Since its beginning Carlos Fernández Casado, S.L. has had an active international presence and has taken part in numerous projects all over the world.

Our international activity was initially focused on South American countries. However, it has gradually expanded to encompass virtually every continent.  Our projects can currently be found in:

  • European Union: Spain, UK, France, Italy, Portugal, Ireland, Romania, Bulgaria and Andorra
  • South America: Chile, Argentina, Uruguay, Brazil, Ecuador, Bolivia, Colombia, Panama, Peru and Venezuela
  • North and Central America: Mexico, Puerto Rico, Dominican Republic, Cuba, Honduras, Canada and USA.
  • Asia : Qatar, Iran, India, Korea and China
  • Africa:  Morocco.

CFCSL is covered by international insurance contracts to ensure that any legal or civil liability issues may be solved within the scope of our international activities.



Our firm operates internationally developing projects in cooperation with local consulting firms or international engineering firms.  We have worked alongside with top Spanish consulting firms (SENER, TYPSA, Eptisa, Eyser, Getinsa, Técnicas Reunidas, etc.) as well as with major international groups (COWICONSULT (Denmark), ARUP (UK), HNTB (USA), Yooshin Corporation (Korea), etc).

We also participate in construction projects with major international general contractors and building groups (Dragados, OHL, FCC, Sacyr). Within this field we have maintained a longstanding collaborative relationship with the Mexican firm MEXPRESA, with which we have specialised in designing special bridges in Latin America (cable-stayed, incrementally launched and moveable bridges).

The headquarters of our firm is located in Madrid, Spain, where our team of expert engineers develop their work. However, depending on the demands of each particular project it is customary to send designer engineers or supervising engineers to provide on-site project development and supervision or work with local engineering firms.
