Steps
Reference CSI MasterFormat Division 09 (Finishes), Section 09 29 00 (Gypsum Board), to structure the takeoff and specification review
Break the takeoff into distinct labor/material phases (framing, hanging, finishing) to isolate cost variances by phase rather than a single lump-sum line
Cross-reference the project's actual specification section number against the MasterFormat edition cited, since section numbers can shift between editions
Quantify board by type, thickness, and fire rating separately, since substitution between types changes both cost and code compliance
Include separate takeoff lines for accessories (corner bead, control joints, fasteners) rather than folding them into board square footage alone
Known gotchas
MasterFormat section numbers can change between edition years; confirm the project spec's stated edition before assuming a section number match
Lumping framing, hanging, and finishing into one estimate line hides which phase is driving cost overruns
Fire- and sound-rated assemblies often require accessories (specific tape, sealant, control joint types) not captured in a generic gypsum board unit price — confirm assembly-specific accessory needs during takeoff
