Casting errors during the structural phase, also known as “site cast element” mistakes, can result in substantial rework expenses. These errors are often caused by misaligned formwork, leading to deviations from the design. Fortunately, these costly mistakes are avoidable through the adoption of advanced technological tools. Implementing thorough formwork inspections can significantly reduce project risks and improve accuracy.

At the moment of the operation the element’s concrete wasn’t completely poured. Thus, the system was able to confirm the formwork alignment on the constructed element and the remaining part to pour.

• The system has made a very good comparison of the stairs in formwork, without having finished pouring all the concrete. Actually, it is evident that the edges of the steps are detected as being part of the formwork and not the model, but the already poured concrete is perfectly flat.
• Something similar happens around the side corners of the stairs, where we can observe that the biggest difference between the point cloud and model is in the protruding formwork elements, nevertheless the percentage estimated to be inside of tolerance (which we call “Similarity Percentage”) is of around 97%.

The inspections demonstrated that CHECKTOBUILD’s C2B Platform offers the same accuracy as traditional reality capture techniques while significantly reducing the time needed for analysis and decision-making.

• First Inspection: Allowed the team to correct formwork alignment before pouring, ensuring the structure met the design specifications.
• Second Inspection: Highlighted the cost and time implications of uncorrected deviations, which could have been avoided with earlier inspections.

Key takeaway: Early formwork inspections using the C2B Platform lead to higher accuracy, fewer errors, and optimized project costs. Advanced technology like this is essential for improving construction quality and reducing risk in modern projects.
