title	BIM quality control based on requirement linked data
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 3, 431–448
summary	This article discusses a BIM Quality Control Ecosystem that is based on Requirement Linked Data in order to create a framework where automated BIM compliance checking methods can be widely used. The meaning of requirements is analyzed in a building project context as a basis for data flow analysis: what are the main types of requirements, how they are handled, and what sources they originate from. A literature review has been conducted to find the present development directions in quality checking, besides a market research on present, already widely used solutions. With the conclusions of these research and modern data management theory, the principles of a holistic approach have been defined for quality checking in the Architecture, Engineering and Construction (AEC) industry. A comparative analysis has been made on current BIM compliance checking solutions according to our review principles. Based on current practice and ongoing research, a state-of-the-art BIM quality control ecosystem is proposed that is open, enables automation, promotes interoperability, and leaves the data governing responsibility at the sources of the requirements. In order to facilitate the flow of requirement and quality data, we propose a model for requirements as Linked Data and provide example for quality checking using Shapes Constraint Language (SHACL). As a result, an opportunity is given for better quality and cheaper BIM design methods to be implemented in the industry.

summary	The ability of GANs to synthesize large sets of data is ideal for coupling with BIM to formulate a multi-access system that enables users to search and browse through a spectrum of articulated options, all personalised to design specificity - an 'Architecture Machine'. Nonetheless, due to challenges in proprietary incompatibility, BIM systems currently lack a secured yet transparent way of freely integrating with crowdsourced efforts. This research proposes to employ blockchain as a means to couple GANs and BIM, with e8 networking topology to facilitate communication and distribution. It consists of a literature review and a design research that proposes a tech stack design and UML (unified modeling language) use cases, and presents preliminary design results obtained using GANs and e8.

summary	In a country with continental dimensions like Brazil, air transport plays a strategic role in the development of the country. In recent years, initiatives have been promoted to boost the development of air transport, among which the BIM BR strategy stands out, instituted by decree n-9.983 (2019), decree n-10.306 (2020) and more recently, the publication of the airport design manual (SAC, 2021). In this context, this work presents partial results of a doctoral research based on the Design Science Research (DSR) method for the application of Machine Learning (ML) techniques in the Artificial Intelligence (AI) subarea, aiming to support SAC airport project analysts in the phase of project evaluation. Based on a set of training and test data corresponding to airport projects, two ML algorithms were trained. Preliminary results indicate that the use of ML algorithms enables a new scenario to be explored by teams of airport design analysts in Brazil.

title	Multi-objective Optimisation of a Free-form Building Shape to improve the Solar Energy Utilisation Potential using Artificial Neural Networks
doi	https://doi.org/10.52842/conf.caadria.2021.1.221
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 1, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 221-230
summary	Optimisation of free-form building design is more challenging in terms of building information modelling and performance evaluation compared to conventional buildings. The paper provides a Photogrammetry-based BIM Modelling - Machine Learning Modelling - Multi-objective Optimisation framework to improve the solar energy utilisation potential of free-form buildings. Low altitude photogrammetry is used to collect the building and site environmental information. An ANN prediction model is developed using the control point coordinates and simulation data. Through parametric programming, the multi-objective algorithm is coupled with the ANN model to obtain the trade-off optimal building form. The results show that the maximum solar radiation value in winter can increase by 30.60% and the minimum solar radiation in summer can decrease by 13.99%. It is also shown that the integration of ANN modelling and photogrammetry-based BIM modelling into the multi-objective optimisation method can accelerate the optimisation process.

title	The Impacts of Collaboration and Cordination of Architectural and Engineering Projects Developed with BIM in Reducing Design Interferences
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 783–794
summary	This paper addresses the importance and development of cultural transformations involving the design process in architecture and the advent of Building Information Modeling (BIM) in civil construction activities and how its implementation in a coordinated, collaborative and interoperable way contributes to a diagnosis of Clash Detection between diferentes design projects, before building construction, saving excessive costs and rework. Taking as its main reference the BIM Maturity Matrix of Succar (2009), the proposed BIM Project Integration Maturity Matrix contributes to the awareness of bringing designers and builders closer to design activities, to encourage the integration of design processes involving the building, to consolidate an environment of ease of communication between participants, the organization of documentation and, above all, prioritize the compatibility between projects to avoid conflicts, excess costs and rework, resulting in a higher quality of the final project.

