Casting errors during the structural phase of a project, known as ‘site cast element’ mistakes, can lead to substantial rework expenses. These costs are avoidable through the implementation of advanced technological tools. By conducting meticulous formwork inspections, you can significantly mitigate project risk

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%.

Throughout both inspections the ACERTA’s team proved that CHECKTOBUILD’s C2B Platform definitely offers results with the same accuracy level as other traditional “reality capture” techniques with the advantage of reduced time to obtain results and take decisions.
Since in the two inspections of similar elements, the use of formwork was necessary, it was concluded that in the case of the second inspection, when the operation was carried out after the pouring, deviations were incurred in the concrete that could have been corrected in advance. As verified in the first inspection case; where the inspection was carried out on the formwork and only 70% of the concrete had been poured, That, allowed the team to verify the correct alignment of the formwork to the model.
