title	An open, integrated modular format: For flexible and intelligible architecture, engineering and construction design and production
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 1, 23–36
summary	The architecture, engineering and construction sector is fragmented, and its computer-aided design systems suffer data loss and errors in workflow between design and realisation. An open source, integrated, modular format is proposed to address the technological nature of these problems. Accordingly, this research updates the notion of the modular format as a more flexible and intelligible computational design method by leveraging knowledge from the computer science and manufacturing sectors where the design and realisation process is intentional and explicit. The research design of this article comprises a theoretical approach combined with an empirical case study. Principles of modularity are extracted from the computer science and manufacturing sectors to assist with a better definition of architecture, engineering and construction computer-aided design processes that use materials and resources more efficiently and sustainably. The methodology of the modular format contributes to the emerging concept of a building lifecycle management system for the architecture, engineering and construction sector.

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	Safety Information Modelling to Support Planning of Archeological Restoration Site - Preserving workers from COVID-19 at "Venus and Rome Temple"
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 77-86

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	This practice-based research presents insights into the potential and challenges for augmented and mixed reality (AR/MR) technology to enhance Australian small-to-medium (SME) custom manufacturers’ agility to overcome existing Industry 4.0 (I4.0) workforce productivity and efficiency challenges. Moreover, it seeks to understand the technology’s ability to support custom manufacturers and the architectural, engineering and construction (AEC) sector transition to a more human-centric Industry 5.0 (I5.0) model, whereby the well-being of the fabricator is placed back at the centre of manufacturing processes. This qualitative study draws on interviews with eleven Australian custom manufacturing industry professionals to inform pertinent themes around fabricators’ current use and perceptions of mixed reality technology. Results indicate benefits for fabricators in reducing 2D drawing and task-related ambiguities in fabrication and assembly practices and reveal factors surrounding underutilisation. Synthesising insights and reflecting on Teixeira et al., (2021)’s XR-PACT framework, key research areas are identified for future AR/MR development centred on fabrication users’ distinct needs to improve accessibility, empower fabricators and ultimately assist the competitiveness of custom manufacturers and the AEC sector.

summary	The emerging video game industry has provided opportunities for innovation and transformation starting with the late 20th century. In line with ever-changing needs and increasing demand, the extent of the digital gaming industry has outreached to the education sector and its subdomains besides the entertainment industry and its sub-branches as users obtain ambidextrous achievements through the gamification processes in which an experimental learning environ-ment is formed naturally. Numerous dissimilar disciplines from en-gineering, architecture, construction, work safety, renewable ener-gy, education, and health, etc. train users thru educational simula-tions prepared in digital environments to amplify their learning processes. Undoubtedly, the fields of architecture, engineering, and construction (AEC) are gradually adapting to the conditions of ac-celerating digitalization efforts in this era. Thus, BIM technology being one of the common denominators of the digitalization efforts in those fields serves the diverse agenda of the users with increas-ing popularity. Professional interaction and education may greatly benefit from conjoining the model outputs of BIM technology and interactive visual fidelity of the digital gaming industry. This ongo-ing research project aims to develop and compare two different BIM-based models of the historic Çardak Khan and the contempo-rary student center building by creating sophisticated digital game environments with architectural educational space-based informa-tive scenarios. Space-based virtual cards were created for each sce-ne. Research results in response to the diversity of spaces, geomet-ric qualities, number of scenarios and sequences were reported. Fur-thermore, textual data such as game scripts and drafts were ana-lysed with Voyant Tools.

summary	Desertification has made large productive landscapes in the South-west Thar desert redundant, subjected people to migration and induced a constant influx of sand into the region (Singhvi and Amal, 2014). The abundance of sand creates an opportunity to adopt an existing technique, Bio-mineralisation, to develop a sand based composite material which, when treated with a construction binder like sodium alginate, can be used for engineering purposes. The paper sets a theoretical framework to develop a fabrication mechanism with microbial-grout injections and propose the development of in-dune/underground assembly of habitable spaces. Each of the sub-components of material system, fabrication mechanism and In-dune structures are detailed, and evaluated to devise a hierarchy between them. Their interdependencies together inform design strategies, a phasing plan and global time scale for overall terrain transformation.

title	Human-Computer Interaction for Urban Rules Optimization
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. 603-613
summary	Faced with the complexity of manual and intuitive management of urban rules in architectural and urban design, this paper offers a collaborative and digital human-computer approach. It aims to have an Authorized Bounding Volume (ABV) which uses the best target values of urban rules. It is a distributed constraint optimization problem. The ABV Generative Model uses multi-agent systems. It offers an intelligent system of urban morphology able to transform the urban rules, on a given plot, into a morphological delimitation permitted by the planning regulations of a city. The overall functioning of this system is based on two approaches: construction and supervision. The first is conducted entirely by the machine and the second requires the intervention of the designer to collaborate with the machine. The morphological translation of urban rules is sometimes contradictory and may require additional external relevance to urban rules. Designer arbitration assists the artificial intelligence in accomplishing this task and solving the problem. The Human-Computer collaboration is achieved at the appropriate time and relies on the degree of constraint satisfaction with fitness function. The resolution of the distributed constraint optimization problem is not limited to an automatic generation of urban rules, but involves also the production of multiple optimal-ABV conditioned both by urban constraints as well as relevance, chosen by the designer.

