Important Considerations in Formwork and Concreting Works

21 June 2023

Formwork and concreting are vital components of the building process, and when done right, they make it simple and risk-free for workers to pour concrete and establish their foundation. Nevertheless, if the formwork for your next project is dangerous, improperly supported, or constructed incorrectly, it might end in tragedy. Building a permanent foundation or structure from concrete requires formwork, which is only a transitory structure. The formwork construction must align with the current designs since the concrete can be poured horizontally or vertically. When it comes to utilising formwork for concrete, there are a few significant pitfalls that you absolutely must stay away from.

Sufficiency of Support

While setting up scaffolding for a vertical pour of concrete, the worst thing you could do would be to misjudge how heavy the concrete would be once it is completed setting up. Your formwork might become nothing more than a leaky pile of metal if sufficient bracing and support are not provided. This could result in damage to the structures that are in the area as well as possible risks for the employees. Be sure that the barricading you employ can support a load equal to or greater than the volume of concrete being poured.

Concrete Pouring

When the concreters arrive to pour their concrete, they need to ensure that any element of your formwork structure they pour over is either removed by you or moved out of the way. It is of the utmost importance that you construct scaffolding to a suitable height for the employees and provide them with the appropriate safety gear. As you put up your formwork and concreting, you mustensure enough safe room for the workers and the equipment to move around.

Removing the Formwork

As soon as the strip is ready, ensure your scaffolders start at the top and work their way down. They are not allowed to remove the bracing holding the exterior formwork until you have provided them with additional support to bring the formwork to the ground securely. Before you can put the formwork back onto trucks, you mustensure that it is stacked in a secure area that is distant from any foot traffic.

Movement And Vibration

The movement of your formwork will occur as a result of pouring concrete. This excessive vibration has the potential to dislodge any bracing or materials that have been improperly installed. Be sure that your build accounts for such movement and that you have a response in place.

Planning

Ensure you adhere to the architect’s plans to the letter to get the desired result for the project they are designing. The architect will have drawn detailed designs of how the construction will ultimately appear. Please do not attempt to enhance or alter their blueprints to accommodate your formwork. You have to ensure that your formwork is compatible with their ideas from the beginning to the end.

Materials

The materials used for formwork and concreting works should be selected based on their strength, durability, and suitability. Factors such as weather conditions, the size and shape of the structure, and the type of concrete being used should all be considered when selecting materials.

Timing

Timing is critical when it comes to formwork and concreting works. The concrete should be poured at the right time to ensure it sets properly and does not crack or deform.

Quality Control

Quality control measures should be in place to ensure that the formwork and concreting works are up to standard. Regular inspections, testing, and documentation can help identify any issues early on and ensure they are addressed promptly.

Choose the appropriate materials as the final step. Formwork and concreting may be constructed from various materials; thus, you must select the most appropriate construction.
