Ianus (Janus) is “the god of beginnings and transitions, and thereby of gates, doors, doorways, passages and endings. He is usually depicted as having two faces, since he looks to the future and to the past. (…) As a god of transitions, he had functions pertaining to birth and to journeys and exchange, and in his association with Portunus, a similar harbor and gateway god, he was concerned with travelling, trading and shipping.” (fonte: Wikipedia)

He is the two-faced god par excellence, who is able to look to the past and the future. The past of that which men or nature have built, and the present of the technologies (such as laser scanners) that allow us to study and preserve it for future generations.

Ianus is a cooperative of professionals originating from the need to integrate and network varied competences and experience, converging on techniques and ways of understanding architecture and the surrounding space.
We are interested in studying architectural works, archaeological remains, the land itself, developing a clear organizational strategy and producing descriptive materials effective and useful for different clients. 
This includes, but is not limited to, metric surveys.

Our knowledge is acquired through the analysis of the evolutionary history of a building, through a direct stratigraphic reading of vertical surfaces and an indirect analysis of historical and archival sources. 
We use photography to document the work environment and create high-quality, metrically-correct photo plans. 
We are able to identify instabilities and deformations within a structure, the materials used in the construction, and the form and extent of degradation present.

Thanks to the support of specialized partners, we can perform archaeological surveys, i.e. surveys that are integrated with excavation work and document findings and progress of the work (many websites confuse archaeological surveys with surveys of archaeological sites).

Derived from our expertise, the activities of Ianus are:

Architectural survey
Archaeological survey
Structural survey
Critical Survey
Territorial Survey

We use the most appropriate technology for each case study, from terrestrial laser scanners and total stations to Barton combs; professional digital cameras, organizational and processing software. 
Ianus is composed of five offices positioned in five cities: Cagliari, Verona, Siena, Pisa and Paris. 
With a collective leadership, typical of a cooperative organization, which deals with economic and strategic choices, the local branches complement each other in planning and carrying out projects thanks as well to an extensive network of associates. 
Each office is headed by one of the partners and operates with a spirit of collaboration and fusion of staff and experience. 
Each office also offers different services locally in the fields of architecture and engineering (design, project management, authorization from supervising bodies, safety practices, and appraisals).
