CSI MasterFormat Mapping

Q: What is CSI MasterFormat mapping?

Mapping takeoff line items to CSI divisions (e.g., Div 31 Earthwork, Div 33 Utilities) so quantities flow to crew assemblies, unit prices, and SOV with evidence links.

Takeoff finds the quantity. CSI gives it a home — Division → crew assembly → unit price → bid. BidSync auto-maps every line with evidence.

Why it matters

Without CSI, quantities float as orphan numbers. With CSI, 4,820 LF of 12" waterline lands in 33 11 00 with correct crew, production rate, and bid tab — auditable.

How BidSync handles it

Extract line items from PDF/DWG (quantity + spec callout).
Map to CSI MasterFormat (Div 31–33 typical for heavy civil) with confidence.
Evidence link to Plan C-302 / Detail W-14 / Spec 33 11 00 — one click to source.
Push to assemblies and SOV — no double entry.

Example

Plan shows 12" DIP, Detail W-14, Spec 33 11 00 → BidSync creates CSI 33 11 00 line, 4,820 LF, 94% conf., evidence trail included.
