Australia As-Built Drawings · LiDAR-Powered

For brownfield Pilbara iron ore train load-out and process plant in Australia: the LiDAR-backed reconciliation walk, the as-built drawing rebuild, and the structured handover that lets your plant team trust the documentation again.

Why as-built engineering in Australia starts with a reconciliation, not a redraft

Across the Pilbara iron-ore corridor, the North West Shelf LNG belt, and the east-coast critical-minerals build-out, a reconciled as-built drawing package is what every regulator, insurer, and digital-twin handover ultimately depends on. Australia's industrial electrical engineering market is anchored by Pilbara iron ore (Rio Tinto · BHP · FMG), the LNG west coast (Karratha · Onslow · Darwin), east coast coal-seam-gas to LNG (Gladstone), and a growing critical-minerals processing build-out. Worksafe enforcement under AS/NZS 4836 (Safe working on low-voltage installations) is the primary driver of arc flash baseline work. Australia's mining and LNG cycles built most of the existing industrial electrical asset between 2005 and 2018. The next decade is operating-cost extraction from that asset base · and the operating side is where every brownfield engineering hour matters.

The drafting standards we apply on Australia as-built engagements

P&ID and instrumentation drafting follows ISA S5.1 with PIP PIC001 as the reference for process-industry symbology. Isometric drafting follows ISO 6428. Where the operator references AS/NZS 3000 (wiring rules) · AS/NZS 3008 (cable selection) · AS/NZS 4836 (safe working LV) · AS/NZS 60079 (hazardous area) · AS/NZS 3017 (testing) · AS/NZS 3007 (mining electrical), the deliverable formatting layer aligns to it; line numbering, equipment tagging, and revision-control discipline are invariant.

What you receive · the six as-built deliverables for Australia

Asset Register + Digital Twin Hand-Off

Equipment tag list, line list, and instrument index reconciled to the point cloud. The full package hands directly to the Wistwin digital-twin platform or the operator's asset-management system with no re-registration required.

Reconciliation Walk + Discrepancy Log

LiDAR-backed reconciliation against the legacy P&ID / GA / isometric package. Every discrepancy logged with point-cloud screenshot, equipment-tag location, and recommended disposition. The log becomes the basis for the formal as-built revision.

P&ID Rebuild or Markup

P&ID drafted to ISA S5.1 in your CAD environment (AutoCAD P&ID, SmartPlant P&ID, AVEVA P&ID, Bentley OpenPlant). Where the existing P&ID is recoverable, we mark up to the as-found condition; where it is not, we rebuild from the field plus operator interviews.

Isometric Drawing Production

Isometric drafting from the LiDAR point cloud against ISO 6428 conventions. Spool list, fabrication isometric, and weld-map deliverable structure depending on the downstream workflow.

GA + Plot-Plan Reconciliation

GA drawing reconciled against the as-found equipment layout. Plot-plan updated with the new equipment positions, elevations, and access-route updates. Tie-in to civil + structural drawings where the operator package is integrated.

Process Drawing Updates

Process flow diagram (PFD), heat and material balance, and utility flow drawings updated against the as-found process configuration. Where the process has drifted from the original design (a recurring finding on plants over 20 years old in Australia), we document the drift and align the deliverable to the operating condition.

Three brownfield as-built engagements we have delivered in Australia

Three Australian engagements (Pilbara iron-ore, NWS LNG, and a critical-minerals refinery) that show the pattern:

Iron ore process plant (Pilbara)

an 80 MTPA ore-handling plant with 33 kV ring main and ball-mill drive train.

The engagement: DMIRS reportable incident on the ball-mill MCC arc flash event; full plant re-baseline against AS/NZS 4836 + Worksafe expectations + protection re-grading.

LNG (Karratha)

an LNG train with 132 kV intake and electric-drive refrigeration.

The engagement: NOPSEMA safety-case revision triggered full electrical-safety review; arc flash + insulation coordination + ground grid reconciliation across the train.

Critical minerals processing (Kalgoorlie)

a lithium hydroxide refinery with 33 kV intake and 6.6 kV distribution.

The engagement: Insurance underwriter required arc-flash baseline before policy bind on the first-of-kind plant; IEEE 1584 study + AS/NZS 4836-aligned labels.

As-Built Engineering in Australia · the questions buyers actually ask

Buyer questions we hear consistently across DMIRS Notice of Energisation, AS/NZS 4836 sign-off, and Worksafe-driven conversations:

Does the study satisfy AS/NZS 4836 sign-off expectations?

Yes. Every arc flash deliverable carries a Chartered Engineer sign-off (CEng MIE FIE) and is structured to support the AS/NZS 4836 Safe Working on LV Installations protocol your authorised person needs to operate the work permit system.

Are your hazardous-area calculations aligned to AS/NZS 60079?

Yes. The Zone classification, equipment selection, and Hazardous Area Verification Dossier (HAVD) are produced against AS/NZS 60079 series, with the dossier in the format DMIRS WA inspectors expect.

Can you support DMIRS Notice of Energisation timelines on a mining electrical project?

Yes. We structure the engagement so that the electrical-engineering documentation supports the Notice of Energisation submission to DMIRS WA without rework. The standard cycle from kickoff to Notice-ready package is 6-8 weeks.
