IFC-based process mining for design authoring
استخراج فرآیند مبتنی بر IFC برای تألیف طراحی-2020
Building Information Modelling (BIM) is defined as the process of creation and management of digital replica for building products in a collaborative design set-up. On this basis, BIM as a digital collaboration platform in AECO (Architecture, Engineering, Construction, and Operation) industry, can be upgraded to assist monitoring, control and improvement of the business processes related to planning, design, construction and operation of building facilities. The main problem in this regard, is the wastage of data related to activities completed by different actors during the project; and subsequently, the lack of analytics to discover latent patterns in collaboration and execution of such processes. The present study aims to enable BIM to capture digital footprints of project actors and create event logs for design authoring phase of building projects. This is done using files in IFC (Industry Foundation Classes) format, archived during the design process. We have developed algorithms to create event logs from such archives, and analyzed the event logs using process mining (i.e. process discovery, conformance checking and bottleneck analysis), to identify measures derived from as-happened processes. BIM managers can implement such measures in monitoring, controlling and re-engineering work processes related to design authoring. Two case studies were completed to validate and verify the products and findings of the research. Our results show that process models discovered/fine-tuned at various resolutions and from different perspectives (including ‘actor-centric’ and ‘phase-centric’ views) can provide a realistic view of the BIM project execution. This includes understanding the structure of collaboration and hand-over of work; evaluation of compliance with the BIM execution plan; and detection of bottlenecks and re-works. While the scope of the study has been limited to design authoring processes, this mindset can be extended to other BIM uses, and other phases (such as construction and operation) of building projects. Given the growing efforts on upgrading BIM to capture and formalize the lifecycle data on the products, processes and actors, this study can strongly support BIM managers with documentation and evaluation of the business processes and workflows in their project teams.

BIM-integrated management of occupational hazards in building construction and maintenance
مدیریت یکپارچه BIM از خطرات شغلی در ساخت ساختمان و نگهداری-2020
Health and safety in the construction sector are very important issues owing to the high accident rate in the industry. Recent studies have shown that implementing the building information modelling (BIM) methodology can improve the working conditions at construction sites and during building maintenance. Therefore, the European Union is promoting the development of projects through BIM. The government of Spain has established a roadmap to enforce the development of projects with BIM, and the integration of occupational health and safety in projects developed with BIM in Spain must comply with the current regulations. This study proposes a methodology—consistent with the requirements stipulated by the Spanish health and safety regulations— for its integration in the design phase of building projects developed using BIM.

Interoperability in building information modeling for AECO/FM industry
قابلیت همکاری در ساخت مدل سازی اطلاعات برای صنعت AECO / FM-2020
Data loss and communication problems may arise especially in complex construction projects, which in turn may result in poor project performance. Interoperability smooths communication while increasing information management quality. The aim of this paper is to investigate the interoperability research gaps and trends in Building Information Modeling (BIM) for architecture, engineering, construction, operation, and facility management (AECO/FM). This study adopted a holistic approach with a bibliometric search, a scientometric mapping and analysis of interoperability in BIM research. Data about interoperability in BIM were collected through an examination of 477 articles that were selected from the Scopus database. This study contributes to the body of knowledge by highlighting the research trend and gaps in key areas, and their relationship with interoperability in BIM. As results suggest, future studies should focus on interoperability in BIM to increase knowledge-integrated, ontology-based, IT-based managed, collaborative, automated, well-visualized, and sustainable outcomes throughout the project lifecycle.

From BIM to extended reality in AEC industry
از BIM تا واقعیت گسترده در صنعت AEC-2020
In the Architecture, Engineering, and Construction (AEC) industry, Extended Reality (XR) technologies that simulate a construction project in a multidimensional digital model and present multiple aspects of a project can be a tremendous help in all stages of a project. This study aims to identify the outsourcing patterns for such technologies among construction project stakeholders. Currently, there is limited literature about XR technologies, and because of it, the sections containing the results of this study are as follows: (1) a concise review of the most recent VR, AR, and MR technologies in the design and construction industry; (2) an introduction to the most commonly used wearable XRs on the market in terms of features, ease of use, and their specifications; (3) a summary of the different methods and software used for converting the BIM model to VR, AR, and MR; and (4) finally, a case study included the integrated definition function (IDEF0) model that details how to convert the BIM model of the NASA-Mars habitat project to a VR and MR model that uses Oculus Rift, HTC Vive, Samsung HMD, and Microsoft HoloLens headsets. Overall, this study provides a comprehensive review regarding using XR to solve a variety of construction project management issues effectively and efficiently. More importantly, this study provides a roadmap for future efforts involving the implementation of XR technologies in the AEC industry.

A building information modeling-based carbon emission measurement system for prefabricated residential buildings during the materialization phase
یک سیستم اندازه گیری انتشار کربن مبتنی بر ساخت مدل سازی اطلاعات برای ساختمانهای مسکونی پیش ساخته در مرحله تحقق-2020
This study develops a carbon emission measurement system for prefabricated residential buildings (PRBs) during the materialization phase based on building information modeling (BIM) and a carbon emission measurement model. The model is constructed using the carbon emission coefficient method. For more accurate measurement, the materialization phase of PRBs’ carbon cycle is re-defined into five stages (material production, material transportation, component production, component transportation, and construction). This innovative system also incorporates Microsoft Access-based databases for data management. The implementation of the system in a PRB project in Shenzhen, China revealed that over 90% of carbon emissions were generated in the building material production and construction stages, and overall carbon emissions per unit volume of all the prefabricated components were 764.87 kg/m3, 20.11% lower than those of the cast-in-situ parts. Compared with results obtained from the traditional method, the system’s percentage error was 6.52%, showing good reliability in carbon emission measurement. The discrepancy was reasonably justified by inevitable material losses and transportation distances. It is concluded that the measurement system can accurately predict PRB projects’ carbon emissions in project planning and early design, identify key areas for carbon emission pre-control, and facilitate dynamic management of carbon emission reduction during the materialization phase.

Potential of big visual data and building information modeling for construction performance analytics: An exploratory study
پتانسیل داده های بصری بزرگ و ساخت مدل سازی اطلاعات برای تجزیه و تحلیل عملکرد ساخت: مطالعه اکتشافی-2017
The ever increasing volume of visual data due to recent advances in smart devices and camera-equipped platforms provides an unprecedented opportunity to visually capture actual status of construction sites at a fraction of cost compared to other alternatives methods. Most efforts on documenting as-built status, however, stay at collecting visual data and updating BIM. Hundreds of images and videos are captured but most of them soon become useless without properly being localized with plan document and time. To take full advantage of visual data for construction performance analytics, three aspects (reliability, relevance, and speed) of capturing, analyzing, and reporting visual data are critical. This paper 1) investigates cur rent strategies for leveraging emerging big visual data and BIM in construction performance monitoring from these three aspects, 2) characterizes gaps in knowledge via case studies and structures a road map for research in visual sensing and analytics.
