Lean production revolution started in manufacturing with origin in the Toyota Production System (TPS). Since Womack, Jones, and Roos (1990) announced this concept as a new production paradigm, various industries including the Architecture, Engineering and Construction (AEC) Industry have paid attention to its possible applications. While design, engineering and building practices in AEC are substantially different from manufacturing, the ideas drawn from Lean Production can be tailored for the AEC environment. The synthesis of lean production principles and techniques applied in AEC form the basis for a Lean Project Delivery System™ (LPDS). The principles of LPDS and Building Information Modeling (BIM) technologies offer new approaches and opportunities to improve the quality, cost, schedule and productivity of building products in a highly fragmented multi-disciplinary sector. The case study presented in this chapter provides an overview of the synergy between the principles and tools of LPDS with BIM technologies used at the California Pacific Medical Center’s (CPMC) Cathedral Hill Hospital (CHH) project in San Francisco, California.

This study analyzed the impact of organizational factors on delays in building information modeling (BIM)- based coordination for mechanical, electrical, and plumbing (MEP) systems from the decision-making perspective. Recently BIM-based coordination has been regarded as a critical phase in project delivery but suffers from delays during the coordination process. This study investigated three complexity factors that often contribute to coordination delays: the number of participants – the total number of participants involved in a decision-making process for resolving a coordination issue; the level of the decision makers – the highest decision-maker involved in a problem-resolution process; and the heterogeneity of participants –the number of trades related to an issue. Using 95 major coordination issues derived from 11,808 clashes in a case study, the correlations between the coordination time and the complexity factors were analyzed. The coordination time linearly increased as each factor increased. The number of participants had the highest correlation with the coordination time, followed by the level of decision makers and the heterogeneity of participants. The findings stress the significance of integration between BIM and lean approaches, such as Obeya (big room) and Shojinka (flexible manpower line), during BIM-based coordination to expedite decision-making processes and eventually to reduce the coordination time.

Improving the energy performance of existing buildings is one of the main strategies defined by the European Union to reduce global energy costs. Amongst the actions to be carried out in buildings to achieve this objective is working with passive measures adapted to each type of climate. To assist designers in the process of finding appropriate solutions for each building and location, different tools have been developed and since the implementation of building information modeling (BIM), it has been possible to perform an analysis of a building’s life cycle from an energy perspective and other types of analysis such as a comfort analysis. In the case of Spain, the first BIM environment tool has been implemented that deals with the global analysis of a building’s behavior and serves as an alternative to previous methods characterized by their lack of both flexibility and information offered to designers. This paper evaluates and compares the official Spanish energy performance evaluation tool (Cypetherm) released in 2018 using a case study involving the installation of sunlight control devices as part of a building refurbishment. It is intended to determine how databases and simplifications affect the designer’s decision-making. Additionally, the yielded energy results are complemented by a comfort analysis to explore the impact of these improvements from a users’ wellbeing viewpoint. At the end of the process the yielded results still confirm that the simulation remains far from reality and that simulation tools can indeed influence the decision-making process.

Traditional energy analysis in Building Information Modeling (BIM) only accounts for the energy requirements of building operations during a portion of the occupancy phase of the building’s life cycle and as such is unable to quantify the true impact of buildings on the environment. Specifically, the typical energy analysis in BIM does not account for the energy associated with resource formation, recycling, and demolition. Therefore, a comprehensive method is required to analyze the true environmental impact of buildings. Emergy analysis can offer a holistic approach to account for the environmental cost of activities involved in building construction and operation in all its life cycle phases from resource formation to demolition. As such, the integration of emergy analysis with BIM can result in the development of a holistic sustainability performance tool. Therefore, this study aimed at developing a comprehensive framework for the integration of emergy analysis with existing Building Information Modeling tools. The proposed framework was validated using a case study involving a test building element of 8’ × 8’ composite wall. The case study demonstrated the successful integration of emergy analysis with Revit®2021 using the inbuilt features of Revit and external tools such as MS Excel. The framework developed in this study will help in accurately determining the environmental cost of the buildings, which will help in selecting environment-friendly building materials and systems. In addition, the integration of emergy into BIM will allow a comparison of various built environment alternatives enabling designers to make sustainable decisions during the design phase.

