Advanced Construction-Math Calculator with Trigonometric Functions for Building Pros

Contractors • Engineers
Architects • Draftspersons

The Construction Master® Pro Desktop sets the industry standard.

It’s the most powerful and advanced construction-math calculator ever developed. With many new built-in solutions and expanded preference selection, it is easy to use in the field or office. Get the job done right the first time with fast, accurate answers to construction problems. Perfect for completing layouts, bids and estimates.

Dimensional Math and Conversions
• Work in and convert between all building dimensional formats: Yards, Feet-Inch-Fractions and Metric — including Areas and Volumes.
• D:M:S to Decimal Degree conversions.
• Weight per Volume.

Full Trigonometric Function
• Sine, Cosine, Tangent, Arcsine, Arccosine and Arctangent simplify complex design and construction- math.

Dedicated Functions
• Complete Stair calculations for Risers, Treads, Stringer Length, Incline Angle.
• “Riser Limited” and Stairwell Opening Solutions.
• Built-in Right Angle functions.
• Easy Area and Volume solutions with Length, Width and Height Keys.
• Drywall, Siding and Paneling function calculates 4x8, 4x9 or 4x12 sheets to cover an area.
• Roof Function finds Area, Bundles, Squares and 4x8 Sheathing for flat or pitched roofs.
• Custom Rafter function provides Common Rafters, Regular and Irregular Hips, Valleys and Jacks; cutting angles (Cheek, Level and Plumb).
• Compound Miter — Store Crown Angle and enter Wall Corner Angle to calculate the Blade Tilt and Angle for Miter cuts.
• Jack Rafter results for Regular and Irregular Pitch roof. Find Rake-Wall studs with on-center spacing.
• Advanced solutions for Circles, Arches, Columns/Cones, Pillars, Windows, Post-holes.
• Arched Rake-Walls with on-center spacing.
