Log a delay
Record any stoppage over 15 minutes. Pick the gang, choose which precondition failed, then the specific cause. Leave the end time blank if the delay is still running.
Delays
Open delays are still running. Close one by giving its end time; hours and cost then lock in.
Dashboard
· WLC admins only. Closed delays drive the cost and hours figures; open delays are counted separately until they have an end time.
Person-hours lost per week
By precondition family
Open delays by age
Open delays have no end time yet, so they carry no hours or cost. Close them to count them.
Top causes (Pareto)
Cumulative share shows how few causes account for most of the cost.
By company
By trade
By project and section
Idle labour cost = people delayed × hours × rate per person. Shift lost = person-hours ÷ (gang size × shift length). Calculated in the database (view delay_metrics), so every screen and export uses the same figures. Plant standing time, knock-on delay to other gangs and prolongation are not included.
Gangs
Company, project and section lists on the logging screen come from these records, so a project appears as soon as it has one gang. Companies are added by WLC.
Cause list
Seven precondition families, 56 causes. Each cause names the record that should have flagged the problem before work started. Proposed list from the HAL site observation work; confirm and extend during the pilot audit.
