Resident participation or tenant empowerment is becoming an important concept of planning, provision of welfare services, and management of housing. It can be motivated by three variables: shared goals, shared values, and sense of community among residents. Theoretically, the more each of these three variables, the more likely people will be to participate. The purpose of this study was to identify the perception of management staff on residents' participation in public rental housing. For this, 198 management staff of public rental housing under Korea Housing Management were surveyed using questionnaire distributed by email during February 18 to 27, 2009. Only 33.3% of the public rental housing complexes surveyed constituted Residents Representative Committee. Most of the respondents showed negative perception of resident organizations and their roles as an meaningful way to communicate with them on the management system. Several ways to enhance the resident participation and to reduce housing and living cost burden of residents in public rental housing were suggested as follows: development and distribution of education and service program inspiring the residents' empowerment, enacting a provision of Tenants Representative obligation in Rental Housing Act, and so on.

The aim is to get comprehensive view point for the price of apartment. Apartment construction cost is the sun of land cost and building cost. Land price reflects the value of location where building stands. When the gap between price and affordability is narrow enough, effective demand promote apartment construction. The today's trends of rising price, which began in apartment housing, spreads to real estates market and finally overall consumer price. Problem is that price is decided only by supplier's interest. Equilibrium-pricing is common process in housing market. However it is important to review hedonic price and the factor of housing services and focused on the affordability of demanders. AHP analysis was used to study real needs and preference of demanders and dealt with 200 interviewees with brief checklists. We found that social factor is more important than building cost or site development. Especially location of apartment is most important to affect environment quality and accessibility to facilities.

Recently a great deal of people are taking legal action against the housing provider due to the defects of their Apartment house. And most of the housing companies are spending a huge amount of expenses and efforts to keep their brand value. This essay will carry out time series analysis the 20 housing district which are constructed by huge construction companies. This analysis itemised by metropolitan area(Seoul) and others to keep the degree of reliability, and converted future defect maintenance cost into current cost applied by discount rate to figure out suitability of defect maintenance cost. Even though, this essay is not able to represent standard of defect maintenance cost due to the insufficiency of record, while it will be assisted as a referance when long-term record of time series is estabilished.

This study aims to suggest the method to enhance the value of public construction project during contract review process considering budget reduction for project profit and public interest enhancement simultaneously. The main results of this study are as follows: (1) Current method are considered to be improved from the point that cost reduction through current method could influence performance of the object of contract without conforming to user requirements or facilities' function. (2) In order to supplement current process, the method to evaluate the variation of performance and value was established based on facility type, participants on each phase, and their requirement. (3) Case study was conducted to verify suggested method, and showed the successful application in enhancing the value of construction projects on public sector.

The purposes of this study are to find out the current status and features of earth housing, and to explore users' level of satisfaction and needs of improvement about earth housing. Primary findings are as follows: (1) The area of earth housing is generally 25-34 pyong and the construction cost of earth housing is usually 3,000,000-3,400,000 won per pyong. (2) The age of earth house users is generally forties, fifties, and sixties. And their occupation is usually retiree and farmer. The age of earth based pension users is generally twenties and thirties. (3) The construction method of earth housing is usually earth brick structure reinforced with wood structure and earth brick structure(adobe). (4) The finish of outer wall is generally earth brick laying and earth plaster. And the finish of inner wall is usually wall paper and earth plaster. Roof tile and asphalt shingle is frequently observed as roof finish. (5) Users' satisfaction about earth housing is investigated high level. Especially, the satisfaction degrees about faculty of humidity control, stink elimination, prevention from sick house syndrome, support for psychological stabilization and deep sleep are observed very highly. (6) Reduction of construction cost and prevention of crack is investigated as needs of improvement about earth housing.

Precast Concrete (PC) construction method can be the one that is suitable for long-life housing due to its merit in respect of maintenance and durability based on crack-free from mass production with indirect construction cost-saving-effect due to shortening construction period comparing to the conventional construction method, but it has the problem that causes the raise of direction construction costs. So, this study analyzed its economic feasibility of PC method whose maintenance and durability are excellent for underground parking lot of apartment house for accomplishing cost-saving long-life housing by applying the various structural system. In evaluation of unit module structural system, two-way PC system requires 10 to 28% more costs for frame work than RC rigid frames, and, one-way PC system 98~112%. Although it varies depending on the method, the costs are similar to RC rigid frame structure, provided a proper method is adopted. Also, Model 11, which was most economical in the evaluation, was applied to an real parking lot and about 2 to 6% of construction costs was reduced than RC rigid frames. This seems to be because, although PC system has a higher production cost, introduction of P.S (prestress) reduces member depth and, therefore, height, as well as the number of members per unit module.

Recently, maintenance of public rental housing becomes a critical issue because its expenditure possesses the majority proportion of life cycle cost. The countries, such as USA and Singapore, have introduced the approaches for advanced property management, which are cost-effective in the maintenance management. However, as maintenance management system becomes advanced, risks associated with its application are also increased. Therefore, it is needed to assess the appropriate applicability of public rental housing maintenance management considering the constrains in domestic construction industry. The main objective of this study are to investigate international cases and systems and to propose strategic introduction, which satisfies the regulations and policies for domestic public rental housing. In order to evaluate the suitability of the investigated systems, practitioners' opinions were reviewed through the questionnaire surveys using analytic hierarchy process (AHP). The surveys indicate that advanced asset management was the suitable process for managing efficiently domestic public rental housing. Moreover, the results showed each weights of considerable criteria for assessing the effective application of maintenance management, and would contribute to further detailed and systematic management.

This study beings from solving problems of permanent rental housing with environmentally-friendly planning factors to raise quality of life. Environmentally-friendly planning factors of permanent rental housing are derived from the study of references and green building certification systems of other countries. Surveys of inhabitants and experts give weights on these factors. Inhabitants do are focussed natural ventilation, life cycle cost, operation and maintenance cost. This reflects their interest in indoor amenity and a burden on the cost. Experts put more weights on pedestrian spaces considering the old and feeble persons and block planning. Besides, T-test pointed out that there are meaningful differences in land use between inhabitants and experts. Though inhabitants' opinion has priority because they are real user, experts' opinion which has the variety and the view in the long term should be reflected.

This study suggested a new model in consideration of long life and constructability of apartment house suggested in the former part. New model suggested the possibility of cost saving based on the idea that people trend to reject because of the recognition that the new model would cost a lot of expense which work as the barrier for the expansion and distribution at the local market so as to prepare the ground for its activation. The Study was aimed at verifying the possibility of cost saving through comparing it with the existing standard apartment house system centered on the skeleton and cladding system among the new structural design models suggested in the former part. Assuming that these existing standard both models should be changed structural design into new model system, the quantity volume, cost and construction period along with the alteration of finished materials between two models were compared altogether. Simultaneously BIM library was built for easy taking-off bill of quantity and consideration of working methodology for construction working cycle, which was translated into construction cost so as to derive the cost of the two subject systems to be counted. Through the analysis, it was concluded that new model would secure variability in the future and constructability along with shortening the construction period (29%) and achieve cost saving (13%) of construction against the those of existing model.