title	Simultaneous effect of form modifications and topology of the bracing system on the structural performance of timber high rise building - Introducing an innovative approach using parametric design

summary	Topology optimization is a tool that minimizes the material consumption in a structure, while at the same time provides us design alternatives integrating architectural and structural engineering concepts. However, topology optimization is a structural engineering subject and its known methods are required professional knowledge of engineering to be used. In this article, the mutual effect of form modifications and topology of the bracing system in a 9-story timber exoskeleton high-rise building regarding the governing wind load and seismic load is examined. What differentiates this study from former ones and in fact its main purpose is introducing an innovative approach towards structural topology optimization using parametric design. In this innovative approach, the possibility of moving for each central node of bracing systems in defined ranges independently and the possibility of the existence or absence of each bracing member is provided. This parametric model will enable architects to optimize the topology of the structural elements which are part of their architectural design by themselves. The CMA-ES-algorithm-based optimization is done to minimize both total mass of structure per unit area and the horizontal displacement of the top floor. For modeling, optimizing cross-sections and structural analysis, Grasshopper and its plug-in called Karamba are utilized.

summary	This paper presents a study developed in the scope of an ongoing research about the creation of an architectural design system of low-cost housing in Portugal's context. Its goal is to present the survey, analysis and digitization work of a research carried out in the 1960s by Portuguese architect Nuno Portas, with the help of architect Alexandre Alves Costa. The method was to convert mathematical information contained in Portas' and Alves Costa's report from Lisbon's National Laboratory of Civil Engineering (LNEC) into an algorithmic model with Rhinoceros® and Grasshopper® software. Besides revealing for the first time a comprehensive study of this pioneering work, this paper will set the foundations to propose the adaptation of its process into low-cost housing design. The result presented here is an algorithm for selecting the best architectural type from a database of housing floor plans, analyzed by a questionnaire regarding the inhabitants' needs and satisfactions.

summary	3D printing offers significant geometric freedom and allows the fabrication of integral parts. This research showcases how robotic fused deposition modeling (FDM) enables the prefabrication of large-scale, lightweight, and ready-to-cast freeform formwork to minimize material waste, labor, and errors in the construction process while increasing the speed of production and economic viability of casting non-standard concrete elements. This is achieved through the development of a digital design-to-production workflow for concrete formwork. All functions that are needed in the final product, an integrally insulated steel-reinforced concrete wall, and the process for a successful cast, are fully integrated into the formwork system. A parametric model for integrated structural ribbing is developed and verified using finite element analysis. A case study is presented which showcases the fully integrated system in the production of a 2.4 m tall x 2.0 m curved concrete wall. This research demonstrates the potential for large-scale additive manufacturing to enable the efficient production of non-standard concrete formwork.

summary	This study explores the educational use of Augmented Reality (AR) for teaching Three-Dimensional Graphic Geometry (GGT) within the Engineering curriculum at the Federal University of Pernambuco. GGT course faces high failure rates due to students' spatial skill limitations and struggles with visual comprehension. To address this, the GGT-RA app was developed, enabling real-time visualization of 3D models from the course ebook using AR. A survey evaluated impressions, yielding insights for app improvement, with feedback from students, teaching assistants, and professors during remote 2021 usage. While the application has shown promise, forthcoming improvements should place a priority on ensuring compatibility across devices and enhancing system flexibility. This will improve accessibility and facilitate understanding of 3D Graphic Geometry for students.

summary	In recent years, additive manufacturing and 3D printing technologies have been increasingly used in the field of construction engineering. 3D Concrete printing is a kind of laminated printing method using concrete extrusion technique. Concrete has the advantages of high compressive strength, low deformation, and excellent durability, and has high application value in the construction field. However, as a brittle material, concrete has limited tensile and flexural strength. For beam like components, it is difficult to fully exert the compressive performance of the material relying solely on itself, so it is difficult to apply to the bending member. The experimental case introduced in this paper combined the prestressing system with concrete printing technology. A post-tensioning prestressing system suitable for prefabricated concrete 3D printing components, which combined the excellent tensile properties of steel bars with the compressive performance of the 3D concrete printed part was proposed.

