OmniClass Table Lookup & Classification Search
Need to look up OmniClass tables? The platform provides instant lookup access to all OmniClass tables — searchable, browsable, and cross-referenced to MasterFormat and UniFormat.
Looking Up OmniClass Data
Need to look up OmniClass table entries and classifications? The platform provides instant lookup access to the complete OmniClass table hierarchies — searchable, browsable, and cross-referenced to MasterFormat and UniFormat. This isn't a static list — it's a live lookup tool that reflects the latest CSI-approved classifications.
What You're Looking For
When you search for "omniclass lookup" or "omniclass search," you need:
- Current table entries and classifications — from the latest CSI-approved edition
- Search and browse capability — look up by number, title, or keyword
- Cross-references — see how OmniClass connects to the other CSI standards
- Edition tracking — know which edition you're using and what changed
A static list or PDF can't provide all of this. The platform can.
The platform: Live OmniClass Lookup
The Construction Standard provides licensed access to OmniClass through CSI Dynamic Standards. The platform is a live, web-based lookup tool that provides:
Instant Search and Lookup - Search by table number, entry code, or classification keyword - Browse the full OmniClass hierarchy - Filter and sort results - Bookmark frequently-used entries
Always Current - Reflects the latest CSI-approved OmniClass classifications - Updates automatically when CSI publishes changes - No need to hunt for new list versions or wonder if you're current
Cross-Referenced - Cross-reference OmniClass entries to MasterFormat specification sections - Connect OmniClass classifications to UniFormat building elements - Bridge lifecycle classifications across all three standards
Edition-Aware - See what changed between OmniClass editions - Track entry renumbering, additions, and retirements - Know which edition you're using - Avoid edition mismatches across your project team
More Than a Static List
A static OmniClass list — whether in PDF, Excel, or printed format — has critical limitations:
Lists Go Stale OmniClass is updated regularly by CSI. A static list doesn't reflect new editions or addendums. The moment CSI publishes an update, your list is outdated.
No Search Scrolling through a static list or using basic Ctrl+F doesn't compare to searchable, filterable lookup with cross-references.
No Cross-References Static lists don't include governed crosswalks between OmniClass and the other CSI standards. You can't see how classifications connect across the project lifecycle.
No Edition Tracking With a static list, you don't know which edition you have, what changed from prior editions, or whether your list matches your project team's.