title	Framework for decentralised architectural design BIM and Blockchain integration
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 2, 157–173
summary	The paper introduces a framework for decentralised architectural design in the context of the fourth industrial revolution. We examine first the constraints of building information modelling in regard to collaboration and trust. We then introduce Blockchain infrastructure as a means for creating new operational and business models for architectural design, through project governance, scaling collaboration nominally to thousands of agents, and shifting trust to the infrastructure rather than the architectural design team. Through a wider consideration of Blockchains in construction projects we focus on the design process and validate our framework with a prototype of BIM design optimisation integrated with a Blockchain mechanism. The paper concludes by outlining the contributions our framework can enhance in the building information modelling processes, within the context of the fourth industrial revolution.

title	Man-Machine Interaction in the Evaluation of Airport Design Process in Brazil
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 742-749
summary	This paper addresses the use of BIM for code verification and automatic validation of the Airports Design (AD). In Brazil, the evaluation and approval of AD are carried out by INFRAERO. Currently, designs are evaluated manually, resulting in errors and long evaluation time. To deal with this problem, a conceptual framework for automated AD assessment with Code Checking is proposed. The method used was Design Science Research, with the proposal of an artifact. The partial results show man-machine interaction as a way more efficient to evaluate the airport design process in Brazil. This man-machine interaction its leads to a mixed model evaluation, with the use of Code Checking for the less complex stages of evaluation and leaving the man responsible for evaluating those more complex, subjective and difficult to implement rules.

title	(Computationally) designing out waste: Developing a computational design workflow for minimising construction and demolition waste in early-stage architectural design
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 4, 594–611
summary	In the architecture, engineering and construction (AEC) industry, waste is oft framed as an economic problemtypically addressed in a building’s construction and demolition phase. Yet, architectural design decision-making can significantly determine construction waste outcomes. Following the logic of zero waste, thisresearch addresses waste minimisation‘at the source’. By resituating the problem of construction wastewithin the architectural design process, the research explores waste as a data and informational problem in adesign system. Accordingly, this article outlines the creation of an integrated computational design decisionsupport waste tool that employs a novel data structure combining HTML-scraped material data and historicbuilding information modelling (BIM) data to generate waste evaluations in a browser-based 3D modellingplatform. Designing an accessible construction waste tool for use by architects and designers aims to heightenawareness of the waste implications of design decisions towards challenging the systems of consumption andproduction that generate construction and demolition waste.

title	Lost in Translation - Achieving semantic consistency of name-identity in BIM
doi	https://doi.org/10.52842/conf.ecaade.2021.2.009

summary	Custom room naming in architectural projects can vary considerably depending on the user. Having multiple and diverse names for the same room is particularly problematic for information retrieval processes in BIM-based projects. Current best practice includes either team agreement on naming labels in BIM or manual renaming to align with an office-wide standard. Both remain laborious and flawed and lead to compounding errors. This research explores how an automated naming-standardization workflow can enhance the interoperability of object-based modeling in a BIM environment and make information retrieval more reliable for a project life cycle. This paper presents research on (1) building a custom corpus specialized for architectural terminology to fit into the BIM environment and (2) devising a standard-naming system titled WuzzyNaming to save manual work for BIM users in maintaining room-name consistency. Our presented workflow applied natural language processing (NLP) technique and Fuzzy logic to perform the semantic analysis and automate the BIM room-name standardization.

summary	Building's spatial structure described in a BIM model can be used for retrieving the information required for determining the shortest path within the building. The matrix method and the visibility method are the two main ways of dividing space into prime factors. Both are widely used to find the shortest path. In order to compare the performance of both methods, several tests were carried out with various versions of the floorplan modification (room area, the surface of internal walls, distance between the entrance, and exit in a straight line and within the boundary marked by walls of the maze). The results revealed significant differences between the visibility graph and the matrix method.

