Digitise as-built documents and reconcile against issued-for-construction (IFC) drawings. Capture field red-line markups, handwritten annotations, and deviation records into a structured change register. Turn decades of paper redlines at brownfield plants into a current-state digital twin data layer. Blue-ocean workflow; no software competitor anywhere fully automates field-redline-to-structured-register conversion for process plants.
Field red-line markups captured and structured (handwritten annotations, highlight colours, cross-outs, inserted text, added tags, modified line numbers, deleted equipment), all classified by change type and location on the source drawing.
Systematic comparison of issued-for-construction (IFC) documents against as-built redlines. Every deviation identified, classified (tag-added / tag-deleted / tag-modified / attribute-changed / routing-changed), and quantified for MoC impact analysis.
Legacy plant drawings digitised into structured data for asset management modernisation. Typical Indian PSU refinery engagement: 30-50 years of accumulated paper redlines (commissioning redlines, turnaround redlines, MoC redlines) converted into current-state plant register. Scales to 10,000+ drawings per facility.
All field changes tracked in a structured register with P&ID reference, change type, date of change, source redline reference, responsible engineer, MoC ID linkage (if available), and verification status. Feeds directly into SAP PM change management or IBM Maximo work management.
Redlines carrying MoC references linked to the originating MoC record. MoC-to-as-built completeness scoring surfaces gaps (MoCs approved but not reflected in as-built; as-built changes without MoC traceability). Audit-critical for safety-regulated operations (OISD 118, PESO, CCOE).
Reconciled as-built changes auto-populated into SAP PM functional location / equipment master or IBM Maximo asset / location updates. Brownfield digitisation becomes a live asset-master refresh rather than a one-time migration project.
As-built P&ID changes cascade to datasheets, line lists, valve lists, equipment lists, and C&E matrix. Integrated with /reconciliation for cross-document consistency validation after as-built capture.
Redline batches uploaded by 9am are returned as structured change register within 48 hours. Contractual SLA applies. Volume pricing for brownfield digitisation campaigns scales to 5,000+ drawings per quarter.
Post-commissioning as-built capture: IFC drawings plus field redlines consolidated into Day-1 operational asset register
Brownfield plant digitisation at Indian PSU refinery (IOCL / BPCL / HPCL / ONGC): 30+ years of accumulated redlines converted to current-state digital register
Turnaround as-built refresh: post-outage redlines capturing replaced equipment, modified piping, new instrumentation fed into SAP PM
MoC-to-as-built completeness audit: every approved MoC validated for as-built reflection; gaps surface for OISD / PESO audit
Revamp project baseline: pre-revamp as-built capture establishes accurate starting point for revamp P&ID design
Insurance / asset valuation audits: current-state plant documentation for accurate asset valuation and insurance coverage
Acquisition due diligence: as-built documentation assessment for plant acquisition (pharma, chemicals, refining sectors frequently M&A-active)
Digital twin initialisation: as-built data layer for AVEVA AIM / Cognite Data Fusion / Bentley iTwin twin population (see /solutions/digital-twin-data-integration)
Yes. Pathnovo processes scanned paper P&IDs, faded drawings, hand-marked as-built annotations from any era, and photographed drawings from mobile cameras. Handwritten revision markups from multiple engineers over decades are interpreted correctly. 99.5% contractual accuracy on text and tag extraction; 97-98% on heavily annotated legacy drawings with accuracy estimates provided per batch before full processing. Reference benchmark: McDermott engagement processed 600 P&IDs with 10,247 tags at zero QA rejections; similar scale deployable for brownfield operators.
IFC-vs-current-P&ID comparison (/solutions/procurement-intelligence/pid-revision-po-impact) compares two revision states of the same engineering document, Rev A vs Rev B during design / construction. As-built reconciliation compares the engineering document (IFC) against the field-installed plant state captured in handwritten redlines: the delta between what was designed and what was actually built or modified in service. These are different workflows with different inputs, both supported by Pathnovo.
Any format: scanned paper redlines (PDF, TIFF, JPEG), photographed redlines from mobile cameras, digital annotations on PDF (Adobe / Bluebeam markups), electronic redlines on CAD-based tools (SmartPlant P&ID, AVEVA P&ID markup), Excel-based change logs. Handwritten annotations in English, Hindi (Devanagari), and regional scripts supported. No pre-processing required.
Yes. Every redline is tagged to its originating MoC record (where available in the source document). MoC-to-as-built completeness scoring identifies approved MoCs not yet reflected in as-built and as-built changes that lack MoC traceability, both of which are audit findings for OISD 118 / PESO / Chief Inspector reviews. For safety-critical plants, this is non-negotiable regulatory automation. See /compliance/indian-epc-compliance-bundle.
Brownfield digitisation runs on the credit-based tier model. Smaller facility engagements (500-2,000 drawings) fit comfortably inside Professional (5,000 credits/month) or a few months on Starter for staged rollout. Indian PSU refinery digitisation across 5,000-15,000 drawings with 30+ years of accumulated redlines and MoC linkage typically sits on Scale (25,000+ credits) or Enterprise on 3-year contracts with one-time data-room ingestion priced per page for the historical archive. Indian PSU rate-card compatibility available. See our pricing page for full plan details.
Reconciled as-built changes feed directly into SAP PM functional location / equipment master updates via IDOC / BAPI / OData, or IBM Maximo asset / location updates via MIF / MEA. For operators running dual ERP environments, both feeds run concurrently. See /solutions/engineering-handover/sap-pm-integration and /solutions/engineering-handover/maximo-integration for integration detail.
