Stop paying for "second plastering" and "waste disposal": Lifecycle Cost (LCC) calculation of metal formwork

During the engineering cost estimation stage, the most common pitfall for general contractors is to focus solely on the "unit purchase price per square meter of the template" listed on the first quotation sheet. However, industry data shows that the template work typically accounts for 25% to 35% of the total cost of concrete structure projects, and it also drives up the labor volume by 40% to 50% of the total labor force. This set of data reveals a harsh truth: The template is not merely an auxiliary material; it is the core production tool that determines the labor, project duration, and profit of the project.

In markets with extremely high labor and compliance costs (such as Australia), the money saved on purchasing wooden templates at the beginning will eventually be compensated to the plasterers, repair materials, and landfill sites at several times the original cost in the later stages of construction.

The common wooden templates or ordinary plywood used in construction often result in wave-like, bulging, honeycomb-like, rough surfaces, or even severe tearing of the surface layer after removal. To meet the delivery standards of the clients, builders are forced to introduce an extremely expensive process: secondary plastering.

In the Australian market, this is an extremely costly OPEX (operating expenditure). According to the latest industry data from 2026, the average hourly wage of plasterers in Australia is as high as $77 AUD, and even experienced workers earn over $105 AUD per hour. If calculated by area, the cost of wet plastering for the walls is usually between $45 and $90 AUD per square meter. This means that if you use easily deformed wooden templates, not only will you delay the entry time of the next process, but you will also end up spending several dozen Australian dollars more per square meter on repairs.

Many builders believe that uneven walls are a sign of "poor workmanship" by the workers, but this is actually an inevitable result determined by the underlying material science:

1. Strong alkali corrosion and physical adhesion: Unset wet concrete is strongly alkaline (pH 12-13.5). When wood absorbs water, its surface fibers expand, and under heavy pressure, the concrete slurry will deeply embed into the wood fibers. During violent removal of formwork, the "adhesion" between the two will directly tear off the concrete surface layer, leaving deep and irreparable pits.

2. The illusion of film-faced plywood: The painted wood molds or film-faced plywood on the market attempt to solve the problem with a layer of phenolic resin isolation film. But this is merely a "band-aid" solution. During the pouring process, the intense friction of the coarse concrete aggregates (stones) combined with strong alkali corrosion usually destroys this protective film after 3 to 5 turnovers. Once the wooden base is exposed, severe adhesion and deflection deformation (bulging of the formwork) will recur.

To completely eliminate the problem of secondary plastering, it is necessary to upgrade the underlying logic of the materials. For example, using high-strength metal templates, which have absolute waterproof properties, extremely strong rigidity, and certain resistance to alkaline corrosion of concrete. The core technology also includes the accompanying flat tie system (Flat Tie System). The tie system locks the two sides of the templates firmly at the designed thickness from the inside, completely eliminating the uncertainty of traditional wooden molds relying on workers' experience to adjust screws. It can withstand huge lateral pressure of fluids and ensure that the wall is formed precisely without any deviation. When the metal templates are removed, a dense and smooth surface of fair-faced concrete will be obtained. For the general contractor, this means that dismantling the formwork results in the completion of the project. The time-consuming and costly secondary plastering process is completely eliminated, and the project cycle is significantly shortened.

In addition, environmental compliance and waste disposal are significant financial black holes that are often overlooked by many construction companies. For instance, in Australia, construction and demolition waste (C&D Waste) is strictly regulated. Taking Queensland as an example, the government imposes a high Waste Levy on construction waste sent to landfills (in the 2024-2025 fiscal year, the basic tax alone has exceeded $75 AUD per ton, not including the entrance fees at the processing plant and transportation costs). After only a few uses, wooden formwork becomes a heavy "negative asset" and construction companies have to spend a lot of money to dispose of it as garbage. However, the business logic of metal formwork is completely opposite: it is a recyclable asset. Metal formwork can achieve high-frequency turnover hundreds of times, reducing the cost-per-pour to an extremely low level; more importantly, when it reaches the physical lifespan limit, it will not become garbage that needs to be paid for to be processed. Construction companies can sell it as scrap metal and obtain a considerable residual value recovery (Scrap Asset Value).

In fact, true cost control is not about purchasing the cheapest one-time form, but rather eliminating those expenditures that do not create value: cutting the $50 per square meter plastering fee, and eliminating the high construction waste disposal tax. Facing the increasingly severe shortage of labor and compliance costs, upgrading the metal formwork system has become an inevitable choice in the high-paying market.
