DEDUCTIONS DEFENCE — TKT-03829

Keyholder Delay — Defence in Progress

TKT-2026-03829 Deduction Defence

DEDUCTION
£250 — P2 response breach (4h45m vs 4h target)
DEFENCE
Keyholder delay. Engineer D. Okonkwo arrived at Parkside Library at 3h10m after call receipt — within the 4hr response target. However, the caretaker (keyholder) did not arrive until 45 minutes later. The SLA response clock should start from the point access was available, not from call receipt, per Contract Schedule 4, clause 8.3(b): "where access is dependent on a third party, the SLA clock pauses until access is provided."
EVIDENCE
Engineer GPS arrival timestamp (3h10m) · Engineer app log showing "waiting for keyholder" status at 3h10m · Caretaker arrival logged at 3h55m (45-min wait) · Call log to caretaker at 3h15m (no answer) · Second call at 3h30m (answered, confirmed en route) · Photo of locked building entrance at 3h12m
STATUS
Submitted to H. Marsden (Aldgate BC contract manager) 16 May. Response pending. If accepted: £250 deduction reversed. If rejected: escalation to NEC4 TSC dispute resolution procedure.
