The degree of Building Engineering deserves an earnest and thorough study with the aim of participating in the definition of future professional powers that should be granted by the legislature, since as of today it has only received the same authorities as those granted to Architectural Technologists.This analysis is based both in the length of the university studies that the new graduates have to carry out in order to obtain the degree (4 years), exceeding in one year those executed by Technical Architect (3 years), as well as on the new professional profiles comprised in the White Book of the Building Engineer and the new fields of expertise established in the Order ECI/3855/2007.As a result of the study an extension proposal is obtained, containing 14 new professional responsibilities.
