The recent fourth industrial revolution and the era of post-COVID-19 have ushered in a series of technologies including a 5G network and online systems, such as cloud computing technology. In other industries, extensive studies on cloud platforms utilizing such technologies were conducted. Although the cloud environment has taken on greater importance in the construction sector as well, it was used only for servers, failing to fully reflect the characteristics of the cloud system. In particular, compared to large architectural design firms, it is challenging for small to medium-sized design firms to establish a virtual cloud computing environment, which requires high capital investment. Targeting small to medium-sized architectural design firms in Korea, this study was conducted to introduce the VDI system, one of the cloud computing technologies that was recently used in other industries, to the BIM environment for initial application, operation, and management. Specifically, after an analysis was carried out to see if the VDI system utilized in other industries may resolve the hindrance faced with the BIM environment in the construction industry, the KBimVdi system was created based on an algorithm for estimating server scales by analyzing the VDI system suitable for the BIM work environment. This was followed by a validation of the KBimVdi system based on selected projects carried out by small to medium-sized architectural firms where BIM was used for design work.

While industrial plant projects are becoming bigger, and global attention to the plant as a construct is increasing, space arrangement in plant projects is inefficient because of the complex structure of required facilities (e.g., complex MEP (mechanical, electrical, and plumbing) installations, specialized tools, etc.,). Furthermore, problems during installation, operation, and maintenance stages caused by inconsistencies between floor plans and actual layout are on the rise. Although some of these conflicts can be addressed through clash detection using BIM (building information modeling), quality BIM models are scarce, especially for existing industrial plants. This study proposes a way to address the complexities caused by changes during plant construction and securing space for the installation of equipment during the construction and lifecycle of built facilities. 3D cloud point data of space and equipment were collected using 3D laser scanning to conduct space matching. In processing the space matching, data were simplified by applying the 3D grid and by comparing the data, easier identification of the space for target equipment was accomplished. This study also proposed a pre-processing method based on sub-sampling that optimizes the point cloud data and verifies the processing speed and accuracy. Lastly, it finds free space for various equipment layouts required in industrial plant projects by space analysis, proposed algorithms, and processes for obtaining the coordinates of valid space for equipment arrangement. The proposed method of this study is expected to help solve the problems derived from arrangement and installation of new equipment in a complex plant site.

The more detailed building information modeling (BIM) is, the more accurate are the quantities that can be extracted in BIM-based quantity take-off. However, the time and cost typically allowed for modeling are insufficient to extract accurate quantities throughout a project’s life cycle. In addition, variations in quantity interfere with estimating accurate construction costs. Despite the recognition that extracted quantities can differ depending on the details of building interior components, the number and extent of discrepancies, or whether these would differ by material, is unknown. Therefore, this study identifies and analyzes the approximately 6–9% quantity discrepancy (QD) in quantities extracted from different building interior components, in order to improve the accuracy of cost estimation using BIM. The discrepancy was analyzed by comparing the extracted quantities via two different model types, specifically a compositely modeled object and an individually modeled object. These models were applied to four cases of interior work in residential units. Results indicate that the QD occurs non-sequentially and exceeds the loss rates for some interior materials. Furthermore, this study identifies the causative factors of the QD by common features observed in the particular materials and suggests modeling and measurement strategies for minimizing QD.

Inaccurate information regarding the terrain in construction projects represents a major challenge to the earthwork process. Both construction quality and productivity have to be addressed by means of efficient construction information management in large earthwork projects in order to ultimately improve the cost-effectiveness of such projects. Research into the technologies for creating precise three-dimensional data and maps of earthwork sites is progressing steadily. These technologies aim to make it possible to conduct unmanned operations, leading to the effective management of earth working equipment. In recent years, as the importance of three-dimensional (3D) shape information management has grown in the construction industry, the research and application of 3D point cloud acquisition methods has likewise increased. The current method for acquiring point cloud data through laser scanning renders it difficult to acquire point clouds in large construction projects, especially in earthwork projects, due to the topographic conditions of the site as well as the physical and material limitations of the laser scanning equipment. In order to overcome and compensate for the limitations of laser scanning, image-processing technology involving unmanned aerial vehicles (UAVs) has been used to acquire point cloud data, although its application has been limited due to its low accuracy. Therefore, this study proposed a method for generating and merging hybrid point cloud data acquired from laser scanning and UAV-based image processing. In addition, a comparison was conducted between the datasets acquired from laser scanning and image processing, using examples from some case studies. Finally, an analytical comparison was performed to verify the accuracy of the UAV-based image processing technology for earthwork projects.

