  • After the 2008 global financial crisis, the construction environment in South Korea continued change in the construction environment. Construction orders in 2011 have shown a downward trend compared with the previous year. Along with these changes in the construction market, the professional capabilities of construction project managers that are perceived as important also changed after the global financial crisis. Accordingly, this study was conducted to identify the major business capabilities of the current construction project managers and to determine which of these capabilities have undergone changes in terms of the importance accorded to them after the global financial crisis, and ultimately, to derive the construction project manager capability areas that need to be strengthened according to the changes in the construction environment. The capabilities of construction project managers were surveyed at two different time points: in 2007 and in 2010. The results show that the year 2010, after the global financial crisis, an increase in the perceived important capabilities of construction project managers compared with 2007. This results the impact of the changes in the construction environment on the importance of construction project managers. This study derived the ramifications of the early identification of systems and prospects according to the changes in the construction circumstances on more efficient onsite and human resources management, by considering the appropriate capabilities of the construction project managers.

  • Construction Cycle Trend Survey, which survey total value of orders and realized amounts monthly, is a valuable statistics that used to quick grasp or forecast the trend of domestic construction business. In recent periodical survey quality diagnoses, few professional users named a problem that Construction Cycle Trend Survey could not get together with the current state of the construction industry. This study examined weather Construction Cycle Trend Survey reflects the economic sentiment of construction business or not. Paired t test was performed between Construction Cycle Trend Survey and Construction Business Survey Index (CBSI), and significant differences were verified.

  • Although the importance of the construction lift is increasing, no improvements are being made to its operating system. This study proposed an optimal call-response algorithm of the construction lift for high-rise building construction by using image sensing technology, height measuring sensor, and load cell. This algorithm makes turn-around decision of the construction lift by considering the information and the number of user. It occurs when the call comes from a floor where the construction lift already have passed. The purpose of this study is to reduce the total latency of the construction lift user. Furthermore, it is possible to prevent delay in construction duration by carrying out a priority operation of the construction lift for the critical workforce.

  • As the construction industry has been increasingly complex, aging workers, hard-working avoiding young generation, foreign workers having language problem for the past decades, delivering of construction qualified workers has been a rising problem. This misalignment between the complex jobs and the number of skilled workers will continue to be in issue that the construction industry will face for following decades. Construction field workers who are working outside in uncontrollable condition unlike manufacturing industry are exposed to easily construction safety accident. There are so many efforts to prevent and control the construction accident. However, the relationships between the construction works and construction safety accident has not been well dealt and investigated based on objective accident data except for the qualitative study through interview, delphi and so on. Therefore this study analyzes job risk matrix exposed to safety accidents based on statistic data for 20 years from Korean Occupational Safety & Health Agency in order to prevent the construction field accidents.

  • This study was conducted to present the improvement in professional perception among construction workers engaged in domestic construction sites by analyzing the reality of their professional perception. The results are as follows: First, with regard to professional perception of the construction industry, managerial workers made their positive reply to items regarding construction and construction workers but had their negative attitude towards construction as a job and as a recommendable job for others; whereas production workers showed their negative reply to all the items. Second, with respect to factors for construction being firmly regarded as an 3D industry, managerial workers selected 'long working hours' and production workers replied with 'low wages and income insecurity.' Third, as for improvement activities for professional perception of construction, most of construction workers simply knew about activities being performed but expressed their intention to participate in the activities.

  • With the social demands for tall building, the level of techniques for construction become high and there are various building materials. Also, the construction system become very complicated with the increase of worker. In spite of above facts, the method of construction management depends on the experimental capacity of a construction manager, and there are many unreasonable elements. These elements prevent well-going in construction process. To solve this problem, it is necessary to make a new system of construction management which is adequate for the condition of company and the contents of construction. In this study, the characteristic of production system and the present condition of construction management were investigated with the help of survey. Thus, the new method of construction management which can clear the previous problems was proposed.

  • Accompanied by Chinese strong economic growth rates and development of demand for the construction industry, Chinese construction industry has already become one of the largest construction markets in the world. Unfortunately, the frequent occurrence of safety incidents on Chinese construction sites is a large obstacle for other countries construction companies seeking to enter the Chinese construction market. This study aims to analyze and compare the safety awareness of Chinese and Korean construction workers. Our research showed that the safety awareness of Korean construction workers is far higher than that of their Chinese counterparts, particularly in terms of the efficiency of safety education and the observance of safety rules. The development of a safety management plan based on these results will contribute to reducing the frequency of accidents on Chinese construction sites.

  • In this paper, a survey related to excavation construction activities among national and international construction companies was conducted to evaluate site productivity in construction industry. To analyze the respective productivity levels of each construction company, a benchmarking measures analysis that featured calculations of the performance ratio (PR) and performance management index (PMI) was performed. As a result of these analyses, it has been found that the work performed by local companies was marked by lower productivity and that of international companies was characterized by good productivity. Further analysis of construction workforce resources P% revealed that a construction company's productivity is largely dependent on production capacity and consumption resources, which means that the retention of skilled workers and utilization of high-quality resources yields the highest level of productivity. These results suggest that for a local construction company to be competitive in the construction work market, it must retrain skilled craftspeople, foremen, engineers, and project managers, and strengthen its building capability by leveraging new equipment and technologies.
