Plastic formwork is a relatively new product, and its promotion in the construction industry may not yet be very widespread. However, many organizations and governments are vigorously promoting this green product, and some have even made its use mandatory. Regardless of the promotion, what builders care about is how to accomplish more tasks at a lower price, that is, to reduce costs. In addition to protecting the environment, a major advantage of plastic formwork is its number of cycles. The more times it is used, the more costs can be saved. So how can using plastic formwork save 50% of costs? A previous case was the Zhengzhou China State Construction Seventh Engineering Division's View Lake International Project. At the time of signing the contract, the budget was over 3 million, which was based on the budget for wooden formwork. After the top floor was capped, only over 1 million was used, achieving a **budget savings of over 50%**. To save costs, one key point is that the product must be up to standard. If the product does not meet standards, as long as it does not exceed the budget, then there is no hope of saving costs; one might as well use wooden formwork honestly. Secondly, construction site management is crucial. Since plastic formwork is a new product, some carpenters may not have used it before, and compared to wooden formwork, plastic formwork may be a bit heavier, which workers might not prefer. If they dislike using it, they may develop resistance and say various negative things about the product. We have encountered these issues, and doesn’t this sound familiar? When wooden formwork was being promoted, similar situations occurred. The promotion of new products inevitably involves a transition period, but this is an unstoppable trend. If the construction site insists on using it, they will eventually have no issues. Another significant issue is waste, which is also related to construction management. Sometimes, even when some plastic formwork can still be used, workers may prefer to use new boards instead of old ones, resulting in significant waste. However, the management method of China State Construction Seventh Engineering Division is excellent. They let two buildings use plastic formwork simultaneously and then compare which side has more waste. If there is a significant difference, it indicates that one side is not managing well, and this situation can directly lead to discussions with labor services to see how to address it. With this comparison, workers become more cautious in their usage, worrying about excessive waste. This way, the cost savings for both buildings can exceed 50%. Many people often ask me how many times plastic formwork can be reused. This question is actually difficult for me to answer because the number of cycles is directly related to the construction team's usage. If used normally and worn out, 30 uses is definitely not a problem; there are even cases of 50 uses, depending on how it is handled. If it is carelessly discarded or dropped, how can I guarantee that? Therefore, the premise for achieving 30 cycles is that it must be used normally and not wasted recklessly.
