Risk Management on Construction Project of Super High-Rise Residence

超高层住宅项目在设计、施工等阶段的全寿命周期风险管理的观点越来越受到重视。要求开发商承担风险，成本透明。在超高层住宅建设项目中，项目经理需要形成从项目开始到拆除全过程的长期风险管理计划。建筑师/工程师、总承包商和施工管理者也不可避免地要进行量化的风险管理，并保持明确的意外开支。另一方面，据说近畿地区未来30年内将发生大规模地震。本研究系针对一超高层公寓大楼落成后之风险评估。排除了人为判断的个体差异，提高了分析的科学性。在本研究的第一阶段，对风险因素及其管理系统进行了研究。然后，随着项目的复杂化，开发了有效支持风险策略的系统。通过一个具体的超高层住宅项目的生命周期，从每个参与者的角度来指定风险事件。其次，建立了包含各种风险信息的数据库，并建立了在固定的风险策略预算内定量选择最优策略组合的数学模型。最后，开发了由它们组成的项目生命周期风险管理系统。

The view of "Life cycle risk management" that contains after a super-high-rise residence is completed as well as design and construction phases becomes more important these days. Risk taking of developer and transparency of cost is requested. In a construction project of a super-high-rise residence, the project manager needs to form the long-term risk management plan which covers the problems from the beginning to the time of demolition. It is also inevitable for architects/engineers, general contractors, and construction managers to make quantitative risk management and to keep clear contingency cost. On the other hand, it is said that the large-scale earthquakes will occur within 30 years in the future in Kinki region. This research deals risk evaluation after a super-high-rise condominium is completed. The individual variation of the human judgment is excluded, and scientific analysis is improved. Risk factors and their management system are examined at the first stage of this research. Then the system which supports a risk strategy effectively is developed as a project becomes complex. Through the life cycle of a specific super-high-rise residence project, risk events are specified from a viewpoint of each participant. Next, the database is developed which has various kinds of information about the risks, and the mathematical model is formulated which choose the combination of the optimal strategy against a risk quantitatively within a fixed risk strategy budget. Finally, the project life cycle risk management system is developed which consists of them.
