The company is established as an electrical installation company under the name “Instalaciones Eléctricas Constantino Zapico García” by Constantino Zapico García. At that time, the field of activity only encompasses the region of Asturias.


Aquilino and Jesús María Zapico, sons of Constantino Zapico, found the installation company IPEZSA (Instalaciones y Proyectos Eléctricos Zapico S.A.), to give continuity to the work that their father has been developing since 1964.


Two years later, IPEZSA execute the project for the electrical installation of the Civil Guard headquarters in El Rubin, Oviedo, for the building company Agroman. This is a turning point for IPEZSA.


IPEZSA moves to a new facility in the Industrial Area of Riaño-I. The engineering company SAZEPI is also established that same year, to provide IPEZSA with technical support in response to their increased workload.
