Keep your projects aligned with
CSI Dynamic Standards℠
CSI Dynamic Standards℠ combines MasterFormat®, UniFormat®, and OmniClass® into one accessible, efficient, and always-current digital edition. From design through operations, the result is consistent work, fewer requests for information, and less revisions.
Specifiers, architects, engineers, contractors, owners, and facility managers rely on CSI standards every day.
Built for real project work from concept to closeout and beyond
Construction moves fast, and working from outdated references or disconnected systems can slow you down and lead to mistakes. CSI Dynamic Standards gives project teams one trusted, up-to-date source for writing specs, building models, preparing bids, managing assets, or developing software.
Stay current
Work from the latest standards maintained and approved by CSI, with current and past editions easy to access.
Keep pace
Benefit from more frequent updates—across all standards—to keep pace with industry demand. See what changed before updating office masters.
Stay aligned
Empower project teams to use the same structure and language. Keep section lists, keynotes, specs, and handover tags aligned from design through closeout.
Reduce rework
Improve clarity, limit mistakes, and foster better communication among those relying on documents.
Work efficiently
Easily search specifications and reference past editions. Find standards, sections, and classifications in seconds instead of digging through static files.
Remain transparent and accountable
Version history makes it easy to follow edits within MasterFormat, UniFormat, and OmniClass, promoting transparency and accountability.
Fit into your workflow
Use CSI Dynamic Standards in the tools, templates, and systems your team already relies on.
Collaborate seamlessly
One always-current system enables ease of use across teams for better collaboration and communication.
A more efficient way to work with MasterFormat®, UniFormat®, and OmniClass®
Current, connected, and easier to use.
CSI Dynamic Standards brings three essential CSI standards into one connected experience. Unlike static books and PDFs, an online navigational tool enables teams to search standards quickly, move from early design information to detailed specifications, and link to MasterFormat, UniFormat, and OmniClass. Updates come directly and more frequently from CSI, helping your team work from current information and carry it into the tools and workflows you already use.
MasterFormat
Organize specifications and work results with current classifications you can trust. MasterFormat helps teams stay consistent, reduce labeling mistakes, and avoid downstream confusion during bidding, construction, and closeout.
UniFormat
Support planning, estimating, and early design with a structure for elements, systems, and assemblies. UniFormat helps teams carry early decisions forward and connect them to sections as projects move from schematic design (SD) to design development (DD) to the construction documents phase (CD)—without manual remapping.
OmniClass
Organize product, model, and asset information so it works better across design, construction, and operations. OmniClass helps teams deliver cleaner handover information and better data for owners and facility teams.
Applications by Industry
Specifiers
CSI Dynamic Standards empowers specifiers to work with classifications more efficiently. It supports more consistent deliverables, minimizes errors, and improves team collaboration.
Use CSI Dynamic Standards if you/your team:
Writes project manuals or outline specs using MasterFormat® numbers and titles.
Maintains and issues office master sections/templates that embed MasterFormat® numbers and titles on client work.
Produces section schedules/table of contents (TOCs), keynote tables, or submittal logs that reference MasterFormat® sections and shares them with project partners.
Maps early-phase UniFormat® elements to MasterFormat® sections and distributes those mappings externally.
Delivers building information modeling (BIM) data or exports tagged to OmniClass® and UniFormat® for coordination, bidding, or owner handover.
The authorized source for using CSI standards in modern workflows
The Construction Standard is authorized by CSI to provide access to MasterFormat®, UniFormat®, and OmniClass® for today's digital workflows. CSI continues to steward and govern the standards. CSI Dynamic Standards makes them easier to use across project teams, business processes, and software platforms.
Our goal is simple: help teams use trusted CSI standards in ways that support faster decisions, clearer handoffs, and better project coordination from concept through operations.
Licensing: A Simple Rule of Thumb
Licensing:
A Simple Rule of Thumb
If your team uses MasterFormat®, UniFormat®, or OmniClass® in the work you produce, share, publish, maintain, or deliver, CSI Dynamic Standards helps you do that with current, authorized content. One clear firm-wide subscription path gives your organization a practical way to support consistent project information across teams, tools, and deliverables.
If you previously purchased a PDF edition of MasterFormat®, UniFormat®, or OmniClass®, you may continue using that edition only within the scope of the original license. Those legacy PDF rights were granted to a single user only. They were not company-wide, multi-user, transferable, or shareable rights for teams, departments, offices, or enterprise organizations. If more than one person is using the content, or if your organization needs standards access across shared templates, deliverables, workflows, or systems, CSI Dynamic Standards is the appropriate path.
