Construction safety education will continue to attract the interests of construction educators, researchers, and industry professionals due to its immense influence on accident reduction and prevention. A well-educated workforce with a thorough understanding of safety requirements and procedures is needed to develop and apply effective safety and health programs as well as devise strategic means of preventing injuries, illnesses, and fatalities on construction projects. The objective of this research is to evaluate construction safety education in the curriculum of construction programs in the United States. An analysis of construction safety courses across accredited construction programs in the U.S. is conducted to synthesize important details and common themes. A nationwide characterization of the safety courses presented followed by an assessment selected a few programs as a pilot study. Critical elements of the courses such as course titles, course year, credit hours, topics covered, and alignment with professional certification or outreach training courses are characterized. Findings from the study reveal the similarities and variations that exist among safety courses taught in different construction programs in the U.S. These findings could result from several influencing factors, which could be the subject of further investigations geared toward improving safety education in construction programs.

This research executed research that analyze construction cost and profitability through construction example of direction and subcontracting construction based on common private construction less than 3 billion. The results of this research, is summarized as follows. (1) Analyzed profitability about construction gross and operating profit of direction and subcontracting construction. The construction gross profit rate is 15.2% direction construction, subcontracting construction was analyzed by 1.3% high by 16.5% subcontracting construction, and the operating profit rate is 9.4% direction construction, subcontracting construction was construed by 2.3% high by 11.7% subcontracting construction. (2) Analyzed profitability about operating profit before and after deduction of 4 insurance cost of direction construction. The direction construction operating profit rate is 9.4% before deduction of 4 insurance cost, after deduction was construed that is 7.3% and operating profit rate difference after and before deduction was construed that is 2.1%. Therefore, subcontracting construction (operating profit rate 11.7%) was analyzed that last operating profitability after 4 insurance cost deduction produces more 4.4% about direction construction.

According to the recent systemic changes such as construction market reduction, five days per week system, introduction of construction duration reduction bidding system and post-construction sale system, the bidding competition have been enhanced. However, there are many construction schedule risks which could delay construction completion. Without the proper identification of construction schedule risks and the structured construction schedule risk management, the competitive advantages of construction project could not be made. Previous researches to solve the problem have been focused on the construction schedule categorization, construction schedule management, and the system development to manage the construction schedule risk. Therefore, this study selected the reinforeced concrete construction as the studied work due to the major impact characteristics on the total construction duration and the quite accident rate, and then proposed the real construction schedule risks of reinforced concrete construction and the construction risk management method based on the previous studies, many times of expert interviews and brainstorming.

This paper presents a fundamental study to establish a standardization system of the Construction Continuous Acquisition and Life-cycle Support(CALS). A state of the art in standardization of the Construction CALS is reviewed to find some defects in developing CALS system in construction industry. It is analyzed that three major parts were needed to set up a standardization system for the Construction CALS. Firstly, the range of Construction CALS standardization is set up to identifying Construction CALS and defining the standards and standardization. Secondly, the strategy to carry out more effectively in Construction CALS standardization and make the relationship of the concerned system presented here can be used to establish the Construction CALS standardization system. In addition, the spread and application device are proposed to use Construction CALS standards at public institution and construction related companies. Conclusively, a classification of the Construction CALS standards was proposed and some objects to be standardized were represented in that. Results studied in this paper will provide the primary information and basic model to develop a guideline for standardization of the Construction CALS.

The drawing information takes the most essential part of construction information. The management of construction information through drawing information facilitates input, output and search process, thus helping maximize the usage of construction information by effectively sharing construction experience and drawing information. This paper shows how construction information can effectively used to increase the productivity of the construction process as a whole. Construction information was extracted and classified by the elements of building which are the basic and very end components of building, to accumulate information of each construction phase. Based on the result, the Element Breakdown Structure(EBS) was developed for the practical usage of construction information integration.

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.

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.
