问题 单项选择题

某分项工程工作计划在第4、5、6周施工,每周计划完成工程量1000m3,计划单价为20元/m3;实际该分项工程于第4、5、6、7周完成,每周完成工程量750m3,第4、5周的实际单价为22元,第6、7周的实际单价为25元。则第6周末该分项工程的进度偏差和投资偏差分别为( )元。

A.-15000,-6750
B.-6750,15000
C.15000,6750
D.-15000,6750

答案

参考答案:C

解析: 投资偏差=已完工程实际投资-已完工程计划投资=实际工程量×(实际单价-计划单价),进度偏差=拟完工程计划投资-已完工程计划投资=(拟完工程量-实际工程量)×计划单价。对于该题投资偏差分两部分:第4、5周的投资偏差=750×2×(22-20)=3000;第6周的投资偏差=750×(25-20)=3750,所以总投资偏差=3000+3750=6750。该题进度偏差分两部分:第4、5周的进度偏差=(1000×2-750×2)×20=10000;第6周的进度偏差=(1000-750)×20=5000,所以总的进度偏差为10000+5000=15000。