The kingpost was a vertical element that was used to support the structural strut in the deep excavation. The structural kingpost was commonly arranged by experienced engineers who used two-dimensional construction drawings. Thus, it was still time-consuming and error-prone. Currently, an available construction program has been developed to arrange the structural kingpost by identifying the clash problems in the 3D environment. However, they have a limitation for detecting the clash that was unable to visualize the concurrent clashes between kingpost and many underground structures. Then, the engineer cannot see all the clash incidents with each kingpost and move the kingpost to avoid the clashes successfully. Since the kingpost arrangement was still an inefficient practice that was limited in the visualization aspect, this research used engineering knowledge and advanced construction technology to detect and solve the clashes between kingposts and underground structures. The methodology used engineering knowledge of kingpost arrangement to develop the system modules by using a rule-based approach. Then, these modules were developed into the system by using visual programming of Building Information Modelling (BIM). To test the system, an underground structure from building construction was selected as a case study to apply the developed system. Finally, the finding of this study could overcome human judgment by providing less interaction in the kingpost arrangement and visualization improvement of clash occurrences in the 3D model.

The productivity of the construction sector in Spain is very low, as compared to other economic sectors, as with other countries in our environment. It takes us to a deep reflection on whether we are doing things right and what improvements can we introduce to increase production. These improvements must necessarily be technological and methodological, since there is a good training of the equipment both at the managerial level, as well as at the technical and in most of the labour levels, it is to exploit the full potential of new IT tools, especially Building Information Modelling (BIM) and the new methodologies that, from the industry, look for greater efficiency of the process and the elimination of all type of losses, like Lean Construction. A change of mentality, necessary to rethink the way of work in which we have been working for so many centuries, as the only possible paradigm, to replace confrontation as a way of producing construction through collaboration between all the agents involved in the work. We will speak in this article about Integrated Project Delivery (IPD), as one of the Lean methodologies that enable a profound improvement, we will see its definition, its essential components, and how it application can positively influence the construction process in Spain as it has already demonstrated in others.ResumenLa productividad del sector de la construcción en España es muy baja, tanto comparativamente con otros sectores económicos, como con la de otros países de nuestro entorno. Se hace necesaria una profunda reflexión sobre si estamos haciendo bien las cosas y qué mejoras podemos introducir para incrementar la producción. Estas mejoras han de ser necesariamente tecnológicas y metodológicas, ya que existe una buena capacitación de los equipos tanto a nivel directivo, como en la escala técnica y en muchos casos en la laboral, es decir, se trata de aprovechar todo el potencial de las nuevas herramientas informáticas, especialmente Building Information Modeling (BIM) y de las nuevas metodologías que, provenientes de la industria, buscan una mayor eficacia del proceso y la eliminación de todo tipo de pérdidas, como Lean Construction. Un cambio de mentalidad necesario, que pasa por replantearnos la forma de trabajo en la que llevamos tantos siglos empeñados, como único paradigma posible, sustituir el enfrentamiento, como forma de producir la construcción, por la colaboración entre todos los agentes intervinientes en la obra. Hablaremos en este artículo de los Métodos Colaborativos en construcción, que en inglés se han denominado Integrated Project Delivery (IPD), como una de las metodologías Lean que posibilitan una profunda mejora, veremos cuál es su definición, componentes esenciales, y cómo su aplicación puede incidir positivamente en el proceso constructivo de nuestro país al igual que ya lo ha demostrado en otros.

