我们通过微信进行交流，在假定设计标准和质量要求相同的前提下，对比两种施

We communicate through WeChat, and on the premise of assuming that the design standards and quality requirements are the same, compare the construction cost of the construction drawings under the two construction methods as follows: <br><br>3# building assembly design and cast-in-situ design cost comparison <br> <br><br>from the above table can be seen, the same For residential buildings, the cost of prefabricated square meter construction and installation is 783.94 yuan lower than the cost of cast-in-place design square meter construction and installation, of which, civil engineering is 811.71 yuan higher. It is not difficult to find that the difference in cost between the two construction methods is mainly concentrated on civil engineering.

We communicate through WeChat, assuming that the design standards and quality requirements are the same, compare the budget cost of the construction drawings under the two construction methods as follows:<br><br>Comparison of the design of assembly type and the cost of watering design<br> <br>As can be seen from the above table, the same residential building, assembly-type design square meters of construction and security costs than the current watering design square meters construction costs lower than 783.94 yuan, of which, civil works higher than 811.71 yuan. It is not difficult to find that the cost difference between the two construction methods is mainly concentrated in civil engineering.

We communicate through wechat, and under the premise of the same design standards and quality requirements, the budget cost of construction drawings under the two construction methods is compared as follows:<br>Cost comparison between prefabricated design and cast-in-place design of 3-storey building<br>It can be seen from the above table that the construction and installation cost per square meter of prefabricated design is 783.94 yuan lower than that of cast-in-place design square meter for the same residential building, of which, the civil engineering cost is 811.71 yuan higher. It is not difficult to find that the cost difference between the two construction methods is mainly concentrated in the civil engineering.<br>
