问题 问答题 案例分析题

背景:

某六层单元式住宅共54户,建筑面积为3949.62㎡。原设计方案为砖混结构,内、外墙为240mm砖墙。现拟定的新方案为内浇外砌结构,外墙做法不变,内墙采用C20混凝土浇筑。新方案内横墙厚为140mm,内纵墙厚为160mm,其他部位的做法、选材及建筑标准与原方案相同。

两方案各项指标见表2-1。

设计方案指标对比表

表2-1

问题:

1.请计算两方案如下技术经济指标:

(1)两方案建筑面积、使用面积单方造价各多少?每平方米差价多少?

(2)新方案每户增加使用面积多少平方米?多投入多少元?

2.若作为商品房,按使用面积单方售价5647.96元出售,两方案的总售价相差多少?

3.若作为商品房,按建筑面积单方售价4000元出售,两方案折合使用面积单方售价各为多少元?相差多少?

答案

参考答案:

(1)两方案的建筑面积、使用面积单方造价及每平方米差价见表

 

可知,按单方建筑面积计算,新方案比原方案每平方米高出34.57元,约高3.28%;而按单方使用面积计算,新方案则比原方案高出3.59元,约高0.24%。

(2)每户平均增加的使用面积为:(2881.98-2797.20)/54=1.57㎡

每户多投入:(4300342-4163789)/54=2528.76元

折合每平方米使用面积单价为:2528.76/1.57=1610.68元/㎡

计算结构是每户增加使用面积1.57㎡,每户多投入2528.76元。

问题2:

解:若作为商品房按使用面积单方售价5647.96元出售,则

总销售差价=2881.98×5647.96-2797.20×5647.96=478834元

总销售额差率=478834/(2797.20×5647.96)=3.03%

问题3:

解:若作为商品房按建筑面积单方售价4000元出售,则两方案的总售价均为:3949.62×4000=15798480元

折合成使用面积单方售价:

砖混结构方案:单方售价=15798480/2797.20=5647.96元/㎡

内浇外砌结构方案:单方售价=15798480/2881.98=5481.81元/㎡

在保持销售总额不变的前提下,按使用面积计算,两方案

单方售价差额=5647.96-5481.81=166.15元/㎡

单方售价差率=166.15/5647.96=2.94%

 

解析:本案例主要考核利用技术经济指标对设计方案进行比较和评价,要求能准确计算各项指标值,并能根据评价指标进行设计方案的分析比较。
