater scale.
• WSP: WSP is a major global engineering professional services firm with a substantial bridges and structures practice serving public clients worldwide. Overlaps with CFCSL on bridge design commissions but operates at much greater scale across multiple infrastructure verticals.
• Arcadis: Arcadis is a global design and engineering consultancy with bridge, rail, and mobility capabilities serving government clients. Competes with CFCSL on public-sector infrastructure mandates as part of a broader design, engineering, and consulting portfolio.
• Mott MacDonald: Mott MacDonald is a large global engineering consultancy with extensive bridge and highway infrastructure capabilities across transport, rail, and water. Competes with CFCSL on large public-infrastructure tenders but as part of a much broader multi-disciplinary portfolio.
• Buro Happold: Buro Happold is an international engineering consultancy with strong structural and bridge engineering capabilities alongside buildings, energy, and environment practices. Comparable as a high-end structural engineering firm pursuing signature infrastructure projects.
• COWI: COWI is a Danish engineering consultancy with a leading global bridges practice (e.g., Storebælt, Øresund) and broad infrastructure footprint. Comparable to CFCSL on long-span signature bridges but with significantly larger scale and geographic reach.

Direct peers

• Schlaich Bergermann Partner: Schlaich Bergermann Partner (sbp) is a German structural engineering firm renowned for innovative bridges, cable-stayed structures, and lightweight roofs. Closely comparable niche specialist in advanced bridge typologies and academic-driven engineering, similar in size and reputation to CFCSL.
• Arup: Arup is a global engineering consultancy with one of the world's leading bridge and structural engineering practices, working on signature crossings worldwide. Directly comparable to CFCSL in delivering complex bridge design and supervision, though at far greater scale and broader scope.

Lin International is a global infrastructure consulting firm specializing in bridge and structural engineering, with a strong portfolio of cable-stayed and long-span bridges. Highly comparable specialist competitor to CFCSL on signature bridge projects across the Americas, Asia, and Europe.

Emerging players

• Studio Santiago Calatrava Valls: Calatrava is an architecture and engineering studio famous for iconic, sculptural bridges and station structures worldwide. Comparable to CFCSL in delivering signature, architecturally distinctive bridge designs, but competes from an architecture-led rather than pure-engineering position.
