During a routine inspection of the structural ground beams on a pharmaceutical project, an error was identified in the placement of two concrete beams.
The beams were identified to be off by 60 millimeters (2.3 inches).The XYZ Field Application Engineer (FAE) identified that the rebar and formwork were in the incorrect position and would have continued that line for half of the ground beams.
By identifying this error at the point of rebar installation, instead of at a later stage, the issue was rectified before the concrete pour, saving valuable time and material costs. In this particular pharmaceutical project, the margin for error was tight, as the outside of the beams are crucial for positioning the external façade of the building. The secondary steel sits on top of the beams and a deviation of 60 millimeters is far too much, with an allowable tolerance of only 10 millimeters (0.39 inches).
The incorrect placement of two ground beams would have caused logistical issues with the schedule and underground pipe placement had it not been for XYZ’s early intervention. Identifying the error early on prevented it from becoming a bigger issue throughout the entire building.
To correct the issue, extra reinforcing had to be added, then the concrete was poured on the outside to fill the gap.