As the height and size of urban buildings constructed in cities in Korea have recently increased, vertical lift planning and operation is a key factor for the successful project of a tall building. Although many studies have attempted to set up a lift planning system at an early stage, a real-time lift operation control system with respect to the construction stage has yet to be proposed. Therefore, in this study, the sensor module and storage device named the Embedded Lift Information System (ELIS) was used to collect the lift operating data for improvement of lift operation efficiency in order to develop an optimum lift operating analysis system which could perform real-time analysis. Finally, the pattern of operation data of the lift was analyzed and the lift event of the next day was derived. In addition, we verified the efficiency of the proposed optimum vertical zoning simulation system using the expected lift event extracted from the operation history data pattern. In this paper, the proposed system provides more efficient vertical zoning alternatives for the lift manager. This simulation based decision making tool reduces the user's queuing time compared with the previous system. This system is expected to contribute to high-rise building construction of over 400 m.

The domestic plant construction market is in a prosperous condition, due to the uprising demand for industry facility and infrastructure, triggered by the oil price rise in Middle East Asia. It is difficult, however, to survive in competition with advanced foreign construction companies, because domestic companies rely heavily on labor-intensive construction conventions in AEC(Architectural, Engineering and Construction industry). In particular, the piping work in a plant construction project accounts for many portions of the critical paths, from the viewpoint of process control. Although plant construction projects need to deal with complex three-dimensional piping information, most domestic companies rely on two-dimensional CAD drawings for construction and quality control, which frequently leads to significant problems, such as construction delay, and productivity decrease. For such reasons, it is problematic, in that the build ability, workability, and productivity of projects are dependent on the workers’ abilities to understand drawings and their technical skill. In other words, as plant construction projects are getting more complicated in details, and more increased in size, it is urgently needed to develop an efficient information management methodology, in order to figure out heterogeneous 3D piping information in a real-time manner. Reverse engineering for obtaining 3D shape information using a 3D laser scanner is used, in order to extract drawing information from constructed objects. In particular, as piping works control the Critical Path (CP) in the plant construction project, in this study, a reverse engineering algorithm is proposed, which can measure the preciseness of pipes, by comparing the 3D CAD model and the 3D shape information obtained from a laser scanner. Applying the algorithm can contribute to re-construction prevention and quality control in the construction process.

The technology to automatically detect the surrounding working environment for modeling of the result is the key essential technique for the automation of the construction equipment developments. When noise takes place during 3D modeling of the front work area of the automated construction equipments, the point of noise occurrence during the surface modeling can result in ground level phenomenon in the form of triangular pyramid to lower the quality of the modeling. This can greatly affect the detection of the objects around the automated equipment. This study proposed revised object clustering and differential algorithms for noise elimination of 3D terrain model and compared the noise elimination performance of existing algorithm and proposed algorithm on the images of actual earthwork working environment. It is expected that the noise elimination algorithm proposed in this study will be very useful as a widely used essential technology required for the development of automated technology not only in earthwork field but also in other general construction and civil engineering fields by noise elimination of the 3D working environment model.

The authors have developed a tiny, low-cost accelerometer that utilizesa semiconductor fabrication technology called MEMS (Micro Electro-mechanical System), for building a sensor network which would have a large quantity of such sensors deployed all over the host structure to be monitored. Due to the small dimension and extremely low power consumption, the sensor device is well-suited for such networks, where the supply of external power is very constrained. The authors have designed both a sensor device, and a sensor module having wireless communication capability built around it, and tested them in real-world tunnels, as well as in test labs. The test results showed that our prototype performed adequately for its intended use.

