WHAT THE STAMP CAPTURES

8 Completion Fields — Every Job, Every Time

When the engineer finishes, The Stamp captures 8 fields that close the loop. These aren't optional — the engineer can't close the ticket without completing them. The data feeds SLA reporting, deductions defence, asset history, and the monthly performance pack.

1. Diagnosis

What did they find? Root cause, not just symptoms. Linked to asset history.

2. Work Completed

What did they do? Permanent fix, temporary repair, or escalation.

3. Parts Used

From van stock or ordered. Quantities, specs, costs tracked.

4. Time on Site

Arrival to departure. GPS-verified. Feeds labour cost analysis.

5. Status

Complete, partial fix (follow-up WO), or escalated to specialist.

6. Photos

Before/after minimum. Timestamped, geotagged, against the ticket.

7. Signature

Customer sign-off on tablet. Name, role, timestamp. Stored immutably.

8. Follow-Up?

If partial fix: follow-up WO auto-raised with scope from diagnosis.

TKT-2026-03847 — COMPLETION RECORD

Library Roof Leak — Engineer's Full Report

TKT-2026-03847 Completion Record

DIAGNOSIS

Failed lead flashing at northeast valley gutter. The existing silicone sealant repair (from Jan 2026, TKT-02891) has cracked and separated from the lead at the lap joint. The underlying lead flashing is corroded — approximately 600mm of degraded flashing allowing water ingress during heavy or sustained rainfall. This is the root cause of the recurrent leak (3rd call in 7 months). Temporary repairs are no longer effective. The flashing needs full replacement.

WORK COMPLETED

Temporary weatherproofing applied internally and externally.
External: Flashing tape (self-adhesive bitumen) applied over the failed lap joint as an interim measure. This will hold for 4–6 weeks in normal weather conditions. Not a permanent solution.
Internal: 2 saturated ceiling tiles removed and replaced. Water mopped from carpet. Extraction fan positioned to dry remaining damp patch on wall. Wall socket inspected — no water ingress into the back box. Confirmed safe. Reading lamp reconnected.

PARTS USED

Flashing tape (self-adhesive bitumen, 150mm wide) — 1.2m used from van stock, £12.40.
Ceiling tiles (600×600 mineral fibre, Armstrong Cortega) — 2 used from van stock, £8.60 each = £17.20.
Total materials: £29.60. No parts ordered.

TIME ON SITE

Arrived: 10:38. Departed: 13:15. Time on site: 2hr 37mins. Labour cost (at contract rate): £131.50.

STATUS

PARTIAL FIX — Follow-up required. Temporary repair only. Permanent repair requires full lead flashing replacement at the valley gutter (estimated 2.4m run). This is a Grade II listed building — lead replacement requires listed building consent from Aldgate BC planning department. Follow-up WO-2026-00847 auto-raised.

SIGNATURES CAPTURED

First-visit fix improvement: 12 months ago, first-visit fix rate was 64%. The combination of better briefs (The Brief, Stage 03) and van stock forecasting has improved this to 78%. Each percentage point saved is approximately 1.8 return visits per month — at £95 per visit, that's a £171/month saving per point.

Evidence gaps (remaining 4% photos, 9% signatures): The 4% photo gap is almost entirely P4 planned works where engineers judge photos unnecessary (cosmetic repairs, signage). The 9% signature gap is split between unattended sites (keyholder left before completion) and after-hours emergency calls where no site representative was present. Both are tracked and reported.

STAGE 05 GATE — THE STAMP

Stamped Complete. Evidence Chain Intact.

✓Diagnosis / root cause documented (linked to asset history)

✓Work completed described with method and extent

✓Parts used recorded with quantities and costs

✓Time on site captured (GPS-verified arrival/departure)

✓Before/after photos uploaded and geotagged

✓Customer signature captured on tablet

✓Completion status set (complete / partial / escalated)

✓Follow-up WO auto-raised if partial fix

Handover to Stage 06 — The Score™: TKT-03847 closed as partial fix. SLA response and fix both met. Follow-up WO-2026-00847 raised for permanent flashing replacement (subject to listed building consent). The Score will record this as SLA-compliant and flag the follow-up for tracking.
