120-Sheet P&ID Take-Off Automation for EPC Contractor

120-Sheet P&ID Take-Off Automation for EPC Contractor

An international EPC contractor sought to accelerate material take-off (MTO) generation for a large-scale hydrocarbon processing facility. iCaptur deployed its P&ID Intelligence Platform to extract, resolve, and derive a complete, spec-driven MTO directly from the engineering package. 

The Challenge

The client’s project package comprised 120 complex P&ID sheets for a multi-train hydrocarbon processing facility. The sheets featured fragmented CAD vector exports, intersecting utility headers, and dense instrumentation clusters, conditions that consistently broke manual take-off workflows.  

Previous manual attempts had produced inconsistent line-tag assignments at header crossings, missed inline reducers on fragmented vector paths, and outright omission of bulk joint components such as flanges, gaskets, and bolt sets. Each of these gaps typically surfaced late in the project cycle as a procurement shortfall or field correction, creating recurring bottlenecks across engineering, procurement, and quality review. 

Solution

iCaptur deployed its P&ID Intelligence Platform, built on a deterministic-hybrid extraction pipeline.  

  • All 120 drawing sheets were ingested concurrently, with vector primitives parsed and title-block exclusion zones filtered in under 4 minutes.  
  • An axis-locked topological ray-marching engine mapped 4,500+ inline components, including valves, reducers, and blinds, directly to their parent pipeline line numbers. 
  • Symbol classification against ISA-5.1 descriptors identified and categorized in-line components across the full package.  
  • Spec-driven rule application cross-referenced ASME B16.5 thickness tables to automatically generate 18,000+ derived mechanical joints, including mating flanges, gaskets, and stud-bolt sets.  
  • Standardized outputs were exported directly into SAP-compatible MTO workbooks, structured for immediate use by procurement and engineering teams.  

The system resolved pipeline topology deterministically, eliminated cross-header component misattribution, and delivered an audit-traceable take-off that engineers could review by exception rather than rebuild from scratch. 

Outcome

The automation system delivered significant improvements across the take-off and procurement workflow. It compressed total MTO generation time from 3 weeks of manual engineering labor to 8 minutes of automated execution, achieved a 99.4% automated line-assignment success rate across 4,500+ inline components, and eliminated cross-header leakage entirely. Overall, the solution reduced downstream procurement reconciliation effort by 85%, while unassigned component exceptions fell to near-zero, helping the organization achieve faster take-off cycles, standardized MTO documentation, and stronger procurement readiness.
