Computational Platform

Building Information Modeling (BIM) can store information of building elements and provide a computational platform for physical analyses for building systems. BIM can resolve several problems throughout various phases of design (as well as construction and operation). While use-cases such as daylight or energy analysis widely take advantage of this computational power, there is no integrated acoustical analysis tool or any external programs with acceptable interoperability within the BIM ecosystem. This study investigates the possibility of developing a BIM-based calculation method based on the most widely used design authoring tool in North America, i.e., Autodesk Revit, to estimate the acoustical properties of buildings with acceptable accuracy and details. A novel algorithm is designed to calculate reverberation time (RT), one of the most critical acoustic indicators of building spaces. The algorithm extracts geometric information from the BIM (i.e., the model); matches it with the physical properties provided by an open-source library; performs the analysis; visualizes the results on the model. The tool is tested over several case studies, and the results have been verified and validated using other existing methods. In the paper, we have studied the acoustical properties of an educational building using the designed tool under various scenarios.

Prefabricated Building

The adoption of prefabricated building systems has grown due to the need to reduce duration and cost of construction projects, as well as to improve quality and working conditions. However, the adoption of those systems requires an intense exchange of information to integrate the production of components, logistics operations, and site assembly. This is particularly important in engineer-to-order environments, in which the level of uncertainty tends to be high. This research proposes a model for planning and controlling the delivery and assembly of ETO prefabricated building systems, emphasizing the integration between site installation and logistics operations. This model was devised in an empirical study carried out in a company that delivers and assembles prefabricated concrete structures. The main theoretical contribution is a set of approaches to implement the “pull production” and “reduce variability” principles in this particular context, exploring synergies that exist between Lean Production principles and Building Information Modeling (BIM) functionalities.

Building Information

Thanks to its capability of archiving and organizing all the information about a building, HBIM (Historical Building Information Modeling) is considered a promising resource for planned conservation of historical assets. However, its usage remains limited and scarcely adopted by the subjects in charge of conservation, mainly because of its rather complex 3D modeling requirements and a lack of shared regulatory references and guidelines as far as semantic data are concerned. In this study, we developed an HBIM methodology to support documentation, management, and planned conservation of historic buildings, with particular focus on non-geometric information: organized and coordinated storage and management of historical data, easy analysis and query, time management, flexibility, user-friendliness, and information sharing. The system is based on a standalone specific-designed database linked to the 3D model of the asset, built with BIM software, and it is highly adaptable to different assets. The database is accessible both with a developed desktop application, which acts as a plug-in for the BIM software, and through a web interface, implemented to ensure data sharing and easy usability by skilled and unskilled users. The paper describes in detail the implemented system, passing by semantic breaking down of the building, database design, as well as system architecture and capabilities. Two case studies, the Cathedral of Parma and Ducal Palace of Mantua (Italy), are then presented to show the results of the system’s application.

First Time

Currently, the innovation agenda of the industry professional and academic community in the information and conceptual plans is largely filled with topics related to Building Information Modeling (BIM) technologies. In this sense, often, in a different context, we are talking about several new "digital" subject areas for the qualitative development of creation technologies, united by the new convergent paradigm "Smart City". For the first time, the general logic of convergent modeling of the "Smart City" is presented, the key target priority of which is the new socio-technological paradigm "Urban Health" at the level of relationships between the entity models "Smart City" and the results of their convergence. At the same time, it is shown that practical problems at the functional level of designing building systems today are solved, as a rule, using a wide range of modern automation technologies, and solving problems at the cognitive level of the complex effects of creative activity requires the use of technologies and techniques with elements of artificial intelligence.

Pros And Cons

“Change or perish. You need to prepare yourself for a profession that you are notgoing to recognize a decade from now.”Thom Mayne, Remarks on building information modeling at the 2005 AIAConvention, Las Vegas, NVToday architects are faced with new challenges involving Integrated Project Delivery and associated digital technologies that are rapidly changing the way architects work. Collaboration is the key to this newway of working as architects discover that the management of buildinginformation requires new skills and methods in design.How do educators respond to this call? How do we prepare a futuregeneration of architects to thrive within a rapidly changing profession?Given these new models for project delivery currently being utilized by theprofession, a new pair of courses was created at the Southern CaliforniaInstitute of Architecture (SCI_Arc) for the integration of the designcurricula with a building technology course by emphasizing teamworkand the use of three-dimensional software. The aim was to develop newskill-sets for students while maintaining a deep understanding of designand built form. Educators have long struggled with traditional architectural curricula that inherently separate design and technology courses. This bifurcation, often times convenient and useful for the organization of aschool and curriculum, is of course at odds with the “comprehensive” nature of architectural education that is so strived for in most programs.This paper serves to show examples of an attempt to address this seriousissue within the first professional graduate school curriculum (3 1/2 yearM.ARCH) by bridging both the second year design and technology classesover a two semester span. The goals of the two courses were; to bridgethe gap between design and technology pedagogy, develop collaborativetools for students, investigate a comprehensive understanding of theintegration of building systems, and to finally produce a set of documentsthat demonstrate this ability and use appropriate three-dimensionalsoftware to facilitate the investigation.It is helpful to set the stage on the importance of this shift of educational methodology by outlining first the context of the current environment bothwithin the profession and the academic realms. Finally, I will attempt toreflect on the methods employed and analyze the pros and cons of theendeavor and discuss possible improvements.

Building information modeling-based construction networks (BbCNs) are teams from several professional organizations working together to assume building information modeling- (BIM-) related assignments on BIM-enabled projects. With a view to achieving a better understanding of the knowledge domains on integration in BbCNs, a systematic mixed-method review of the relevant studies published from 2008 to 2018 is conducted in this study. An “integration pentagon” made up of context, process, organization, task, and actor is used as a theoretical lens to identify and construct knowledge maps describing the integration in BbCNs. The study conducts a comprehensive review upon a bibliometric analysis based on 1019 researches into BIM and a qualitative analysis of 42 carefully selected researches into integration in BbCNs. The findings confirm that the solutions provided by these researches to support integration in BbCNs are altogether technology oriented. The sociotechnical dimensions including context, organization, task, and actor show limitations. More importantly, the major academic contributions of the study lie in offering an objective and systematic analysis of previous researches, revealing the gaps on integration in BbCNs, and advising researchers in future studies regarding the integration pentagon as an all-inclusive analysis tool. These results highlight the status quo of BbCNs knowledge and serve as a dynamic platform to allow other scholars to perform further developments of integration in BbCNs.
