70년대 이후 급속히 건설된 공동주택은 시간이 경과함에 따라 구조체와 시설이 노후화 되면서 유지관리 비용이 상승하였고 또한 경제성장에 따른 생활수준의 향상으로 인해 주거공간으로의 기능을 상실하게 되었다. 이러한 이유로 인해 공동주택 재건축 수요가 창출되었고 90년대를 기점으로 활성화되었다. 그러나, 사업시행주체인 조합임원의 대부분이 비전문인이기 때문에 사업시행에 않은 문제점들이 발생하게 되었다. 본 연구에서는 이러한 문제점들을 해결하기 위한 방안으로 재건축조합의 전반적인 업무를 대행하고, 공정하고 투명한 절차에. 의해 사업을 추진할 수 있도록 공동주택 재건축사업에 대한 CM의 적용방안을 모색하고자 하며, 특히 재건축사업 추진단계별 CM업무를 제시하고자 한다. 또한 향후 재건축사업의 CM적용시 현실적으로 활용 가능한 업무를 중심으로 제안하여 조합과 CM회사에서 이를 활용할 수 있도록 하였다.

High-rising buildings are a sort of solution to recent cities. Till now real estate development was concentrated in new development on vacant lots, and it resulted urban sprawl. Generally large cities are confronted with the exodus of industry and population from city. High-rising buildings solve many problems associated with this problem. The purpose of this research is to identify the effect of super high-rise mixed use building project process on apartment price. For this study, the hypothesis is that price of apartments is influenced by project process of super high-rise mixed use building. The study concerned 4 variations of project process that is building permits stage, sale stage, construction starting stage and stage of moving into building. The target projects of buildings are selected by number of floor(over 40 floors) and construction time. And 48 apartment complex are selected around super high-rise mixed use building. This study uses hedonic price function to analysis effect of project process of super high-rise mixed use building. A price of apartments is defined as a dependent variable. Characteristics of residence, complex, district and super high-rise building are defined as independent variables. The results are as follows; first, there is no error in price model of this study. Second, it is found that apartment price was influenced negatively by building permit stage and sale stage of super high-rise mixed use building. But that was influenced positively by construction starting stage and stage of moving into building of that. Third, as the project process of super high-rise mixed use building was proceeded, price of apartments was increased.

The basic type construction cost which is the base of the building cost estimation is being adjusted according to the price changes by utilizing the apartment construction cost index in order to flexibly operate it. In this study, we analyzed the change trends and characteristics of the housing cost index for the basic type building cost model project operated from September, 2012 to March, 2018. As a result, the increase in material costs is slight while the share of the labor cost increased in the construction cost due to the rise of labor unit price, leading to a perceived increase in sensitivity of labor costs. We should be careful to keep the sensitivity of the material cost and the labor cost to an appropriate level so that the index may not be distorted.

Consumers demand an increasing variety of requirements for the residential space as the quality of life improves. However, many apartment buildings with the bearing wall structure cannot meet such demands in Korea. A lot of construction resources are squandered and wastes are created as this type of residential buildings is reconstructed. The life of apartment buildings needs to be extended on the basis of easy remodeling of internal space in order to overcome the limits of the bearing wall structure. This research project aims to propose the Rahmen composite frame concept for the long life of apartment buildings. The Rahmen composite frame is expected to have better structural performance, constructability and economic feasibility than the bearing wall structure.

The ultimate goal of construction is to complete the given work in the most economical and safest way within the required construction period while meeting the quality standards specified in the design drawing. There are a few characteristics of finish work. First, executed in subdivided processes, finish work involves a very diverse and complex structure. Second, there are no criteria for each segmented process with regard to the appropriate time of input. Third, it is not very necessary to set priorities for lead and lag works. This study intends to provide information on the completion of a project in accordance with the required duration by setting priorities in the delay of each detailed process of finish work to minimize delay in finish work. In this study, finish work is divided into wet work and other types of finish work, and the importance of each process is classified based on the given details of each process. In addition, the study employs a survey to analyze delay factors of a designer, a constructor, and a supplier. Using the survey results, the study sets priorities in delay of final work to provide information on the completion of an apartment project within the planned construction period.

The safety inspection cost of the construction work was based on commercial facilities classified as a single building. Therefore, it is not possible to fully reflect the characteristics of the multi-building construction project such as apartment houses. Therefore, this study suggests a reasonable estimation model that can fully reflect the characteristics of the multi-building construction project. The safety inspection cost estimation model proposed two models such as construction cost ratio method and cost plus fixed fee method. And these models were simulated by the apartment construction work and compared with the current standard. As a result, the current construction cost ratio method has shown that the safety inspection cost tends to be overestimated as the construction size increases. Therefore, the proposed model has reflected characteristics of the multi-building construction project, so that it can reasonably estimate the safety inspection cost more than the current standard.

This study aims to analyze the on-site improvement area of residential environment improvement project based on research results derived from the on-site and questionnaire survey in case of Daegu. The main findings are as follows. First, residents complain about delay of project completion because a long time has been passed after on-site improvement area was designated. Experts and government officials agree that a new method of development is required. Second, future development should discriminate on-site improvement area according to its level of project completion. The area should be classified into project completion areas and on-going area, and new methods, such as redevelopment, apartment-housing construction method, should be allowed. Third, for better management of on-site improvement area, laws and regulations must be ready and government's will for improvement is crucial.

Accurate construction cost estimation in the initial stage of building project plays a key role for project success and for mitigation of disputes. Total construction cost(TCC) estimation of apartment projects in Vietnam has become more important because those projects increasingly rise in quantity with the urbanization and population growth. This paper presents the application of artificial neural networks(ANNs) in estimating TCC of apartment projects. Ninety-one questionnaires were collected to identify input variables. Fourteen data sets of completed apartment projects were obtained and processed for training and generalizing the neural network(NN). MATLAB software was used to train the NN. A program was constructed using Visual C++ in order to apply the neural network to realistic projects. The results suggest that this model is reasonable in predicting TCCs for apartment projects and reinforce the reliability of using neural networks to cost models. Although the proposed model is not validated in a rigorous way, the ANN-based model may be useful for both practitioners and researchers. It facilitates systematic predictions in early phases of construction projects. Practitioners are more proactive in estimating construction costs and making consistent decisions in initial phases of apartment projects. Researchers should benefit from exploring insights into its implementation in the real world. The findings are useful not only to researchers and practitioners in the Vietnam Construction Industry(VCI) but also to participants in other developing countries in South East Asia. Since Korea has emerged as the first largest foreign investor in Vietnam, the results of this study may be also useful to participants in Korea.
