1 Transition from building information modeling (BIM) to integrated digital delivery (IDD) in sustainable building management: A knowledge discovery approach based review
انتقال از مدل سازی اطلاعات ساختمان (BIM) به تحویل دیجیتال یکپارچه (IDD) در مدیریت پایدار ساختمان: بررسی روش کشف دانش مبتنی بر بررسی-2021
Over the past decade, building information modeling (BIM) and sustainability have attracted increased interest, with a concomitant rise in the number of related publications. However, research efforts made in BIM for sustainable building management, especially using in all four Integrated Digital Delivery (IDD) phases are minimal. Therefore, this study features a combined scientometric analysis and IDD thematic discussion examining 471 scholarly bibliographies accessed from the Web of Science (WoS) database. The purpose of this study is to statistically classify BIM-sustainability publications from 2007 to 2019 in order to understand the research status, key themes, trends, and future challenges to be addressed in the field of sustainable BIM. The most influential scholars, institutes, regions/countries, articles, and journals have been identified. Moreover, clustering analyses identified topics that sustainable BIM research tended to gravitate toward, such as cloud approaches, data sharing, life cycle energy efficiency, and informetric analysis. The top 100 most cited documents from WoS were also manually classified into four quadrants of IDD, namely design, fabrication, construction, and asset delivery and management. Ten BIMsustainability phenomena were observed throughout the life cycle of IDD. Finally, key research gaps and important areas for future research in this field were identified. The clearly delineated clusters and themes provide a practical overview and a deeper understanding of the current research progress of IDD for building sustainability, highlighting the challenges and research gaps for future research.

3 Automated clash resolution for reinforcement steel design in concrete frames via Q-learning and Building Information Modeling
رزولوشن برخورد خودکار برای طراحی فولاد تقویت کننده در قاب های بتنی از طریق یادگیری Q و مدل سازی اطلاعات ساخت-2020
The design of reinforcing steel bars (rebars) is critical to reinforced concrete (RC) structures. Generally, a good number of rebars are required by a design code, particularly at member connections. As such, rebar clashes (i.e., collisions and congestions) would be inevitable. It would be impractical, labor-intensive, and error-prone to avoid all possible clashes manually or even using standard design software. The building information modeling (BIM) technology has been utilized by the present architecture, engineering, and construction (ACE) industry for clash-free rebar designs. However, most existing BIM-based approaches offer the clash resolution strategy for moving components with an optimization algorithm, and are only applicable to the RC structures with regular shapes. In particular, the optimized path of rebars cannot be adjusted to avoid the obstacles, thus limiting the practical applications. Furthermore, most existing studies lack the learning from design code and constructibility constraints to realize automatic and intelligent arrangement and adjustment of rebars for avoiding the obstacles encountered in complex RC joints and frame structures. Considering these shortcomings, the authors have recently proposed an immediate reward-based multi-agent reinforcement learning (MARL) system with BIM, towards automatic clash-free rebar designs of RC joints without clashes. However, as the immediate reward is required in the MARL system for guiding the learning of a rebar design, it will not succeed in clash-free rebar designs of complex RC structures where immediate reward is often unavailable. In this study, this study further extends the previous work with Q-learning (a model-free reinforcement learning algorithm) for more realistic path planning considering both immediate and delayed rewards in clash-free rebar designs for real-world RC structures. In particular, the rebar design problem is treated as a path-planning problem of multi-agent system, where each rebar is deemed as an intelligence reinforcement learning agent. Next, by employing the Q-learning as the reinforcement learning engine, the particular form of state, action, and immediate and delayed rewards for the reinforcement MARL for automatic rebar designs considering more actual constructible constraints and design codes can be developed. Comprehensive experiments on three typical beam-column joints and a two-story RC building frame were conducted to evaluate the efficiency of the proposed method. The study results of paths of rebar designs, success rates, and average time confirm that the proposed framework with MARL and BIM is effective and efficient.

4 Work package-based information modeling for resource-constrained scheduling of construction projects
مدل سازی اطلاعات مبتنی بر بسته کار برای برنامه ریزی محدود منابع از پروژه های ساختمانی-2020
As an essential problem in construction management, the resource-constrained project scheduling problem (RCPSP) has been studied for decades; however, an integrated information model that fully supports the RCPSP solving process is still lacking. Though building information modeling (BIM) was proposed to meet the data requirements in the building life cycle, some scheduling and resource information are not considered in information transfers between the information model and the RCPSP mathematical model. This paper presents an integrated approach that enables fluent data flow from the information model to the RCPSP model for construction scheduling. Within this approach, a work package-based information model is proposed to capture all the required data of the RCPSP. Then, a semiautomatic method that integrates multisource data is introduced to form the proposed information model, and an adaptive data transmission method is used to support a designed multimode resource-constrained project scheduling problem (MRCPSP) model. The models and approaches are validated using the data of an actual project, demonstrating the feasibility and efficiency. This study contributes a novel integrated approach to formalizing a construction information model using a semiautomatic data integration approach, covering the information requirement and enables fluent data flow in the RCPSP solving process. Meanwhile, the work package-based information model is a successful attempt to introduce previouslygained knowledge into automatic schedule generation processes. Future work, such as extending the information model, creating new methods for RCPSP model generation, and data analytics, can bring new opportunities to apply more complex and intelligent methods in project scheduling and construction management.

5 Evaluating industrial modularization strategies: Local vs. overseas fabrication
ارزیابی استراتژی های مدولار صنعتی: محلی در مقابل تولید خارج از کشور-2020
Modularization is becoming more popular in industrial construction to enhance various project management aspects, including time, cost, safety, quality, and productivity. Although many studies have highlighted the differences between modular and conventional (stick-built) construction, little research is conducted to evaluate alternative fabrication strategies (e.g., overseas versus local fabrication). Some practitioners prefer to build modules locally, while some others prefer to outsource the module fabrication overseas and ship them to the industrial plant. This dramatically affects the decision on the size of the module envelope, and in turn, many other associated factors. The purpose of this study is to develop an integrated framework to evaluate different module fabrication strategies. This study employs various automation tools (e.g., building information modeling (BIM), simulation modeling) to quantify the impact of module fabrication strategies on any selected industrial project. The proposed framework considers various project aspects such as shipment and handling, fabrication, lifting, module resizing, and module assembly yard to find the best fabrication strategy. An actual case study, part of an industrial plant in Alberta, Canada, is presented in this paper to elucidate research contributions.

6 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.

7 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.

9 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.
