Trigger, activity, conclusion

01 · Trigger

MEP systems approaching practical installation completion and the T&C programme is due to commence — requiring a pre-commissioning walkdown.

02 · Activity

Using 360° capture walkthroughs and camera footage to document and verify the condition of MEP installations.

03 · Conclusion

MEP commissioning record includes timestamped 360° and camera documentation of installed systems at point of sign-off.

Workflow steps

  1. Step 01

    MEP subcontractor notifies main contractor that systems are ready for pre-commissioning inspection; walkdown date agreed.

    Inferred
  2. Step 02

    360° capture walkdown of MEP plant rooms, service corridors, riser shafts, and distribution areas conducted — timed to coincide with or immediately precede the formal pre-commissioning inspection.

    Evidenced
  3. Step 03

    Camera footage from fixed cameras covering plant rooms or major equipment reviewed to confirm when installations were completed.

    Inferred
  4. Step 04

    360° model reviewed by M&E engineer and commissioning manager — either on-site via tablet or remotely — to identify outstanding installation items before testing commences.

    Evidenced
  5. Step 05

    Outstanding items identified during the virtual walkdown logged as a pre-commissioning punch list and issued to the MEP subcontractor.

    Inferred
  6. Step 06

    Punch list items resolved and follow-up 360° walkdown conducted to verify close-out.

    Inferred
  7. Step 07

    Formal T&C commences. 360° model used as reference for locating equipment and tracing pipework/cable runs.

    Evidenced
  8. Step 08

    Where a commissioning failure is identified, 360° and camera footage reviewed to determine whether defect was present at pre-commissioning walkdown.

    Inferred
  9. Step 09

    Commissioning sign-off documentation includes reference to 360° capture record as visual baseline of installed condition at handover.

    Inferred

Camera footage used specifically during mechanical, electrical, and plumbing testing and commissioning phases — confirming the workflow's distinct identity within the broader progress documentation landscape.
Anonymized evidence record 48.2
Aidan was able to pull out his phone, open 360 view on the mobile app and show that the works had already been done. This saved time and reduced the need for written documentation.

rework prevention

Evercam enables early detection of deviations from design, reducing rework costs. Saving is a fraction of the rework that would otherwise occur.

Formula

saving = project_value × rework_rate_pct × early_detection_pct × evercam_contribution_pct