With the increasing number of nearly zero-energy buildings (NZEB) due to increase of global awareness on climate change, the new concepts of design and control must be developed because of great NZEB dependency on detailing and multidisciplinary approach. This paper proposes a three-level gateway control method for NZEB project delivery by using digital representation of the building in building information modeling (BIM) environment. These controls (C1, C2 and C3) are introduced before three main phases of any project delivery—design phase, construction phase and handover. The proposed project control procedure uses black-box building energy modeling within the BIM environment, so the paper explores the reliability of one tool for direct energy modeling within the BIM-authoring software. The paper shows two types of validation tests with satisfactory results. This leads to conclusion that analyzed tool for energy simulation within BIM environment can be used in a way that is described in a proposed project control procedure. For further research it is proposed to explore reliability of tools for energy simulation connected to other BIM-authoring software, so this project control procedure could be independent of BIM-authoring software used in the paper.

Temporary safety facilities (TSFs) are an essential support system providing necessary protection to workers during construction activities, which are targeted towards preventing the occurrence of incidents and accidents at the construction site; however, the schedule and location of installation and demolition of TSFs continue to rely on labor experience, and are often omitted from formal drawings or documents. This results in thousands of accidents in the construction industry, especially in construction small and medium-sized enterprises (SMEs) because of their several limiting factors; therefore, this study proposes automatic workspace planning for TSFs based on construction activities, which is a systematized approach for construction SMEs to practice occupational health and safety (OHS). By using building information modeling (BIM) and add-in algorithm, safety facilities can be simulated and visualized to integrate into the designated workspace. The developed system was implemented utilizing 4D-BIM for TSFs installation and validated with a case study on a residential building project. The result revealed that the visualized TSF produces a better understanding of safety measures with regard to project schedule. Additionally, TSFs workspace planning provides an affordable approach that motivates safety practices among the SMEs; consequently, the effectiveness of construction safety measures and their management is enhanced appreciably.

The purpose of this study is to verify the effectiveness of the constructivism education theory in building information modeling (BIM)/integrated project delivery (IPD) collaboration education by determining education methods that are most relevant to collaboration in the interaction process. We propose a BIM training model that enhances students’ satisfaction in class and collaboration. We aim to identify interrelationships between BIM collaboration education and constructivism theories, examining constructivism methods in BIM/IPD classes to discern which are the most suitable for improving and enhancing collaboration and the proposed education model. A model of the hypothesis “Constructivism Collaboration Process (CCP)” for BIM/IPD collaboration education was derived and a curriculum was created. The hypothesis model was tested by dividing into an experimental group and control group, and finally, prior and post-satisfaction and collaboration level assessments were performed in the BIM and IPD classes. After evaluating and analyzing the improvement in collaboration level and satisfaction, the results were derived for the hypothetical model of the “Constructivism Collaboration Process (CCP)” and the facts that can have a positive impact on BIM/IPD education.

The aim of the paper is to explain the basic principles of carrying out an inventory and follow-up of buildings and their condition assessment, by using the Full Interactive Visualization Method for Building Condition Assessment platform. It is a platform enabling the implementation of construction inventory based on the remote cooperation of many specialists in the field of, among others: building construction, architecture, civil engineering, photogrammetry, CAD, UAV. This type of cooperation is of particular importance especially in the context of the current epidemiological situation related to COVID-19. The idea of the presented platform fits into the broadly understanding of Building Information Modeling. After introducing the methodology, stages of the inventory and follow-up process carried out within the platform are illustrated and discussed on the basis of a case study. Based on the obtained results it can be concluded that the proposed methodology creates a convenient, efficient and inexpensive tool for massive inspection of building resources in large areas. The inventory is based primarily on high-quality photo and video material obtained from the deck of an unmanned aerial vehicle and the expert knowledge of the inspector conducting the inspection. By combining digital images data (photos, 3D model, orthophotos) with substantive data (facade element classification tables, wear / defect classification tables), we get a platform that allows intuitive access to viewing, classification, editing and analysis of selected data.
