摘要
钢筋工程在建筑造价中占有较大比例,而钢筋市场价格变化剧烈,导致工程预算与决算存在较大差异,给工程造价控制带来困难。通过郑州市和北京市不同年份、不同计价模式、不同结构类型共40个建筑工程实例的造价分析,发现砖混结构中钢筋工程占土建造价的比例约为18%;框架结构约为31%;剪力墙和框架-剪力墙结构相差不多,均为32%左右。为了合理控制建筑造价,建议在合同中对钢筋价格变动引起的土建造价变化作出专门约定,以减少造价纠纷。
The cost percentage of steel reinforcement in building is high. However, the price of steel reinforcement increases dramatically in China, which result in the great difference between cost estimation and final account. Based on case analysis of 40 projeets, we found that the cost percentage of steel reinforcement in masonry structure is about 18%, in frame structure 31%. In shear wall structure and frame- shear wall structure the percentages are very close, they are all 32%. It is advised that for the purpose of cost control, there should be some special provisions in the contract stipulating the price of steel reinforcement and its changing.
