Risk Radar preview

AI-Powered Risk Analysis — Available on Professional Plan
Low risk

Duct fabrication ahead of erection

The shop is holding a 4-week buffer over site erection, so no crew has waited on fabrication this month.

Recommended mitigation: Keep the fabrication shop on the current shift pattern.
Forecast impact: No impact; buffer protects the erection sequence.
Medium risk

Two chillers pending delivery

4 of 6 chillers are installed; the remaining two are due in 5 weeks, which compresses plant-room commissioning.

Recommended mitigation: Confirm the despatch date in writing and pre-complete all piping and electrical interfaces at the two vacant bases.
Forecast impact: 10–14 days on plant-room commissioning.
Critical

BMS integration behind, blocks TAB

BMS field device installation is at 65% with integration testing not started; TAB cannot begin without it and the client handover date is fixed.

Recommended mitigation: Add a dedicated controls team and start zone-wise TAB on completed halls rather than waiting for full BMS closure.
Forecast impact: 21 days on handover if integration is not accelerated now.

Hall 3 ducting reached 88% erected and pressure testing cleared on two branches. Chilled water piping welding continued in the plant room. BMS cabling in Hall 2 was held for six hours pending cable tray handover from the electrical contractor — logged as a hindrance.
