According to the preceding research outcomes, feasibility studies on public construction projects were incorrect and subjective. To resolve the problems, Korean government initiated Preliminary Feasibility Study (PFS) system prior to undertaking the main feasibility study. The PSF can be categorized into four areas such as road, railroad, harbor, airport, and Culture & Tourism (C&T). Especially when it comes to complex due to the introduction of five-weekday working system and local $government^{\circ}{\phi}s$ self administrative system. As a result, the standardization and legislation of the PSF can not be operated effectively. Accordingly this paper seeks to 1) identify actual condition of conducted PSF in C&T; 2) set up analytical model considering cost factor of economical efficiency and seek obstacles of PSF system; 3) suggest improvement plan for construction PSF projects.

Despite the trend of decreasing accidents, falling accidents in the construction industry have not decreased and are even rising. Most major accidents are falling accidents caused by hanging scaffolding and are mostly serious. We conducted a review of the literature, institutions, and regulations, which showed that domestic standards are not unified because they are drawn up by referring to overseas standards for hanging scaffolding. New regulations or standards should be established, which should reflect the safety plans for equipment, work advance plans, education, and management. If facility improvement plan for Hanging Scaffolding and implementation of revision of the current work use, regulations and guides are implemented, it will be recognized in advance of the causes of the accident statistics and the classification system and will be the basis for the implementation of joint efforts by workers, managers, supervisors and owners to reduce accidents.

The purposes of this research are to examine soil pollution in the nation and to explore the contaminated soil management of the public housing agency in public land for residential development. In so doing, the primary and secondary data were utilized, the former made use of the public data annually released by the Korea Ministry of Environment, and the latter relied on a self-administerd questionnaire survey conducted in the staff of the public housing agency, particularly those in charge of soil contamination in large-scale land, housing and urban development projects. The findings reveal that the national concentrations of 21 inorganic and organic soil contaminants (e.g., Cd, Cu, As, Hg, Pb, Cr, Zn, Ni, F, P, PCB, CN, Phenol, BTEX, TPH, TCE, PCE, Benzo(a)pyrene, and pH) in the land were extracted to be well below the risk level designated by the statutory guidance while industrial areas had them at a relatively modest level. In addition, the survey results indicate that the public housing agency didn't establish specific and clear guidelines for soil pollution and its remediation in the residential land development, so that contaminated sites have been primarily remediated by outsourcing companies. As the unexpected occurrence of contaminated sites causes the incurring expenses added to total project budget, the provision of both professional training and on-site manuals with the sufficient information on techniques and methods of soil contamination is critical to promptly and systematically deal with soil pollution.

The trends of Green growth and environmentally-friendliness came to be the key development indicator for sustaining global environment for the future. Korean government reflected these trends in the main flows of the national development index. Korean construction industry is concentrating investment on fields related to these trends such as technologies for carbon dioxide deduction, materials or products for environmentally-friendly building and alternative energy development, as well. However, efforts to follow these trends during the construction process as a step for production phrase are not being considered enough. In this study, we analysed current status and points to be improved of on-site environment management by surveying major project owners and representatives of the environmental affairs in the leading companies of those fields. Also, we suggested organizational structure and operation model as a solution for enhancing environmentally-friendliness for systematic approach to manage on-site environment in public construction sites. In addition to these solutions, further approaches such as shifting paradigm of project owners and contractors, securing workforce and practical budget for efficient management activities, developing environmental management manuals, setting standards for evaluation of activities are needed for the stable settlement of on-site environmental management.

Today, current society is unceasingly changing. This phenomenon accelerate building to high-rise and complex. According to that, to build a construction structure, the safety management facilities, safety education & training for employee and consciousness for safety should be set aside. But, the occurrence of safety injury is not decreasing now. Therefore, to reduce safety injury and to enhance the consciousness of employee for safety, redesign of safety management system, reallocation of safety liability for privity, revise of safety educational system were suggested in this paper.

Total Project Cost Management System(TPCMS) was introduced with the purpose of increasing the efficiency of cost control for public construction project in 1994. In this paper, general perception of participants of the public construction project on the TPCMS was examined, and the problems in implementing the TPCMS was figured out through expert interviews and survey. Then better ways to implement the system were drawn based on the problems. To effectively manage the cost of public construction project, basically project cost should be estimated accurately in planning stage and managed based on it to have a project complete within the budget. In addition, the cost need to be managed in more systematic ways in terms of data collection and analysis, and the autonomy in managing the project cost given to the project owner needs to be expanded. Most of all, proper budget should be provided to prevent a project from delay through setting the priority of projects and proper budget allocation based on the priority.

Recently, a size of the domestic construction industry Has been reduced rapidly, and its economic slump Has been continued with the government real estate stabilization and tax policies. Moreover, as the reconstruction of apartments that has been added high value to the construction companies has been on the stake of high risk with delays of reconstruction start and finance restriction policies, an uncertainty of the construction markets and the competitions between the construction companies has been increased. At this point, the establishment of a collaboration relationship between construction companies has been recognized as one of the methodologies to respond actively on these uncertainties and fierce competitions. A collaboration relationship between construction companies is based on the balanced cooperation relationship for surviving together, and should be maintained on the complement and specialized collaboration between big, middle and small contractors. This paper propose a model of practical collaboration relationship to cooperate together between prime and subcontractors in Korean construction companies based on the analysis of questionnaires to the collaboration status between general and subcontractors in the Gangwon area.

According to the recent "Status of Industrial Accidents at the End of December 2020" released by the Ministry of Employment and Labor, each industry is subject to industrial accidents. The number of accident deaths by construction industry, accident deaths by accident type fell, and accident deaths by workplace size were 5 to 49, indicating that most accident deaths occurred due to falling accidents at small construction sites. Therefore, urban living houses are small construction sites, and the probability of falling accidents is very high. Fall simulation training for disaster occurrence is conducted mainly by large construction ordering organizations in the public sector, and it is the first case in Korea that a housing construction company has conducted at a small construction site. This study analyzed and presented the definition, construction characteristics, and safety management status of urban living houses, and developed and spread an emergency relief procedure manual in the event of a fall accident to minimize deaths.

Although pilot projects have been actively carried out from 2017 to present to institutionalize CM at Risk, one of the major tasks for innovation in the construction industry, standards and processes related to Design VE, a key tool for determining GMP in the pre-construction phase, have not yet been established. Therefore, through research and operation status related to CM at Risk and Design VE, and survey on project participants' perception, the problem of the existing design VE process was derived, and the design VE process suitable for the CM at Risk project was proposed. The application plan was proposed in three aspects: Schedule, Cycle, and Process, and the appropriateness and applicability were verified through FGI. The results of this study are expected to be used as basic data on the establishment and legislation of order standards to be made in the future.
