title	Liability in BIM projects—Preliminary review results
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 476–490
summary	Building Information Modelling (BIM) fosters a collaborative working environment. With the industry moving toward this change, most practitioners believe that, compared to traditional methods, there will be a change in project liabilities and risk assignment. Design integration through BIM leads to ambiguity in determining the party responsible for the design. Therefore, BIM parties need to understand not only BIM but also the change in their responsibilities and think of solutions to liability and risk assignment. Based on the information gathered from three resources, this study aims at reviewing solutions to design liability assignment. These three resources are as follows: the existing research studies in the field of BIM adoption challenges, the existing contractual standards such as AIA G202, and contract conditions of 10 BIM projects. Findings indicate that there has been a lack of attention to design liability in BIM. The results provide significant insights into the status of BIM liability issue, the existing gaps in the knowledge, and potential future research

title	Parametric point-cloud slicing for facade retrofitting
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 434–452
summary	This work presents a method for retrieving 3D building contours usable in facade retrofitting projects, which uses a parametric modeling workflow that utilizes a point-cloud slicing method to retrieve such 3D contours. Since current commitments by European governments seek to reduce energy consumption as a means to reduce carbon emissions from building stock by 2050, facade retrofitting appears as an alternative for addressing operational and embedded building emissions. Within such a context, the main contribution of this work consists of a workflow and a 3D reconstruction solution that uses a parametric environment for capturing building topology and bypassing ground-level occlusions. A real case study and a strategy for converting 3D building contours into Industry Foundation Classes entities, directly from the parametric modeling environment, served as a scenario for testing the capabilities of a Grasshopper solution and open new perspectives for this approach.

title	Implementation of Point Cloud and BIM Technologies in a Construction Workflow: A Case Study of a Building Project in Yuecheng District, China
doi	https://doi.org/10.52842/conf.caadria.2022.2.567

summary	In recent years, there has been a surge of retrofitting and building projects in rural China, to elevate the living standards in local areas. However, with the conventional use of surveying and inspection instruments, the amount of construction errors account to substantial waste of materials, time and labour. The issue is magnified in the current context that emphasises on efficient utilisation of resources. The emergence of laser scanning and BIM technologies is evident with scanning equipment and software being more accessible. This paper explores the use of the two technologies, to be integrated into the a construction workflow. The research includes a self-conducted site survey, data collection, data processing and analyses. The processed point cloud data is extracted and compared to the as-designed BIM model, to analyse and assess the construction errors in various scales. The result displays a significant portion of the building being out of tolerance and its causes. A theoretical framework is proposed to integrate point cloud and BIM technologies, not only to document and assess the overall building dimensional accuracy, but also to minimise construction errors and waste, ensuring a responsible consumption and production of building materials.

summary	This research explores implementing computation to enhance access to ocean pool and marine landscapes for the inclusion of people who are blind or have low vision (BLV). Constructing reliable representations, explanations and descriptions can support interactions with objects and participation in activities, particularly in these ocean environments. We discuss the adoption of a series of computational design strategies to leverage the impact of recent scanning technologies in information transfer. The paper introduces a background to touch access and universal design. It presents a case study of aerial photogrammetry for an ocean pool in NSW, Australia, and presents multi-scalar workflows and processes across computational design and advanced fabrication methods, including a) photogrammetry through drone-flight on a macro-scale and 3D-scanning to establish data-sets; b) parametric design and scale adaptations;†and c) 3D printing and robotic milling for touch access.

title	Augmented Bricklayer: an augmented human-robot collaboration method for the robotic assembly of masonry structures
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 713–724
summary	The Augmented Bricklayer research project proposes a new augmented human-robot collaboration method for the robotic assembly of masonry structures. It aims to resolve the conventional limitations of the robotic bricklaying process by incorporating object recognition and Augmented Reality (AR) technologies. Towards this aim, we present a human-robot collaboration method consisting of two phases: a) the object recognition phase, in which bricks are recognized by a point cloud scanning sensor and analyzed by our calibration system as a feeding object for the robotic gripper to pick; b) the augmented human-robot collaboration phase, in which the masonry adhesive is being applied manually assisted by AR holographic guidance and gets assembled by an AR-assisted robotic operation method. The validation of our method is achieved with the robotic assembly of two real-scale building elements, a masonry column and a wall. Our findings highlight a more flexible, efficient, and convenient AR-assisted human-robot collaboration bricklaying method capable of dealing with complex on-site construction requirements.

