Estimator worksheet
- Purchase unit
- one 4 x 8 ft sheet
- Gross basis
- 32 gross square ft per sheet before layout, cuts, openings, edge support, damage, and waste
- Quantity method
- Lay out panel orientation and joints by surface. Gross area divided by 32 is only a lower-bound check; round the reviewed sheet count up after cuts and waste.
- Cost method
- Multiply purchase sheets by the observed per-sheet price. Keep pallet breaks, delivery, tax, clips, blocking, fasteners, and waste as explicit separate inputs.
Scope checks before ordering
- Separate wall, roof, floor, shear, and specialty panel conditions when their ratings or edge requirements differ.
- Review openings and offcut reuse by surface rather than assuming every square foot can be pooled.
Do not merge unlike products
- Do not combine radiant-barrier, premium subfloor, or tongue-and-groove panels.
- Record span rating and exposure classification when shown.
- Normalize pallet pricing only when the panel count is explicit.
Before using a price
Verify the required panel rating, span rating, exposure classification, fastening schedule, edge support, and local stock before ordering.
