Frequently Asked Estimating & Technical Questions
Key formulas, building code standards, and estimating rules for this trade category.
How do construction material calculators account for jobsite waste and offcuts?
Every calculator in our construction silo applies trade-standard waste allowances automatically—10% for parallel deck framing and compacted aggregate bases, and up to 15% for diagonal decking or multi-valley hip roofs—while letting you adjust the waste factor to match your exact site geometry.
Are the lumber and material quantities based on nominal or actual dimensions?
All calculations use actual dressed lumber dimensions under North American softwood standards (for example, a nominal 5/4x6 deck board is calculated at its true 5.5-inch width plus a 0.25-inch drainage gap, yielding 5.75 inches of effective coverage per course).
How is the 100% solids epoxy coverage per gallon determined?
100% solids epoxy does not evaporate during curing, so 1 US gallon (231 cubic inches) covers exactly 1,604 square feet at 1 mil (0.001 inch) thickness. Our calculator divides 1,604 by your target wet film thickness in mils to compute exact resin gallons.
Can I print a material takeoff sheet to send to my lumberyard or supplier?
Yes. Every calculator includes a one-click Print / Export PDF Proposal button that strips away navigation and renders a clean, single-page material order list and cost summary.
