CONCRETE PLANNING & ESTIMATING
KROB SlabWorks
Plan your slab, work out the materials, and prepare an estimate in one workspace.
KROB SlabWorks helps contractors draw concrete slab layouts, enter dimensions in feet and inches, calculate concrete and material quantities, and price the job. Projects can include customer details, job addresses, notes, and a structure layout.
Created by Cash Robinson, a current Texas A&M University student pursuing a degree in Construction Science, KSW brings together his passion for construction and his background playing baseball. Read Cash’s story.
Slab Workspace
Draw rectangular, L-shaped, and custom slab footprints. Adjust dimensions and see the diagram and quantities update together.
Materials & estimates
Calculate concrete, waste allowances, formwork, gravel, vapor barrier, and reinforcement. Add prices, labor, fees, tax, and markup, then export a PDF estimate.
Structure on grade
Use your slab footprint to place walls, posts, and beams in a 3D grid. Rotate, pan, and zoom to inspect the layout. This is a visual planning feature, not a structural load analysis.
