“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.

We are a part of the WATTEGA business union, whose main objective is to accelerate the ecological transition through innovation and techno-scientific knowledge, together with the energy and sustainability consultancy ERF, because we recognize the need to provide sustainable solutions for the preservation of the environment.


To be a reference in the sustainable transformation of organizations, built spaces and territories.

Our Story

The two companies, Armengol Enginyers and RC & Crespo Enginyers merged in 2012 to form ARCbcn. It has become a reference point in the innovation ecosystem and one of the leading facilities engineering companies in the Catalan region, particularly in Barcelona, in just ten years. At the moment, ARCbcn is in charge of managing two significant EU-funded initiatives across Europe.

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.

In 2023, ARCbcn has taken its most ambitious step and joined forces with the ERF – Energy & Sustainability consultancy to create a solid business project; WATTEGA.
