In recent years, the Japanese government is paying attention to utilizing foreign workers. As a measure for this, the utilization of persons who completed practical training in the Technical Intern Training Program (TITP) in the construction industry and expansion the period and number of recipients of the TITP. These are clearly securing the labor force. However, the acceptance policy is currently "skill training”. In this paper, field survey on building production system in Singapore implemented three times from FY 2014 to FY 2016 summarized the introduction process and actual circumstances of various systems related to foreign workers in Singapore. Also, by organizing the its framework, we will grasp actual conditions and issues. I believe that this paper can contribute as reference material when considering the foreign worker acceptance system in Japan. Foreign workers working in Singapore have changed from Malaysia and China, through Thailand and India to Bangladesh and Myanmar. Naturally, if own country becomes rich, you do not have to go abroad to work. Therefore, there is no compensation for Singapore to keep foreign workers for everlasting. From this influence, it is thought that emphasis is placed on policies for restraining foreign workers and productivity improvement in recent years. In recent years, attention has been focused on utilization of foreign workers. From this situation, it will become a future issue for Japan that build an international strategy to win the competition for securing human resources with neighboring foreign countries. The following is a summary of a part of Singapore's policies and institutions considered to be helpful. ·About dual policy with productivity improvement As a countermeasure against the labor shortage of their citizens, system design that integrates foreign workers' utilization measures and productivity improvement will be helpful. In particular, measures to alleviate the stay conditions of workers who acquired skills can be evaluated as measures that are beneficial to both workers and employers. ·About the system for skill improvement It is characterized by the establishment of a skill development system within the wage system guaranteed by the government. For example, it is a practical exam before entering the country which is a condition of WP, promotion to MYE or R1, etc. Since many of the foreign workers in the construction industry belong to subcontractor companies enterprises of a small-scale, it can interpret that the social development framework and the support of the former contractor business are operated in the system.

Building information modeling (BIM) is an important technology in the design and construction of buildings. BIM is also used in the construction of building equipment. In recent years, construction companies have been promoting the introduction of BIM. Typically, the technologies of building construction are introduced for each department. However, BIM has been promoting technology introduction beyond departments and companies. Therefore, we analyzed the process of introducing BIM in construction companies. We also analyzed the proportion of companies that introduced BIM, process of technology introduction, and the organizational form of the construction companies. In this study, we conducted a questionnaire survey of construction companies about BIM. Based on the questionnaire results, we performed an analysis of corporate organization as follows. 1. Analyze the relationship between the respondents of a department and technician experts by cross tabulation. 2. Classify respondents by factor analysis. 3. Discuss the motivation behind introducing BIM by covariance structure analysis. The percentage of companies that have used BIM in their construction projects was approximately 32%. Moreover, 40% of the survey respondents collect BIM information. More than 50% of the respondents think that construction work using BIM is more efficient than the traditional construction work. These results mean that BIM entered a stage of popularity. On the other hand, the percentage of engineers that manipulate 3D-CAD or BIM is only approximately 23%. The occupation of the highest percentage of 3D-CAD users is construction engineers of building equipment. Architects are also a high percentage of 3D-CAD users. Then, we created a contingency table (Table 4) for the relationship between the current department and the specialized field of survey respondents. All personnel who belong to the building construction department are part of the specialized field of building construction. On the other hand, 22% of the personnel who belong to the architectural design department are part of a different specialized field of architectural design. Next, we performed an exploratory factor analysis on the questionnaire results. Maximum likelihood estimation with a promax rotation of 32 Likert scale questions was conducted on data gathered from 212 participants. The results of the promax rotation of the solution are listed in Table 8. When loadings less than 0.35 were excluded, the analysis yielded a seven-factor solution. The seven factors were labeled as follows: "Expectations of BIM (Factor 1)", "The degree of information gathering about BIM (Factor 2)", "The need for the introduction of front-loading (Factor 3)", "IT skill levels of the respondents (Factor 4)", “Adequacy of information equipment in the belonging company (Factor 5)”, “Growth potential of the construction industry (Factor 6)”, and “Dissatisfaction with the current construction technology (Factor 7).” Moreover, we performed a hierarchical cluster analysis by selecting three factors—Factor 2, Factor 4, and Factor 6. As a result, we classified four respondent groups. In addition, we analyzed of the motivation behind the introduction of BIM by structural equation modeling (SEM). The results of SEM analysis are shown in Fig. 12. SEM supposes that motivations behind introducing BIM are to improve productivity of the construction work.

The interior finish work of apartment building does not progress on schedule in Japan though the apartment construction does. Japanese general constructors have challenged to this issue since the 1970s, but there is no example established as a standard method for interior finish work management.We investigated the process of the interior finish work and analyzed the obtained data, which revealed that the problems were in the relation of product structure, scheduling and work assignment.
