title	An Italian BIM-based portal to support collaborative design and construction - A case study on an enhanced use of information relying on a classification system and computational technical datasheets

summary	A great amount of information needs to be managed along the building life cycle in order to fulfil building codes, standards and regulations, client and user requirements. However, a lack of transparency in the information management and a lack of communication between stakeholders often bring to the adoption of solutions in the design process that do not meet the original requirements. Therefore, an ordered structure for information improves its storage, enhancing its visibility, traceability, usability and re-usability. In addition, for public works contracts and design contests, the use of specific electronic tools, such as building information electronic modelling tools, is often required for the information management. The paper presents the efforts devoted within the Italian building sector for proposing a standardized structure and developing tools for collecting, sharing and exchanging information between stakeholders involved in different stages of the building process. An enhanced use of information relying on the adoption of the standardized structure of information is presented, proposing dedicated applications for automating the process of information fruition.

summary	To construct a building that meets the requirements of certification in terms of environmental friendliness, there must be a process that considers the certification criteria from the initial design phase. However, there are numerous complicated task performance procedures to analyse many required items in detail as well as perceive and apply the data requirements efficiently. Currently, Building Information Modeling (BIM) is gaining attention as a solution for environmental problems in architecture. BIM shows precisely how a virtual building is modelled in the real world, thereby providing an objective information and analysis through a simulation. However, the result values of BIM library or modelling may turn out differently as a result of the work environment of designers or users that is not standardized. Therefore, this study applies the modelled and extracted BIM data using the template and library established in the BIM add-in planning and design phase to review in advance the Green Standard for Energy and Environmental Design (G-SEED) assessment by item and manual input of users with the BIM-based (add-in) G-SEED assessment system, thereby providing support to enable users to establish specific strategies in designing green buildings.

summary	Researchers attempt to offer new design tools and technologies to support design process facilitating alternative visualization and representation techniques. This paper describes a comparison study that took place in the Department of Architecture, at the Istanbul Technical University between 2016-2017. We compare when architects designed mass volumes of buildings in an marker-based mobile Augmented Reality (AR) application with that of when they used a collaborative 3D Virtual World. The massing strategy in the AR environment was an additive approach that is to collaboratively design the small parts to make the whole. Alignment and arrangement of the parts were not the main concerns of the designers in AR, instead the functional development of the design proposal, bodily engagements with the design representation, framing and re-framing of the given context and parameters become the discussion topics.

summary	The construction sector is responsible for a big share of the global energy, resource demand and greenhouse gas emissions. As such, buildings and their designers are key players for carbon mitigation actions. Current research in digital fabrication is beginning to reveal its potential to improve the sustainability of the construction sector. To evaluate the environmental performance of buildings, life cycle assessment (LCA) is commonly employed. Recent research developments have successfully linked LCA to CAD and BIM tools for a faster evaluation of environmental impacts. However, these are only partially applicable to digital fabrication, because of differences in the design process. In contrast to conventional construction, in digital fabrication the geometry is the consequence of the definition of functional, structural and fabrication parameters during design. Therefore, this paper presents an LCA-based method for design-integrated environmental assessment of digitally fabricated building elements. The method is divided into four levels of detail following the degree of available information during the design process. Finally, the method is applied to the case study "Mesh Mould", a digitally fabricated complex concrete wall that does not require any formwork. The results prove the applicability of the method and highlight the environmental benefits digital fabrication can provide.

summary	Algorithmic-based Building Information Modelling (A-BIM) allows the development of BIM models through algorithms. In a collaborative environment, A-BIM requires management strategies to deal with concurrent development of architectural projects. However, despite there being several tools that support this type of collaborative work, they are not appropriate for A-BIM because: (1) they track changes in the generated model instead of the code where the changes originate from, and (2) they are vendor-specific while A-BIM models might be generated for different BIM applications. In this paper, we discuss the use of Version Control (VC) for project management and concurrent development of A-BIM projects. We evaluate VC for A-BIM through a series of scenarios in the context of a case study.

