    Bridges and structures

    Our projects are based on smart, attractive, efficient and enduring designs. We are experts in carrying out projects in complex areas, such as those which are earthquake prone or unstable, creating innovative solutions to cover all kinds of needs.


Practical, innovative and sustainable designs

Since Ayesa was founded, one of our main areas of work has been the calculation and design of structures. Thanks to our more than 55 years of experience, we are able to cover all aspects of these projects relating to civil, industrial and building engineering.

Over the years, we have become somewhat of an authority when it comes to designing conventional and unique railway and road bridges, and carrying out calculations for all kinds of projects, including underground solutions for metro systems and vehicles, as well as industrial, hydraulic and environmental structures. We also have extensive experience designing all types of foundations and renovating structures. What’s more, we offer technical assistance and construction management services for these kinds of projects. Our work around the globe has given our technical teams the tools they need to adapt designs and projects to all applicable local laws, regulations and codes governing structures, in addition to expertise on the most commonly used structural calculation programmes in each country.

We offer high-quality solutions designed to meet the needs of clients all over the world, something made possible by a technical team made up of experts from different fields and countries. At the heart of their approach is an eagerness to acquire and share knowledge that adds value to our projects. Of all the projects we have undertaken over the years, our aseismic solutions particularly stand out. We have extensive expertise in these types of designs, having worked in some of the most earthquake-prone regions in the world.

Our team offers a wide range of solutions and possibilities when it comes to structural projects, and is able to meet all kinds of requirements. What’s more, our work is based on cutting-edge techniques, tools and ideas, the result of our extremely varied experience in the field. However, that doesn’t mean we don’t strive to ensure our designs respect tradition, make full of use of existing resources and fit in with their surroundings. Our structural experts are based in various offices and involved in workaround the world, meaning we're never far from our clients.
