“MENSURA EST MODUS IN RES BIM AEDIFICATORIA AEDIFICATORIA” MEASUREMENT IS THE CONSTRUCTION MODE VIA BIM

Abstract. The BIM method allows to include topography and remote sensing in important way: it is a continuous dynamic, in itinere, not only before the construction but, also, as design verification, after the construction. Understanding the right level of BIM to use is necessary in order to obtain an Opera constructed exactly as was it designed; and to manage the BIM process during the entire construction. This paper supports a precise thesis: the concept of "measure" as a way of implementing BIM. "Measuring" does not only means exchanging data, between design phase and construction phase but, also, identifying accuracy, reliability, , tolerance, modus operandi, "level" of BIM. Identifying and measuring this level is the “way of BIM”, since the design, during the building site work, until the opera's delivery. Predefined ways of applying BIM do not exist it depends on the type of work, context, people, equipment, times and resources, including the human skills. Our research group was asked to support two projects. A public work: the Navy Academy recovery; and a private work: the monitoring via BIM-GIS of the technical components laid in the building site.
