To address this research question, this study aims to conduct a state-of-the-art review of AI in CC in the CI by providing a qualitative discussion of the main research hotspots, research gaps, and future research directions. This review study used a four-step bibliometric-systematic review approach consisting of literature search, literature screening, science mapping analysis, and qualitative dis-cussion. The results found four main research hotspots, namely (1) construction project performance indicators, (2) data analysis and visualization, (3) construction quality control and safety, and (4) construction energy efficiency. These findings would provide valuable insights for scholars and practitioners seeking to understand and integrate AI and CC technology applications in the CI. This review study will lay a better foundation for future developments in construction project management processes, data-sharing protocols, real-time safety monitoring, and ethical implications of AI and CC technologies.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141801401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern techniques are essential to create new tools that outperform current cost estimation. This study introduced the Least Square Moment Balanced Machine (LSMBM), AI-based inference engine, to improve construction cost prediction accuracy. LSMBM considers moments to determine the optimal hyperplane and uses the Backpropagation Neural Network (BPNN) to assign weights to each data point. The effectiveness of LSMBM was tested by predicting the construction costs of residential and reinforced concrete buildings. Correlation analysis, PCA, and LASSO were used for feature selection to identify the most relevant variables, with the combination of LSMBM-PCA giving the best performance. When compared to other machine learning models, the LSMBM model achieved the lowest error values, with an RMSE of 0.016, MAE of 0.010, and MAPE of 4.569%. The overall performance measurement reference index (RI) further confirmed the superiority of LSMBM. Furthermore, LSMBM performed better than the Earned Value Management (EVM) method. LSMBM model has proven to enhanced the precision in predicting cost estimates, facilitating project managers to anticipate potential cost overruns and optimize resource allocation, provide information for strategic and operational decision-making processes in construction projects.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141798663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing 5D BIM tools are used to estimate the cost of projects during the preconstruction period. There is a lack of integration between the 5D BIM models, existing progress monitoring tools, and payment systems used in construction. Lack of standardization in the use of model elements through the project lifecycle has also been identified as one of the factors limiting automation in 5D BIM. Construction project monitoring can be automated by combining modern technologies that allow for visualization of building progress (Laser scanners, computer vision) with 5D BIM cost estimation tools. These project monitoring tools can be combined with Artificial Intelligence (AI), and Smart contracts to develop an integrated lifecycle system for cost management in construction.\u0000This paper examines existing systems used in 5D BIM to develop integrated practices and systems that will streamline the process of cost estimating, cost monitoring, cost control, and cash flow in the construction supply chain. This will reduce the inefficiency that exists today with traditional contracts and payment applications that do not interact with the 5D BIM application. By leveraging a standardized classification ID system throughout a project life cycle and applying AI and smart contract, features like cost estimation cost control, and payments can be fully streamlined, integrated, and automated. A case study of an existing construction project utilizing 5D BIM was examined. According to the study, 5D BIM is used in the pre-construction stage of a cost estimation project. It was also revealed that 5D BIM improves project cost visualization and budget control.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141799891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, CDEs are used very limitedly in the construction industry. One of the reasons for the limited implementation of CDEs can be associated with the need for construction companies' knowledge about the positive impacts of CDEs on performance management. A well-structured CDE can provide countless benefits and promote long-term improvements in construction projects and organizations, increasing their business success. Despite the acknowledged importance of CDEs, research needs to investigate the impacts of CDEs on project and organizational performance considering the construction KPIs. This study aims to reveal (1) how the CDEs facilitate performance measurement in the construction phase of BIM-based projects and (2) how the CDEs positively affect the project and organizational performance in the construction phase of BIM-based projects. This scope uses seven construction KPIs: time, cost, quality, safety, productivity, organizational sustainability, and client satisfaction. This study conducts a systematic literature review, semi-structured interviews with five subject-matter experts, and the two-rounded Delphi method to fulfill the research objective. The results show that implementing the CDEs in the construction phase of BIM-based projects positively affects productivity, quality, and time KPIs, followed by organizational sustainability, cost, client satisfaction, and safety, respectively. This research contributes to collating and uncovering the added value of CDEs for the organizational and performance management of BIM-based projects. Accordingly, this study would increase the awareness of construction companies about ‘how they can benefit from the data located in the CDEs from project management through knowledge management in the best way'.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140686450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FM requires a vast range of data arising from diverse activities, which demands tools and processes for data collection and management. The Building Information Modeling (BIM) methodology implies an integrated information management process which helps in effective communication and information flow. Therefore, adopting BIM to support FM (BIM-FM) has become the subject of academic and industry interest. When BIM methodology is implemented, information models are the main information repository, while information requirements set the guidelines for their development. The EN ISO 19650 series and EN 17412-1 are currently the most recent standards in the European context to assist the development of information requirements. However, there is still a lack of research on their detailed application to real-case scenarios. In this context, the present article cooperates with the broad adoption of BIM-FM by presenting the establishment of information requirements to inform the development of an information model for the ongoing operational phase of a university canteen, focusing on developing Exchange Information Requirements (EIR), and including other activities of ISO19650’s information management process to demonstrate the applicability of the requirements. The procedure applies the Level of Information Need (EN 17412-1) as the framework for defining the extent and granularity of the information requirements, and it employs the IFC schema to establish the required alphanumerical information. The paper thoroughly discusses the decision-making process and its implications, working as a detailed demonstration of the standards applied in a case study. The results demonstrate the efficiency of the purpose-driven process based on standardization, and the information model developed from the requirements is proven to deliver the required information accurately. Ultimately, the paper results in a robust source for process replication on FM real-case scenarios.