title	Smart Hand for Digital Twin Timber Work -The interactive procedural scanning by industrial arm robot
doi	https://doi.org/10.52842/conf.caadria.2022.2.131
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 131-140
summary	This paper describes a 3D automated scanning method for building materials, namely "The Interactive Procedural Scanning‚, in a collaborative environment composed of a human worker and a CNC robot. This procedure aims to translate the observation skill of an experienced carpenter into an intelligent robotic system. The system frames its function on the first stage of a traditional timber examination process, called ‚Kidori‚, in which observations and findings are marked on the timber surface to provide hints for the subsequent cutting process. This paper aims to recreate the procedures using an industrial robotic arm, computer vision, and a human worker. A digital twin model of the timber is created with a depth camera serving as a base map to exchange information and receive instruction from the human worker. The margin of a discrepancy between the original processing location and the location of the actual end effector, where the tools are, is minimised in this system.

title	Digital Construction of Bamboo Architecture Based on Multi-Technology Cooperation: Constructing a New Parameterized Digital Construction Workflow of Bamboo Architecture From Traditional Bamboo Construction Technology
doi	https://doi.org/10.52842/conf.caadria.2022.2.223
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 223-232
summary	Limited by the non-standard nature of bamboo, bamboo has always been regarded as a traditional, restrictive, and time-consuming building material. Therefore, there is an urgent need for an enhanced parametric design system and digital construction workflow to upgrade the traditional bamboo construction process. In this paper, through the analysis of the bamboo pavilion "Diecui†Gallery" under the traditional construction method, five main factors restricting the development of bamboo architecture are obtained: difficult positioning of supporting structure, low efficiency of material selection and matching, the manual processing of materials, non-standard node and low utilization rate of non-standard waste materials. Then, through literature review, we proposed the technical means to improve these factors and put forward a multi-technology collaborative digital construction workflow. The workflow will comprise augmented reality, 3D scanning, robot-aided construction, 3D printing, and design rules. Moreover, by building parametric benches, we used augmented reality technology and new design rules to verify multi-technology collaborative fabrication workflow possibilities and effectiveness. This paper wants to explore a parametric design method based on bamboo material characteristics and multi-technology collaborative workflow, to improve the utilization rate of non-standard bamboo components in parametric design.

summary	Due to their recent popularity and success in fields such as engineering and business, gamification and by extension game design principles demonstrate the ability to teach complex, multi-disciplinary skills in an engaging, entertaining, and effective way. Architectural education especially introductory architectural education is a foundational and fundamental part of a budding architecture student’s career and oftentimes requires the understanding of dynamic systems, spatial reasoning, and experiential learning. The paper posits that gamification and game design principles can utilize certain components such as augmented reality, narrative design, and fun in order to create tools, gamify existing curriculum, and increase retention, engagement, and mastery of the difficult high-tech skillsets required of introductory architects. The paper focuses on reviewing and systematically analyzing research on gamification in education. In particular, it focuses on systematically reviewing and analyzing data from multiple relevant case studies chosen based on the application of technology such as augmented reality, the integration of game design, and the feasibility of gamification in educational environments. This data is examined based on feasibility, accessibility, and effects on information retention and the findings are outlined in a comparative table of methods, tools, and technologies organized based on their suitability. Ultimately, the paper aims to establish a framework for gamifying introductory modules in architectural education and hopes to create a future architectural augmented reality game meant to utilize gamification to help new architectural students.

summary	This study explores mass customization as an alternative strategy for social housing provision. The paper aims to demonstrate the implementation of an integrated system based on the connection between Building Information Modeling and algorithmic-parametric modeling technologies, seeking to design variability with real-time cost and time data control of single-family housing units. We developed the study according to five phases: (1) context analysis and design language definition; (2) rule-based design system definition; (3) cost and execution time estimation; (4) computer system based on the specified technologies definition; (5) quantitative evaluation and qualitative evaluation of the system. The experiment demonstrates that with the aid of algorithmic-parametric modeling, building information manipulation and visualization can be responsive enough to meet mass demands.

summary	This article aims to assess the degree of maturity of Building Information Modeling (BIM) in an Architecture and Urbanism course, identifying points of improvement and benefits, directing actions for a potential BIM implementation. The evaluation methodology investigates about Policies, Processes and Technologies of the architectural graduation course. The collection of information was done through questionnaires applied to the teaching staff. As results, it shows that BIM maturity,s level of the Institution in this course is in the ‘Defined’ level, however there are heterogeneous performances in relation to the evaluated points. It is also noticed that this result is due to the actions of a minority of teachers, not reflecting the institutionalized maturity of the entire course. On the other hand, this result indicates that efforts towards BIM adoption will start from initiatives already underway, in an environment relatively prepared for a planned insertion.

