It is a common practice in Hong Kong for the main contractors of local building projects to sublet most of the work to subcontractors. Consequently their roles have gradually transformed from a constructor to a manager of subcontractors. The outcomes of a project therefore depend heavily on the subcontractors' performance. However, most of the subcontractors complain that they are unable to efficiently and effectively operate due to site coordination problems, such as inaccurate site reference lines, caused by main contractors. The site problems may consume significant amounts of resources if practical solutions cannot be agreed by the project participants early enough. Rahim Organizational Conflict Inventory-II (ROCI-II) model was developed by M.A. Rahim that measure five types of conflict management style including Integrating, Obliging, Dominating, Avoiding and Compromising. This paper presents the questionnaire survey based on the ROCI-II model to rank the preference on the conflict management style adopted by the project representatives of the subcontractors in handling the site coordination problems and its impact to the time used to agree the solutions to the different types of site coordination problems with main contractor. The survey results show that most of the subcontractors' project representatives preferred to adopt the Compromising style to tackle the site coordination problems and the time used to agree the solutions with main contractor was influenced by the conflict management style adopted.

The objective of this study is to analyze the productivity, efficiency, and factors affecting the productivity of a spray task from an international airport project. The study is focused on the productivity analysis of the Subcontractor whose job was to supply and apply sprayed-applied fire-resistive material (SFRM) on steel members to achieve the necessary fire ratings on the building structures of the Hamad International Airport, Qatar. The study analyzed the productivity of the four sprayer teams who completed the task at three locations and three areas of the airport. The study found that the productivity of the individual team observed during the SFRM spray task was not only different but was also observed different when they worked at varying floor heights where different factors affecting productivity were predominant. The study found that the efficiency was lowest (47.32%) when the spray team had to work at second-floor heights and factors affecting productivity such as limited accessibility for material movement and lifting, site congestion, lack of continuity of operation due to priority areas and frequent re-handling of machines and tools were present. Besides, the factors such as adverse weather conditions and sub-trades interference affected productivity at all locations. The findings show that productivity depends on multiple factors and those factors need to be identified and addressed to improve productivity. The findings also show that the estimated efficiency was hard to achieve but possible since Team 4 had 97% efficiency on the first floor of the airport.

In this study, we tried to evaluate the relative importance and find out the differences in consumer perceptions regarding service recovery strategies and the service provider in the distribution industry by using AHP (Analytic Hierarchy Process) analysis method. Therefore in this study, we tried to systematize various recovery strategies which were considered very important during service failure process in the distribution industry and analyze the relative importance for each recovery strategy. We set hierarchy composed of four items of monetary, action-oriented, psychological, and assured level as primary selection criteria and a total of 16 items(indemnity, refund, gift, gift certificate, prompt resolution, exchange, manager support, explanation, apology, empathy, acknowledge, kindness, assortment, after service, manage subcontractor, manage employee) as secondary selection criteria. We tried to take one step further from the service sector and study service recovery strategies specialized in distributor services. This study suggests various implications about service recovery strategies of distributors. First, this study can provide practical implications - e.g. service recovery efforts should be applied differently depending on service channels. There is a perceptual difference with respect to the importance of the types of service recovery strategies between service provider and final customer. Second, we can find theoretical implications in terms of identifying the priorities through hierarchy design of new recovery strategies and comparison of each element from the classifications of the current fractional recovery strategies. We hope to help service providers to build more efficient recovery strategy system based on the results of this study.

Purpose - This paper is to examine the work of a third party in the process of import and export management. In other words, the purpose of this paper is investigate the status and functional role of a third party in relation to each terms of the trade contract. Research design, data, methodology - This study consists of 5 chapters through literature survey. It will examine the involvement of the third party through each terms. Chapter 1 introduction, Chapter 2 deals with trade contracts, Chapter 3 investigates the shipping terms, payment terms, and insurance terms, and Chapter 4 reviews with commercial arbitration. And in Chapter 5, it looks at the conclusion and implications. Results - The relevant party in the import and export management process may be a third party through outsourcing, not the principal. At this time, in fulfilling each condition of trade, it can be seen that the implementation of tasks through the participation of a third party with high expertise can more smoothly and productively implement the overall import and export management. Therefore, it can be seen that the implementation of the trade business in which the third party participated can be interpreted in terms of derivative effects and at the same time can be a way to improve the principal's competitiveness procedurally. Conclusions -Through this study, in the import and export management, the performance of the work through the agent makes the entire process more smooth and efficient. Outsourcing of roles using the expertise of a third party, a subcontractor rather than a principal, is desirable and important.

