Forecasting cash flow is very important but is difficult and complicated to analysis in high-rise development projects. And An expected value which was forecasted on the early stage is likely to fluctuate due to uncertainties around such complicated huge project to consider the probable uncertainty. There are not objectified method which are able to cope with uncertainty of project, and feasibility study based on selected financial analysis does not include liquidity of cash flow. Through such a stochastic method, developer can cope with cash flow fluctuation and set up a financial plan. Also this study is meaningful for laying the foundation for high-rise development project and feasibility study as well as the suitability and accuracy of feasibility study. Analysis showed that NPV and IRR include residential apartments shows surplus revenue as return of apartments offset deficit of hotel and office. Factors influencing the project feasibility for high-rise development project are sales account of $1^{st}$ year and annual vacancy rate of office.

a. 구조체가 받는 힘 중 횡력을 모두 메가컬럼이 부담하고, 내부외 보와 기둥은 중력방향의 하중만을 부담한다. b. 메가컬럼 안으로 코어 기능을 모두 넣어 자유로운 평면구성이 가능하다는 것이 최대의 장점이다. c. 모듈의 반복적인 조합을 통해 나온 유닛의 재조합으로 메가컬럼을 형성하고, 거대한 이 기둥을 외부로 노출시켜 구조미를 추구한다. d. 2009년 9호선 연장을 앞두고 서울의 최고 중심지가 될 강남역을 사이트로 정해 초고층 건물을 건축하여 도시경관을 더 돋보이게 한다.

Constructing super-tall buildings is significantly different from constructing general ones in every technological and managerial aspects. Especially lift-car operations planning and management is one of core parts among various management techniques required during the course of the whole construction process of the super-tall buildings because vertical movements of physical resources enormously affect the efficiency of the construction processes. However, discrepancy between lifting plans and actual lifting operations causes serious efficiency problems. As an effort to solve the problem, this research suggests an improved method of estimating resource-based lifting load. The computing model developed as a result of this research facilitates more accurate computation of the total operation time and the maximum lifting capacity of the lift-cars. Further, this research can be developed as a decision support system for the total lift-car operations management.
