Catch the problem
in the drawing,
not on the job site.

EPC contractors review thousands of datasheets, P&IDs, BODs, and SPPs against owner standards on tight schedules. The Platform compresses review cycle time, frees senior engineers from lookup, and produces audit-ready citations PMC teams accept on first pass. Same engine across capital projects, brownfield expansions, and turnarounds.

The Challenge

Drawing review is on the critical path. Always. Everywhere.

Rework from issues that were present in drawings but never caught accounts for 3โ€“7% of total project value across large EPC projects. The problems don't appear on site โ€” they were already there. They just weren't found in time.

01

Drawing reviews are on the critical path

P&IDs, isometric drawings, and weld maps are reviewed by hand against ASME, API, and NACE requirements. On a large project there are thousands of them. Review becomes the bottleneck everything else waits on.

02

Issues found late cost a fortune

A non-conformance caught in a drawing review costs almost nothing to fix. The same issue found during a turnaround or on a live site triggers rework, schedule overruns, and contractor disputes that run into the millions.

03

No project runs on one standard

A single pipeline scope might require simultaneous compliance with ASME B31.3, API 570, NACE SP0169, and a client-specific specification. Cross-referencing them manually takes hours โ€” and gaps still slip through.

04

Turnarounds have no room for slow checks

Plant turnarounds are scheduled to the day. Every compliance check that takes two days instead of two hours extends downtime directly. In refining, each additional day offline costs more than most people want to calculate.

05

Standards knowledge walks out the door

The engineers who know ASME B31.3 inside out are retiring. What they know lives in their heads, not in a system. When they leave, every junior engineer starts from scratch on questions that should already be answered.

06

Proving compliance during inspections is painful

When a regulator, client, or certifying authority asks for evidence โ€” pulling together a traceable record from drawing to sign-off to standard is a manual exercise that takes weeks.

How It Works

Connected to your tools in weeks. Not months.

The Platform connects to your existing engineering document management systems โ€” AVEVA, Aconex, SmartPlant, SAP PM โ€” via Model Context Protocol and REST APIs. Your standards library is ingested and kept current. Your existing workflows stay intact, they just get a lot faster.

  1. 1

    Ingest your standards stack

    Owner codes, ASME, API, NACE, ISO, project specs, addenda. The Platform reads every clause, table, and applicability condition. When an edition or addendum changes, it updates automatically.

  2. 2

    Scope it to your project

    Tell The Platform which standards apply to which equipment types, process conditions, and geographies. Addendum-override hierarchy is enforced automatically from there.

  3. 3

    Reason clause-by-clause

    Datasheets, P&IDs, BODs, drawings, and specs are reasoned against every applicable clause. Findings are severity-classified โ€” Critical, Major, Minor, Observation โ€” with the supporting clause and engineering rationale.

  4. 4

    Reviewer approves, overrides, or escalates

    Human-in-the-loop at every step. Every decision is logged. Every override teaches the system. Cited Excel and PDF reports are generated for PMC review.
