CSI defines specifications (the spec sections in the project manual, typically organized by MasterFormat and SectionFormat) as the written requirements for:
Materials, products, and equipment
Systems and assemblies
Workmanship and installation
Quality, performance, and administrative/procedural requirements related to the work
In CSI’s traditional “drawings vs. specs” distinction:
Specifications primarily describe the qualitative requirements (what quality, what type, what standard, what performance, what procedures).
Drawings primarily show quantitative and dimensional information (how much, how big, where located, configurations and relationships).
Because of this, the correct choice is:
C. Qualitative requirements for products, materials, and workmanship.
Why the other options are incorrect, per CSI usage:
A. All written construction documentsThe project manual may also contain bidding requirements, contract forms, and conditions of the contract, but in CSI terminology, “Specifications” refers specifically to the spec sections, not every written document.
B. All written and drawn construction documentsSpecifications do not include drawings. Drawings are separate contract documents that complement specs; together they define the work, but the term “specifications” is not used to include drawings.
D. Quantitative requirements for products, materials, and workmanshipQuantitative information (dimensions, counts, locations, quantities) is primarily the role of drawings and related schedules, sometimes supported by quantity-related notes. Specifications may include some numbers, but their core function is qualitative and performance-based requirements, not serving as the main vehicle for quantities.
