近十多年来,城市公用事业工程建设为社会带来了极大的经济与效益,是国家投资的重点项目之一,国家投入的资金逐年递增.然而,在建设过程中由于错误地对工程各方面的估计,造成概算超过了估算,预算超过了概算和结算超过了预算的现象,所以工程造价方面就成了非常重要的一点,包括对工程的计价与控制等复杂工作,对工程进行时各种耗费进行合理地规划,更有利于工程的顺利进行,本文将通过理论分析和案例分析两方面来研究造价的确定与控制. Over the past decade or so, the construction of urban public utilities has brought great economic and social benefits to the public and is one of the key projects invested by the state, and the funds invested by the state have been increasing year by year. However, in the process of construction, Estimates of various aspects have caused the estimates to exceed the estimates. The budget exceeded the budget estimates and the settlement exceeded the budget. Therefore, the project cost has become very important, including complicated work such as valuation and control of the projects, Various expenses are reasonably planned, which is more conducive to the smooth progress of the project. This article will study the determination and control of the cost through theoretical analysis and case analysis.
