Architecture, engineering, and construction industries maintain a long standing desire to enhance design communication through various forms of 3D CAD modeling. In spite the introduction of Building Information Modeling (BIM), designers and builders expect varying amounts of communication loss once construction has started due to indirect construction techniques or hand based methods to manufacture buildings. This is especially true for houses and small structures, buildings that makeup the core of villages and suburbs. Unfortunately, paper documentation and reading 3D CAD models on screen continue the trend of indirect production defined in most manufacturing industries as error. The emerging application of CAD/CAM within design and construction industries provides hope for elevated communication between design and building. With CAD/CAM, it is possible to manufacture buildings of all types and sizes directly from CAD files similar to mass produced artifacts, thus reducing complexity in communication between parties. This chapter is presentation of one process of direct manufacturing from CAD and the emerging possibilities for small building production using digital fabrication. The chapter will focus on houses to illustrate the potential of direct manufacturing of buildings from CAD data.

Lean Construction techniques have been introduced as an alternative way for conventional construction process in 1990’s.. It is described as a process of eliminating waste, increasing worth and value, and meeting or extraordinary client necessities and requirements. Waste reduction and customer value satisfaction are important factors to be considered in implementing construction projects. Building Information Modeling (BIM) is an intelligent model based process. BIM implementation seems to more advantageous in construction industry, for instance, it makes use of visualization technique of a product to facilitate architecture, engineering and construction professionals to effectively plan, design and manage infrastructure. Review of literature is administered and a survey is conducted to identify major issues involved in adopting Lean and BIM in construction sector. The present study depends mostly on the survey questionnaires from building professionals. Totally forty construction companies were selected for the questionnaire survey. The results obtained were analyzed in Statistical Package for Social Science (SPSS). The outcome of the study indicates that Lean and BIM implementation is necessary for allocation of resources, quality improvement and it enhances the sustainability of building and also it signifies that there is a shortage in lack of awareness, lack of framework and professionals.

Transfer Of Information

Construction knowledge can be communicated and reused among project managers and jobsite engineers to alleviate problems on a construction jobsite and reduce the time and cost of solving problems related to constructability. This paper proposes a new methodology for the sharing of construction knowledge by using Building Information Modeling (BIM) technology. The main characteristics of BIM include illustrating 3D CAD-based presentations and keeping information in a digital format and facilitation of easy updating and transfer of information in the BIM environment. Using the BIM technology, project managers and engineers can gain knowledge related to BIM and obtain feedback provided by jobsite engineers for future reference. This study addresses the application of knowledge sharing management using BIM technology and proposes a BIM-based Knowledge Sharing Management (BIMKSM) system for project managers and engineers. The BIMKSM system is then applied in a selected case study of a construction project in Taiwan to demonstrate the effectiveness of sharing knowledge in the BIM environment. The results demonstrate that the BIMKSM system can be used as a visual BIM-based knowledge sharing management platform by utilizing the BIM technology.

The paper analyses the procedure to create a 3D model of a neogothic family chapel situated in Castellón de la Plana (Spain). The characteristics of the case study make it an emblematic case of Building Information Modeling (BIM) applied to Cultural Heritage (Historic BIM). The paper explores the workflow used to create the model and how the difficulties encountered have been addressed. The key motivations for this research project are: (i) local authority needs and objectives (restoration works for the conservation of architecture; necessity to monitor the asset after restoration); (ii) the intrinsic peculiarities of the small building (vast diversity of materials, richness and diversity of decorative elements); (iii) the creation of a pilot project for future applications in similar architectures. The chosen workflow tries to tackle the principal issues shared by the academic world with respect to 3D and HBIM models, e.g. the difficulty in reconstructing complex architectures without time-consuming processes, the reliability and high detail in the rendering of colours and textures, the insertion of detailed information for each element. The experiments carried out have made this case study interesting because of its complexity despite its reduced dimensions.