title	Towards Informed Design Decision Support of Additive Manufacturing in Construction: The Use of Integrated Knowledge in BIM-based Architectural Design
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 237-252
summary	Additive Manufacturing (AM) technologies have great potential to promote sustainable development in the architecture, engineering, and construction (AEC) domain. But the inherent complexity of AM and lack of domain knowledge hinder decisions about appropriate construction methods. With state-of-the-art Semantic Web technologies, a knowledge base regarding AM technologies can be formalized and integrated into the Building Information Modeling (BIM) methodology. To this end, this paper demonstrates how a Design Decision Support System (DDSS) utilizes formal knowledge to assist architects in choosing the appropriate AM method by assessing the manufacturability of individual building components. By following and refining the essential activities described, we aim to provide architects with informed decision support, thus facilitating the versatile use of AM technologies in the AEC domain.

summary	Geometrically complex building components‚ reliance on high-touch implementation often results in tedious information reprocessing. Recent use of Mixed Reality (MR) in architectural practices, however, can reduce data translation and potentially increase design-to-build efficiency. This paper uses Aurora, a single-story residential building for 2021 China‚s Solar Decathlon Competition, as a demonstrator to evaluate the performance of on-site holographic building construction. This paper firstly reviews recent studies of MR in architectural design and practice. It then describes an MR-aided construction process of Aurora's non-standard building envelope and rooftop mounting structure, where in-situ holographic registration, human-machine cooperation, and as-built analysis are discussed. This paper concludes by stating that MR technologies provide unskilled implementers with a handy approach to materialise complex designs. The research was guided by the UN Sustainable Development Goals, especially aligning with the GOAL 9 which seeks innovations in industry and infrastructure.

summary	We present a synergetic combination of two previously separate process technologies to create novel lightweight structures. 3D textiles and 3D printing. We will outline the development of a novel material system that consisted of flexible and foldable 3D textiles that are combined with stiff, linear 3D printed materials. Our aim is to produce material-reduced lightweight elements for building applications with an extended functionality and recyclability. Within an ongoing research project (6dTEX), we explore a mono-material system, which uses the same base materials for both the filament for 3D printing and the yarn of the fabrication of the 3D textiles. Based on preliminary 3D printing tests on flat textiles key process parameters were identified. Expertise has been established for 3D printing on textiles as well as for using printable recycled polyester materials (PES textile and PETG filament. Lastly for 3D printing on non-combustible material (alkali-resistant (AR) glass textiles and for 3D concrete printing (3DCP). The described process- knowledge facilitates textile architectures with an extended vocabulary, ranging from flat to single curved and folded topologies. Whereas the foundations are laid in the research project on a meso scale, we also extended our explorations into an architectural macro scale. For this, we used a more speculative design-build studio that was based on a more loose combination of 3D textiles and 3D printed elements. Lastly, we will discuss, how this first architectural application beneficially informed the research project.

title	Framework of an algorithm-aided BIM approach for modular residential building information models
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 4, pp. 777–800
summary	The digital transformation of the construction industry and the lack of integration of digital technologies in design and construction processes are the motivation for this research. BIM solutions enable new levels of design processes and provide platforms for computational design and novel approaches in the AEC industry. In computational design parametric, generative or algorithmic procedures are utilized to support, optimize, or replace manual processes. The combination of BIM and generative, parametric or algorithmic design forms a hybrid that aims to combine the advantages of both concepts and allows for generative design processes with the creation of BIM objects containing metadata. Along with the digital transformation and novel approaches in the AEC industry, modular construction aims to shift from mass production to mass customization and maximize opportunities for cost-effective, economical, and sustainable buildings. This paper addresses the approach of generating building information models using algorithm-aided design combined with BIM at an early design stage for modular multi-story residential buildings that are affordable and sustainable. In this study, we present the framework of an algorithm-aided BIM approach, from the concept of the generative algorithm to the evaluation approach and the proof of concept as the test of the framework

summary	Over time, digital fabrication technologies were assimilated, based on project references, techniques and machinery from the global north, determining dependency relationships. Recently, architecture and design schools, fab labs, and design offices in South America have expanded their infrastructure in order to create laboratories using these technologies. The objective is to present framings about production plus a framework for the application of technologies. Originated from a thesis research, the methods that support the theoretical elaboration consisted of a bibliographic and systematic review of topics related to digital fabrication, information mapping, surveys, interviews and case studies carried out in South America. The contribution of the article is to provide a background for thinking, interpreting and executing procedures and artifacts with the support of digital fabrication, oriented to the development of our context. In addition, it deepens a critical view of this condition, which involves advances in socio-technical adequacy and innovation policies.

