【问题】
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3（1）该工程的开工预付款是多少？
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3 （2）该工程的保留金是多少？
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3（3）监理工程师每月实际应签发的金额是多少？
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3 （4）分析各月的投资偏差是多少？总投资偏差是多少？
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3【参考答案】
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3合同价款=20000×100=200(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ31．工程开工预付款=200×20%=40(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ32．工程保留金=200×5%=10(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ33．第一个月应签工程款=3000×100×（1-10%）=27(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3由于合同规定月度付款证书最低金额为50万元，故本月监理工程师不签发付款证书。
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3第二个月应签工程款=5000×100×(1-10%)×110%=49.5(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3实际签发工程款=27+49.5=76.5(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3第三个月应签发工程款=8000×100×120%=96(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3实际签发工程款=96-40×40%-(10-3-5.5)=78.5(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3第四个月：累计计划工程量为20000㎡，累计实际工程量24000㎡，因为（24000-20000/20000）×100%=20%>15%，
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3所以第四个月支付工程款时应进行单价调整。
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3超过计划15%工程量为：
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ324000-20000×15%=1000(㎡)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3调整后单价为：100×0.9=90(元/㎡)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3应签金额=[(8000-1000)×100+1000×90]×120%=94.8(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ3实签金额=94.8-40×60%=70.8(万元)
ÃýIγ±ãBfpbbs.3c3t.comÔùY#dçÛ34．各月投资偏差如下表所示。
