The company currently employs 40 full-time staff, including 24 highly specialized engineers, 12 draftsmen and 4 administrative.

Several engineers are professors at the Technical University of Madrid and members of various Spanish and International Technical Committees.

The company is organized in two project work-teams led respectively by Prof. Manterola and Dr. Fernández Troyano. The project management responsibility is shared with several senior engineers. Senior engineers managed daily development of the different projects being responsible for:

- Directing appropriate resources to the project.
- Ensuring that progress satisfies the programme requirement.
- Liaising with the client's project manager.
- Meeting the technical challenges of the project.
- Responsible for delivery of the project on schedule.

The technical staff master several languages (English, French, German, Italian and Portuguese), and have experience dealing with international design standards (AASHTO and EUROCODES) as well as the national regulations of several countries (Design Codes in USA, UK, France, Italy, Romania, Mexico, Colombia, Chile, Argentina, Brazil, Venezuela).

The company operates worldwide, either in collaboration with local firms or as member of “design&build” teams with large international engineering and construction companies. The work is done in parallel from the company’s headquarters in Madrid and local offices. Trained engineers of the company are often posted abroad to carry out the development of the projects or to supervise the construction of major bridges.


The key technical personnel involved on the development of the different projects are:

- Miguel Ángel Astiz Suárez (1950), Prof. Dr. Civil Engineer. Full professor of Bridge Engineering at the Madrid Polytechnic University.
- Miguel Ángel Gil Ginés (1949), Prof. Civil Engineer. Lecturer of Bridge Engineering at the Madrid Polytechnic University.
- Antonio Martínez Cutillas (1963), Prof. Dr. Civil Engineer. Assistant Professor of Strength of Materials at the Madrid Polytechnic University.
- Celso Iglesias Pérez (1963), Prof. Dr. Civil Engineer. Assistant Professor of Structural Analysis at the Madrid Polytechnic University.
- Javier Muñoz-Rojas Fernández (1965), MSc. Civil Engineer.
- Lucía Fernández Muñoz (1968), MSc. Civil Engineer.
- Guillermo Ayuso Calle (1973). Civil Engineer.


In addition to its design practice, CFCSL is an active member in construction research and engineering technology, providing several full or visiting professors to the Technical University of Madrid.

CFCSL is also an active fellow in Spanish and European Technical Committees, its engineers regularly participate and attend conferences and workshops of bridge and constructions engineering.

CFCSL was one of the first Spanish engineering companies that incorporated computing tools and that developed software for structural analysis. The majority of the structural software used in daily work is still in-house. Highly experienced engineers contribute to renovate and update the required software.

The R&D technical direction is coordinated by Pr. Dr. Miguel Ángel Astiz Suárez (Madrid 1950), responsible of the software development of CFCSL, is also full professor of Bridge Engineering at the Polytechnic University of Madrid since 2006 where he previously taught Structural Mechanics and Materials Science since 1977. His active academic research involves many features from Engineering Fracture Mechanics, Wind Dynamics and FE Analysis. He is a great expert on static and dynamic wind loads on structures, whose experience has been applied to many of the CFC SL’s long span bridges designs. He has developed many of the structural analysis programmes of the firm, including general modules for 3D structural static and dynamic analysis, prestress analysis, sectional analysis of concrete, steel, and composite sections, general finite elements software.

Miguel Ángel Gil Ginés (Madrid 1949), shares the responsibility of software development. He is lecturer of Bridge Engineering at the Polytechnic University of Madrid, who has developed many structural analysis applications concerning creep and shrinkage effects on structures, steel and composite analysis.

Several others engineers of CFC are involved in the R&D activity to upgrading and improving the in-house structural analysis software.

Current software development involves structure-soil interaction, step by step analysis of creep and shrinkage, non linear analysis of beams and cables, simultaneous stability of large piles, 3D presstress effects, automatic design of slabs with FEM techniques, pre and post-processing applications for an automatic design of standard bridges, …etc.

In addition to the in-house software, CFC SL has advanced commercial programmes of mechanical and structural analysis, among them the finite elements software ABAQUS and SOFISTIK used in very complex and non linear problems. CFCSL was also one of the first Spanish engineering companies that introduced graphic software on its design and drafting work. Design Engineers and Drafting staff handle widespread CAD software as KEYCREATOR, AUTOCAD and MICROSTATION.
