Following the outcomes of this inspection: 

the Main Contractor requested that all underfloor services in this area of the building were to be set out using XYZ.

Problem

As part of a shift towards more modern construction methods, prefabricated elements and the associated factory witness testing became a critical hold-point and interface in the construction process. The witness testing component became even more important as travel restrictions during the COVID-19 pandemic created a Health & Safety risk and made regular factory visits infeasible.

Scope

To overcome the many restrictions and constraints created by the COVID-19 pandemic, the Main Contractor and XYZ Reality collaborated to redefine Factory Witness Testing procedures. This included:

  • Bringing the Factory Witness Testing to site by creating a designated inspection zone
  • Remote streaming the inspection captured by The Atom AR headset and viewed through HoloSite to maximise visibility for relevant parties
  • Incorporating interfacing elements into the inspection

Results

During one of the first deliveries of a prefabricated fibre cable chamber, site teams immediately identified two errors by viewing models of the chamber on its own and models of the interfacing ductwork:

  • Base of concrete 200mm too wide
  • Ductwork openings misaligned by 75mm

By catching this error quickly, the chamber prefabrication could be reconfigured to the correct dimensions avoiding future installation errors and rework. In addition, all relevant package managers and trade contractors could validate or reject the inspection through the live streaming capabilities of The Atom
