Prefab forming systems have been receiving much recognition in the industry and their application became more widespread as of late. They are seen as a cost-efficient and flexible tool for handling complex forming and building tasks.
Indeed, concrete and steel framework solutions are becoming more and more versatile, allowing architects to rethink the use of cast-in-place concrete. This novelty is utilized as a structural element and for architectural purposes. You could say that fabricated forming systems are an integral part, the driving force of the dynamic construction evolution.
Prefab forming systems have pushed the boundaries of what is possible and feasible. The components can be assembled for almost any size or shape. What is more, they have reduced the need for on-site skilled labor and enabled the reuse of forms as individual units and large sections.
Considering all the aforementioned benefits, it is surprising that contractors are slow to embrace this trend. Namely, it is estimated that only three in five contractors take advantage of prefab systems. It seems that many of them are cautious when it comes to working with factory-built components. Others are not eager to cover the still high cost of prefab framework and the expensive freights.
As for this latter issue, we must point out, again, that prefab concrete and steel framework systemslet contractors save money in the area of labor cost and also capitalize on the reuse value. As a result, most contractors should be able to accomplish lower expenses per use.
Using a permanent steel formwork, for instance, you can reduce the costs and work time by 50%, compared to using conventional solutions like timber hobs.
Upon ordering a prefab system, what the contractor receives is the complete package. The rented or purchased shipment includes all the necessary hardware, fillers, corners, accessories and pilaster forms.
At first glance, things may seem complicated because there are so many pieces. However, each and every single one fulfills a specific purpose.
Furthermore, most formwork connections are made with one type of hardware. In fact, the whole system is built around it and the amount of nailing and protruding rusty elements is minimal. This means that fewer people can handle the material, and they can do it safely.
Erection is a breeze compared to some traditional solutions and it can be carried out even by unskilled workers. Assembly plays out nice and easy as well because sizes are indicated and prepared layouts are already furnished for the task at hand. Of course, this implies very little nailing and drilling, except for activities such as reinforcing bars.
The process can be further streamlined in case the contractors make requests regarding the development and availability of certain items.
A small job, such as setting up the foundations for a house or a store is a great chance to try out prefab systems and see whether it works for you and your workmen. However, note that they are likely to perform well in all sorts of jobs because they are pre-engineered and precision-made.
One thing to note is that prefab systems, like all others, call for proper maintenance. This goes a long way towards increasing their lifespan and protecting the concrete finish. The good news is that the forms can be cleaned and oiled easily using simple tools like a wire brush, a putty knife, a broom, a roller, and a sprayer.
Finally, make sure to adhere to best practices such as the optimal rate of placing. Doing so prevents any issues that can occur due to poor assembly, deflection being perhaps the most common one.
Although not all contractors are awakened to them, there are many advantages to using prefab forming systems. They are heavy-duty, yet simple to use. They are low maintenance and last longer. These pros certainly outweigh the cons, which, however, is not to say that these forming systems are a one-size-fits-all solution.
So, weigh your options and start with smaller-scale projects. Know that this is your chance to build smarter, easier, and faster, as well as produce higher quality end products.
