Trigger, activity, conclusion
MEP systems approaching practical installation completion and the T&C programme is due to commence — requiring a pre-commissioning walkdown.
Using 360° capture walkthroughs and camera footage to document and verify the condition of MEP installations.
MEP commissioning record includes timestamped 360° and camera documentation of installed systems at point of sign-off.
Workflow steps
- Step 01
MEP subcontractor notifies main contractor that systems are ready for pre-commissioning inspection; walkdown date agreed.
Inferred - 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 - Step 03
Camera footage from fixed cameras covering plant rooms or major equipment reviewed to confirm when installations were completed.
Inferred - 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 - Step 05
Outstanding items identified during the virtual walkdown logged as a pre-commissioning punch list and issued to the MEP subcontractor.
Inferred - Step 06
Punch list items resolved and follow-up 360° walkdown conducted to verify close-out.
Inferred - Step 07
Formal T&C commences. 360° model used as reference for locating equipment and tracing pipework/cable runs.
Evidenced - Step 08
Where a commissioning failure is identified, 360° and camera footage reviewed to determine whether defect was present at pre-commissioning walkdown.
Inferred - Step 09
Commissioning sign-off documentation includes reference to 360° capture record as visual baseline of installed condition at handover.

Evidence records
360° footage used during MEP commissioning walkdowns to verify that installations are complete and correctly configured before formal commissioning sign-off commences.
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.
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.
ROI model
rework prevention
Evercam enables early detection of deviations from design, reducing rework costs. Saving is a fraction of the rework that would otherwise occur.
saving = project_value × rework_rate_pct × early_detection_pct × evercam_contribution_pct