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140686895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While decision-making methods have been used to address some of the existing challenges such as inconsistency, they also have challenges including variation between comparison during the actual prioritization task as opposed to those outside of maintenance context. The data analytics and machine learning methods can help with extracting meaningful and valuable information, finding patterns, and drawing conclusions from the available data. Such methods have benefits including faster prioritization performance leading to less failure and downtimes, reduced impact of knowledge loss, decreased cognitive workload, identification of errors for adjusting the system, and determination of important factors impacting work order processing to support the development of data requirements. This paper summarizes the background on existing gaps in processing maintenance work orders and provides an overview of machine learning methods to support prioritizing work order. The paper then discusses the work order data of an educational facility as a case study, presents information on data exploration and data cleaning approach, and provides insights gained from their maintenance work order data. The insights gained present challenges such as submission of multiple work orders as one, missing data for certain criteria, long durations for addressing some of the work orders, and the correlation between criteria collected by the facility and the schedule. The paper continues by implementing artificial neural networks to benefit from work order data collected for automatically prioritizing the future work orders. The results present the optimum neural network structure based on mean squared error estimated and provides the best value for each parameter used for the development of the model. The accuracy and efficiency of the developed model was validated by the facility experts of the educational facility.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140689575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies in this area are mostly focused on building construction environments. Worker activity identification and classification in mobile work zone operations is more challenging, due to more dynamic operating environments (e.g., more movements, weather, and light conditions) than building construction activities. In this study, we propose a deep learning (DL) based classification model to classify workers’ activities in mobile work zones. Sensor locations are optimized for various mobile work zone operations, which helps to collect the training data more effectively and save cost. Furthermore, different from existing models, we innovatively integrate transportation and construction domain knowledge to improve classification accuracy. Three mobile work zone operations (trash pickup, crack sealing, and pothole patching) are investigated in this study. Results show that although using all sensors has the highest performance, utilizing two sensors at optimized locations achieves similar accuracy. After integrating the domain knowledge, the accuracy of the DL model is improved. The DL model trained using two sensors integrated with domain knowledge outperforms the DL model trained using three sensors without integrating domain knowledge.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This leads to studies related to value management in project and organizational contexts, especially for the public sector. However, the empirical measurement of BIM value must be done systematically to produce more accurate and valid results for applications. Therefore, this study attempts to pave the way for development of Cost Benefit Analysis (CBA) of BIM implementation in Malaysian Public Works Department (PWD) by determining the BIM benefit attributes that have been realized and cost attributes that are needed for that. A total of 150 survey questionnaires were distributed to four design departments in Malaysian PWD Headquarter (HQ) to be rated using 5-points Likert’s interval scale. Based on the data collected, the results were analyzed using Confirmatory Composite Analysis (CCA) as a method of confirming measurement quality (MCMQ) in Partial Least Square Structural Equation Modelling (PLS-SEM). The study model was conceptualized as a reflective-formative type II Hierarchical Component Model (HCM). The results indicate key benefit attributes and cost attributes related to two main BIM uses in Malaysian PWD current practices which are the ‘design review’ and ‘automated clash detection’. Based on the final form of the model, there was a total of eight key benefits of BIM implementation which are ‘lower cost’, ‘better scenario and alternative analysis’, ‘improved communication’, ‘improved coordination’, ‘improved output quality’, ‘better change management’, ‘less rework’, and ‘fewer error’. On the other hand, three cost attributes that were confirmed are ‘software related investment’, ‘hardware related investment’ and ‘infrastructure cost’. This paper provides researchers on the approach of confirming key items needed to measure BIM value and is hoped to assist the value analyst to perform the Value Management (VM) analyses for their projects.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140686900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple studies are dedicated to examining the difficulties encountered by the construction industry, as well as the advancement of technologies in this field. However, further research is required to examine the extent to which construction professionals are aware of and acknowledge new technologies, as well as their expectations regarding the problem-solving capabilities of Construction 4.0 technologies. This study investigates the degree of awareness of Construction 4.0 technologies, the significance of the primary challenges frequently encountered in construction projects, the advantages expected from these technologies, and the level of consensus among various groups of construction professionals on these matters. Based on an extensive examination of existing literature, 13 specific technologies related to Construction 4.0, 11 primary challenges and 17 anticipated advantages were identified. A survey was devised and administered to Turkish construction experts, resulting in the collection of 188 valid responses. The gathered data was subsequently subjected to statistical analyses. The investigated data led to the conclusion that there was a substantial agreement among the respondents regarding the level of recognition of Construction 4.0 technologies, the primary challenges in construction projects, and the anticipated advantages of these technologies.

Using Digital Twins (DTs) can aid in making O&M more effective and efficient, leading to time and cost savings. The concept of DT started in the Aerospace domain, and other industries eventually adopted it. DTs are a new concept to the Architecture, Engineering, Construction, and Operations (AECO) Industry, and there is a lot of confusion around this concept. The purpose of this paper is to provide a DT definition along with a classification structure to create a common ground for understanding DTs in the AECO industry, which leads to easier adoption of DTs. A systematic literature review was completed to identify the existing DT definitions and classification approaches. Then, through a content analysis, the core components of definitions were extracted. The identified components were used to develop a comprehensive and inclusive DT definition for the AECO industry, using the domain language. In a similar fashion, existing DT classification structures were studied, and their components were identified through content analysis. Using the identified components, a DT classification structure was proposed for the AECO industry using domain concepts and terms. The results were validated and refined through a series of semi-structured expert interviews and surveys. Interviewees and survey participants comprised DT experts from academia and industry with diverse backgrounds. The components of the proposed DT definition include virtual representation, data connection between physical and digital entities, analysis, actuation, and frequency of updates. The classification structure consisted of three DT categories, namely Digital Twin Prototype (DTP), Digital Shadow (DS), and Cyber-Physical System (CPS).","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140365459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
