Plastic formwork is a relatively new product that is not yet widely promoted in the construction industry. However, many organizations and governments are vigorously advocating for this green product, and some have even made its use mandatory. Regardless of how it is promoted, what builders care about is still how to do more with lower costs, that is, reducing expenses. In addition to protecting the environment, one of the major advantages of plastic formwork is its number of uses; the more it is used, the more costs can be saved. Now, let’s discuss how to save 50% on costs by using plastic formwork. A previous case study was the Guanhua International Project by China State Construction Engineering Corporation in Zhengzhou. At the time of signing the contract, the budget was over 3 million yuan, which was based on the budget for wooden formwork. After the upper floors were capped, only a little over 1 million yuan was used, resulting in a budget savings of more than 50%. To save costs, it is crucial that the product meets standards. If the product does not meet the standards and only stays within budget, then there is no hope of saving costs; you might as well stick to using wooden formwork. Another key point is construction site management. Since plastic formwork is a new product, some carpenters have never used it, and compared to wooden formwork, plastic formwork may be a bit heavier, which workers may be reluctant to use. If they are not keen on it, they may express resistance and claim the product is not good, and we have encountered such issues before. Sounds familiar? When wooden formwork was being promoted, similar situations occurred. The promotion of new products will inevitably go through a transition period, but this is a trend that cannot be reversed. If the construction site insists on using it, they will have no issues. Another major problem is waste, which is also related to construction management. Sometimes, plastic formwork that could still be used is discarded because workers would rather use new boards. This can lead to significant waste. The management method of China State Construction Engineering Corporation is very effective; they allow two buildings to use plastic formwork simultaneously and then compare which side has more waste. If there is a large discrepancy, it indicates that one side is not doing well, and the labor can be addressed accordingly to see how to handle the situation. Having this comparison encourages workers to be more careful during use, as they will be concerned about wasting material. As a result, after completing both buildings, the cost savings reached over 50%. Many people often ask me how many times plastic formwork can be reused. This is a difficult question to answer because the number of cycles is directly related to the construction team's handling. If used normally, it is certainly not a problem to achieve 30 uses, and some can even reach 50; it all depends on how you use it. However, if it is tossed around carelessly, how can I guarantee that? Therefore, the premise of 30 cycles is that it must be subject to normal wear and tear, not reckless waste.
