As the construction industry continues to advance technologically, the adoption of sensing technologies is gradually gaining momentum. Sensing technologies (such as radio frequency identification systems, laser scanners, cameras, and global position systems) play a significant role in reducing costs, improving project productivity, and enhancing workers' health and safety. This has prompted the need for a workforce with the required skills and knowledge for deploying sensing technologies in the industry. Since construction-related education is aimed at preparing students for the future of the industry, it is important to investigate the industry’s expectations for equipping the future workforce with the required skills. This study adopts a mixed-method research approach. Data are collected from surveys, case studies, and a focus group discussion with industry practitioners. The data elucidate participants’ perceptions, attitudes, and beliefs regarding: the skills required, and level of knowledge transfer required to advance sensing technologies on construction projects, and the value and anticipated demand for these skills. The findings also revealed the extent to which sensing technologies are deployed in the industry and the benefits driving the adoption of these technologies. The results reveal a high rate of adoption of sensing technologies amongst industry practitioners and inform construction applications and skills to be taught in construction engineering education. This study contributes to the existing scarce literature on the knowledge and skill demands of the industry to implement sensing technologies. The findings provide critical feedback for expanding the construction education curriculum to meet up the industry’s demand and adequately prepare the future workforce.

Building Information Modelling (BIM) is a revolutionary invention within the construction industry that essentially aids the design, construction and management of construction projects throughout their lifespan. Globally, the Architecture, Engineering, and Construction (AEC) industry has for decades progressively adopted and implemented BIM. While there are several papers in this context, none have tried to extensively document BIM’s comprehensive contributions and uses in the construction phase. Therefore, this paper aims to identify BIM’s various contributions and uses in the construction phase and analyze publication trends, co-occurring keywords, contributing authors and countries. A systematic overview approach was used to review published articles on state-of-the-art of BIM in construction, supported by bibliometric network mapping analysis. A total of 409 documents were extracted and analyzed. The study’s findings document BIM’s various uses and contributions to the AEC industry, such as simulation of each stage of the construction process, virtual presentation of the building and site, visualization of progress, management of construction work, enhancement of safety, communication and collaboration, quick generation of reliable and accurate cost estimates, assistance in the fast realization of return on investment (ROI), and serving as a platform that hosts and documents various technological tools used during the construction phase. The bibliometric analysis reveals the most contributing scholars, countries, document sources, trend network mapping of co-occurring keywords, and publication trends. The primary practical implications of this study’s discoveries can be exploited as a basis for further research and to influence the future direction of BIM in the AEC industry. The findings will enhance the wider spread, application and understanding of BIM in the AEC industry, thereby increasing BIM awareness and knowledge globally.

While the advancement of visualization technologies—virtual-reality, augmented-reality, mixed-reality, and extended reality—has long produced opportunities to create more realistic simulated environments to provoke and study natural human behavior, recent interest in applying 360° panoramic visualizations has been increasing across several disciplines due to these technologies’ lower costs, higher presence, and greater immersive-ness. However, the variety of applications of 360° panoramas (both images and videos) is limited in the architecture, engineering, and construction (AEC) domain compared to other domains. This paper systematically presents an in-depth understanding of 360° panorama research trends and reveals the challenges and opportunities for future research in the AEC area. In particular, this systematic review analyzed eighty studies across two decades (2000-2022) to consider 360° panoramas’ application areas, methodologies, potential benefits, challenges, best practices, and future research directions for both AEC and non-AEC domains. Several prevalent application domains in AEC—namely architectural studies, construction education and training, construction visualization and progress monitoring, and cognitive analysis and human behavior in the construction industry—were identified. This paper indicates that 360° panoramas provide a higher sense of presence than conventional simulation methods (e.g., virtual reality). Moreover, pairing 360° panorama technologies with a head-mounted display significantly increases immersion when compared with other display options. Lastly, limitations of 360° panoramas, such as cybersickness and technical properties, are discussed. This paper is expected to shed light on the potential of these state-of-the-art technologies in the AEC domain, which can serve both academia and industry.

