Quantity takeoff is the process of measuring and listing materials and work from drawings and specs so you can price and order them. Done well, it reduces bid risk and supports confident procurement.
Organize by Division and Package
Align takeoffs with your bid packages and CSI divisions (e.g., Div 3 concrete, Div 4 masonry, Div 7 roofing). That keeps quantities in the same structure as your estimate and subcontracts, and makes it easier to hand off to subs or suppliers.
One Source of Truth
Use a single set of documents (drawings and specs) and a consistent method. Note revision dates and exclusions (e.g., “excluding addendum 2 scope”) so everyone knows what was taken off. If revisions hit mid-takeoff, document what’s in and what’s out.
Units and Rounding
Use consistent units (CY, SF, LF, EA, etc.) and rounding rules. That avoids double-counting or missed conversions when quantities feed into estimates or purchase orders.
Document Assumptions
Note assumptions (e.g., “wall height to bottom of joist,” “no deduction for openings under 5 SF”). That helps estimators and subs apply the same logic and reduces disputes later.
Review and Cross-Check
Have someone else spot-check high-value or high-risk items. Cross-check key quantities to plans (e.g., total SF by level) to catch gross errors.
Zeconic delivers quantity takeoff reports by division with clear assumptions and units, so your bids and procurement start from a reliable base. Our CSI coverage includes Div 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 16.
