EPC Services
Bid on counts, not allowances.
Operon reads the bid package — P&IDs, PFDs, line lists and the client's legacy as-builts — into a structured register your estimators verify tag by tag. Price the bid off it, carry it through detailed design as the isometrics issue, hand it to the client as-built.

The Challenge
What EPC teams face on every project
Take-offs on a bid clock
The tender window is fixed; the sheet count is not. When counting valves, in-line items and instruments off every P&ID runs past the estimate deadline, the bulks get factored off historical norms and the gap closed with an allowance — and allowances either lose the job on price or eat the margin after award.
Revision drift between issues
Between IFD, IFR, IFC and as-built the package reissues dozens of times, and the deltas are found by eye on a PDF overlay. A delta you miss is rework you absorb; a client change you catch late is a variation you argue without the revision evidence to price it.
Scope priced off the client's archive
A brownfield client hands over decades of scans, superseded revisions and no reliable tag register. Revamp scope gets priced off a walkdown sample, and on a lump-sum job everything the sample missed is growth you either qualified out of the bid or absorb in the field.
Retention behind the turnover package
Final acceptance and the back end of your retention sit behind the turnover packages — as-builts, line lists, tag registers, certification — assembled at close-out by a team already demobilizing. They ship as thousands of PDFs with no tag-to-drawing traceability, and the owner's review drags for months.
An EPC counts the same drawing set four times. Estimating counts it at bid. Procurement counts it again to raise requisitions and size the bulk buys. The change team reconciles it when the client moves a nozzle. Handover assembles it into a turnover dossier at close-out. Each pass rebuilds the structure the last one already built, then throws it away — four spreadsheets, and four versions of the truth about a single line number.
Operon reads the package once and keeps it. Every P&ID, line list and — once detailed design issues them — isometric on the job becomes a typed graph of equipment, lines, loops and instruments, connected across sheets and signed off by your engineers tag by tag. The bid take-off, the revision delta between issues, the change record and the as-built register stop being four exercises and become queries against one dataset; and when the work sits inside the client's operating plant, that same evidence is what their MOC package asks for. That is the difference between a take-off tool you shelve on the day of award and a context layer the job still runs on at close-out.