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	This paper aims to define the concepts, methods and techniques needed to establish a multifaceted, yet comprehensive description of complex problems facing conventional architectural design, and how to decode the problems knots through integration between techniques and technologies in generative algorithmic and its impact of the quality of design solution. To attain these aims, the study explores the ability of integrated algorithmic techniques in developing dealing with complicated problems in the design of museums exhibition halls. It discusses, analyzes, and evaluates several conventional architectural design methods and reviews the challenges that limit their ability to produce creative solutions. This will help close the gap between the design quality and duration of design process; conforming that engineering programs help designers, not marginalize them. And hence developing architectural considerations in the design process to parametric paradigms that are suitable for scientific curriculum. So, the research problem is how such methodology can implement the integration between generative design techniques.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 24-32.
summary	The construction industry faces numerous challenges related to productivity, sustainability, and meeting global demands (Hatoum and Nassereddine 2020; Carra et al. 2018; Barbosa, Woetzel, and Mischke 2017; Bock 2015; Linner 2013). In response, the automation of design and construction has emerged as a promising solution. In the past three decades, researchers and innovators in the Architecture, Engineering, and Construction (AEC) fields have made significant strides in automating various aspects of building construction, utilizing computational design and robotic fabrication processes (Dubor et al. 2019). However, synthesizing innovation in automation encounters several obstacles. First, there is a lack of an established venue for information sharing, making it difficult to build upon the knowledge of peers. First, the absence of a well-established platform for information sharing hinders the ability to effectively capitalize on the knowledge of peers. Consequently, much of the research remains isolated, impeding the rapid dissemination of knowledge within the field (Mahbub 2015). Second, the absence of a standardized and unified process for automating design and construction leads to the individual development of standards, workflows, and terminologies. This lack of standardization presents a significant obstacle to research and learning within the field. Lastly, insufficient training materials hinder the acquisition of skills necessary to effectively utilize automation. Traditional in-person robotics training is resource-intensive, expensive, and designed for specific platforms (Peterson et al. 2021; Thomas 2013).

summary	This paper examines the suitability of existing robotic technologies and large-scale 3D printing techniques for the fabrication of three-dimensional printed building components to be applied in the Saudi housing construction industry. The paper assesses a series of cases based on the applications for 3D-printing cement-based materials in construction. In particular, we investigate five different additive manufacturing techniques and evaluate their performance in terms of their flexibility/mechanism, control/navigation, calibration/operation system, fabrication suitability (in-situ or off-site), size of printed components, printing speed. The findings include in a matrix chart, where the advantages and disadvantages of each technique become evident. The paper further evaluates the suitability of each technique in relation to the particular climatical and socio-political context of Saudi Arabia, applicable to other construction industries with similar conditions.

summary	Evolutionary Algorithm (EA) are optimization techniques that can improve measurable performances of a design. Currently, they see many research interests and are advertised, among generative design, as the next big thing in architecture by some software house. However, they still see limited professional use. This paper, through the analysis of past researches and a case study on an architectural envelope’s shadowing system design, reflects on the reasons for this and on how the use of EA influences the product and the process of architectural design. Also, methodological principles to suit the use of EA in an architectural design process are discussed.

summary	Daylighting provision gives a significant contribution to the enhancement of the indoor visual environment and user comfort. This study aims to provide a methodology to assess and optimize daylighting performance in buildings. The paper utilizes simulation techniques for identifying the most efficient daylight performance by incorporating parametric optimization tools to enhance the daylighting performance of existing buildings. The developed workflow includes three consecutive phases. The first examines the daylighting performance of the existing building. The second phase is concerned with daylighting adequacy and the third aims to optimize the quality of light rather than just the quantity through the utilization of a simple shading system to parametrically investigate the effect of using different shading configurations on daylighting performance and to select the optimal solution. A louver system was parameterized according to a predefined process that associates its depth, count and rotation angle while a vertical screen was parametrized according to its scale and tilt angle. To examine the potentials of the proposed multi-stage method, it has been implemented on an office building located in new Cairo, Egypt. The results demonstrate that using the proposed optimization strategy drastically enhanced the Spatial Daylighting Autonomy of the building from 27% to 87% in comparison with the base case. Moreover, the optimum shading solution enhanced the daylighting quality by reducing the glare probability for better visual comfort from 60% to only 14%.

title	Immersive VR Environment for Construction Detailing Education: BIM Approach
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. 114-128
summary	According to literature in education, adults learn best when learning is active, self-directed, problem-based, and relevant to their needs. In Building Construction Education, construction site visits provide students with real-life practical experience which are considered an extension for classroom. Nevertheless, it is challenging to integrate construction site visits regularly during the academic semester with respect to the class specific needs. Virtual Reality as an interactive immersive technology may facilitate virtual construction site that meets the learning needs where students can explore and build in a real scale environment. The proposed VR environment is an HMD VR platform for construction detailing that provides experiential learning in a zero-risk environment. It builds on integrating VR technology as a medium and Building Information Modeling (BIM) as a repository of information. This work discusses the proposed environment curricular unit prototype design, implementation, and validation. System usability and immersion are assessed both qualitatively and quantitatively. After considering the feedback, The VR environment prototype is then validated on the level of learning outcomes, providing the evidence that it would enhance students’ engagement, motivation and achievement accordingly.