summary	There is a variety of BIM brands present in the Latin American market, there are several questions about their performance in the Spanish language. BIM software companies with a presence in Latin America were appointed to a series of structured and sequenced workshop. At the end of each talk, a specialized audience responded to a series of structured surveys on both theoretical and practical aspects of the software presented. The demonstration consisted of two areas: one theoretical and one practical. The theory presented relevant historical attributes, brand visibility data and some known examples of its use. In the practical part, a live demonstration of the use of the basic tools and functions of the interface was requested. It was derived that: The companies fulfilled the expectation on the agenda in a dissimilar way, the responses to the surveys revealed a similar performance in general terms (modeling, prices), the workshops showed significant differences in theoretical aspects such as known examples, certification. There is a need to advance in the dissemination of the performance of the different BIM brands in the AEC industry in Latin America, the level of individual experience strongly influences the evaluation of the software, the user's profile and the type of project will determine the software to use.

title	Using 3D digital technologies for the documentation and reconstruction of destroyed heritage buildings
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 581-591
summary	Egypt lacks documentation of many of its distinguished heritage treasures, such as artifacts, buildings, monuments and sites. As for the documented component, documents remain in library shelves without much access except for specialists. Much of this documentation has disappeared as a result of neglect, damage factors and various structural repercussions, or as a result of demolition. There is no doubt about the number of heritage buildings that were demolished for city planning purposes, especially in Cairo which possesses more than a third of the traces of the Islamic civilization; a transformationthat is demonstrated by comparing scholar descriptions of the French campaign to Egypt in 1798 and photos taken from the years 1899 to 1920 and beyond, leading to loss of valuable cultural heritage. Therefore, the preservation of this heritage, with the advancement in digital technologies has become one of the important priorities at the international level to confront these problems.Some of the approaches in this regard involve 3D information modeling using either photogrammetry and laser scanning, or 3D modeling and documentation using AutoCAD or 3DMax. This paper addresses the use of Building Information Modeling (BIM) technology in recording, documenting and imagining the reconstruction of heritage buildings, especially partially or completely destroyed heritage buildings, based on written descriptions, pictures or drawings, and the exploitation of technology in the application of virtual heritage, the reconstruction and composition of buildings, structures or artifacts virtually on the computer at fixed epochs. The aim of the paper is to provide a framework to preserve heritage at a lower cost than modern high cost methods, provide a library of its unique architectural elements, revive heritage documents of antiquities, as well as benefiting from their added value in maintenance and restoration operations, and offering data for further studies related to preservation of cultural heritage.

title	Techno-Anthropological Inquiry into VDC Impact on Expert Collaboration in the AEC Industry - Interdisciplinary interactions through Virtual Design and Construction (VDC)
doi	https://doi.org/10.52842/conf.ecaade.2021.1.151
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 151-160
summary	In the architecture, engineering and construction industry (AEC) the transfer of knowledge and information through sharing, cooperation and collaboration serves to manage the inherent complexity of projects. Inter- and transdisciplinary teams including architects, engineers, consultants, contractors, suppliers and building owners, require shared design processes and understanding. Virtual Design and Construction (VDC) is part of how architectural information and knowledge is transferred through integrated processes. As part of an ongoing research this conference paper employs a Techno-Anthropological perspective to map existing research on the subject, to identify research gaps and to suggest further research. Given the ongoing changes the AEC industry is undergoing, we believe that Techno-Anthropology can contribute to systematic analysis and understanding of human-technology interactions. This research examines how VDC impacts upon the output of processes and how it affects the way interdisciplinary teams in AEC industry conceptualize and configure outputs.

summary	As Chinese cities entering a so-called organic renewal era, building projects runs with much more constraints from high-density and high-rise surroundings. Such a situation makes the technical review in any urban planning bureau time-consuming and error-prone, which conflicts with the developers profits and citizens rights. This study introduces a preliminary system being developed for the planning bureau of Huangpu District, Shanghai. It has covered 21 code items among 44 computational ones of the local planning codes last year, which automatically generates technical reviews upon developers submissions. Due to the feasible level of BIM application in domestic projects, a set of strategic approaches, such as the standardization of CAD drawings and the reconstruction of an internal building information model, are adopted rather than developing the system on any BIM platform directly. Two examples of technical reviews about distance-checking between buildings and length-checking of facades are demonstrated, in which officers reached confidential judgments in seconds rather than several days conventionally.

