The Construction Standard Unit Price (CSUP) sets the standard for calculating the estimated construction cost. The CSUP is used as basic data for preparing a standard price for public construction. Currently, the CSUP is calculated in consideration of the market and construction field conditions. However, a long-term management plan was established to prepare revised standards. As part of the plan, a field survey was conducted on changes in construction conditions and market prices. However, the plan continued for more than 5 years. Thus, the plan has a problem of difficulty continuously managing primary activities that have high importance and high price volatility. Therefore, to efficiently manage the CSUP, this study identifies the primary activities of the CSUP and presents a management plan. Through importance analysis and unit price volatility analysis, 242 primary activities in 35 activity groups were identified. Also, a management plan is presented based on the importance levels of activities. The primary activities and management plan could enable the timely revision of important activities. The results of this study provide a base for reflecting the appropriateness of construction cost criteria on time.

The purpose of this study is to provide a basic datd for establishing a basic park management plan for Bulamsan Urban Nature Park. This research surveys very closely about the present condition of the natural ecosystem based on the examination and analysis of the present condition. This research suggests development and management methods for environment-friendly park by understanding damages on the ecosystem due to overuse, as well as park facilities and their effects on the surrounding environment, using quantative analysis. The three steps: researching the present condition research, ecosystem evaluation, and park management plan were taken in order. The present condition research is based on the general condition, natural environment, and natural ecosystem data. In the ecosystem evaluation, wildlife habitats evaluation, landscape evaluation, and biotope type research which is a materialized form of the plant ecosystem were excuted based on the present condition research data. In the park management plan step, 1) classified ecosystem and landscae preservation zone, ecosystem protection zone and ecosystem restoration zone as ecosystem and landscape preservation plan, 2) plannings for ecosystem, fine landscape preservation, damaged area restoration and recovery plan were established in order to suggest environment-friendly plan,

It is essential to consider strategies, spatial planning, and reflection of sustainability for the creation of sound urban spaces. To this end, there is a need for plans that can secure better sustainability through strategic environmental assessment (SEA) of plans. This study examined the literature and available precedent to develop a SEA model for administrative plans for urban development including metropolitan plans, urban master plans and urban management plans. In the course of development of the model, environmental issues associated with the urban plans were analyzed by classifying them into ten categories, including "spatial planning," "conservation planning," "greenbelt systems," "habitats." and etc. according to their rank. Furthermore, those issues were reflected on the development of environmental evaluation indices for the plans. Overall and detailed environmental indices that can be applied to the administrative plans for urban development including metropolitan plans, urban master plans and urban management plans were devised for five stages: (1) Establishment of development goals and strategy, (2) Analysis of current status and characteristics, (3) Conceptualization of spatial structure, (4) Planning for each department, and (5) Execution and management. Sub plans are more detailed and concrete. Criteria based on the evaluation indices, when performing evaluations on plans based on each environmental assessment index in reference to experts and the literature, were used to forecast their effects, i.e. whether they had a positive, negative, or no effect or relationship, or whether their effects was uncertain. Based on the forecasts, this study then presents means to establish more improvable plans. Furthermore, by synthesis of the effects according to each index and integration of the process, plans were analyzed overall. This study reflects the characteristics of the present time period based on issues in the SEA process and techniques in upper level administrative plans being newly established, and presents them according to the stage of each plan. Furthermore, by forecasting the effect of plans by stage, this study presents proposals for improvement, and in this aspect, can be meaningful in promoting plan improvements through SEA.

The case for study in this paper is the Main Plan and Management for the Fukutoshin; the restructure of Nishi Shinjuku, This plan was first outlines in 1960, and includes a vast area of 96 ha for redevelopment. It aims to create a totally new center in the city. This was the first case in Japan, and in the world of a plan of these magnitudes. involving urban landscape restructuring from three points: Landscape (open spaces for public use: the Shinjuku Central Park and the surrounding area of the buildings), transport and commercial building developments. The Landscape plan for the green areas was decided in a way to compensate the population of the area and the visitors. As a rule, high-rise building constructions are placed each one in single lots and are surrounded by open spaces and greenery. Pedestrain areas are widened and also connected by bridges in a way to allow free circulation, and interconnection between the constructions and the green areas. Another important factor is the role that Private Corporation, and public interest plays. Joining these two forces has allowed the concretization of this project. This interpolation between public and private roles was an innovation in Japan, and it also the key for the concretion of the project. The historical review of the process and management of this project help us to put into perspective the introduction of new concepts and ideas, which were not related at that time to traditional Japanese Landscaping. Furthermore we are better able to understand the substantial increase in the percentage of land dedicated to green areas in contrast to the typical standards of Japanese cities.

The Citarum River Basin is the biggest river basin in West Java Province, Indonesia and it plays strategic roles in providing water for irrigation, domestic and industrial uses, and power generation, besides controlling the flood during rainy season. Flowing through seven major cities makes the river flow and water demand are vulnerable to land use change around the river. The present water resources management has involved the regulator, operator, and users in deciding an appropriate water management plan for the entire basin. The plan includes an operation plan for three reservoirs, construction or maintenance of the river channel, and water allocation for all users along the river. Following this plan, a smaller operation group will execute and evaluates the plan based on the actual flow condition. Recently, a deforestation, environment degradation, river sedimentation, a rapid growth of population and industry, also public health become new issues that should be considered in water basin planning. Facing these arising issues, a new development program named ICWRMIP was established to advance the existing management system. This program includes actions to strengthen institutional collaboration, do the restoration and conservation of the river environment, improve water quality and public health, also advance the water allocation system. At present, the water allocation plan is created annually based on a forecasted flow data and water usage prediction report. Sometimes this method causes a difficulty for the operator when the actual flow condition is not the same as the prediction. Improving existing system, a lot of water allocation studies, including a development of the database and water allocation simulation model have been placed to help stakeholders decide the suitable planning schemes. In the future, this study also tries to contribute in advancing water allocation planning by creating an optimization model which ease stakeholders discover a suitable water allocation plan for individual users.
