title	Categorization of building product models in BIM Content Library portals
source	SiGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay- Montevideo 12,13,14 November 2014, pp. 370-374
summary	BIM Content Libraries are performing as online sources for building product models. In order to effectively use the product models, it is important to organize them systematically within these databases. But currently there is no standard or guideline for this purpose. Products in these libraries are being categorized based on different criteria such as the object classes in the target platform, by referring to multiple classification systems or based on customized categories. This paper studies some of the BIM Content Libraries and investigates the structure that each library is using for product categorization. It indicates the need for a generic framework for the purpose of product categorization in BIM Content Libraries.

summary	Education and Research in Computer Aided Architectural Design in Europe faces many urgent tasks. Among the Architecture, Engineering and Construction (AEC)international scientific societies, only few researches systematically investigate on how to integrate the design solutions with Health and Safety (HS) planning measures, enhancing a collaborative “fusion” of all involved actors in Design and Construction decision making. Process automation cannot be enhanced until design/management tools, such as Building Information Models, can rely only on entities formalised "per se" geometrical items fulfilled by isolated-object specific information. To face complex problems, BIM models should be able to implement and manipulate multiple sets of entities, qualified by clearly established relationships, belonging to organically structured and oriented (sub-) systems. This paper reports on an early stage research project, focused on the identification of operative rules for Health and Safety design. Implementation on the unique case study of Palazzo della Civiltà Italiana functional refurbishment faces two main objectives: one, more pragmatic, is concerned with boostingworkers education about non-standard operative tasks, by means of accurate ad-hoc construction narrative visualisation; another one, more challenging and theoretically complex, consists in modelling "judgment-based" rules, aimed at supporting automated reasoning in Safety Design.

summary	This article relates an experiment linking two types of forms: geometric forms generated from algorithms by mathematical functions and sonic forms generated from algorithms and linked to the first. In order to formalize a graphical and musical object called “sonic object" were used the following tools: the environment of a graphic program, the C# language and the Midi-dot-Net musical library. Diverse equations are used to generate the geometric shapes which generate periodical, cyclical and circular movements. Other equations used in the experiment are formulas adapted from the Edward Lorenz's Strange Attractor. Current research into the problem of the generation of patterns of movement, such as that of Jules Moloney, and research which deals with algorithms which generate shapes, such as that of Robert Krawczyk, have been taken as references and parameters for comparison for this work..

summary	This proposal is a continuation of a body of work we call ‘objects wrapped in objects’, which deals with discrete, chunky objects gathered and squished together in a sack. This strategy creates complex interstitial spaces and layered interiority, making the contemporary museum a space of surprises and discrete experiences rather than an endless continuum of paths. Tristan Garcia, the object-oriented philosopher, talks about the infinite regress of things inside of things inside of things, except the world, which everything is inside of and therefore cannot itself be inside of something else. For him, the concept of a ‘sack’, literally, is a diagram of the conundrum of how things can simultaneously be autonomous from one another but also contain other things. This conundrum is the core of our proposal, in that the building should appear simultaneously as multiple autonomous objects but also as a larger, emergent object with its own properties. The vibration between these two ways of existing creates a visual indeterminacy that is alluring and durable.On the south side facing the Park, the sack is sliced open to reveal an incongruent inner world of stepped and stacked public space. This space is formed by way of an inner liner, which delaminates from the sack surface. Permanent gallery spaces are housed in the space between liner and sack. The building is re-enclosed with a glass membrane which is not coincident with the sack silhouette, creating an open-endedness or deferral of interiority in the project. Black jack-like objects house various other functions such as the temporary galleries, theaters, research area, library, and offices. The interstitial spaces between objects and sack are technically exterior space, but they are enclosed with infill glazing deep inside reveals. These spaces are inhabitable and contain the primary circulation of the building.The sack is articulated with architectural tattoos that subvert subdivision logics in favor of the freeform figuration allowed by composite construction. Tattoos are executed in such a way as to blur the edge between discrete objects and visually re-establish the larger object, as if qualities from the black objects begin to loosen and drift onto the sack. Finally, the building is squished into a ‘ground object’ which is in turn squished into the land. The looseness between building and ground object allows for passage underneath the building. The looseness between ground object and land emphasizes the object-hood of the building complex. This move contrasts with exhausted ideas of buildings becoming landscape or otherwise disappearing into context

summary	By enabling BIM technology, a building can be represented by a set of objects that carry detailed information about how they are constructed and also capture the relationship with other objects in the building model. Smart BIM objects can be classified as specific com- ponents encapsulating typical building rules and relations that can be predicted and defined by a few parameters and constraints. A frame- work is developed to show how a smart BIM object is developed. This paper presents the method of developing smart BIM object capable of better-informing design decision. To demonstrate the usefulness of smart BIM objects, a cloud BIM object library is developed and tested by academia and industry.

title	A Review of Object Oriented CAD Potential for Building Information Modeling and Life Cycle Management
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	In many countries, the Architecture/Engineering/Consulting (AEC) industry is characterised by poor performance reflected in project delays and cost overruns. A contributor to the problem is the traditional approach to handling building information and its communication in life cycle management (LCM). Recent developments in Object Oriented Computer Aided Architectural Design (OO CAD) have provided the opportunity for improving building information modelling and its communication for more effective LCM. The aim of the paper is to review the potentials of OO CAD for building information modelling (BIM) and LCM. The paper reviews building information in the life cycle process, identifying the various actors and activities and the need for communication and information flow to support life cycle management. The paper also reviews the concept of OO CAD, highlighting its potential to improve building information and its flow and communication in life cycle management. The paper then goes on to review the potentials and limitations of OO CAD implementation in the AEC industry. The paper concludes by pointing out that the widespread adoption of OO CAD and the anticipated associated improvement in life cycle management will only be encouraged when the building industry is able to agree on a widely acceptable, interoperable standard for encoding building objects.

