摘 要
建设项目造价管理是控制建设项目投资,提高投资效益的一项有效途径。但是在建设项目实施过程中存在许多不确定性,充满了风险,由于这些风险对建设项目的作用,使得建设项目造价也存在风险性,基于这样一种认识,我们将建设项目造价分为:确定性造价和风险性造价。风险性造价的发生具有随机性,它随风险的发生而发生,是建设项目造价管理的重点,但是现有的造价管理理论缺少对风险性造价管理的技术与方法,本文将重点对这些方法和技术进行研究,试图从中找出解决我国造价管理失控的方法。
本文首先介绍了建设项目造价管理和建设项目风险管理的相关概念,在分析建设项目造价风险性及建设项目风险性造价与建设项目风险间关系的基础上,构建了建设项目造价风险管理模型,实现项目风险与风险性造价的集成管理。本文分两部分内容来对这一理论进行阐述,在第一部分内容中提出了建设项目造价信息分析方法,并对建设项目造价影响因素进行了详细归纳,重点介绍了建设项目造价风险识别与度量方法和程序,采用蒙特卡罗模拟法实现了建设项目的全风险造价的计算。
在第二部分内容中详细介绍了建设项目风险性造价的控制流程和方法。
本文通过研究分析,说明了蒙特卡罗模拟是有效的造价计算方法,论证了进行工程造价风险管理的可行性及必要性,为建设项目造价风险管理提供了技术上和方法上的支持。

Abstract
Construction project cost management is an effective method to control projectinvestment and increase income. However, much uncertainty and risk exist in the course ofproject construction, which brings uncertainties to the project cost. Therefore, constructionproject cost can be divided into certain cost and risk cost. The risk cost happens randomly,which lies on the occurrence of related risk. Risk cost is the focus of cost management, butcurrent cost management theory fails to provide guaidance in this area. The thesis will focuson the technique research on risk cost management, and propose an resolvent for the wide cost management in China.
The thesis first outlines the definitions of construction project cost management andconstruction project risk managementand studies the relationship between project risk andrisk cost, based on which the cost risk management model for construction projects isdeveloped to realize the integrative management of risk and cost. Two sections of the thesisare organized to systematically study this theory. The first one proposes the research methodon construction project cost information, and specifies the factors influencing costs. Then thetechnique of detecting and measuring the costrisk factors is studied, and Monte CarloSimulation is introduced to calculate the risk cost. The second section investigates the method of controlling construction project risk cost.
The thesis proves that Monte Carlo Simulation is an effective cost calculation method,and analyzes the feasibility and necessity of the project cost risk management, whichprovides the technical and methodological support for the risk management for construction projects.
