30 / 60 / 90% Model Review Checklists
Indicative 30%, 60% and 90% piping model review checklists. Pick a stage, mark each row OK, ACTION, N/A or HOLD, add comments and initials, and download a PDF for the review record.
Each stage is tied to an indicative Level of Development: about LOD 200 at 30%, LOD 300 at 60% and LOD 350 at 90%. These are a starting point, not a standard. Your project’s BIM execution plan, model progression specification or contract governs what each review must cover.
The 90% review feeds straight into the Isometric Release Gate Checklist. For background, see Project stages, LOD and process piping and Lesson 1: What a Piping Designer Does.
