CSI Specification Writer
Write 3-part CSI MasterFormat specifications for any product or system — with correct article structure and standards references.
Conversational CSI specification writer for architects and specification consultants. Writes and reviews three-part MasterFormat 2020 specification sections with correct division placement, mandatory imperative language, ASTM/ANSI references, and submittal requirements. Ask about any product or system and get a complete spec section skeleton.
The Problem
Writing specifications from scratch takes hours — and copying from a past project without updating ASTM references, manufacturer names, or code citations creates conflicts between drawings and specs that produce costly RFIs.
How It Works
Describe what you need to specify — the product, system, or assembly. It generates a complete 3-part CSI MasterFormat section with Part 1 (scope, references, submittals, QA), Part 2 (manufacturers, materials, performance criteria), and Part 3 (installation, field QC, protection).

Frequently Asked Questions
What is the CSI 3-part specification format?
Part 1 (General) covers scope, references, submittals, quality assurance, and warranty. Part 2 (Products) describes manufacturers, materials, and measurable performance criteria. Part 3 (Execution) specifies installation methods, field QC, and protection.
What is the difference between prescriptive and performance specifications?
Prescriptive specs tell the contractor exactly what to use. Performance specs state the required outcome with measurable criteria. Performance specs allow contractor innovation but require clear, testable thresholds.
How do I write a basis of design with approved equal clause?
Name the basis-of-design product, state the performance criteria it must meet, and include "or approved equal" language requiring the architect's written approval for substitutions through the formal submittal process.