summary	At the time of a global pandemic, risk management in the AEC industry faces novel challenges: to ensure continuity production in worksites, National Governments have defined general protocols. Restrictions regarding individual behaviours are based on criteria as simple as possible but, designing and planning Healthy and Safe (HS) site activities introduces a higher level of complexity to be managed. Narrowing the field to Archaeological buildings, this research aims at defining a method and implementation path for a system supporting HS designers in reducing Covid-19 risk in restoration worksites. Methodologically, an action research approach was adopted, experimenting with some engineering requirements in the case study of the ongoing restoration of "Temple of Venus and Rome" in the "Parco Archeologico del Colosseo" in Rome.Since each scheduled activity assigns a number of actors to a workspace for a time-lapse, the idea is to check HS space classes (e.g. working; resting; paths; storage; etc.) - modelled extending commercial BIM tools - against ad hoc process rules (e.g. maximum presence allowed simultaneously). This early-stage plug-in system evaluates Covid-related safety performance of designed 3D worksite layout versus 4D execution program, eventually providing advice about distancing and physical interferences.

summary	Today's technologies offer exciting new horizons to reconfigure the realm of digital design and fabrication with the use of biologically active materials. Some of the recent works have been exploring the potentials of utilizing biological systems either as mathematical models for digital design or as the material itself in digital fabrication. As one of the novel processes of recent design thinking approaches, this paper presents an example for the collaboration with living organisms and a multidisciplinary process in which the overall structure is based on the analysis of biological material properties, mechanical data acquisition and the integration to digital optimization. In this regard, bacterial cellulose-based composite biofilms were grown and tested for their tensile properties, followed by a proposal to integrate mechanical data to digital optimization for catenary forms to better engage with real world applications. The findings have shown that the use of catenary geometry for such biologically active materials that are relatively novel to the structural use has proven effective for different prototypes thanks to their natural and customized material properties such as the ability to self-stand and biodegrade.

summary	Operating room design is a complex planning task. In order to jointly find the best solution, specialists from numerous professions are involved in the planning process, since e.g. equipment layout and airflow is crucial for optimal surgical procedures. For a better and more informed discussion, and thus better optimization and firm decisions, we have developed a method linking BIM (Building Information Modelling), VR (Virtual Reality), AR (Augmented Reality), CFD (Computational Fluid Dynamics) simulation, and a tangible user interface, so that freely configurable layouts can be tested interactively, be discussed, and optimized both in model and 1:1 scale already in early planning phases. This method has been applied to a hospital design with 33 new operating rooms, differing in sizes as well as layouts according to the different types of operations.

summary	With the rise of the next generation of artificial intelligence driven by knowledge and data, the research on knowledge representation in architecture is also receiving widespread attention from the academia. This paper sorts out the evolution of architectural knowledge representation methods in the history of architecture, and summarizes three progressive representation frameworks of their development with type, pattern and network. By searching these three keywords in the Web of Science Core Collection among 4867 publications from 1990 to 2021, the number of publications in the past 5 years raised more than 50%, which show significant research interest in architecture industry in recent years. Among them, the first two are static declarative knowledge representation methods, while the network-based knowledge representation method also includes procedural knowledge representation methods and provides a way for knowledge association. This means the network representation has more advantage in terms of the logical completeness of knowledge representation, and accounts for 67% of the current research on knowledge representation in architecture. In the context of the rapid development of artificial intelligence, this method can realize the construction of architectural knowledge system and greatly improve the work efficiency of the building industry. On the other hand, in the face of carbon-neutral sustainable development scenarios, using knowledge representation, building performance knowledge and design knowledge could be expressed in a unified manner, and a personalized and efficient workflow for performance-oriented scheme design and optimization would be achieved.
