In recent years, Owner, Architects, and Contractor are increasingly collaborating with each other from pre construction phase in construction projects, which is called Early Contractor Involvement (ECI). In Japan, the ECI method has been introduced in several public building projects since 2015. The purpose of this study is mainly to clarify the characteristics of the ECI method in Japan and to compare the contract clauses of the ECI method in the UK and the USA. The results of the survey are as follows. (1) the ECI method was supposed to make it possible to achieve appropriate quality, cost, and construction period by reflecting Contractor's technology and know-how in the design documents and specifications. (2) According to the database, there were 27 cases of the ECI method in Japan from 2015 to 2021, of which 13 cases for which bidding information could be obtained had a variety of technical proposals, mainly VE proposals, depending on the project characteristics. (3), Japan's ECI method has very much in common with SBC + PCSA in the UK. On the other hand, ECI Method in Japan differs from in the UK in that Owner, Architect, and Contractor enter into a partnership agreement, which is similar to ConsensusDocs CD541 in the USA. (4) The ECI method in Japan has the following problems: Owner depends on Contractor for cost control, the division of roles among project members is complicated, and more work from Owner than the DBB method are required.

In this era of information, the public library takes a important role in the local community. In several years, public libraries have been proliferated in our society. However, there have not been specific planning standards of space size for construction of public library. The situation has lead the local governments to the need of consulting for the construction and management of library in search of appropriate guideline. The research paper focuses on the result of consulting support project for construction and management of public library. It examines total 11 libraries which were consulted from 2009 to 2011. It examines the configurational differences between the first scheme from the local government and the final scheme after the consulting, and the percentages of gross areas of each parts of library, reference and reading area, office area, education and cultural area, and public common use area. The analysis concludes that reference and reading area increased by 6.4% from 34.1% to 40.5%, and public common use area reduced by 6.1% from 30.2% to 24.1%, which represents a certain tendency of the configuration ratio of the each parts. Thus, the paper could be a starting point of establishing planning standard of space size for public library.

As a way to raise the brand value of each area and activate local industries, public design projects have been competitively made. Meanwhile, public design has the characteristics of having an uncertain number of users, people with different interests, and management of the design by an administrative organization. Such characteristics may be obstacles to the results of public design and finally can cause many problems in a project's results. However, although most local governments have executed public design projects, systematic research for them and organized execution of the projects has been insufficient. For successful realization, proper organization, and consistent public design, research on a strategic design process is needed. Therefore, this study investigated the current status of public design projects to understand problems in the design process and solve them. The results are presented as follows: First, the design process for public spaces has a dual structure including a specialized process of design development in its execution and management and the execution process in the planning state is unsatisfactory and the process of designer selection is not consistent. Second, as a result of investigating the current status of the design process for public spaces, it was deduced that as most of the projects have been subjectively and temporarily managed by wholly charged organizations without specialized consultation or investigation with different related departments, there have been diverse problems in securing design quality. Third, as a result of analysing the specific execution processes carefully, it was suggested that problems in the process can be solved by decisions through consultation and discussion. As well supportive consultation systems should be used actively.

Economic feasibility analysis for the public projects such as sewer improvement project differs from the one for the project by profit organization in that the former has to take into consideration the public benefit that cannot be priced in the market. This study presents a model case study for the economic feasibility analysis for the sewer improvement project by the City of Gumi, Korea. The project is planned for the period of 2003~2021. It utilized Contingent Valuation Method(CVM) to assess the public benefits such as improvement of environmental quality and quality of life that can not be priced in the market. WTP(Willing-to-pay) of a household of the Gumi was estimated at 2,865 Korean Won on average. The result of an economic feasibility test including the estimated WTP indicates that B/C ratio of the project turned out to be 0.97, slightly less than 1. This study is the first application of WTP estimated by CVM to the economic feasibility analysis of public project in Korea. It is expected to contribute to the decision makings in the public policy domain as well as academic development.

