COBie.Component.WarrantyStartDate -- Expected Values

The COBie.Component.WarrantyStartDate parameter records the official start date of the warranty period for a component.\ This value is essential for facility operations, maintenance planning, and lifecycle management.\ It must follow a consistent, machine-readable format aligned with COBie and ISO standards.

Validation Rules (DAQS)

  1. Mandatory where warranties apply\ Components covered by manufacturer or contractor warranties shall include a valid warranty start date.

  2. Format requirement\ All dates shall follow ISO 8601:\ YYYY-MM-DD

    Examples: 2025-05-12, 2024-09-01

  3. No placeholders or ambiguous formats\ The following are not permitted:

    • TBD, N/A, Unknown
    • 12/05/2025
    • May 12, 2025
    • 12-5-25
    • --

  4. Logical consistency

    • WarrantyStartDate shall not precede the InstallationDate (if provided).\
    • It shall not be set in the future at the moment of COBie handover.\
    • If the warranty begins on commissioning acceptance rather than installation, the correct contractual date must be used.

  5. Responsibility\ The warranty start date is provided by the contractor, commissioning team, or manufacturer depending on contractual agreements.

  6. One start date per component\ Multi-phase or conditional warranty dates are not permitted.

Good Examples

Component Type Valid COBie.Component.WarrantyStartDate

Pump 2025-06-01 Air Handling Unit 2024-11-15 Fire Alarm Panel 2025-02-10 VRF Outdoor Unit 2024-12-01

Common Mistakes

Incorrect Value Issue

TBD Not permitted---missing required information

11/05/2024 Wrong date format

2026-03-01 Future date relative to COBie delivery

Installation Not a date

Empty Missing required warranty information

Relationship to Revit

Autodesk's COBie Extension typically maps this value from:\ Revit → Instance Parameter "Warranty Start Date"\ (or an equivalent shared parameter defined in the COBie template).

Notes: - This must be an instance parameter.\ - Design authors do not populate this value; it is provided during construction or commissioning.\ - Values shall match commissioning sheets, warranties, or O&M documentation.

Best Practices

  • Enter warranty dates directly from manufacturer or contractor documentation.\
  • Ensure alignment between installation, commissioning, and warranty activation procedures.\
  • Validate all warranty dates before COBie export to ensure compliance with ISO and client requirements.\
  • Keep warranty values consistent across Revit, COBie, and O&M systems.\
  • Avoid assumptions---use only confirmed contractual dates.
