Comprehensive and Detailed Explanation From Exact Extract (CSI-based)
CSI distinguishes among several written formats, each with a specific purpose:
UniFormat – organizes information by systems and assemblies (elements) and is commonly used for:
Cost classification and early cost estimating,
Data organization in the programming, schematic design, and design development stages.
MasterFormat – organizes information by work results (trades/products) and is used for:
Project specifications,
Detailed cost information tied to specification sections,
Organizing procurement and construction information.
CSI’s practice guides clearly connect cost classification and data organization in early design with UniFormat, and detailed specifications and later-stage cost information with MasterFormat. Therefore, the correct pair is:
UniFormat and MasterFormat (Option B)
Why the other options are incorrect:
A. OmniClass and UniFormat – OmniClass is a broader classification system for the built environment, not the primary written format CSI assigns to “specifications.” UniFormat is used for cost and systems, but OmniClass is not the standard format for specs.
C. OmniClass and MasterFormat – Again, OmniClass is overarching; it does not replace UniFormat as the main element-based cost classification tool.
D. SectionFormat and MasterFormat – SectionFormat is the internal three-part structure of a specification section (Parts 1, 2, and 3) and is not the format used for cost classification and data organization; that role is assigned to UniFormat.
Relevant CSI references (paraphrased):
CSI Project Delivery Practice Guide – descriptions of UniFormat use for system-based project descriptions and cost planning, and MasterFormat use for work result organization.
CSI Construction Specifications Practice Guide – chapters on MasterFormat, UniFormat, and their roles in specifications and estimating.
