Abstract

Construction project management covering various aspects such as planning, coordinating, directing, scheduling, monitoring and control. Pre-construction services are used in planning a construction project before the actual construction begins. However, various problems happened at the pre-construction planning stage. This paper present an overview of the major problems in pre-construction stage and look at the potential of using augmented reality technology to overcome those problems. It was found that, at the pre-construction stage, good planning can not be done by the project teams especially to engineers and contractors due to the lack of supporting data, particularly when it involves information relating to underground utilities such as telecommunications, gas, electricity, water and sewerage. There are several approaches that can been undertaken in pre-construction services, especially in making an informed decision. The potential technology is using Augmented Reality (AR)-based approach in pre-construction service. Augmented reality is the integration of digital information with the users environment in real-time. It was one of the tool that support the concept of cyber-physical systems (CPS). CPS is the integration systems between computational network and physical processes. Currently, there are many fields utilised the application of AR such as medical, militiry, vehicles, gaming and navigation. This paper presents the applications of an AR-based approach to medical and gaming industry and explore the potential of using AR in pre-construction. The finding shows that the AR is a potential decision support tool that will speed up the planning process of the project team in the pre-construction phase in real-time.

This study presents the development of a comprehensive model for evaluating the level of readiness of buildings for digital transformation during the pre-construction phase. The proposed model utilizes structural equation modeling (SEM) and includes a full list of key factors for achieving success. This tool is designed to support industry stakeholders in assessing operational efficiency in terms of digital transformation readiness in the pre-construction phase (DTRPC) and analyze the effectiveness and limitations of DTRPC across various management levels. Key success factors were identified through interviews with experts and a review of the relevant literature. These variables were then validated through two rounds of the 8 Delphi technique, which included the input of 13 highly qualified experts. Finally, an online questionnaire was disseminated to industry professionals, who assessed the factors’ relative levels of significance. Questionnaire responses were collected from a sample of 300 individuals from different professional fields. SEM was then used to quantitatively analyze the relationships between the various components of the DTRPC success factors. The goal was to determine the impact of each construct on the overall level of readiness. The model underwent a thorough evaluation to determine its strength and stability across several parameters, including accuracy, conformity to multivariate normalcy, and reliability and validity. A hypothesis analysis was also conducted. The collected data were used to develop the proposed DTRPC model, consisting of 30 essential performance indicators grouped into four categories. The use of SEM uncovered a significant correlation between the operational indicators of these critical factors and the construct groups, as well as the influence of effective DTRPC constructs on overall project performance. This research expands the current knowledge by identifying important indications for evaluating the success of the DTRPC model and using them to create a comprehensive global SEM that can be used as a tool for measuring readiness at the pre-construction stage. This has the potential to provide essential assistance to organizations, project managers, and policymakers in making informed decisions.

To effectively use augmented reality (AR) technology for end-user involved design collaboration, it is necessary to ensure the effectiveness of the AR system from the end-user’s perspective. However, most efforts have mainly focused on technological development, and as such, limited attention has been paid to the end-user’s application of the AR system. Therefore, this study investigates how the AR system affects architectural design review based on the user’s perspectives. Three different display systems presenting a 3D model including a 2D screen, VR, and AR were tested, and a total of 76 participants evaluated visual presentation quality, perceived acceptability, and user experience according to their usage of the visualization platform types during the design review activities. Compared to other systems, the results indicated that the AR system could be more effective in reviewing the visual elements of a building. Furthermore, AR showed the highest ratings for acceptance level and user experience. The innovation provided by AR created a positive user experience, despite its remaining challenges to be resolved in terms of functionality. Since it is expected that the use of AR can be promoted by overcoming certain technological limitations, this study contributes to guiding AR system applications for end-users involved in the design review process.
... For example, the iGeology application (Westhead et al., 2012) provides interactive geological maps of the United Kingdom using an AR technique developed by the British Geological Survey (BGS). Other studies have proposed similar mobile device-based applications for visualizing subsurface geological structures for the mining industry (Mathiesen et al., 2012 ) and for visualizing underground infrastructures during preconstruction stages (Khalid et al., 2013; Schall et al., 2013 ); however , these applications have been limited to proposed or prototype systems. Generally, the recent development of AR systems has resulted in geological map displays on mobile devices but without sufficient detail about the environment, and they do not incorporate borehole data or related datasets. ...

Boring logs are widely used in geological field studies since the data describes various attributes of underground and surface environments. However, it is difficult to manage multiple boring logs in the field as the conventional management and visualization methods are not suitable for integrating and combining large data sets. We developed an iPad application to enable its user to search the boring log rapidly and visualize them using the augmented reality (AR) technique. For the development of the application, a standard borehole database appropriate for a mobile-based borehole database management system was designed. The application consists of three modules: an AR module, a map module, and a database module. The AR module superimposes borehole data on camera imagery as viewed by the user and provides intuitive visualization of borehole locations. The map module shows the locations of corresponding borehole data on a 2D map with additional map layers. The database module provides data management functions for large borehole databases for other modules. Field survey was also carried out using more than 100,000 borehole data.