summary	Traditional design paradigms take into account phases as the process were subdivided rigidly in boxes to which pertain specific building entities, actors and LODs. In reality the process of design, a building f.i., it is not so much organized in series, nor designers deal with just a specific LOD. The process is intertwined and actors mix various type entities with different accuracy. To manage these problems, we need a new paradigm and new tools able to take immediately into account satisfied/unsatisfied constraints, to trig on consequences of choices made as far as it is possible and to link fluently and bidirectionally a 2nd layer of building abstraction (BIM) with a 3rd one of knowledge abstraction. An on-the-fly link has been established between BIM and a swarm of agent-based simulations.

title	A Comprehensive Application of BIM Modelling for Semi-underground Public Architecture: A Study for Tiantian Square Complex, Wuhan, China

summary	The paper presents research on how Building Information Modelling (BIM) can be applied comprehensively throughout the design of an architectural project. A practical method based on BIM models that help to deal with multidisciplinary issues by integrating the design information from different sources, collaborators and project stages is formulated by adopting existing available tools. The ‘Tiantian Square’ building project in Wuhan, China combines a subway station with a commercial hug. According to the project’s size and complexity, our study focuses on the multiple cooperation of professionals from different backgrounds, including the departments of architectural design, structure (civil engineering), HVAC (Heating, Ventilation and Air Conditioning), water supply and drainage, and electrics and sustainable design. Our paper presents how the BIM model bridges between various simulation platforms through our technical system and management, including steps of transformation, simplification, analysis, reaction and improvement. Our research has helped to improve the overall efficiency and quality of the project. We generated a successful analysis-design approach for the initial design stages, which does not require in-depth analysis. It is a practical method to immediately evaluate the performance for each design alternative and provide guidelines for design modification. Finally, we discuss how the coordination of different department becomes a crucial factor as we look forward to a more open, communicative and inter-relational design and development process.

title	Rule-based Security Planning System for Practical Application

summary	Security planning is a vital part of the operation and management phase in a building’s life cycle. Ideally, this will be addressed during the building design phase. However, reality often differs from this ideal. In the real world, information such as floor plans tend to insufficiently describe or imperfectly match physical buildings, and must be surveyed and re-worked during security planning. Because of this, security companies require two kinds of staff: those in the security business and those in charge of planning, including floor plan verification. This research focused on creating an efficient way to help staff in this work environment develop a system of security planning for buildings and facilities using a rule-based approach in a tailormade CAD system. In this research, we developed a new 3D CAD system for desktops and mobile devices, which specializes in security planning using a game-engine. To avoid errors during security planning, a rule-based check system was developed and integrated into the CAD system. The rule-set of this rule base was built from the security planning manual, including guidelines on equipment layout and wiring in various situations, which could then be used in the development of an automated check. This research describes the method of system development and final results.

title	Algorithmic-Based Analysis - Design and Analysis in a Multi Back-end Generative Tool

summary	Estimating a building's performance is part of the engineering and architecture discipline. Nowadays, this estimation is done using analysis tools. In many cases, these analysis tools require specialized building models that are simplifications of the actual models. Unfortunately, the adaptations that need to be done to an existing model are tiresome and make the architect less willing to evaluate variations of the building design. Moreover, in the case of buildings with complex shapes, the analyses tend to be less reliable. These problems also occur when algorithmic approaches are used to generate the building design, as the algorithmic script needs to be adapted to satisfy the requirements of the analysis tool, or the manual adaptation of the generated model needs to be repeated each time the script is executed. To solve these issues we propose Algorithmic-Based Analysis. This is a Generative Design method that, utilizing a single algorithmic-based representation of a building, can generate not only the traditional CAD or BIM model, but also specialized models for use in different kinds of analysis.

summary	Recently, the aging of buildings is accelerating around the world. In line with this, architectural structures constructed long time ago require life extension and ongoing management and protection for improvement, because they are too deteriorated. In particular, since structural safety inspection and analysis in building is very important, 'DFS (Design For Safety)'system has been introduced and conducted at the national level in Korea for the whole building life cycle management system encompassing the entire design, work commencement, construction, and completion stages. However, we do not have a system ranging from repair and reinforcement work plans in doing safety design, structural inspection and analysis to ongoing safety inspection. Therefore, it is necessary to establish a system to produce and share integrated information and conduct a research to manage architectural structure across the whole life cycle. Accordingly, this study aims to propose BIM-based reverse engineering technology for generating a safety management model based on laser scanner, verify the investigation items to be utilized of the design when building safety, and seek ways to utilize them for safety design.

