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。
