One morning's tickets, from the one-call feed to a standby on site
Lumina Utilities' Westmere depot, Tuesday 13 October 2026. At 16:18 yesterday, Halvorsen Civils filed ticket 2610-18342 to renew the storm drain along Corran Road with a tracked 21 t excavator. Here is what happens next, screen by screen, in the working solution.
- 01Morning
704 tickets on the board, 38 new since yesterday
Nadia Farouk · Damage prevention coordinatorNadia owns the response to every ticket in Lumina's area. The dig map opens on the Westmere depot: 704 tickets on the board, 89 replies due today, none late — 7 standby, 36 elevated, 161 locate and 500 clear. Thirty-eight new tickets have come in from the one-call centre since 16:05 yesterday, waiting to be screened over the buried cables and mains, drawn in the colours field crews know.

Five agents screen the 38, in order
Ticket reader, Asset overlay and Risk scorerNadia presses Screen 38 new tickets. The ticket reader reads work, method, depth and extent from each description; four gave no depth, so the method's worst case is used. The asset overlay draws 38 dig areas with a 3 m buffer and finds 61 Lumina assets inside, and holds one area where as-builts are not yet posted. The risk scorer scores 37: 27 clear, 7 locate, 2 elevated, 1 standby on Mill Lane over a 600 mm trunk main.
Clear responder: “sent 27 no-conflict replies · code 10 to the one-call centre and an email to each excavator · 07:43”

Corran Road turns red: standby required
Risk scorerThe last dig area draws along Corran Road and crosses the 132 kV cable route. Halvorsen Civils plan a tracked 21 t excavator to 1.8 m; the Westmere–Ashby 132 kV circuit 2 was laid at 1.1 m in the 2009 as-laid survey, so the bucket would go 0.7 m below it. Score 94 of 100. The depth section on the right draws the trench to its depth, each asset at its recorded depth with its 0.5 m safe margin.
“Rule: a mechanical excavator within 3 m of a cable of 33 kV or more always gets a standby.”
- 04What if
Switch to vacuum excavation, and the score falls to 69
Nadia Farouk · Damage prevention coordinatorNadia tries the other methods on the depth section. With vacuum excavation to the same 1.8 m, the method adds 6 points instead of 22 and the safe-margin points fall from 18 to 9, so the score falls to 69 and the outcome becomes elevated: the locator marks out, then meets the excavator on site before work starts. The rule floor no longer applies. The change is a what-if only — the ticket still says mechanical excavator.
“What-if: the ticket says mechanical excavator to 1.8 m (score 94). Not saved.”
- 05The ticket
Every value read from the ticket, every asset inside the dig
Ticket reader and Asset overlayThe ticket as received is shown with the start, location, depth and method highlighted where the ticket reader found them. Six assets lie inside the dig area and its 3 m buffer: the 132 kV circuit crossing at chainage 76 m, its protection signalling fibre at 78 m, the Tanner's Row 150 mm main at 104 m and 11 kV feeder at 120 m, six 25 mm service pipes, and a 450 mm ductile iron trunk main 2.1 m beside the trench — 1.4 m ±0.4 from a 1978 drawing, estimated.
Why 94: 132 kV cable +35 · mechanical excavator +22 · dig reaches the 0.5 m safe margin +18 · 2 crossings +8 · excavator history +7 · depth uncertain +4
- 06Who is digging
Halvorsen Civils carries +7 for its strike history
Risk scorerThe excavator history adds points for strikes in the last 24 months: one strike +4, two +7, three or more +10. Halvorsen Civils has 412 tickets in 12 months and 2 strikes — an 11 kV cable at Linden Close in February 2026, mini excavator, clearance not kept, and a 100 mm main on Ashby Road in July 2025. Nadia can send a safe-dig briefing before Thursday's job.
“Strikes in the last 24 months add to each new ticket's risk score.”
- 07Decide
The precautions, drafted and confirmed
Nadia Farouk · Damage prevention coordinatorThe locator dispatcher has drafted everything the dig needs: Tomás Ruiz, HV-qualified, marks out Wed 14 Oct 09:30, before the reply is due; a pre-dig meeting on site Thu 15 Oct 07:00 with Callum Pryce, Halvorsen's site foreman; Ashby crew 2 on standby 07:00–15:30; trial holes by hand at chainage 76 m and 120 m; and safe-dig instructions to Halvorsen Civils. Nadia signs, and it goes to the cable engineer.
“No machine within 0.5 m of the indicated line until the asset is exposed.”
- 08Approved
The cable engineer approves, and the reply goes back
Dev Mistry · Third-party works engineer, transmission cablesAny work within 3 m of a 33 kV or 132 kV cable needs Dev's approval. Once he approves, code 30 — marked, site meeting and standby — goes to the one-call centre, and the safe-dig instructions, with asset plans, depths, the 0.5 m margin and the standby contact, go to Halvorsen Civils.
“Dev Mistry approved · code 30 sent to the one-call centre”
- 09The field day
Locators by qualification, standbys against the dig start
Locator dispatcherThe locator board shows 8 locators and 113 mark-outs in route order, with travel time from each depot. HV work goes only to HV-qualified locators: Tomás Ruiz in Westmere carries 16 jobs, 79% booked. Standby crews are booked against each dig start — Ashby crew 2 (Owen Hart, Sina Taufa) for Corran Road on Thursday, and the trunk mains crews for the big water mains.
“HV work goes only to HV-qualified locators; standbys are booked against the dig start.”
- 10Later
A person checks 5% of the clears
Nadia Farouk · Damage prevention coordinatorEvery clear says why it was clear — the nearest asset and its distance against the 15 m clear distance — with the reply time and code 10. Today's sample is 26 of 527 clears, and Nadia marks each Agree or Should have been located. Three tickets on the new Kestrel Fields estate were held, not cleared: the phase 2 as-built drawings for LV and water are not posted yet, so they went to a locator.
“Any area with as-builts still to post is held, not cleared.”