title	Resilience Design
source	SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017
summary	The chosen theme, Resilience Design, evidences the researchers’ concern about issues related to our reality of climate change and natural disasters, associated with the states of vulnerability and risk, having wide effects on society and the way we inhabit territories. These matters are fundamental and highly relevant for the disciplines and in the fields of design and architecture, as they are also important for collaborative work with areas emerging from the arts and human sciences. Thinking about Resilience Design is to set ourselves on new scenarios of reflection and action which, supported by transdisciplinary thinking and collaborative design, allow us to develop a new approach towards our territories and their demands, one that is more contextualized and adjusted to their current and future requirements, a starting point to establish the key elements to drive change in our cities and society. In this sense, technology and digital development, parametric design, the use of Information and Communication Technologies (ICT) and Geographic Information Systems (GIS), in addition to work done with Building Information Modelling (BIM), among many others, have been delivering an enormous amount of tools and possibilities of interaction with living in society, leading to a substantive change in the way of understanding and relating to the built environment and the territories where buildings are sit. This demands a strong commitment to Social Responsibility from our disciplines, besides the necessary landing of cutting-edge technological and digital research and development onto our diverse realities, in order for them to be put at the service of communities in vulnerable environments or with a marked condition of risk, which are subject to constant processes of resilience. Working on Resilience Design allows to support research and productive processes, plus the appearance of new technologies in interdisciplinary contexts, which greatest value is to impact the processes of teaching and professional practice in the different areas related to human habitation. The new professionals will have to take action and immerse themselves into these new scenarios of change and constant adjustment.

summary	This research investigates the development of a new modelling and simulation approach for building design - defined as Agent-Based Building Modelling - that moves from the current object-oriented representation (such as in BIM) to an agent-based one. In the proposed approach, the representation domain is extended in order to include users and hosted activities, and the static modelling of the building is integrated with the dynamic simulation of its functioning. For this purpose, this paper presents a general template of the agent that ensures homogeneity of formalisation of the different typologies of entities (building components, spaces, V-Users, activities) and support the virtual simulation of the use process.

summary	This paper studies the process of conception in BIM architecture, using concepts of Peircian semiotics, in order to apply it in the design oriented to the resilience. There are three ways of designing in Revit Architecture software: (i) the conceptual mass, which demonstrates an abductive-iconic type of reasoning and a stereotomic process. (ii) Object-based modeling, which demonstrates a deductive/inductive-symbolic and a tectonic procedure and (iii) collaborative modeling, which manages to initiate a parallel process between different professionals and the community. These processes are understood in a semiotic relationship, in which are present signs and reasoning of different hierarchies.

summary	We present initial experiments of Web-based Parametric Building Information Modeling (WP-BIM) towards collaborative design, modeling, simulation, and optimization. A new framework that integrates Web-based information technology (WebGL graphics, networking, and Web browsers), and design computing technology (visual programming) into parametric BIM is prototyped for the experiments. The integration of Web technology is going to enable online collaborative and user participatory design. Connected through the Web platform, a BIM model, visual programming-based user interfaces for parametric changes, and an optimization algorithm, which may reside in different servers or local computers in different geographical locations, have the potential to be integrated and working together to resolve design optimization problems, especially if combined with cloud-based performance simulation tools. After future development, this may allow architects, engineers, clients, etc. to collaboratively work on a project with up-to-date building data and different design and simulation tools.