Consultant and owner play a very important role in the construction sector which is one of the main sectors in economic development. There are many stakeholders in a construction project including but not limited to: owner, consultant, contractor, subcontractor, and supplier. The consultant is the party who is to stay in close touch with the project owner, which both consultant and owner are considered as the main key stakeholders to make the project happen. It's not a simple task for a consultant to just implement the same style of management and control within various projects that are of a different background and character of owners. Thus, the adjusting plan management and control to the owner environment has been an essential technique to drive the project to success. The objective of this paper is to identify the significant management techniques for adjusting a plan of management and control to the owner environment in Thailand. The methodology is the identification throughout the analogous to abduction from literature review and our empirical observations of Future Engineering Consultants Co, Ltd. We have been in consultation for twenty-five years (25) in Thailand with 209 projects from both public and private owners. As a result, there are (1) Project management styles, (2) Personal style, (3) Owner expectation management, (4) Scope Management, (5) Time Management, (6) Cost Management, (7) Quality Management, and (8) Environmental Management. The input are: a clear defined goal, showing respect by giving good service, maintaining high quality, keeping in touch with owners, and resources. This would give the output of the project's success by meeting the owner's expectation and requirements.

The purpose of this study is to test the relationships between transaction justice and partnership, between transaction justice and project performance, and between partnership and project performance in the selection process in which a prime contract company chooses a subcontractor. For the empirical study, we chose a research model based on related studies and surveyed the real contractors in the field of construction. The results of this study are as follows. First, the partnership has a statistically significant positive effect on the interactional justice, procedural justice, and distributed justice. Second, the project performance is affected by the interactional justice and procedural justice. Finally, the transaction justice has a directly positive relation with the project performance and an indirectly positive relation with the project performance through partnership. In this study, we carried out empirical research into the relationship between transaction justice and project performance through partnership.

A human resource management of the general contractors is to mostly deal with daily input by each subcontractor in construction fields. However, this way has some limitations; the identification of proper human-input and productivity, preventive activities or efforts for minimizing schedule delay. The reason why these limitations are that few systematic efforts through a coordinated field administration with the construction schedule planning and human resources. Therefore, on the basis of the construction schedule planning, human resource management of subcontractors is necessary to make for an improvement in construction schedule control. Daily Scheduling Check System(DSCS), as the linked human resources on an existed CPM scheduling software, was developed and this paper then verified validity and effectiveness of using the DSCS for the framework of some actual apartment construction projects

Objectives: We investigated the status of accidents and deaths caused by chemical leakage and skin contact in Korea. The purpose of this study was to produce and provide technical reference data for the efficient management of accidents and the rational management of accidental chemicals. Methods: Accidents and deaths caused by chemical leakage and skin contact in industry were investigated. Based on 68 accident reports related to chemical leakage and skin contact, the causes of accidental deaths were analyzed. In addition, we investigated the chemical substances and articles that caused these accidents and deaths. Based on the results of the investigation, the causes of accidents caused by chemical leakage and skin contact were identified and practical management measures for the chemicals were suggested. Results and Conclusions: In 2018, 372 people suffered from chemical leaks and skin contact, up by 123 (about 49.4%) from the previous year. The number of accident deaths was 14, an increase of five (about 55.6%) from the previous year. In the last three years (2016-2018), 91 chemical substances and article groups were involved in accidents caused by chemical leakage and skin contact. There were 16 chemical substance and article groups involved in accidental deaths. There were ten cases of accidents involving two or more casualties due to chemical leakage and skin contact, and 23 deaths occurred. Most of these accidental deaths were caused by subcontractor workers outsourcing risks. Therefore, there is an apparent need to strengthen the responsibility for safety and health among subcontractors.

Although reinforcement of work intensity caused by the recent prosperity of shipbuilding businesses and the steady increasing of results which produces orders has difficulties with heavy workload, unique work circumstance in shipbuilding industry where main and subcontractor do the job together is not easy to manage its safety systematically. According to KOSHA(Korea Occupational Safety & Health Agency), there were 2, 587 deaths of 95,806 disaster victims a year on average for late 6 years(2003-2008), therein 36,605 disaster victims and 646 death in manufacture where shipbuilding have 2,287 victims, 6.25% of total disaster victims and 45 deaths, 6.97%. Moreover it shows much higher accident rate in shipbuilding industry in Korea than well developed countries in this industry as Japan, Singapore, Taiwan and so it does about 3 to 10 times higher in case of death. Compared to Japan with a shipbuilding competition of orders received system, 2 times and 2.3 times higher for each and it is more than 2 times higher than accident rate of all domestic industries. These increasing of disaster result in a labor-management dispute and it is necessary that more positive efforts and investments because there occurs blind spot, neglected industry safety and health management by lack of them, Therefore this study, for the effective safety and health management of shipbuilding industry, attempts to analyze risk on kinds of ships and budget needed in safety management through classifying ships that are being made recently by three dominate major companies. For this, we carried out a survey and interview targeting experts related to shipbuilding industry and used AHP(Analytic Hierarchy Process) for result analysis. It is considered that cost of safety and health management will be spent more effectively on the results about risk on kinds of ships and budget needed in safety management in the study and that this study can contribute to decreasing disasters in shipbuilding industry.
