Cassaform’s modular formwork systems are designed in compliance with the highest safety standards and can be easily integrated in to any type of worksite. Thanks to the modularity of the elements, our systems have been designed to allow quick handling / dismantling on-site leading to fast and efficient forming. Using a formwork system can significantly reduce timber wastage on site when compared to conventional forming methods.
Modular Formwork Systems
From small commercial projects right through to large scale civil engineering projects, our systems are great for:-
- Slabs and beams
- Lift shafts and stair towers
- Abutments and Piers
- Bridges and Tunnels
- Climbing Systems
For the projects that are better suited to conventional methods, we also specialize in formwork frame hire, formwork equipment and formwork supplies. With competitive concrete formwork hire rates, a comprehensive range of formwork systems available and experienced engineering staff, Cassaform can work with you to ensure that you have the best solution for your formwork hire needs.
What is Formwork?
Formwork is the terminology used to describe the material required to shape or mold concrete structures prior to curing.
It can be permanent such as lost formwork which is cast into the slab soffit or each side of insitu walls or it can be temporary. Temporary formwork predominantly consists of a plywood or plastic sheet, reinforced by conventional timbers or modular aluminum type systems. Depending on the class of finished required and the formwork system adopted, formwork liners are also being incorporated to enhance the concrete finish.
Formwork is supported by falsework or shoring which usually consists of timber, aluminum or steel sections. Given the volumes of gear required and shorter project durations it may be feasible to consider formwork hire as an alternative to purchase.
Cassaform offers a fully engineered formwork service.
- This service begins with contacting our customer service center on 1300745674. Our Customer Service representatives will handle all repeat orders and general transport scheduling enquiries.
- For more complex project requirements your contact details will be recorded and you will be transferred to you an Account Manager.
- Your Account Manager will discuss your project requirements with you over the telephone and then may arrange a site inspection or meeting to discuss the project in more detail.
- In order for Cassaform to prepare written proposals AutoCAD or PDF drawings will be required.
- Construction Drawings are forwarded to our In-House Engineering department who will then prepare preliminary concept drawings and written proposals.
- More complex projects may require further meetings with our engineers for construction concepts to be refined and accepted prior to proposals being finalized.
- Upon acceptance of the conceptual drawings and proposal, our Engineering Department will finalise designs, prepare construction issue drawings and accurately determine detailed equipment requirements.
- Equipment is procured and prepared by the Customer Service & Operations Department to meet your program requirements
- Your Account Manager will keep in regular contact with you in order to schedule delivery. Note – Delivery can be arranged by the client if preferred or we can be made of your behalf if preferred.
- Upon delivery, the Account Manager or Engineer will visit site on a regular basis to offer assistance and support throughout the project duration.
- If engineering sign off is required before concrete pours this can be arranged.
There are a number of different materials and systems used to form concrete structures. Depending on the complexity and arrangement of the structure a contractor has to identify which will be the most favorable for the given application.
Below are just a few methods and applications for vertical and horizontal forms.
- Conventional timber
- Double sided wall formwork
- Single sided wall formwork
- Modular formwork (lightweight & Steel)
- Permanent polymer type forms
- Conventional timber
- Aluminum panel type systems
- Aluminum beam-panel systems
- Permanent steel tray type forms
At Cassaform we analyze your project and in consultation help you the contractor by providing sound advice on all your formwork hire needs.
Benefits of Cassaform formwork over Traditional ways of formwork.
Traditionally formwork used to cast either vertical or horizontal concrete elements consists of timber bearers, joist and formply lining to give concrete its smooth or textured finish. This traditional method of assembling formwork is very slow and very labour intensive. To meet the cycle times of the construction program, formworkers resort to putting on extra labour to achieve the end result. They then resort to fabricating formwork tables to speed up their process and also rely on the fact they have the ability of reuse the timbers and formply components across a few projects to amortise their costs.
This philosophy is now dramatically changing as formworkers are now better understanding hidden costs to their business. For example
- Timber and formply material wastage costs.
- Storage facilities required to house idle building materials and formwork tables between projects.
- The suitability of their owned equipment to suit every project.
- Labour costs incurred to clean, repair and handle conventional formwork systems.
- Costs associated with stock control, management and accounting / depreciation of owned equipment.
- Rented equipment can be fully expensed to the project.
Modular systems provided by Cassaform on the other hand can provide up to and in some cases even over 50% labour and time savings to your project. These systems are available for rental or sale.
There are variety of modular systems available in the market. Some are suited to casting vertical concrete elements such as walls and stair or lift cores and others are suited to casting horizontal concrete elements like suspended slabs.
In the case of modular walling systems, as the name suggests the systems consist of a series of modular panels of varying sizes which can be joined together quickly and easily to fit the desired shape to be cast. These panels typically come in heights of 3.0m, 1.5m or 1.0m and varying from 200mm up to 1000mm in width but can be joined to achieve wall heights of up to 9.0m. They can be assembled and positioned either horizontally or vertically to best suit the final shape required. They are extremely versatile and can be joined together or dismantled with clamps with the aid of a simple hammer. To put this into perspective a typical wall where say 6 men would be required for a total of 5 days to assemble a conventional formwork wall, this can be achieved in less than one day with three men using a modular walling panel systems.
In the case of modular slab systems there are a few different types of systems available but irrespective of which system is used, they are generally much faster and easier to use compared to conventional formwork systems. For example using an aluminum slab panel system 3 men can erect approximately 500m2 in one day whereas the same area formed using conventional systems with timber bearers, joist and formply could 6 men up to 4-5 days to complete.
Due to the modular nature of these systems they are light and easy to assemble and fit most flat plate slab areas. The primary components consist of beams, props and panels. The panels come in various sizes and consist of an aluminum frame with formply inserts.
These modular slab systems have a built in drop head mechanism which allows the aluminum beams and panels to be removed earlier than the shoring props. This allows reuse on the beams and panels which can be used to form subsequent floors. Apart from significantly saving in the cost of equipment required to service a project, it has a significant labour savings benefit by eliminating the need to remove formwork shoring and re-shore or back prop.
In Australia there is a real shortage of skilled labour and skilled sub-contractors. Modular systems whether it be for walls or slabs reduces the requirement to have such skills on projects as the systems are easy to assemble and the manufacturer or supplier will generally provide you with construction drawings as to how it is to be assembled.
What is formwork shoring?
Formwork Shoring is a word also used in the construction to describe the temporary support structure used under formwork to support freshly placed concrete in multi-story construction work. Construction loads are usually the maximum loads that multi-story structural floors will experience in their entire service life. Therefore shoring and reshoring is provided for an adequate number of floors below to distribute the construction loads in such a way that the loads imposed are within the design strength capacities of the floors below without causing excessive stress, deflection or cracking.
