Estimating
A screening range in minutes, a budget estimate built from the equipment list the rules sized, readiness checks on the class you claim, and the basis of estimate an operator's auditor asks for. Priced from a cost library your firm owns and your closed projects calibrate.
Class references follow AACE 18R-97. A new firm prices from the core seed library, which the product labels seed-only on every line until the firm's own rates, curves, and reconciled projects replace it. No accuracy is claimed beyond the class band the estimate prints.

Seeded demo estimate, core seed library only; 31% of direct cost on placeholder prices, as the estimate reports.
Two classes, one method
Before any line is priced: a capacity reference for the facility type scaled in three buckets (fixed pad scope on well count, process trains on throughput, per-well items one for one), beside your firm's nearest closed projects scaled and escalated. A range, not a point, and the report prints screening estimate on every page.
Each sized equipment tag maps to a cost module and a size band; the band's curve gives the equipment price at its index month, escalated to the estimate date. Bulks by discipline as factors of equipment, labor as crew hours times the regional rate times productivity, subcontracts as allowances, facility-level modules derived from the equipment list.
Major equipment, bulk materials, construction labor, subcontracts, indirects, taxes by jurisdiction with direct pay handled as a shift to the operator, engineering and PM fee, owner's costs, escalation to the construction midpoint, contingency by facility type and class, total. Every estimate carries every layer, so two estimates always compare.
Defensible
An operator's auditor reads the exclusions first, then the basis, then the sources. The estimate carries all three, generated from the run rather than assembled afterward.
Class is a claim the estimate makes. Readiness rules test it against what the engine observed: unmapped tags, prices past a curve's range, error-severity spec warnings, assumed inputs, the share of the total on uncalibrated or placeholder prices, exclusions stated. Issuing above what readiness supports needs a written justification.
Scope, design maturity, method by layer, pricing sources with index months, assumptions from the spec, exclusions, allowances, escalation and contingency basis, the exact library snapshots: generated from the run. Purpose, scope notes, and risks: written by the estimator. Both freeze with each issued version.
Clone the draft to defer the LACT or price a later spec version, compare side by side, promote the one that wins. Every issued version is frozen with its lines, stack, settings, readiness, and overrides; any two diff line by line by stable equipment identity.
Price, quantity, factor, rate, or exclude, on any line, always with a written reason. Overrides carry forward when the spec changes and are listed as orphaned, never applied silently, when their line is gone.
The learning loop
Modules, curves, rate tables, factors, tax rules, escalation indices, readiness rules. Every entry carries its sources, a verified or practice tag, and a confidence: seed only, thin, or calibrated by three or more of your reconciled projects.
Import rate sheets, curves, factors, and closed projects from spreadsheets in the template layouts, or shadow a core entry by code or a single size band. Drafts preview against your open estimates before they go live.
Import invoices against an issued version, map lines to modules with the mapping remembered per client, assign variance causes, close. Closed reconciliations write signals; enough projects moving a factor or a curve band the same way produce a calibration proposal with its evidence, for the library owner to accept.
The portfolio shows the firm its active and stale estimates, the share of its library still on seed prices, open calibration proposals, and, once reconciliations close, mean absolute variance by class, facility type, region, and module. How the libraries work
