We are an engineering firm specialising in complex installations that is committed to sustainability and innovation.We are aware of our responsibility to contribute to a better world and of the needs of our clients to accomplish their objectives.

“We are a company with values adding value”

We are increasingly immersed in a VUCA (volatility, uncertainty, complexity and ambiguity) environment in which technological development has seen exponential growth.

As a result, the market demands agile companies capable of adapting to emerging needs and prepared to function in an ongoing state of learning, in order to provide their clients with the best knowledge and possible solutions.

Due to the importance of providing sustainable solutions for the preservation of the environment, in 2023 we began a union process with the energy and sustainability consultancy ERF to build together a solid business project.


Protecting the environment in the context of a global and competitive market requires specialist companies with technical knowledge and the ability to adapt effectively and create strategic partnerships.


To provide knowledge, innovation and quality services with a high added value, in order to improve safety, people’s wellbeing and protect the environment, throughout the engineering and consulting process. From Barcelona to the world.


Knowledge, trust, commitment, empathy, innovation, environment, professionalism, proximity and quality.

The company

ARCbcn was founded in 2012 through the merger of Armengol Enginyers and RC & Crespo Enginyers. The name ARCbcn was inspired by the word “ARC” and represents the coming together of the two names. It is also a symbol of connection and a fundamental engineering concept.

Our many years’ experience has made us a leading company, well-known in Barcelona, in the fields of engineering, installations consulting, legal consulting, energy and environment consulting and R+D projects.

ARCbcn has a desire to take its knowledge and company values from Barcelona to the world. In view of this ARCbcn works with a network of partners across the planet to facilitate knowledge sharing and added value.
