Inspection case study

Design Deviation

During a standard inspection, XYZ Reality discovered that a fan coil unit in the building's ventilation system was found to be installed 1.5 meters away from the designated position of the approved 3D model. We were able to determine that the error resulted from the subcontractor failing to refer to the design information provided by the contractor.

If undetected, this error would have caused major clashes with electrical tray installations. The issue might have been concealed by subsequent work, only revealing its full, disastrous impact later, when it was too late, necessitating costly rework, impacting the budget and schedule.

Immediate Corrective Action

Upon XYZ’s discovery of the misalignment, the error was quickly reported to the electrical subcontractor, who then escalated the issue to the main contractor. XYZ collaborated and discussed the issue with the teams and the necessary corrective action was taken to uninstall and reinstall the fan coil unit in its correct position, keeping the project on track and saving a substantial amount of money.

The Knock-on Effect

This incorrect installation emphasizes the intricate interplay in construction work and the potential ripple effect of errors. Thanks to early intervention, multiple teams were able to come together and coordinate the remediation of the error swiftly and efficiently. Importantly, if engineering grade AR had been deployed when pre-surveying the positions of the fan coil unit the error would not have occurred at all.

This proves once again the need for proactive solutions that can capture errors at the earliest convenience, or before they happen, to save time and money.