The construction sector is undergoing a digital transition. Local authorities have adopted geographic information systems (GISs) to plan their territories and structure their services, such as transport. Simultaneously, building information modelling (BIM) has demonstrated its advantages during the design and construction phases of structures. An infrastructure project can rely on these two technologies to plan its implementation (GIS), to complete its design and construction (BIM), or to manage associated services, such as mobility (GIS). However, road maintenance, an important part of the infrastructure’s life cycle, is not yet covered by these technologies. Road maintenance necessitates a comprehensive view of the infrastructure and its interactions with other real-world objects (e.g. vegetation, technical networks, or vehicles). Moreover, road managers are the local authorities that already use GISs. For these reasons, a GIS is suitable for fulfilling road maintenance requirements. This study presents a spatial framework (GIS) developed for road management. Applying it to a specific case study provides insights on the organisation of the spatial road framework which can be adapted to the infrastructure’s environment management. The spatial dimension must allow for the representation of the road and its components, including pavements and their dependencies. The structural dimension must be detailed to describe the layers, their formulations, and their thicknesses. The condition of the road must be described concisely so that the managers can plan maintenance.

Recognising activities of construction equipment is essential for monitoring productivity, construction progress, safety, and environmental impacts. While there have been many studies on activity recognition of earth excavation and moving equipment, activity identification of Automated Construction Systems (ACS) has been rarely attempted. Especially for low-rise ACS that offers energy-efficient, cost-effective solutions for urgent housing needs, and provides more affordable living options for a broader population. Deep learning methods have gained a lot of attention because of their ability to perform classification without manually extracting relevant features. This study evaluates the feasibility of deep sequence models for developing an activity recognition framework for low-rise automated construction equipment. Time series acceleration data was collected from the structure to identify major operation classes of an ACS. Long Short Term Memory Networks (LSTM) were applied for identifying the activity classes and the performance was compared with that of traditional machine learning classifiers. Diverse augmentation methods were adopted for generating datasets for training the deep learning classifiers. Several recently published literature seem to establish the superiority of complex deep learning techniques over traditional machine learning algorithms regardless of the application context. However, the results of this study show that all the conventional machine learning classifiers perform equivalently or better than deep learning classifiers in identifying activities of the ACS. The performance of the deep learning classifiers is affected by the lack of diversity in the initial dataset. If the augmented dataset significantly alters the characteristics of the original dataset, it may not deliver good recognition results.

Digital transformation (DT) is expected to contribute to the construction industry's ability to meet climate and sustainable challenges and increase companies' productivity. This study aims to explore requirements for, and factors affecting DT in the construction industry. This research goes beyond the technology perspective and focus on factors needed to transform the potential of digitalisation to benefits for organisations in the construction industry. A structured literature review is performed where knowledge gaps are identified, and a framework is developed that maps the required changes, as well as the associated challenges, constraints, and implications. The construction industry´s business-to-business logic, and the fragmented and project-based structure is found to have impact on the industry´s development within DT. Mainly regarding the DT aspects disruption, structural changes, organisational barriers, and the central aspect value creation. The understanding of DT by scholars and practitioners in the construction industry is found immature and this calls for further research. The research contributes to understanding of the concept DT and proposes, based on earlier DT literature, an adjusted framework for DT in construction, and points out key areas where research in construction has gaps to fill.

The development of software tools is a collaborative process involving both the domain experts and the software engineers. This requires efficient communication considering different expertise and perspectives. Additionally, the two groups utilize language and communication tools in disparate ways. This, in turn, may lead to hidden misunderstandings in the requirement analysis phase and potentially result in implementation problems later on, that is difficult and costly to correct. In this paper, we demonstrate the above mentioned challenge via a use case from the tunneling domain. In particular, during the requirement analysis phase for a software capable of handling the data model of the subsoil. The domain experts in the field can best express the complexity of their domain by describing its artifacts, which in most cases are incomprehensible to the software engineers. We outline a method that interleaves requirement analysis and software modeling to enable an iterative increase of the accuracy and completeness of the information extracted from those artifacts and integrated into a flexible software model, which can produce testable software code automatically. Furthermore, we present a prototypical implementation of our method and a preliminary evaluation of the approach.

The paper is concerned with the development and comparison of alternative machine learning methods of determining the type of truck crossing a bridge from the dynamic response it induces within the bridge structure, the so-called weigh-in-motion problem. Weigh-in-motion is a rich engineering problem presenting many challenges for current machine learning technologies, and for this reason is proposed as a benchmark for guiding and assessing advances in the application of this field of artificial intelligence. A review is first provided of existing methods of determining truck types and loading attributes using both machine learning and heuristic search techniques. The most promising approach to date, that of artificial neural networks, is then compared to support vector machines in a comprehensive study considering a range of configurations of both modeling techniques. A local scatter point smoothing schema is adopted as a means of selecting an optimal set of design parameters for each model type. Three main model formats are considered: (i) a monolithic model structure with a one-versus-all truck type classification strategy; (ii) an array of sub-models each dedicated to one truck type with a one-versus-all classification strategy; and (iii) an array of sub-models each dedicated to selecting between pairs of trucks in a one-versus-one classification strategy. Overall, the formats that used an array of sub-models performed best at truck classification, with the support vector machines having a slight edge over the artificial neural networks. The paper concludes with some suggestions for extending the work to a broader scope of problems.