title	The Reproduction of Chinese Traditional Timber Structure
source	ACADIA 2022: Hybrids and Haecceities [Proceedings of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 598-603.
summary	In Chinese traditional timber building, “Dou-gong” stands as one of the most distinctive features to present the Chinese structure style. However, the preservation and reproduction of Dou-gong face difficulties due to the withering craftsman issue. This paper proposes a method to digitize the structure into BIM (building information modeling) and reproduce it via robot-based fabrication. By modeling these Dou-gong components with BIM technologies, we can establish a geometrical and non-geometrical 3D database. Then we use Autodesk Fusion and Grasshopper to design the robotic fabrication information whose information is transferred from 3D database models. Based on the fabrication information, including work paths and tool parameters, the KUKA robotic arm with six axes can precisely mill the wood materials into Dou-gong components without any traditional craftsman’s processing.

summary	The use of BIM combined with Augmented Reality (AR) and Virtual Reality (VR) technologies allows the development of Virtual Design Construction (VDC). However, such application isn’t widespread in construction sites, which have their management and control performed in a traditional way. With this research, 05 applications were mapped that allow the use of BIM in conjunction with AR, listing the main uses of each application, and finally, an experiment was carried out on the use of AR on a construction site. The integration of BIM with RA makes it possible for the project manager to have the project information in loco. This context allows to collect and share construction information at the site during the building process.

summary	Building Information Modeling (BIM) is the current expression of innovation in the construction industry, a set of technologies, processes and policies that affect the deliveries, the relationships, and the roles of the civil construction industry. In Brazil, BIM is still scarce, especially in the public sector. Due to this problem, this study aims to elaborate a BIM Execution Plan for public works project contracts. The focus of this study is a public institution in the state of Ceará. For the development of this study, we adopted the Design Science Research method. As a result, we obtained a BIM Execution Plan that served as a foundation for the elaboration of BIM projects in the public institution in question. Therefore, this study contributes to the reduction of the main errors in BIM project contracting and, as a result, to the dissemination of BIM in the state of Ceará.

summary	Efficient management of solar radiation through architectural glazing is a key strategy for achieving a comfortable indoor environment with minimum energy consumption. Conventional glazing consisting of a single or multiple glass pane(s) exhibits high visible light transmittance and solar heat gain coefficient, which can be a double-edged sword, i.e., it allows sufficient sunlight to enter the building interior space for passive heating and lighting; on the other hand, it can cause glare discomfort and large cooling energy consumption. Among the various advanced glazing technologies being developed, Building Integrated Photovoltaic (BIPV) glazing has a prominent position due to its ability to reduce cooling load and visual discomfort while simultaneously generating electricity from sunlight. Recent years have witnessed remarkable advances in low-concentration optics such as Dielectric based Compound Parabolic Concentrators (DiCPCs), with a growing interest in the development of Building Integrated Concentrating Photovoltaic (BICPV) glazing to improve light harvesting and electric power output. One of the challenges faced by traditional BIPV glazing systems is the lack of dynamic control over daylight and solar heat transmission to cope with variations in weather conditions and seasonal heating/cooling demands of buildings. A promising solution is to integrate an optically switchable smart material into a BIPV glazing system, which enables dynamic daylighting control in addition to solar power conversion. Thermotropic (TT) hydrogel materials such as poly(N-isopropylacrylamide) (PNIPAm) and Hydroxypropyl Cellulose (HPC) are potential candidates for hybrid BIPV smart glazing applications, due to their unique features such as high visible transparency (in the clear state), strong light-scattering capability (in the translucent state) and large solar energy modulation. This paper reviews various types of electricity-generating glazing technologies including BIPV glazing and BICPV glazing, as well as smart glazing technologies with a particular focus on TT hydrogel integrated glazing. The characteristics, benefits and limitations of hybrid BIPV smart glazing are also evaluated. Finally, the challenges and research opportunities in this emerging field are discussed.
