The formwork is the suitable mold into which the concrete gets filled and sets to support horizontal and vertical members. However, constructing formwork comprises different steps and stages, each of which has peculiar conditions. For instance, safe construction of formwork involves shuttering pouring concrete and the eventual removal of the formwork. By the way, it can only be removed after the formwork has taken shape and the concrete is set and dry.

On the other hand, certain safety precautions should be set in place in erecting these formwork structures. So, in this article, we have decided to outline some of the full precautionary measures for safety with formwork.
Safety measures for installing formwork
- Installing formwork involves considering the kind of span, dead load and setting the right temperature for the mixed concrete. In addition, set the concrete and its strength following the safety factors of the materials for the formwork.
- Users should also carefully inspect the concrete and the formwork to ensure no cracks or excessive knots. In detecting any fracture or any such thing, it should be discarded right away to prevent any hazard.
- Ensure you understand the timber centring, which may sink any time you load it with concrete. Therefore, the right thing to do is a factor that allows the kind of design for consideration.
- In terms of the support, the vertical structure must have a suitable brace in the correct position. The strength is necessary to create formidable support with the formwork when it carries the load. Otherwise, the lack of stability in the formwork can lead to an accident for the construction project workers.
- The result must be carefully handled when combining the timber centring and tubular steel in the same formwork. You must take all the necessary protective precautions to ensure no unequal settlement of shuttering components under the load.
- Another critical step is to inspect the tubular steel centring of the formwork installation during the project. In addition, the components of this structure also carry pieces of evidence of excessive resting, kinks, dents, and at times, damaged welds that can be removed at will.
- In addition, all the broken and buckled members of the shuttering must be dutifully replaced in the structure
- You should check all the locking devices for their level of efficiency working. Meanwhile, you should also align the coupling fins with the frames, following the whole structural frame.
- After you set the components of the construction skeleton inside the assemblage of the structure, you should also adjust all the screws and nuts into their rightful places. At the same time, they must get to the highest reach of their form and be well-plumb.
- When you shutter the frames, you should also tie them together with all the required braces that make rigid struts. At the same time, you should also install the diagonal braces in their proper positions. This process also allows the frames to have the load-carrying capacity you expect from the cast concrete after removing the formwork.
- We recommend that you make all the connections with the suitable nuts and bolts
- Use high-quality nuts and bolts and, consequently, avoid all kinds of rusted or spoiled threaded nuts and bolts.
- In the centre, you will need a qualified engineer to describe the precise method for the layout process. And then, the work team should work efficiently to adhere to all the instructions by the professional to install and use the formwork
- One of the fundamental parts of construction projects, the condition and bearing capacity of the soil, must be carefully considered for the centring jobs. Click here to read about Plywood Formwork- the Advantages, Types and Applications.
- Another vital part of the construction is the weather condition of the environment, which must be dutifully considered. For instance, dry clay can become like plastic after a heavy rainfall, which means that there will be a show of marked decrease in the bearing capacity of the formwork.
- The props of formwork must be firm and stable to sit firmly in the soil. At the same time, it can bear the weight of the formwork, which takes the importance of the load on it.
- After setting the structures properly in the soil, you must ensure that no one disturbs it until it accomplishes the designated purpose.
- When installing formwork in a project, check out your drainage plans and set the proper one in place. For instance, you should drain away water from the washing of the formwork by rain, especially during the curing process of the concrete. This process will help to do away with the supporting soil strata.
- Carefully inspect and strengthen the centring, especially when pouring the concrete in its place
- It is also imperative to adjust all the screws to their optimum tightened level while all the wedges below the vertical supports are adjusted accordingly.
- You must also adequately protect and secure all the shuttering away from swinging loads and moving vehicles.
Checklist for formwork inspection after installation
When centring the formwork, you should also ensure that it has the following attributes to remain valid, efficient and reliable.
- Ensure that all the footings and the sills located under all centring posts must be perfect
- Plumb all the panels in both directions
- Lower adjustment wedges and screws must also be snug against the legs of the panels
- Make sure that the adjustment screws or the heads of jacks are in complete contact with the formwork in the project.
- The props should also be adequate for the transfer of the load to all the supporting points. Notably, this factor is necessary in the case of chajjas and balconies.
- Check to see if all the locking devices are in a secure and closed position while correctly placing all the cross braces