Fires in under-construction threaten to worker safety and have a lot of negative impacts on many aspects of construction that were reported the past few years. Many constructions do not possess the permanent fire protection system, and only rely on the fire extinguisher or water tank to extinguish the fire. Moreover, a construction site has numerous features that make its uncommon and unanticipated structure. In a construction environment, changing is one of the characteristics that make it unique compared to others. Due to the dynamic nature of construction, the fire safety plan in construction needed to be reviewed and updated according to construction progress. The convention approach or manual process to develop the fire safety plan for a construction project can be a time-consuming and enormous labour-intensive task. BIM technology and Game engine can present the object in 3D and provide programming for the rule-based modelling. Therefore, this paper proposes a framework to assess the fire extinguisher installation plan (FEIP) and recommend the locations of fire extinguisher by considering the dynamic nature of construction. This research develops the prototype that enables the users to define the parameters for the fire extinguisher installation plan such as finished and unfinished building objects (walls, stairs and slabs), exists, the locations of fire extinguishers (FE) and flammable substances (FS). This prototype provides the appropriate locations of fire extinguishers and shows the unsafe area. To validate the proposed approach, the case study using the sample BIM model is executed. The proposed system is expected to have the capability of assisting the safety engineers in developing and assessing the fire extinguisher installation plan.

Many constructions do not possess the permanent fire protection system, and only rely on the fire extinguisher or water tank to extinguish the fire. Moreover, a construction site has numerous features that make its uncommon and unanticipated structure. In a construction environment, changing is one of the characteristics that make it unique compared to others. Due to the dynamic nature of construction, the fire safety plan in construction needed to be reviewed and updated according to construction progress. The convention approach or manual process to develop the fire safety plan for a construction project can be a time-consuming and enormous labour-intensive task. BIM technology and Game engine can present the object in 3D and provide programming for the rule-based modelling. Therefore, this paper proposes a framework to assess the fire extinguisher installation plan (FEIP) and recommend the locations of fire extinguisher by considering the dynamic nature of construction. This research develops the prototype that enables the users to define the parameters for the fire extinguisher installation plan such as finished and unfinished building objects (walls, stairs and slabs), exists, the locations of fire extinguishers (FE) and flammable substances (FS). This prototype provides the appropriate locations of fire extinguishers and shows the unsafe area. To validate the proposed approach, the case study using the sample BIM model is executed. The proposed system is expected to have the capability of assisting the safety engineers in developing and assessing the fire extinguisher installation plan.","PeriodicalId":51624,"journal":{"name":"Journal of Information Technology in Construction","volume":"1 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48471237","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}

There has been an increasingly global tendency in the adoption of Building Information Modeling (BIM) paradigm in Architectural, Engineering, and Construction (AEC) projects. At the same time, Structural Optimization (SO) has received a lot of attention in the construction industry to reduce material and to enhance structural performance. However, the lack of communication between structural engineer and architect is a well-known problem discussed in the literature. This can lead to inefficient projects, thus increasing cost and time. The purpose of this work, thus, is to understand how SO can be inserted in a BIM project, specifically analysing the information exchanges between architects and structural engineers, to mitigate the problem related to lack of communication. The investigation included a systematic literature review to comprehend the current scientific scenario in these areas. It identified that there is still a research gap related to the adoption of SO to facilitate the communication between architects and structural engineers in a BIM environment. To help answer this question, an Information Delivery Manual (IDM) structure was developed which maps the information flow to connect architects and engineers through SO in a BIM environment, aiming to optimize the information exchanges. By applying the methodology to three experiments of increasing complexity, the proposed framework proved to improve the collaboration issue beyond other project benefits, such as reduction of material consumption, improvement of sustainability indexes, and structural performance. Thus, the main finding of this study is that the connection between BIM and SO can improve the collaboration between these two players in the early design stages and, thus, it can potentially lead to a more efficient design process. More studies are still necessary to solve technological barriers related to software interoperability.
