According to the dispute cases filed for claiming the collective defect repair fees, inter-layer concrete joints turned out to be the most frequently disputed item. For this reason, this study selects the inter-layer concrete joints to further analyze the primary causes and details of each dispute case. From the results of this study, three primary causes of the disputes are found, which are 1) the absence of standard specifications for construction quality control and management after construction; 2) the absence of established standards for repair when construction defects are found. In order to prevent construction defects in inter-layer concrete joints, this study provides three suggestions including 1) the current standard specifications for inter-layer concrete joints should be further specified by the Ministry of Land, Infrastructure and Transport; 2) a construction defect should be judged according to the compliance to the standard specifications; and 3) a clear and institutional protocol needs to be established for defect repair in cases that new public apartment houses have been judged to have defects.

표준품셈은 우리나라 건설공사에 있어 가장 기본적인 요소이지만, 표준품셈이 공동주택 건설공사에서 실제 투입 되는 노무량과 큰 차이를 나타내고 있다. 따라서 실적공사비방식에 의해 공사비를 산정하는 것이 합리적인 대안이 될 수 있으나 원가계산서상에 각종 경비 등에는 정확한 노무량을 파악하여야 비용이 산출될 것이며 공사 진도 관리를 위해 투입 노무량을 정확히 파악할 필요가 있다. 본 연구는 2000년 이후 준공 된 수도권에서 공동주택 건설공사에서 표준품셈과 실투입 노무량을 조사하여 비교한 결과 다음과 같은 결과를 얻을 수 있었다. 실제 투입 노무량은 조적공 1.184인/천매, 미장공 0.048인/$m^2$, 방수공 0.039인/$m^2$, 타일공 0.059인/$m^2$이다. 표준품셈 대비 투입율은 보면 조적공 59.8%, 미장공41.3%, 방수공 31.5%, 타일공 34.3%이다. 방수공의 투입 비율이 가장 낮고 조적공이 비교적 높았다. 따라서 우리나라 공동주택 건설공사의 노무량은 실적공사비를 토대로한 원가계산이 바람직하지만, 공사관리에서 노무량이 주요 변수인 만큼 실제에 근접한 표준품셈을 지속적인 보완이 필요할 것으로 보인다.

Standard safety management costs can not be applied to each site with same rate, it is very difficult, because it depends on the experience, work method, work kind, work progress schedule, and hazard level of each construction company. Therefore, this study is to find out hazard level of each work kinds through questionnaire and interview and investigate analyze the status which standard safety management costs have been used. Also, this study is to show reasonable rates of standard safety management costs in construction industry and to set up countermeasures against those problem after reviewing its status in korea with in Japan and Europe. The domestic system of standard safety management costs is not considered in the foreign country, while only related subjective items have been investigated and evaluated for this study. This study is to investigate eleven project kinds of domestic system, first, and to investigate eleven items of apartment bldg, office, civil work such as bridge, tunnel, dam, plant etc, secondly. Additionally, three items of gymnasium, railway, particular steel tower are investigated in this study. Also this study is to investigate and analyze performed costs of presently processing worker finished work so that it shows a new reasonable rate against standard safety management costs in construction industry, in order to make basial data and material to be systemized.

Recently, a variety of special concrete structures have been designed in domestic and overseas construction markets and more advanced construction technology is required. Therefore, it is necessary to secure quantitative construction technology. For this purpose, it is essential to develop a standard reference material having a constant flow performance and quality to evaluate quantitative performance. On the other hand, the flowability of the concrete is greatly influenced by the flowability of the cement paste. Also, in consideration of design strength and workability, mix design is carried out at various mixing ratios according to the purpose of the site. Therefore, in this study, based on the derived components of standard reference materials for cement paste, we suggested mixing ratio of standard reference materials that can uniformly simulate the flow characteristics of cement paste according to W/C. As a result, it was found that the yield stress was determined by the ratio of water and glycerol but plastic viscosity was controled by limestone content. Finally, the ratio of standard reference materials to simulate the rheological range of cement paste by W/C was suggested.

This research developed construction cost forecasting model using Building Construction Cost Index, time series analysis and Artificial Neural Networks. By this model, we could calculate the forecasted values of construction cost precisely and efficiently. And we also could find out that the standard deviation of forecasted values is 0.375 and it is a very exact result, so the standard deviation is just 0.33 percent of 112.28, the average of Building Construction Cost Index. And it show more exact forecasting result in comparison with Time Series Analysis.

Apartments construction is a one of largest parts in buildings construction. In apartments construction, work interferences are frequently occurred in work processing because workspaces are very various and numerous. However, though work process is important for mainly influencing to the schedule, quality and cost of apartments construction, these work interferences are considered a kind of uncertainty, which is difficult to anticipate at construction planning stage, in work processing. Therefore, this study proposed the measures for work interference reduction in apartment buildings construction and the actual planning for practices. The results can be summarized as follows: (1) the standard of work process is checked regularly. (2) The scope of work and work process is adjusted. (3) The standard of drawings process and cost about work interferences work profess is established.

In our country, the application of the design method of face to face dimension in wall-slab apartment has passed 10 years. So MC design method has fixed in the design step to some degree. In Design and Work Execution of House the exclusive area of the apartment was calculated by face to face dimension. And the term of face to face dimension was known broadly to clients, construction company, etc. But design method of face to face dimension is not to simply extend the room size so far as wall depth in design process but to ensure the actual space should be considered with efficient use and assembly of building components. That is to say, Design method of face to face dimension is not to be defined by design step but to be related with construction and maintenance. However in construction process the point of face to face design method was not understood even now. So the purpose of this study was to extract the effect and question of face to face design method in construction process by survey of actual condition of structure and construction quality, and compare this result with existing construction method. The following project of this study is to survey of actual condition of interior components such as gypsum board, windows & doors etc. Therefore this study is to induce architectural long-life through architectural standardization construction and component's exchange, and, by the subject of the study on Apartment to have design guideline and basis for joining part between Gypsumboard and windows.