The rapid advancement of digital technology has enabled digital transformation across various sectors, including construction. The construction industry has long been associated with conventional, labor-intensive practices that can adversely influence the entire construction process. However, this culture is changing as key players in the sector are progressively identifying and embracing the vast opportunities and associated benefits of using digital tools and technologies to improve the performance and outcomes of the overall project lifecycle. To this end, this study uses the Delphi technique to identify 70 factors that contribute to the digital transformation of the construction industry, categorizing them into five groups: management, design, technology, policy, and infrastructure. Delphi analysis is used to examine the critical success factors for digital transformation identified in the literature and rate their importance during the preconstruction, construction, and facility management phases. Furthermore, this research results in the introduction of the Digital Transformation Level of Readiness Framework (DTRLF) to help facility management firms, clients, organizations, contractors, and designers comprehend the implementation of digital transformation within their respective domains and support decision-makers in establishing action to adapt related technologies in their respected project phases.

Augmented reality (AR) makes it possible to create games in which virtual objects are overlaid on the real world, and real ob-jects are tracked and used to control virtual ones. We describe the development of an AR racing game created by modifying an ex-isting racing game, using an AR infrastructure that we developed for use with the XNA game development platform. In our game, the driver wears a tracked video see-through head-worn display, and controls the car with a passive tangible controller. Other players can participate by manipulating waypoints that the car must pass and obstacles with which the car can collide. We dis-cuss our AR infrastructure, which supports the creation of AR applications and games in a managed code environment, the user interface we developed for the AR racing game, the game's soft-ware and hardware architecture, and feedback and observations from early demonstrations.

The impressive development of medical imaging technology during the last decades provided physicians with an increasing amount of patient specific anatomical and functional data. In addition, the increasing use of non-ionizing real-time imaging, in particular ultrasound and optical imaging, during surgical procedures created the need for design and development of new visualization and display technology allowing physicians to take full advantage of rich sources of heterogeneous preoperative and intraoperative data. During 90's, medical augmented reality was proposed as a paradigm bringing new visualization and interaction solutions into perspective. This paper not only reviews the related literature but also establishes the relationship between subsets of this body of work in medical augmented reality. It finally discusses the remaining challenges for this young and active multidisciplinary research community.

It is argued that due to construction peculiarities, supply chain management has four specific roles in construction. Practical initiatives in each role to advance the construction supply chain are analysed. The present status of construction supply chains is investigated by means of case studies and a comparison with previous research. Three main conclusions are drawn regarding the present status. Firstly, even in normal situations the construction supply chain has a large quantity of waste and problems. Secondly, most of these are caused in another stage of the construction supply chain than when detected. Thirdly, waste and problems are largely caused by obsolete, myopic control of the construction supply chain. These results concur with the findings made on make-to-order supply chains in general. Finally, the subjective and objective limitations of the four roles are analysed, this being based on empirical findings and the generic theory of supply chain management.

During construction, inspection, maintenance, and repair of transportation infrastructure projects, field engineers and technicians frequently refer to maps and other technical documents to check the location of structures and structural elements, and to collect data related to these structures. The concept of Mobile Augmented Reality System for Infrastructure Field Tasks (MARSIFT) will not only allow users to automatically retrieve the necessary information in real-time, based on the location and orientation of the user and within the specific task context, but it will also display this information as augmentation to the view of the surrounding real world objects such as roads, bridges, and tunnels. In this paper, the potential and limitations of the MARSIFT concept from the points of views of tracking, 3D GIS/CAD databases, and user interactions are discussed.

Construction's problems are the weakness of construction project and always being worried by the construction practitioners as it might bring failure to their project. Many have acknowledged that buildability implementation is an effective way to minimize these problems. This study focused on the buildabilty problems and its root causes that arisen in the Malaysian building construction, by conducting literature review and document study on various construction sites throughout the country. The results confirmed that there are fourteen types of buildability problems that occurred in the Malaysian building construction. Buildability problem related to utilities, right of way and drainage pattern has the highest occurrency while buildability problem related to traffic control requirement has the lowest occurency. Meanwhile, there are ten identified root causes to buildability problems with the most frequent root cause is lack of design review (C6) and the least frequent is design with time constraint (C5). This study has successfully identified the buildabilty problems and its root causes where the findings served as guide for future buildable design.

Recent research has indicated that even though construction materials and components may constitute more than fifty percent of total project costs, existing methods for managing them still depend on human skills. This traditional data collection is time and labour-intensive, error-prone, and unreliable, due to the reluctance of workforces to monitor and record the presence of large numbers of material. Automating the task of identifying and tracking construction materials can provide timely and accurate information on materials available to the manager. This paper investigates a new approach for integrating the latest innovations in ADC technologies for real-time data collection in construction. In this approach, the combination of Radio Frequency Identification (RFID), Global Positioning System (GPS), and General Packet Radio System (GPRS) technologies can facilitate extremely low-cost, infrastructure-free, and easy-to-implement solutions to uniquely identify materials, components, and equipment. The presented system is fully automatic and will lead to their location and tracking in three phases, namely, production sites (off-site), en-route (shipping), and construction job sites (on-site), almost instantaneously.