The public SW market is 3 trillion won, which is less than 10% of the total SW market. However, due to the nature of the domestic market, it is an important market with a relatively large impact on small and medium-sized software companies. In this market, government is operating the Public SW Project Demand Forecasting System in order to support the marketing activities of small and medium sized SW companies and establish a fair market order. The current system has limitations such as lack of user convenience, insufficient analysis capability and less business connection. This study was conducted to identify the problems of these systems and to propose a new system for improving the convenience of users and expanding the information utilization of SMEs. To this end, we analyzed the requirements of each stakeholder. We proposed the 2-phased forecasting cycle, the management cycle, and the system life cycle of public SW projects and created a unified identifier (UID) so that the information of those projects can be identified and linked among them. As a result, an integrated reference model of project information management based on system life cycle was developed, which can explain the demand forecasting and project information, and the improved processes was also designed to implement them. Through the result of this study, it is expected that integrated management of public SW projects will be possible.

A protected area means a space designated and protected by law from development pressure and environmental pressure. It is mainly designated to protect specific ecosystems, natural landscapes, and cultural resources from irrational development (or damage), and involves policies of the public sector such as central and local governments. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has conducted conservation and restoration projects for preserving natural ecosystems and genetic resources. In order to conserve the ecosystem in the protected area, national and public organizations purchase private land and use it ecologically; in addition, ecological restoration project is carried out for the purpose of creating waterside ecological belt or preserving ecosystem. Land acquisition refers to the land where highly influenced by the water quality and need to restore, and purchased by negotiating with the landlord. Although the nation and public institution carried out ecosystem restoration project for partial purchase land in order to conserve ecosystem, it is below the expected effect due to lack of comprehensive management system and have some problems in restoration project and unification of management institutions. Land acquisition in Donggang River Basin Ecological Conservation area is initiated in 2005 for creating income of local residents and ecological restoration. However, the lack of overall management and awareness resulted in poor vegetation growth and poor response by local residents due to terrain exposure. As such, there is insufficient research on the current situation and systematic integrated management although the number of land acquisition is increasing year after year. Futhermore, overall recognition and follow-up monitoring of eco-restoration are still inadequate. Therefore, the survey on the awareness of the purchase land ecosystem restoration project is necessary for the efficient restoration project and establishment of the management strategy for land acquisition in the future. Therefore, in this study, we provide fundamental materials on further research projects by carrying out research on the awareness of ecological restoration projects in the Donggang River basin ecological preservation area.

The objective of this study is to analyze the properness, effectiveness and sustainability on the large-scale environment-friendly agricultural districts (LEAD). For this, we survey 11 public officers who manage the LEAD. Most of them aware necessities of LEAD project. They have a higher satisfaction and think that the project affect ripple effect and contribution on environment-friendly agriculture. Main performance expected of the LEAD project is a spread of natural circulation agriculture in connection with cultivation and stockbreeding. For continuance of environment-friendly agriculture after the project, it is necessary to find markets of products. Also policy making related with environment-friendly agricultural technique is required. The results of this study show that the LEAD project need a modification based on field and change of agricultural issues.

Nowadays BIM(Building Information System) is applied to the public construction delivery system. BIM can help communications between project applicants through the extraction of the exact and prompt information. It also increases the efficiency of planning, construction, economic feasibility and maintenance in the whole project. Due to increasing demands of BIM, project evaluation and its process on the final deliverables have been in major interests. Thus, through the analysis of the current BIM project, characteristics, types and applications have been researched. We have discussed completeness, relationship and planning of BIM data, which are the standards of evaluation.

The Public Private Partnership/Private Finance Initiative (PPP/PFI) schemes have made the private sector become a major participant involved in the development of infrastructure systems along with the government. Due to more integrated efforts among project participants and longer concession period, PPP/PFI projects are inherently more complex and risky. It is therefore very important to proactively manage the risks involved throughout the project life cycle. Conventional risk management strategies sometimes ignore managerial flexibility in the planning and execution process. This paper starts with a revised risk management framework which incorporates the real option concept. Following the presentation of the framework, a new risk classification is proposed which leads to different ways of structuring options in a project according to the stage of the project life cycle. Finally, the paper closes by discussing other issues concerning option modeling and negotiation.