To the construction industry that had recently suffered from a depressed domestic construction economy, the overseas construction market offers a foothold to overcome the limitations of the domestic market. In order to promote the continuous growth and development of overseas construction exports, Korean construction companies need to secure overseas market information, and to be strongly competitive. However the Korean construction industry has weaknesses in its ability to obtain information and experience, which are the most important factors in entering the overseas construction market. Therefore, this study aims to suggest business entry road maps by business types, in order to enter the Vietnamese construction market, which presents abundant development potential. To measure the Vietnamese construction market, a market entry evaluation model, which integrates the evaluation scores of marketability and competitiveness, was utilized to analyze the market entry potential by project types. According to the analysis results, general building projects and infrastructure projects in Vietnam in the long term are projected to expand from the currently dominant private investment projects, to a larger scope, along with the increase of public investments. In particular, as for public investments in the general building field, market entries will be smoother in the form of Public-Private Partnership.

For plant construction, installation of complex pipe spools is one of the integral parts of management and operation. Construction errors in such plants have been increasing as they become bigger and more complex. To reduce the number of construction errors, an efficient management mechanism for pipe spool installation with real-time monitoring is desired. A Ubiquitous Sensor Network (USN), which utilizes low-power wireless data communication technologies such as Wireless Local-Area Networking (WLAN) and RFID (Radio Frequency Identification) is seen as an enabling technology for intelligent management of piping installation. This research aims to develop a real-time pipe tracking system for plant construction, utilizing state-of-the-art technologies such as RFID and 3D digital models on a handheld mobile device, which allows more efficient task management than a conventional computer.

This paper reports smart wireless sensor node for Structural Health Monitoring (SHM) that is capable of operation with energy harvesting systems using piezoelectric materials. A large amount of research has focused on utilizing the impedance method for structural health monitoring but these studies required expensive and bulky impedance analyzers, which are unsuitable for field deployment. Piezoelectric materials can be used as mechanisms to transfer ambient vibrations into electrical energy that can be stored and used to power other devices. In this study, three types of piezoelectric materials were evaluated experimentally for use as power harvesting devices. In general, the power produced by the vibrations of piezoelectric devices is low, meaning that the equipment powered by the device cannot be operated effectively. Therefore, a time delay circuit and reset IC chip was used to improve the efficiency of the electrical power generated. The experimental results were used to estimate the efficiency of these devices and identified the feasibility of their use in practical applications.

High-rise construction sites, especially those situated in spatially-constrained urban areas, have difficulties in timely delivery of materials. IT-driven management techniques can be further benefited from state-of-the-art devices such as Radio Frequency Identification (RFID) tags and Ubiquitous Sensor Networks (USN), which have resulted in notable achievements in automated logistics management at the construction sites. Based on those achievements, this research develops USN hardware toolkits for hoists, which aims to automate the vertical material delivery by sensing the material information and routing it automatically to the right place. The gathered information from the sensors can also be used for monitoring the overall status. To support the system, a hoist-mountable intelligent toolkit was developed. Its feasibility test was conducted by applying the implemented system to a test bed and then analyzing efficiency of the system and the toolkit.

Various attempts have been made to apply Radio Frequency IDentification (RFID) technologies to current construction operations and processes; however, RFID applications have still required considerable investments and efforts to be successfully applied in the real construction projects. This paper examines the RFID technology applied to construction projects. A simulation model is developed to quantitatively evaluate the possible productivity benefits of RFID in construction. The model is based on the case study of a real construction project where the critical points of economically feasible solution for RFID application can be searched variable depending on the costs of RFID tags and RFID readers The simulation model also compares performances to apply RFID applications before and after. The results of simulation showed that RFID technology is effective for enhancing the project performances improvement at the operation and process level by reducing cycle time, decreasing queuing time, and improving other benefits including reliability of construction operations compared to invested costs. The results, however, also indicated that RFID application needs for further analysis in view of assessing qualitative aspects as well as implementation obstacles, based on more broaden case studies.
