How to Avoid Overestimating Crew Labor Costs
- Track daily material prices and adjust bids with current indexes.
- Break down labor by trade: demolition, plumbing, carpentry, tile for better utilization assessment.
- Include buffer estimates (5–10%) for unknowns like hidden damage or delays.
- Use voice capture or note tools to streamline bid preparation and reduce errors.
Actionable Tools & Professional Tips
- Maintain a labor rate table per trade (e.g., plumber $100–$180/hr, tile specialist $80–$120/hr).
- Utilize spreadsheets for estimating: Task hours × rate = subtotal, plus contingency.
- Apply lean sequencing to avoid idle crew time: demolition, subfloor, plumbing, waterproofing, finishing.
- Document all change-orders immediately to track labor hour shifts.
