Separate material, labor, equipment, and subcontract scope

Planning workflow

1. Start with a versioned quantity takeoff and coverage report.
2. Attach dated unit costs only to compatible material and package units.
3. Describe labor basis by task, crew, duration, productivity, or actual bid.
4. Add equipment, logistics, subcontractor, overhead, profit, and exclusions as named categories.

Formula or decision logic

Line cost = purchase quantity x material unit cost + labor quantity x labor unit cost + explicit equipment and subcontract amounts. A percentage split may summarize a completed estimate, but should not generate missing labor from material cost unless the source and limitations are clearly documented.

Worked planning example

One flooring scenario has 1,080 sq ft purchase quantity at a dated material fixture of $4 per sq ft. That gives a $4,320 material subtotal only. Installation, preparation, transitions, delivery, tax, and disposal remain separate blank or estimated lines; AtriBuild must not silently call $4,320 the floor cost.

Limitations and review boundary

• Development price fixtures are not market quotes.
• Productivity varies with crew, site, detail, schedule, and conditions.
• Licenses, insurance, taxes, overhead, and contracting terms vary locally.
