JOB REFERENCE: JB004-26-00938

Leakage has been identified at drainage pipe T-fittings within twenty‑four (24) shafts of the Jewellery & Gemplex Buildings. The drainage pipelines, originally installed in 2004, have deteriorated due to prolonged and unrectified leakage from chilled water pipe insulation. Continuous water exposure has caused failure of pipe clamps, weakening and collapse of supports, sagging of pipelines, and cracking of multiple T‑connections. Offices located below the affected risers are experiencing water ingress and operational disruption.

Immediate remedial action is required to prevent further structural damage and system failure.

• Inspect twenty‑four (24) shafts to identify all damaged drainage pipe T‑fittings, supports, and clamps.
• Dismantle and replace damaged T‑joints in the affected drainage pipelines across twenty‑four (24) shafts.
• Replace all failed pipe clamps within twenty‑four (24) shafts.
• Restore, reinforce, and realign weakened or collapsed pipe supports in twenty‑four (24) shafts.
• Rectify leakage points in chilled water pipelines serving twenty‑four (24) shafts.
• Remove and replace damaged chilled water pipe insulation in affected areas of twenty‑four (24) shafts.
• Test and verify drainage and chilled water systems to ensure proper alignment, support integrity, and leak‑free operation.
