Trace each partition type from the plan into its wall-type schedule, board and framing requirements, and rating basis, then compare layer count, joint treatment, and fire and sound performance for the same assembly before treating two similar-looking walls as equivalent.
Assemble the review package
Gather the partition-type schedule or legend, floor plans, the reflected ceiling plan for head-of-wall conditions, the life-safety or rating plan, and the issued gypsum board specification. Include acoustic and moisture-resistant product data where relevant. Review one partition type completely before assuming a similar tag elsewhere carries the same requirements.
WBDG publishes UFGS 09 29 00: Gypsum Board as a public guide-specification reference (accessed September 16, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| Type assignment | Plan partition tag + partition-type schedule | Does every reviewed wall resolve to a defined assembly? Record generic or unlabeled partitions. |
| Board type and layers | Assembly description + board product clauses | Do layer count, board type (regular, moisture or mold resistant, abuse resistant, fire rated core), and thickness match between drawing and specification? |
| Framing | Partition detail + framing and gauge requirements | Are stud spacing, gauge, and track requirements identifiable for the assembly and consistent with any referenced tested design? |
| Fire rating basis | Life-safety or rating plan + tested-assembly reference | Does the assembly reference an identifiable tested design, and do the drawings and specification cite the same one? |
| Sound rating | Acoustic notes + sound-rated assembly clauses | Is there a documented basis, such as insulation, resilient channel, or perimeter sealant, for the sound performance shown on the plan? |
| Head-of-wall and perimeter | Reflected ceiling plan or section + perimeter and deflection clauses | Are top-of-wall conditions, deflection tracks, and fire-rated perimeter details identified consistently for the same partition type? |
| Joint treatment | Finish schedule + joint-treatment level clauses | Does the specified finish level match the intended visible or concealed condition for the wall? |
| Openings and penetrations | Door and window openings, MEP penetrations + firestopping clauses | Are ratings preserved at openings and penetrations, with the required accessories and firestop systems referenced? |
Avoid a false conflict
A shared partition tag does not guarantee a shared rating, and two different tags can still call for compatible board types. Confirm the tested-assembly reference and its exact layer, framing, and perimeter requirements before treating two walls as equivalent.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
Where Groundbook fits
Groundbook’s drawing and specification review helps investigate potential disagreements in the documents you supply. Include the relevant specification sections and drawing references, then verify the cited evidence with the responsible reviewers before acting on a finding.
