This research traces the history of legislative matters regarding the enactment and revision of laws and regulations related to the outdoor landscape in apartment complex. The years before 1976 can be classified as 'a period of darkness' for the landscape in apartment complex due to absence of landscape legislation. From the year of 1977 when the landscape planting and mere necessities were carried out according to the local administration's building standard to the year of 1990 can be classified as 'a period of quickening'. The year of after 1991 when the enactment of the code#32 called "the green space in site" in the "Korea Building Code" and the "Korea Housing Standard & Regulation" was made, and various construction regulations and provisions were revised in order to improve the scantiness of the apartment complex and its environment should be called 'a period of development'.

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.

According to Korean Architectural Standard Specification (KASS) , at the design stage of the specified concrete strength, strength correction with each temperature level should be considered to secure required strength at 28 days even in low temperature condition, In this paper, the period for the strength correction at the stage of mixture design of the concrete using ordinary Portland cement(OPC) specified in KASS was determined with each region of south Korea based on the meteorological data of KMA(Korea meteorological administration) by applying KASS-5 regulation. In case of 28 days of strength control age, the period for strength correction with 6MPa was calculated to $50{\sim}60$ days and, with 3 MPa. to around 80 days. The period for the strength correction was shown to be decreased with the rise of altitude. The period to consider the delay of the strength development due to low temperature including the period of cold weather concrete was nearly 7 months around 1 year. References for determining the strength correction factors with each region of south Korea was provided in this paper. Further investigation of strength correction of the concrete containing blended cement is to studied.

The current dual-watchdog estimation system has individually calculated the construction, the engineering and the procurement cost. The dual-watchdog estimation system is inefficient and prolonged estimation period because of the lack of the interoperability and the difference of material unit cost and construction unit cost. In order to resolve this problem, new estimation software was developed. The estimation software is developed by making up for the weak points in existing estimation method. The cost data with the same standard is the key point. And this software enhanced accuracy and speed of the data search in stylized estimation standard. A summary of the construction, the engineering and the procurement cost was generated in this estimation software. The unit rate about the labor cost, equipment and expense through a sheet was handled. The developed estimation software has five categories on engineering cost, procurement cost, construction cost and subcontractor management sheet. In this study, the estimation software to supplement the faults of the existing estimation method was developed. And estimation software on petrochemical projects increases an efficiency of the estimation work.

Domestic construction industry has experienced many difficulties as it has been on a downward. It's a way that active modular structure market to solve this problem. However, as Modular structure technical standard in Korea is in the early stages, our modular factory maufactured rate is almost 40% lower than overseas. Besides, there is less design diversity so it just applies for a few buildings like low-rise building and general group barrackes. To deal with these problems, it is essential to modulating the equipment which can improve the production rate. This will help to ensure the quality, shortening of the construction period, the reduction of labor costs. We have defined the name of segmented by each installation location of the equipment to modulating equipment. And it was examined the suitability of the modulating of the location-specific utility system. The results of the analysis are discussed on the page.

During the construction project period, a lot of change orders happen in the design and construction stage Especially, The change order during construction stage causes the huge construction cost increase and duration delay. Accordingly, research on the change order of the construction stage is being progressed relatively active in the design stage, but the design changes are rarely made. In the design stage, the owner has to pay a design addition cost when change order due to the demands of owner happens. However Korea has not the specific standard about design additional cost in design stage. Therefore, this study analyzes problems of design additional cost estimation methods through the case study, and then indicates the method that the ratio distributes to details dividing design tasks and the method of the PM(Project Management). Eventually, this study expects to minimize claim related the design additional cost in design stage.