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.

title	Gusto: Rationalizing Computational Masonry Design

summary	Gusto 501 is a multi-level Infill Building on the footprint of an old car garage. Surrounded by an overpass and former factories, the restaurant and event spaces take the form of a ‘Hyper garage’ as a nod to its urban context. The interior is punctuated with standard terracotta blocks formed to create an intricate play of shadows during the day and embedded with LEDs to provide atmospheric illumination at night. The client's vision, our narrative, and the program demanded an innovative use of the primal material: terracotta. The scale of the project required the use of 3,700 blocks. Within the array wrapped around a 50ft tall interior volume, each block needed to be formed and sequenced uniquely to maintain structural integrity and interface with building systems, and express the sculptural qualities our team had designed. Standard approaches to the masonry could not achieve the effects our team was striving for - we had to develop our ground-up process to manufacture and install mass-customized masonry. The design process involved an algorithmic approach to a series of cuts and geometric manipulations to the blocks that allowed for near-endless combinations/configurations to create a dynamic interior facade system. Partisans, partnering with a terracotta block manufacturer, a local mason, and a masonry engineer, pursued simplifying production using wire cutter systems. Digital and physical mock-ups were then used to create a robust library of parameterized design criteria that optimized corbelling, grout thickness, weight, and fabrication complexity. Working sets of drawings were automated through a fully integrated BIM model, simplifying and speeding up installation. The challenge of marrying these processes with the physical realities of installation required another level of collaboration that included the masons themselves and the electricians who would eventually combine lighting systems into the sculpted block array.

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	This paper describes the current stage of an ongoing research developed at Mackenzie Presbyterian University, with support of FINEP, to use information and communication technologies (ICT) for the production of affordable houses in Brazil, focusing on the government’s program “Minha Casa Minha Vida” (My Home My Life – MCMV). Here we highlight the specific issue of adapting and extending the current BIM library of components provided by the Ministry of Development, Industry and Trade (MDIC), since the validity of the standard NBR 15575/13, which as of 2013, will guide the production of buildings in Brazil through strict performance requirements. We make a brief summary of the MCMV program, the terms of the standard and the structure of that library and then present guidelines for adapting and extending the existing components, taking into account international examples and the requirements from the new standard. As a result, we expect the revised components will facilitate the work of professionals in the building industry when designing and planning buildings.

title	An Urban Information Framework to support Planning, Decision-Making & Urban Design
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 653-668.
summary	This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

summary	Analyzing the success rate of the building process, it emerges that it is an industrial sector that lacks efficiency. Nevertheless, during decades the trend was to compare and bring into contact manufacturing management procedures vis-?-vis the building industry. But, whilst a manufacturing product is essentially a standard object produced in a controlled environment, a building is a prototype in itself. To bridge this gap research on Artificial Intelligence was conducted, so as to move from the traditional trial-and-error process to the simulation approach, defining in a virtual environment results of design and management choices before the real application, thus mitigating risks. To attain these results, a prototype was developed based on the Hybrid Actor Agent approach. The Agents, governed by their rules, behaviors and goals, define actions while Actors manage communication among them. The Network intertwined among these Agent/Actor systems is capable of stratifying knowledge based on the success rate of the choices made. The result of these concurrent computations is an optimized building process flow-chart

summary	For efficient interoperability of information between IFC (a standard open BIM model) and CityGML(a standard model in GIS), the information system is comparatively analysed through IFC, CityGML and LandXML. A direction for developing object-oriented AUIM (Archi-Urban Integration Model) for analysis and maintenance of spatial information is proposed. In this study, LOD for AUIM-based interior spatial information is presented. At the same time, strategies for BIM-GIS convergence are sought.

summary	MOLIT authorised Indoor Spatial Information as Basic spa- tial information in 2013. It became a legal evidence for constructing and managing Indoor Spatial Information. Although it has a little ad- vantage to utilise as service level that Indoor Spatial Information by laser scan or measurement, it has a lot of problems such as consuming many resources, requiring additional progresses for inputting Object Information. In conclusion, it is inefficient to utilise for the mainte- nance and domestic AEC/FM field. The purposes of this study is to output Indoor Spatial Information by operating IFC model which based on open BIM and to improve availability of Indoor Spatial In- formation with data visualisation. The open-sources of IFC Exporter, an inner program of Revit, is used to output Indoor Spatial Infor- mation. Directs 3D Library is also operated to visualise Indoor Spatial Information. It is possible to inter-operate between XML format and the objects of Indoor Spatial Information. It can be utilised in various field as well. For example COBie linkage in facility management, construction of geo-database using air-photogrammetry of UA V , the simulation of large-scale military operations and the simulation of large-scale evacuation. The method that is purposed in this study has outstanding advantages such as conformance with national spatial in- formation policy, high level of interoperability as indoor spatial in- formation objects based on IFC, convenience of editing information, light level of data and simplifying progress of producing information.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

summary	In this paper we present an outline of a newly started project to develop a tool which connects BIM to a manufacturing technique like 3D printing. First we will look some promising manufacturing techniques. We will design a small dwelling and export it into a BIM, from which we will extract our data to generate the path the nozzle has to follow. The chosen path is constrained by the material properties, the design and speed of the nozzle. To validate the system we develop a small VR tool in which we mimic a manufacturing tool.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

summary	Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary	The method proposed in this paper addresses the management of values and the cost estimate, based on target costing approach, and integrated with Building Information Model (BIM). This design method must incorporate mechanisms of automated assessment associated with desired value at cost during the design process. The paper will try to show, in brief, that there is a real possibility of inclusion of methodological tools of design, allowing assessment of values in real time during the design actions.
