Material & Unit Framework
Shared rules for feet, inches, yards, meters, square area, cubic volume, bags, bundles, sheets, pieces, and waste-factor assumptions.
Construction Foundation
Construction Intelligence Foundation
This page documents the shared construction estimation layer used before the individual concrete, roofing, flooring, painting, and landscape calculators are added.
Material and unit framework
Area = length × width
Volume = length × width × depth/thickness
Adjusted Quantity = base quantity × (1 + waste factor)
Estimated Cost = adjusted buying units × unit price + contingency
Volume = length × width × depth/thickness
Adjusted Quantity = base quantity × (1 + waste factor)
Estimated Cost = adjusted buying units × unit price + contingency
Foundation components
Cost Estimate Result Cards
Reusable cost cards that separate quantity, unit price, waste allowance, subtotal, contingency, and practical buying guidance.
Material Quantity Result Cards
Cards for concrete, masonry, roofing, flooring, paint, landscape, and outdoor materials with plain-English interpretation.
Glossary Framework
Short definitions for construction terms such as coverage, waste factor, yield, pitch, grout joint, underlayment, compacted depth, and board foot.
Recommendation Panel
Next-step guidance that routes users to related calculators, warns about assumptions, and reminds users to verify local codes and supplier coverage.
Report Template
A printable estimate format with project area, inputs, assumptions, result, shopping list, safety notes, and review checklist.
Construction glossary
Waste factor
Extra material added for cuts, breakage, overlap, spillage, layout loss, and installation mistakes.
Coverage
The area or volume one unit of material is expected to cover under stated assumptions.
Yield
The practical output from a bag, bundle, roll, gallon, sheet, or batch after mixing or installation assumptions.
Takeoff
A material quantity list prepared from project measurements, drawings, or site dimensions.
Contingency
A cost buffer for price changes, site conditions, delivery fees, and small missing items.
Nominal size
A trade size that may differ from the actual measured size of a construction product.
