下浮比例：建安工程造价税前下浮9%，其中发包人认质认价部分材料价差、按实计算费用、安全文明施工专项费用、安全文明施工按实计算费用、规费、税金不下浮。这句话该怎么样理解（定额计价）
人工价差和材料价差需要下浮吗
1.在预算书里点击“人材机汇总”把甲供材料勾选为“完全甲供”(参见截图1)。
2.点击“预算书设置”—预算书属性框里勾选即可(参见截图2)。
3.点击“费用汇总”将取费表按截图3所示进行设置即可.。
这三点正确设置后人工价差软件会自动按地区造价文件计取的。材料费按截图3设置后会自动扣除甲供材料费后进行让利的(也就是说甲供材料外的其他材料是需要让利的)。至于安全文明施工专项费用是在措施费里计取的其本身就不允许让利的(请参见截图4)。

就是结算工程造价=（套用定额全价-包人认质认价部分材料价差、安全文明施工专项费用、安全文明施工费用、规费、税金）*0.91
