The di.FM (Digital for Facility Management) protocol is an innovative approach for maintenance management, through the creation of a digital twin interconnected to the existing building. The goal is to create a BIM model that is constantly updated on the state of the building, therefore capable of collecting related information and monitoring the state of use of the elements and components present.

The relationship between complex form and manufacturing efficiency is increasingly important in light of the remarkable development of digital manufacturing techniques. Algorithmic modelling has assumed a central role as it is able to satisfy both aesthetic and production needs.

The application of parametric software for the executive design of future façades is oriented to structure the project reality and develop communication tools for the production and construction phases, according to an adequate representation of the complexity of contents.

Some positive results in experience using VR for Autism show potential for inclusion and communication with the aim to achieve a communicative instrument useful for all. Compared to the previous researches this study focuses on the human answers to technology finding new design guidelines for an autism friendly VR.

The three-dimensional modelling, aimed at the representation of urban contexts, is closely linked to the theme of communicating information related to the constructive, typological and technological characteristics of the historic city. In particular, the definition of methodological protocols for the creation of extended 3D models is at the center of the research developed in Bethlehem by DAda-LAB Didactics and Research Laboratory of University of Pavia.

The analysis of an exemplary case study is the pretext to critically examine the validation procedures of BIM- oriented projects of considerable complexity, through the description of operational strategies that allow to control and preserve the quality of reusable graphic-alphanumeric attributes even during the life cycle of the product.

The current situation of AECO sector is challenging Universities in bridging the gap between skills required from the market and current qualified capabilities of young professionals. The real innovation is in the definition of new rules both for teaching and evaluating, considering the importance of new evaluation criteria and focusing on the digital value of education.

Dealing with processes, digital tools and their application in the design and construction of a building means working with many acronyms that identify micro or macro-topics, areas or disciplines and at the same time, perhaps for their very nature, that generate various interpretations and some misunderstandings.

One of the first and most important acronyms, widely spread in the 1980s and then discussed for more than twenty years, is the acronym CAD and its intrinsic dualism between Computer Aided Drafting and Computer Aided Design. This dualism – which can be considered outdated as well as unsolved – was interpreted as Computer Aided Architectural Design (CAAD) and Computer Aided Design and Drafting (CADD) depending to different authors and contexts.

The most recent and popular acronym is BIM (Building Information Modeling). Depending on the context, it can be understood at the same time as a process, as a set of digital tools or as the result of both. In BIM there are many other acronyms subject to interpretations. Just to make an example: LOD (Level of Development) vs. LoMD (Level of Model Definition) that is the integration of LoD (Level of Detail) and LoI (Level of Information). Both now should migrate to LoIN (Level of Information Need). The term “Level” is often used in various ways and it is sometimes misunderstood.

It is what it is.

This trend will pass as many others and we will have clearer ideas in a few years…

This article does not propose definitions, which would stratify uselessly on others and could be the starting point for others again. It does not even intend to provide clarifications on the “BIM thing” which is in continuous transformation.

In this article, the word BIM will appear using italics, and telling what the author learned in recent years, addressing the digitization of information in the processes of design and construction of bespoke facades, built internationally, in very different markets.
