A3D Consulting Integrated BIM Solutions S.L.,

a pioneer in BIM consultancy in Spain, was founded in 2007 by Razvan Gheorghiu Holban.


It was created to meet the need for evolution in a sector stuck in traditional design methodology.


Over these years, it has built up a solid image as a brand with the backing of Spain’s leading engineering and architecture firms.



Focusing at first on offering BIM services to the major architecture studios, it later expanded to the engineering and construction sectors. Recently, it has also moved into the pharmaceutical and facility management sectors.
