Elevators, Escalators & Vertical Transport Equipment calculator
Custom Option Burden Calculator
Custom options can add engineering, procurement, configuration, shop handling, field support, and inspection work that standard unit costing misses. This calculator turns option count, burden per option, capture share, and fixed engineering support into a quote-ready cost.
What this calculator does
- Estimate cost burden from custom elevator cab, fixture, controller, door, or finish options.
- an estimator needs to recover cost from non-standard elevator or escalator options
- Returns the custom option burden value for the selected vertical transport scope.
Formula used
- Variable custom option burden = custom options in scope × burden cost per custom option × custom option scope captured
- Total custom option burden = variable custom option burden + engineering and configuration cost
Inputs explained
- Custom options in scope: Use a current same-scope value for custom options in scope from the drawing, BOM, route, service record, project estimate, or field plan.
- Burden cost per custom option: Use a current same-scope value for burden cost per custom option from the drawing, BOM, route, service record, project estimate, or field plan.
- Custom option scope captured: Use a current same-scope value for custom option scope captured from the drawing, BOM, route, service record, project estimate, or field plan.
- Fixed engineering and configuration cost: Use a current same-scope value for fixed engineering and configuration cost from the drawing, BOM, route, service record, project estimate, or field plan.
How to use the result
- Use it when elevator, escalator, walkway, modernization, service, or manufacturing teams need a defensible planning number before commitment.
- It does not replace stamped engineering, code compliance review, final traffic analysis, certified test results, or project-specific installation planning.
Common questions
- What does the custom option burden calculator tell me? It gives a custom option burden result using elevator, escalator, moving walkway, or modernization assumptions from the same project, unit family, or service period.
- Which inputs should I use? Use current values from drawings, production routes, service records, supplier quotes, energy bills, inspection logs, or field plans; keep units, scope, and time period consistent.
- How should I use the result? Use the result to support quoting, production scheduling, installation planning, maintenance reserves, warranty reviews, capacity checks, or purchasing decisions.
- When is this only an estimate? Treat it as a planning estimate until final site conditions, code requirements, hoistway dimensions, duty cycle, supplier lead times, and field labor productivity are confirmed.
