How-To Guides
Ten guides: two for each jobsite pain point
Every guide uses current Construction Pro features and screenshots, with explicit units, worked examples, and verification reminders.
Pain Point 1
Feet, Inches & Fractions
Feet, Inches & Fractions
How to Add and Subtract Feet, Inches, and Fractions
Enter mixed construction measurements directly, calculate them without decimal conversion, and read a tape-ready simplified answer.
Feet, Inches & Fractions
How to Convert Decimal Feet to Tape-Measure Fractions
Turn decimal feet or decimal inches into a practical feet-inch-fraction mark, then cycle formats without redoing the math.
Pain Point 2
Rafters & Stairs
Rafters & Stairs
How to Calculate Common Rafter Length and Cut Angles
Use roof pitch and horizontal run to get common-rafter length, plumb cut, and level cut without a multi-step Pythagorean calculation.
Rafters & Stairs
How to Calculate Stair Risers, Treads, and Stringer Layout
Turn total rise into a buildable stair layout with riser count, actual riser height, tread count, and total run.
Pain Point 3
Material Takeoffs
Material Takeoffs
How to Estimate Concrete Bags With Waste
Calculate slab volume, round up to actionable bag quantities, add waste, and avoid a mid-pour material shortage.
Material Takeoffs
How to Estimate Drywall Sheets With Waste and Cost
Convert wall and ceiling area into whole drywall sheets, account for openings and waste, and build a defensible material-cost estimate.
Pain Point 4
Fast Jobsite Use

Pain Point 5
Verify, Save & Share
Verify, Save & Share
How to Check Construction Calculations Before Cutting
Use labeled inputs, diagrams, history, and a repeatable sanity check to catch costly unit or geometry mistakes before material reaches the saw.
Verify, Save & Share
How to Save and Share Calculations and Project Notes
Organize verified math, notes, checklists, photos, and crew handoffs by project so assumptions stay attached to the result.