Knowledge management (KM) is the organization, creation, sharing and flow of knowledge within organizations. Knowledge can be shared and reused among involved engineers and experts to improve a construction process and reduce the time and cost of solving problems. This paper proposes a new and practical methodology to capture and represent construction project knowledge by using a Building Information Modeling (BIM) approach. Using BIM approach, users can make visual knowledge management in the 3D Computer-aided Design (CAD) environment. This study addresses the application of knowledge management in the construction phase of construction projects and proposes a Construction BIM-based Knowledge Management (CBIMKM) system for general contractors. The CBIMKM is then applied in selected case studies of a construction building project in Taiwan to verify our proposed methodology and demonstrate the effectiveness of sharing knowledge in the 3D environment. By applying the BIM approach, all participants in a project can share and reuse explicit and tacit knowledge through the 3D CAD-based knowledge map. The combined results demonstrate that the CBIMKM system can be used as a visual 3D-based knowledge management platform by utilizing the BIM approach and web technology.

<p><strong>Abstract.</strong> The <i>Building Information Modeling</i> is today one of the most advanced data cataloging and processing systems aimed to the digital representation of physical and functional characteristics of an object. These prerogatives make possible to create a model containing not only the geometric-architectural data of the building, but also the properties of the materials and technical elements that compose it, the construction phases, as well as maintenance operations, locating and programming them over time. Such an approach implies, therefore, not only a change of instruments for the representation of Architecture, but above all a change of "mentality", in which the building is seen as a "unitary" organism with a synchronous vision between architectural form, structural elements, construction techniques, materials and installations. The experimentation here presented concerns the case of the university complex of Federico II of Naples along the axis of Via Mezzocannone. The urban palimpsest housing the monumental front of the building, designed by Eng. Pierpaolo Quaglia and Guglielmo Melisurgo at the end of the Nineteenth century, and incorporating ancient religious complexes built in the Fifteenth century, as the monasteries of Donnaromita and the Old Jesus; heterogeneous elements that allowed to explore on the field limits and the possibilities of interoperability of BIM in which still have ample possibilities for experimentation.</p>

<p><strong>Abstract.</strong> The developments of the latest technology in the field of Digital Cultural Heritage (DCH) are revolutionizing the methods of surveying, representing and managing the built heritage. The integrated use of 3D survey instruments such as laser scanning, digital photogrammetry and the new holistic way to represent the architecture, based on the Building Information Modeling (BIM), allows the collection, analysis and archiving of a large amount of data, by increasing information sharing among a great number of experts involved during the life cycle of the building. The paper focuses on the connection between Italy and Czech in terms of vaults patterns and construction techniques. The two case studies are the frame vault of the chapel of the Italian Cultural Institute and the barrel vault with lunettes of the Klementinum Baroque Library. They are both unique examples of the great expertise of architects and craftsmen that worked in Bohemia across the 17th and 18th centuries. Most of them were from the North of Italy, like the ones that worked in the building sites of the two case studies. The in-depth study of the construction techniques and the complex shapes needs the use of new scan-to-BIM modeling requirements, based on the definition of geometric primitives useful for the generation of intelligent three-dimensional models able to integrate different types of data. Finally, the acquired data are included in a database that collects information coming from both Italian and Czech studies, raising awareness among citizens of the richness of their built heritage.</p>

The Relationship

Harnessing, distributing, tempering and supplying water, heat and power in a building produces its share of design, technical and coordination issues. Specifically, the relationship between hygiene and cooking functions and architecture has been underscored by even the most ancient civilizations as these services give a building its potential to serve and showcase architecture’s hospitality. The relationship between services and architectural space has long challenged designers and manufacturers to streamline their piecing together. Throughout construction history and modern architecture in particular the wet service core or utility core sought to organize an efficient way of zoning services, their production and construction integration; The utility core epitomized this rationalization within a self-contained engine-like device positioned to serve the entire dwelling. This paper proposes an extensive review of literature and practical exploration in order to detect new potentials for designing integrated, technology-driven, flexible and adaptable prefabricated utility cores for today’s industry. The core was intended as a hub accommodating mechanical and technological equipment; electrical services, plumbing fixtures, water supply, drain, waste, vent piping, telephone cables, and easy connections to site infrastructure. Today’s techniques and building information modeling allows the core to be redefined in relation to multiple scales and various organizational possibilities with regard to space/function connections. Further an adaptable core articulated to the «open building» theoretical framework of layering systems to avoid entanglement and to maximize durability, can be part of a comprehensive strategy to enable customization. The vast amount of literature and precedents contribute to a robust historic narrative of two distinct approaches of architectural rhetoric and industrial production.  This paper will endeavor to illustrate this narrative and evaluate the potentials for achieving broader application.
