Why Wouldn’t You Use Modular Slab Formwork Systems?

Modular slab formwork has been around for decades however surprisingly it is not in frequent use within smaller tier 2 and tier 3 concrete formwork contractors within Victoria. This brief article will highlight the benefits of using modular slab formwork as opposed to traditional methods for suspended slab formwork.

Conventional Slab Formwork/Falsework

Conventional Slab Formwork Construction

Modular Slab Formwork

Modular slab formwork can come in an array of forms, each of which has their merits. Lifeform formwork systems are considerably less labour intensive than conventional methods to set up and strip. They require plywood to be laid over the modular panel joists allowing for an excellent class of finish.

Slabform formwork systems allow for further labour savings as panels come prefabricated with plywood. Installation of both becomes systematic once the learning curve is passed which can then significantly increase efficiency.

A significant benefit that is perhaps not as well understood with contractors who are unfamiliar with modular formwork systems is the stripping advantages. Many of the more recent modular systems such as Liteform and Slabform incorporate drop heads with propping. Drop heads allow the beams and panels to be stripped. With a simple blow of a hammer, part of the drop head supporting the formwork beams ‘drops’.  The beams and panels can then be re-used on the next section while the props remains in place supporting the recently cast slab undisturbed.

This can often be done when the slab is said to become ‘self-supporting’ which could be as soon as 4 days. Note that this depends on a range of parameters such as design capacities, construction loads, slab depth, prop spacing and temperatures and so is project dependent.

The advantage with this stripping technique is that it is fast. The contractor does not have to carefully remove small amounts of formwork and re-prop (re-shore) to free up some shoring equipment. The procedure is safe and reliable. It allows the reuse of the beam and panel components for upper levels with additional propping. This has the potential to save on half the formwork equipment required for a multilevel structure when we consider the optimised propping and components used compared to conventional methods.

Further benefits become evident once the formwork system is in place. The optimised spacing of propping and beam capacities reduce congestion whilst in place. This depends on the depth of slab to be formed and construction load but can be as great as 3m X 1.5m, which caters for movement much more effectively than 1220×1524 or 1829 frame bays with cross bracing.

Reduced Congestion Under The Slab

Crane utilisation is significantly minimised when compared to using table forms with all components weighing less than 16kg and therefore capable of being installed and removed by hand. The formwork system requires only basic components including, propping, beams, panels, bracing and/or wall mounts to substitute majority of conventional frames, braces, base jacks, U-heads, bearers, joists and plywood.

Modular formwork systems can be braced assuming effective top restraint where fixings to the permanent structure are used to provide stability. In the event that this is unauthorised by the project engineers bracing between propping in strategic locations will provide stability and allow the falsework to support all the imposed lateral loads required.

Modular Slab Formwork Systems vs Conventional

With the aid of proprietary accessories, modular Slab formwork systems can easily accommodate infills around columns or handle complicated edges to match required project dimensions. They can also easily match in with other modular slab formwork systems or traditional methods where needed.

Modular Formwork Systems have a short learning curve, and when we consider the basic components and the systematic process that comes with repetition, they require less skill to install and the chance for error is greatly reduced. This is further magnified thanks to the reduction in labour due to the speed of assembly. Naturally Cassaform offers exceptional support and service to help you get up and running quickly.

For contractors who utilise their own conventional formwork equipment, trying a modular formwork system while their equipment is idle can be difficult to do. However, when you consider the cost saving associated with a reduction in the cost of labour and reduction in the purchase of Formply and other consumable items, the cost of using a conventional system is often significantly higher. This is more evident in multistorey/ repetitious structures.

Not fully understanding the formwork systems constraints and limitations combined with the perceived fear that it will ‘simply not work’ or that it is ‘too hard’ is creating a divide between formwork contractors. The information, support and service is there to help integrate these systems within our industry and for those who seek out and take up these innovative opportunities the rewards will come.

Good Back Propping Design By Temporary Works Engineers.

Temporary Works Engineers will design the best way of back propping a newly poured concrete slab. Back propping is used to support a suspended slab while the formwork is being stripped. The back propping then remains in place until the slab gains enough strength to support itself. It is a vitally important part of the safe and economic construction of in-situ concrete structures.

Benefits Of Back Propping

Within the construction industry, builders are constantly challenged with the growing need to improve the speed of the project. Before the formwork can be safely removed the concrete must be strong enough to avoid failure or undue cracking and deformation of the slab. For efficient slab construction, incorporating back propping in early striking of the concrete structure can enable the following key outcomes:-

  • Allowing the formwork to become available sooner for reuse, reducing the quantity of formwork required,
  • Gives earlier access for follow on trades and services to the supporting floors,
  • Allows building of the next level to commence sooner,
  • Provides savings in construction time while maintaining site safety and the performance of the concrete structure.

Temporary Works Engineers Design Considerations For Back Propping

The back propping design must take into account the critical loading condition. For a multi-storey build, this may not be when the formwork is struck and the slab becomes self-supporting. The design must ensure the supporting slab can support the weight of a freshly cast slab above.

An Example Of A Back Propping Design By Temporary Works Engineers

With the rapid improvement of technology, the time involved in design has reduced dramatically. Temporary works engineers can now analyze multiple factors to produce an efficient design. They can not only help in solving engineering solutions, but can provide efficient, cost effective solutions.

Whether you’re a formworker, builder, developer, or a specialized contractor, back propping with the help of a temporary works engineer can provide cost / time effective solutions and guarantees peace of mind from an independent review.

Cassaform Helps Build Brighton Kindergarten

This particular builder needed a formwork supplier with experience in suspended slabs and came to us a few weeks ago with a construction drawing of a kindergarten project they were about to commence in Brighton Victoria.

Cassaform Formwork is used to build a new kindergarten in Brighton, Vic

Cassaform helps build new Brighton kindergarten.

Using the structural & architectural drawings provided, our in-house Cassaform formwork specialist estimated the quantities of formwork frames, braces, base jacks and head jacks required to form the suspended slab and provided the client with a detailed written quote for the job.

Upon completion of the Engineering design and within days of placing the order all the equipment required to form the suspended slab was rigorously inspected and verified ready for hire and delivered to site. With no time to waste construction of the suspended slab was immediately commenced.

Upon visiting the site only a few days later, to check on how things were going, we were literally amazed to see how much they had formed in just a few short days. As you would expect from a well organised builder like this they have already placed a forward order with us for No 3 Cassaform Acrow props to back prop the slab when the false work has been stripped from the site.

A real credit to this builder for wasting no time getting stuck right into the project.
