某项目周转使用临时设施建筑面积100m2，每平方米造价100元，使用年限4年，利用率90%，工期50天，一次性拆除费500元；该项目一次性使用临时设施建筑面积200m2，每平方米造价50元，残值率5%，一次性拆除费300元，其他临时设施所占比例10%，则该项目临时设施费总额为______元。
A．880.52
B．9800
C．10680.52
D．11748.57
参考答案：D
解析： 临时设施费的计算公式为：临时设施费=(周转使用临建费+一次性使用临建费)×[1+其他临时设施所占比例(%)]。其中，周转使用临建费=∑{临建面积×每平方米造价/[使用年限×365×利用率(%)]×工期(天)}+一次性拆除费；一次性使用临建费=∑{临建面积×每平方米造价×[1-残值率(%)]}。
则临时设施费={[(100×100)/(4×365×90%)]×50+500+[200×50×(1-5%)+300]}×(1+10%)=11748.57(元)。
