1.(1)管道工程量:
①低压碳钢管D89×4:(1.2-0.12)×2=2.16(m)
②低压碳钢管D159×5:(1.2-0.12)×2=2.16(m)
③低压碳钢管D219×6:(4.7-1.5)×2+(0.3+0.3)×2+(0.85×2+1.2×3)=12.90(m)
④中压碳钢管D89×6:
(0.3+2.9+1.2-0.12)×2+(4.7-1.5)×3+(0.3+0.3+1.2)+0.3+2.4+0.85+1.2=24.71(m)
⑤中压碳钢管D159×8.5:(1.2-0.12)×2+(0.75+1.5+0.75)+(2.4+0.85+1.2)×2=14.06(m)
⑥中压碳钢管D219×9:0.75×4+1.5+0.3+0.4=5.20(m)
(2)阀门工程量:
①低压法兰阀门安装J41H-16截止阀D89×4:2个
②低压法兰阀门安装J41H-16截止阀D159×5:2个
③低压法兰阀门安装J41H-16截止阀D219×6:2个
④中压法兰阀门安装J41H-40截止阀D89×6:4个
⑤中压法兰阀门安装J41H-40截止阀D159×8.5:3个
⑥中压法兰阀门安装H41H-40止回阀D89×6:2个;
⑦中压法兰阀门安装H41H-40止回阀D159×8.5:2个
2.分部分项工程和单价措施项目清单与计价表,见下表:
3.综合单价分析表,见下表:
4.(本小问按税法改革前的做法解题,仅供参考)
①含增值税综合单价=(38+30+25+38×100%)×(1+11%)=145.41(元)。
②增值税应纳税额=(38+30+25+38×100%)×11%-(30×17%+25×15%+38×5%)=3.66(元)。
