The essay deals with some issues related to CAAD (Computer Aided Architectural Design) and BIM (Building Information Modeling) analyzing the specificity about the historical condition on main theoretical references. We consider some significant contributions, including those by Nicholas Negroponte and William J. Mitchell regarding CAAD and Charles M. Eastman on BIM.

Building Information Modelling (BIM) is a collaborative approach to the building process. The goal is to test BIM for Facility Management (FM) by defining the Levels of Development (LODs), worksharing and data visualization for process optimization.

This research describes the author’s experience in the design of the collaborative spaces of the Apple iOS Developer Academy (Naples). The intent is to explore the new frontiers of BIM using algorithmic tools to manage the formal and informative features of the project.

The new UMC headquarter introduces in the company a new process matching the FCA (Fiat-Chrysler) guidelines compliance (building designed as “shop windows” with wide curtain walls surfaces, which needs HVAC and MEP oversizing) with building and maintenance rationalisation cost asked by the client, facing the environmental and energy sustainability in a very challenging climate by LEED approach.

The BIM process, based on a parametric model connected to a complex and interactive database, leads to a new collaborative approach between the operators involved. Through the case study, the current technologies for the use of information are also tested on site, in order to streamline management and maintenance.

The knowledge of landscape is a fundamental element to operate in Architecture, Engineering and Construction (AEC) industry. This contribution aims to analyse current and innovative approaches to get territorial data in order to design a City Information Modeling (CIM) making use of open geospatial data and geospatial surveying.

Our research analyses the potentialities and critical aspects resulting from the integration of BIM systems in the processes of survey, communication and management of the Built Cultural Heritage (BCH). It deals with the conceptual extension of “virtual model” triggered by BIM approach and its possibilities of stratifying knowledge.
The potential of BCH-oriented BIM systems (the so-called Heritage-BIM or H-BIM) is undeniable. However, there remain operational and theoretical issues related to the unresolved aporia between the rigidity of modelling tools and the high flexibility needed when BCH elements are involved.
Supported by some test applications carried out on case studies belonging to Sapienza main campus, our research aimed at defining a comprehensive approach for the implementation of BIM in the consolidated processes of survey, mainly referring to massive capturing technologies.
In the transition from the numeric model (point cloud) to the geometric one (synthetic and structured at semantic level too) this paper discusses the introduction of a new parameter, the Level of Reliability (LOR). This new factor intends to measure and explain the consistency of digital objects resulting from critical analysis and re-elaboration activities.
Current vagueness of standards together with the need for transparency in H-BIM modelling processes has led to the LOR as a possible solution to preserve the geometric correspondence and the ontological reliability of the model vis-à-vis the artefact it intends to represent. It describes, in fact, the level of global coherence of the process defining each element of the model and the model as a whole. The coding of a set of common and shared parameters makes it possible, finally, to achieve a synthetic numeric evaluation of the LOR, a sort of “score” for the model.
In this framework, the Level of Reliability may perhaps represent a relevant methodological step forward to “customize” BIM systems in order to make them more compatible with BCH issues. In other words, to encourage, support and implement the consolidated approaches that imply the gradual and deep knowledge of artefacts as a precondition for their conservation and enhancement.

The redevelopment of the Cotral station of Ponte Mammolo, is outlined as a winning action under several points of view. The first project, concerns the renovation of a degraded area; the second is the successful experimentation of the integration between the traditional modeling of the architectural artefact and the work in the BIM field for the management of the building site and the construction costs.

Following the Italian LD 50/2016 (known as “New Public Procurement Code”), and subsequently the Italian LD 560/2017 (known as “Decree BIM”), interoperability between different programs for Building Information Modeling has become a growing issue, discussed among operators in the construction sector. This is highlighted also by the very frequent discussions on forums and chats among users of different software.
This paper aims at contributing in clarifying the concept of interoperable platforms, open formats and export in compatible formats. Besides pointing out at the very frequent misunderstandings, it illustrates the difficulties met while trying to integrate data linked to models created with different software. The study shows how interoperability is a problem which in practice is much more complex than declared at theoretical level.

The aim of the work is to show how the application of the computational design can speed up and improve the realization of complex geometries typical of historical architecture and automate some processes in the design phase. The object of the research is the building housing the Cento art gallery (Pinacoteca Guercino), damaged by the seismic events of May 2012.
