造价、质量、工期是工程建设的三大目标，这三大目标并不是彼此独立的，而是相辅相成、相互制约的。建筑产品作为商品，由于其先定价后生产的特殊交易形式，决定了建筑产品的价格与质量、工期关系的特殊性。笔者这里仅从价格和质量的关系简单谈谈政府、业主、承包商在工程质量 Cost, quality, and duration are the three major goals of project construction. These three goals are not independent of each other, but complement each other and restrict each other. As a commodity, the construction product determines the particularity of the relationship between the price, quality, and construction period of the construction product due to the special trading forms that are first produced after pricing. The author here simply talks about the quality of the project of the government, the owner, and the contractor from the relationship between price and quality.
