Saemangeum development project is the world's largest tidal flat reclamation project. It is currently under construction, and proceeding with phased developments. The construction of agricultural areas within the Saemangeum reclamed lands is also a part of this project. These areas will have multi-functional complexes aiming to produce mainly eco-friendly horticultural crops and livestock products for the purpose of export. The major concern is to obtain sufficient water with appropriate quality to supply to those areas. The objective of this study is therefore to provide available water supply plans for agricultural purpose, especially for horticulture and livestock complexes. Alternative methods for water supply are purifying water from the Saemangenm lake or using water supply services providing by K-water or local governments. This study investigates to find an economical water supply plan through comparisons of these methods. As a result, the water purification method with Saemangeum lake water could be advantageous for given water supply conditions to horticulture and livestock complexes.

In 2006, Korean Government decided to relocate the several Government bodies and public institutes. They include total of 49 central Government agencies, semi-government agencies, and 17 national research institutes. The completion of the relocation program has been set to be final in 2030. The target population for the city plan is set to be 500,000. The goal of MAC is first to complete the first phase of the program by 2014 within the budget. In order to achieve the goal, considerable time has been spent to properly establish the program management system. The success of MAC's Multi-function Program Administration System is too early to determine as it is still in progressive. The success depends on the operations not the development.

In many urban cities, mixed-use development is becoming increasingly essential for the creation of an attractive and sustainable environment that promotes economic vitality, social equity and environmental quality. Due to the differences in scale, scope and intent, certain aspects within the project delivery process of mixed-use are not the same as "conventional" single-use projects. The objective of this paper is to highlight these aspects. Two cases in Southeast Asia serve to illustrate the uniqueness and challenges of mixed-use. In conclusion, the differences between mixed-use and single-use are evident in terms of the diversity of team members, the necessity of multiple market analyses, and a multi-layer (versus single-source) financing structure. Finally, issues concerning ownership tangles, land assembly, planning and application procedures, investment criteria of institutions have been identified as major pitfalls.

Front end planning is arguably the most impactful process in the successful delivery of capital projects. Organizations expend substantial effort in this planning process, intending to minimize risk and promote project success. This process has been well documented, including critical technical components, as well as the importance of team collaborative components. As organizations continue to pursue large projects with multi-national participation from sponsors, designers, contractors and suppliers, the importance of collaboration on a global scale during front end planning becomes more important, not less. This paper will outline research performed over the past two decades giving the basic components of the process and the value of global collaboration. It will provide guidance to project participants in pursuing successful planning.

The populations of major cities in Australia are increasing rapidly and facing an acute housing shortage. Traditional apartment procurement techniques involve lengthy lead-times and factory-based, or offsite manufactured (OSM) multi-storey apartment buildings may offer the opportunity to help fulfill the need by significantly reducing build times. Other advantages of OSM may include superior quality, low weight ratios, economies of scale achieved through repetition of prefabricated units, use on infill sites, sustainable design standards and better occupational health and safety. There are also positive labour and training implications, which may help to alleviate an industry-wide shortage of skills through use of semi-skilled labour. Previous uncertainties about the adoption of offsite due to the high capital costs and perception issues were generally based on pre-cast concrete structures, which are quite a different building type in terms of flexibility, construction, delivery and finishes. Identification of drivers and constraints assists in the determination of current industry status, allows for a benchmark to be established and future opportunities and directions for OSM to be determined.

As the scale of construction work is enlarged, complicated and diversified, construction information from the large number of construction sites is happened and reported to the head office. To control much information generated in construction sites simultaneously, the necessity of supporting system which can extract necessary information is increased. However, compare with large companies, medium-sized companies's organization of head office and management system is weak, so it's difficult to manage multi-projects. Among these site managements, resource management is an important management area. But, resource planning is based on experience and judgement and have not associated with schedule information. So when schedule if changed, the plan must be amended manually. This study investigates material-planning model for multi-project management which is connected with daily report system and scheduling software.

In this research, it is proposed that optimization method is introduced and applied to the design of pipeline system in multi-regional water supply project, which has been constructed to settle the regional unbalance problems of available water resources. For the purpose, interface programs are developed to integrate linear programming model and KYPIPE model which is used for optimization and hydraulic analysis, respectively. The developed program is applied to the pipeline system design of multi-regional water supply project. The optimal diameters from the application of linear programming technique are compared with those from conventional method that is time-consuming and tedious trail and error process. Since the conventional design largely depends upon the experience of designers and the results of general hydraulic analysis, it can not be reasonable and consistent. The application of linear programming technique can make it possible to design pipeline system optimally by using same design factors of general hydraulic models. The model can select commercial discrete pipe diameter as optimal size by using pipe length as decision variables. The developed model is applied to Pohang multi-regional water supply system design with two different objective functions, which are initial construction cost and annual cost including electric cost. As results, it is calculated that the initial construction cost of 1,449,740 thousand won is saved and annual cost of 128,951 thousand won is saved for a year within study year. Also, the optimal site of pump station is selected on 5th pipe, which is located between the diverging junction to Kangdong(2) province and the diverging junction to Cheonbuk province. It is explained that pump cost is less than pipe cost in this application case study due to little pump station scale. In the case of water supply with large pump capacity, it is reasonal that the increase of pipe size is more efficient instead the increase of pump station capacity to save annual cost.

The Four Major Rivers Restoration Project was the multi-purpose green growth project on the four major rivers in South Korea. However, the Four Major Rivers Project has attracted significant criticism from various social groups and wider international groups, e.g. Friends of the Earth. This study reviews the four river restoration project from the standpoint of an evolutionary process of water paradigms. It reveals that the project has achieved its intended purpose yet, suggesting to apply some valuable lessons in the consideration of the integrated watershed management system. Finally, it urges to introduce tentatively named "Basic law on Water Management" preceded by enacting ordinances at local level, because it'll help us find out ways ahead for the Integrated Water law.

Modern cities' paradigm is rapidly changing to evolve into multi-functional spaces including living space, culture, welfare and environment. Therefore, upon these changing needs, the cultural images and the quality control became major issues in this area. This thesis will examine cultural contents development, a successful case-study, and the analysis of complex space development plan. Thereby each development case in cultural contents area will be extracted and it will seek to find out how they could make a complex cultural space. Moreover, the role and boundary of each Project Management case and Project Manager will be analyzed. The analysis showcases the importance of comprehensive and systematic management system. As a result, along with the recognition of the strong ground for Project Management and Project Manager, comprehensive planand the most effective management system for various complex cultural space development plans would be PM application which is expected to be new alternatives to improve complex space development quality.
