Specify the exact engineering units, select deliverables and apply verified hours-per-unit from measured work. Four specialist models are available. No productivity rates are invented or preloaded. Until evidence is available, you can still export a complete scope and request a custom quotation.
Each line has an explicit quantity and its own low/high hours per unit. Dense drawings, variants, wiring channels and field loops are distinct engineering units. A task with zero quantity is excluded.
Engineering work-rate assumptions are configured from measured demonstration time logs, not requested from the customer.
Record actual task hours on self-produced demonstration projects, excluding setup, QA and customer revisions. Group time logs by task, quantity and source condition. Import rates only after independent trials; otherwise use manually entered, explicitly unverified allowances. A calibration kit is provided separately for this prototype.
The original eight-package model remains available below with its earlier editable provisional assumptions. These are not validated measured productivity norms. The new four specialist models above never reuse those rates without evidence.
Archived engineering assumptions are retained only for internal comparison. They are not time-calibrated and should not be used to quote commercial work.
Planning assumptions were moderated in October 2026 against published freelance/contractor rates. Per-item engineering hours remain provisional until validated against completed work. This is not an offer.
Load example: 5 work packages (100 I/O, 45 loops, 80 cables, 2 panels, 30 FAT tests) ↗
Add individual deliverables and quantities. Each package has its own setup hours; shared engineering work and overlaps are not deducted automatically.Engineering effort is calculated for each selected work package, taking into account document quantities, technical complexity, available input data and the expected number of review cycles.
Combine individual packages to explore an indicative project-level effort and budget before preparing an RFQ.
The estimate supports initial planning. Final pricing is confirmed after reviewing the project scope and available information.
Discuss the estimated scopeUnit allowances below are internal planning hypotheses for defined deliverables with reusable templates, accessible references and consistent input data. They are not measured industry averages, contract prices or guaranteed production rates. A separate vendor review and technical qualification is required before any binding RFQ.
| Package | Setup | Per unit | Scope boundary |
|---|---|---|---|
| I/O List + Instrument Index | 6 h | 0.32 h / I/O point | Known tag/loop basis; excludes field survey and signal discovery |
| Instrument Loop Diagrams | 8 h | 1.90 h / loop | Reuse of approved typicals; excludes new instrument design |
| Cable + Terminal Schedules | 7 h | 0.38 h / cable | Cable and terminal source data available |
| Control Cabinet Documentation | 14 h | 40 h / panel | Standard/reusable panel topology; no panel fabrication, UL/CE certification |
| FAT/SAT Test Documentation | 8 h | 0.90 h / test case | Test scripts and checklists; not FAT attendance or test execution |
| Electrical CAD Sheet Conversion | 6 h | 1.50 h / sheet | Source drawings available; excludes redesign |
| Document Review | 5 h | 1.20 h / document | Defined review checklist and document maturity |
| EPC / FEED RFQ Support | 12 h | 10 h / vendor package | Documentation/tender support, not engineering sign-off |
All planning budgets exclude taxes, CAD licences, legal certification, site attendance, travel, insurance, field work, statutory approvals and third-party testing. For scopes involving regulated engineering sign-off, use locally qualified professionals. Calibration will be updated using anonymised time logs from completed work.
