Is the PC structure expensive?

The prefabricated concrete structure is a concrete structure assembled from precast concrete components through reliable connections. That is, the pure PC structure.

At present, the big problem encountered by the industry in advancing PC construction is "high cost." This is a fact, and it may be a false claim.

The cost structure of PC building is obviously different from that of cast-in-place structure. This process is essentially different from the traditional in-situ casting process. Depending on the construction process, the performance and quality of the building will also vary. The "costs" of the two are incomparable. The construction field is constantly innovating in technology and craftsmanship. There are only two goals: to improve building performance under the same cost conditions, or to reduce costs under the same building performance conditions. Of course, if a new process can reduce costs and improve building quality, it is of course better, but it should not be too ideal.

Developers are very sensitive to "cost". Out of cost considerations, in order to achieve the goal of cost control and new process ideas that require "low cost", they must look forward and backward when making decisions, and repeat calculations. Subsidies are not enough to offset the increase in costs, resulting in developers seldom actively adopting PC buildings. This is completely understandable. The author believes that the technology is immature and the cost is high at this stage. As long as the offline government achieves the goal of compulsory PC, there is no need to be so active.

Putting it on a more macroscopic thinking dimension, cost is just a factor and one point to be considered. From an overall point of view, from an overall point of view, in the long run, in the future, in order to achieve green, environmental protection, low carbon, and improve building quality, it is acceptable to increase costs appropriately. With the continuous advancement of PC technology, the cost will gradually drop.

PC standardization can be used for the design and production of standardized components for assembly buildings. The "Modular Coordination Principle Standard" was completed for the first time in the industrialization of buildings. Only in this way can PC costs be reduced. The non-standardization of PC components in my country is a major obstacle to the promotion of prefabricated parts. Guangxi Steel Structure Engineering
