题目内容

某拟建3600m2多层砖混住宅工程与某已建成工程结构形式相同,只有屋面防水和保温工程不同,其他部分均较为接近,已知此已建工程的单方造价为590元/m2。拟建工程为复合彩板屋面防水保温,每平方米屋面消耗量为0.163m2。类似工程为SBS卷材防水,珍珠岩保温,每平方米消耗量分别为0.15m2、0.033m3。拟建工程复合彩板单价为215元/m2。类似工程的SBS卷材单价为50元/m2,珍珠岩单价153元/m3。类似工程的人工费、材料费、机械费、措施费、规费和企业管理费占单方造价比例分别为11%、62%、6%、4%、5%和12%,拟建工程与类似工程预算造价在这几方面的差异系数分别为2.01、1.06、1.92、1.02、1.01和0.87。问题:(1)应用类似工程预算法确定拟建工程的单位工程概算造价。(2)若类似工程预算中,每平方米建筑面积主要资源消耗为:人工消耗5.08工日,钢材23.8kg,水泥205kg,原木0.05m3,其他材料费占材料费的50%,机械费占定额直接工程费8%。拟建工程主要资源的现行预算价格分别为:人工22.5元/工日,钢材3.1元/kg,水泥0.35元/kg,原木1400元/m3,拟建工程综合费率18.5%,应用概算指标法,确定拟建工程的单位工程概算造价。