doi	https://doi.org/10.52842/conf.acadia.2020.1.382
summary	We present a framework to generate intelligent spatial assemblies from sets of digitally encoded spatial parts designed by the architect with embedded principles of prefabrication, assembly awareness, and reconfigurability. The methodology includes a bespoke constraint-solving algorithm for autonomously assembling 3D geometries into larger spatial compositions for the built environment. A series of graph-based analysis methods are applied to each assembly to extract performance metrics related to architectural space-making goals, including structural stability, material density, spatial segmentation, connectivity, and spatial distribution. Together with the constraint-based assembly algorithm and analysis methods, we have integrated a novel application of deep reinforcement (RL) learning for training the models to improve at matching the multiperformance goals established by the user through self-play. RL is applied to improve the selection and sequencing of parts while considering local and global objectives. The user’s design intent is embedded through the design of partial units of 3D space with embedded fabrication principles and their relational constraints over how they connect to each other and the quantifiable goals to drive the distribution of effective features. The methodology has been developed over three years through three case study projects called ArchiGo (2017–2018), NoMAS (2018–2019), and IRSILA (2019-2020). Each demonstrates the potential for buildings with reconfigurable and adaptive life cycles.

title	Free-form Transformation Of Spatial Bar Structures - Developing a design framework for kinetic surfaces geometries by utilising parametric tools

doi	https://doi.org/10.52842/conf.ecaade.2017.1.747
summary	This paper presents a design framework for free-form transformation of kinetic, spatial bar structures using computational design techniques. Spatial bar structures considered as deployable, transformable kinetic structures composed of straight, linear members, assembled in a three-dimensional configuration. They are often utilised in portable, mobile or transformable buildings. Transformable systems of spatial bar structures are mostly based on modification of primitive shapes (e.g. box, sphere, and cylinder). Each system is subdivided into multiple members having the same shape, the so-called kinetic blocks. Some diverse precedents made to develop other forms of transformation of these structures with some issues. This research project will investigate how a free-form transformation of spatial bar systems can be achieved, by redesigning the kinetic block in relation to architectural, technical parameters. In order to develop a physical prototype of the kinetic block, and assess its potential in enabling free-form transformation of a spatial bar system, a design framework incorporating parametric, algorithmic and kinetic design strategies is required. The proposed design workflow consists of three main phases: form-finding, stability validation and actuation.

summary	Planning for resilience and enabling positive design outcomes requires combinatory methods of working with data, in order to assist decision-makers develop evidence-based methodologies and easily communicated scenarios. The staggering rise of technology integration and data-aided analysis tools in urban planning, not only facilitates our understanding of socio-economic flux, but attempts to actively involve users as a way of creating environments that are more responsive and appropriate to their needs. This paper aims to contribute to the discourse on user involvement in design-oriented fields, in our case, urban planning, by analyzing two different approaches of participatory design.

title	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects

summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

title	Lumifoil and Tschumi: Virtual projections and architectural interventions
source	International Journal of Architectural Computing vol. 15 - no. 1, 6-17
summary	This article introduces the theoretical and technical framework for the design of a temporary rooftop canopy on the red generator—one of the buildings designed by Bernard Tschumi for the Florida International University School of Architecture. The project, Lumifoil, was designed using both top-down and bottom-up computational techniques, including surface modeling via projected geometries and scripted cellular subdivisions and assemblies. Lumifoil attempts to synthesize these two often-conflicting design approaches into a generative design process which leverages context, form, surface, and structure as affective and effective actors. Lumifoil is the result of a design methodology which is both active and reactive to existing conditions of the site and new opportunities afforded by the program. It is contextual in its top-down relationship to Tschumi’s existing building and theory, generative in how details emerge bottom-up through scripts which lack any reference to site, and emergent in the resulting synthetic processes and effects which are produced. Through this methodological development, the project both tracks and responds to popular architectural theory and design from the mid-1990s to today. The theoretical underpinnings of the project build upon the idea that the actual (the real-life physical manifestation of matter) and the virtual (the potential for an object to be) are two constantly shifting paradigms in which design processes can intervene to help develop an architectural solution from a range of possibilities. The technical aspect of the project includes the collaborative workflow between the architecture offices of OTA+ and studio MODO with Arup Engineers to resolve structural issues using parametric modeling tools and structural analysis software. The final project is entirely parametric and fabrication is completely automated.
