Facing the rapid changes in business environment, construction companies have been required to improve their structures to reinforce the competitiveness. Construction companies have attempted the various management innovation and taken measures to enhance the productivity through the information systems. But compared to the efforts made in restructuring and process improvement, organization issues have not been considered sufficiently. So this study was executed to discuss the organization changes due to the innovation occurring in construction organization. This study was focused on the organization controlling the activities directly in construction site and the work process improvement in management.

The adoption of Environmental, Social, and Governance(ESG) practices in domestic construction firms is predominantly driven by major corporations. These companies not only publish reports on their ESG management but also engage in a meticulous process of identifying key issues and setting priorities. This process entails an in-depth evaluation of the severity of various issues and the gathering of insights from experts in the field. Interestingly, a comparative analysis of ESG assessments for construction companies, both domestically and internationally, reveals significant discrepancies in outcomes. These differences stem from the varied evaluation methodologies and criteria employed by different assessing bodies. Addressing this gap, our study proposes a suite of strategies aimed at bolstering ESG management within the construction sector. We advocate for enhanced policy support and financial backing, especially targeting small and medium-sized enterprises(SMEs) to facilitate their engagement in ESG practices. A critical step forward involves the standardization and transparent disclosure of ESG evaluation criteria, tailored to reflect the unique aspects of the construction industry. Moreover, the standardization and publication of ESG assessments for subcontractors are essential, equipping them with the necessary tools for effective ESG management and evaluation. Given the global nature of construction projects, particularly those commissioned by the European Union in regions like Africa and East Asia, adherence to ESG standards is imperative. Our long-term vision includes the development of a comprehensive database detailing ESG regulations and their impacts, segmented by region and country. This repository will serve as a valuable resource for companies venturing into international construction projects.

The domestic construction market started to expand steadily since 1970s. The building market which utilizes a sandwich panel with advantages of economical construction expenses and convenient construction has grown rapidly in recent years. However, the companies which specialize in constructing sandwich panels are relatively small or medium size, compared with other construction companies. As a result, studies on the improvement of productivity have not been conducted sufficiently. In this study, the construction sites of sandwich panel are investigated, and the work processes by each team are analyzed. Additionally, the productivity and the construction cost of each construction team are analyzed by constructing a model using the Web-Cyclone. It is expected that the results of this study can be applied to estimate the productivity and the construction cost of a sandwich panel construction that is appropriate for the on-site characteristics of small and medium sized construction companies in Korea. Also, similar processes can be simulated based on the modeling constructed in this study.

In building information model (BIM), it is difficult to train an artificial intelligence (AI) model due to the lack of sufficient data about individual projects in an architecture firm. In this paper, we present a methodology to correctly train an AI neural network model based on a large language model (LLM) to predict the steel structure product weight ratios in BIM. The proposed method, with the aid of the LLM, can overcome the inherent problem of limited data availability in BIM and handle a combination of natural language and numerical data. The experimental results showed that the proposed method demonstrated significantly higher accuracy than methods based on a smaller language model. The potential for effectively applying large language models in BIM is confirmed, leading to expectations of preventing building accidents and efficiently managing construction costs.

Using PMIS(Project Management Information System) plays an important role in systematically planning and effectively managing the complex and large-sized construction projects. In spite of the importance of PMIS, on-site engineers, who are the main users of PMIS, have not used PMIS enthusiastically because PMIS has been evaluated and improved by not the viewpoint of the system users but the viewpoint of system managers and head office manager. Therefore, this study developed an assessment model to evaluate PMIS with the viewpoint of the on-site engineers, so previously developed PMIS can be evaluated by the on-site engineers with importance and satisfaction elements. It is anticipated that the effective use of the developed assessment model might increase the utilization of existing PMIS as well as develop the construction industry.

In recent years, large Korean construction companies have suffered serious losses in their overseas business. Many practitioners and researchers have analyzed causes of cost overrun in these projects. However, these arguments have not been empirically verified based on acutal project cases. This study investigated cost overrun rate, contingency, allowance, predicted risk before bidding, and actual and residual risk after award in the 67 international infrastructure projects conducted by 13 large construction companies. The causes of cost overruns are derived as follows. First, they identified the possibility of cost overrun to some extent before the bidding, but did not reflect the enough risk money to bid price. In particular, this behavior was more severe in badly cost-overrun projects. Second, the causes of cost overrun were more influenced by external environmental risk than internal capability risk. However, the internal risk in badly cost-overrun projects was relatively high compared to cost-underrun projects. Third, badly cost-overrun projects failed to mitigate risk. However, cost underrun projects were affected more by low exterior risk conditions than by well mitigated risk. This study provides more informed knowledge in controlling project costs in international infrastructure projects.

This study analyzed the impact of changes in the construction business on construction company insolvency according to their size using the vector error correction model. First, this study applied EDF (Expected Default Frequency), which was calculated by KMV (Kealhofer, McQuown and Vasicek) model, as a variable to indicate the insolvency of construction companies. This study set 30 construction companies listed to KOSPI/KOSDAQ for estimating the EDF by size and construction companies were divided into two groups according to their size. To examine the construction business cycles, the amount of construction orders according to the type-residential, non-residential, and civil work- was used as a variable. The serial data was retrieved from TS2000 established by the Korea Listed Companies Association (KLCA), Statistics Korea. The analysis period was between the second quarter of 2001 and fourth quarter of 2015. As a result of calculating the EDF of construction companies by size, as it is generally known, the large-sized construction companies showed lower levels of insolvency than relatively smaller-sized construction companies. On the other hand, impulse response analysis based on VECM confirmed that the level of insolvency of large-scaled companies is more sensitive to business fluctuations than relatively smaller-sized construction companies, particularly changes in the residential construction market. Hence it is a major factor affecting the changes in insolvency of large-sized construction companies.

The purpose of this study is to clearly recognize critical issues and to suggest relevant solutions for the issues since too many deaths and injuries due to industrial accidents has been going on for a long time, also the deaths of workers is a problem that affects not only one person's death but also many people connected with it and society as a whole. And the need for a strict Serious Accidents Punishment Act is sympathetic. However, the current Severe Accident Punishment Act is not welcomed by both labor and management due to its ambiguity, and it is suggested that the punishment and legislative content of the management manager who violated the duty to ensure safety and health is abstract and the level of punishment is excessive. In addition, due to the ambiguous part of the management manager's interpretation and serious industrial accidents, most companies appoint large law firms to receive legal interpretation and advice, so only law firms are getting full, and the cost that companies invest to protect the CEO is actually a safety accident. It is suggested that the current enforcement ordinance, which has ambiguity, needs to be revised because it must be entered into as a preventive cost.
