Quick rules
- Use safe allowance margins for deadline work.
- Confirm same-day swap capability in advance.
- Route high-risk loads to alternate options when needed.
Input 9 pickup loads for mixed fit-out debris under tight schedule.
Schedule risk plus mixed debris usually favors safer allowance margin.
Material mix, moisture, and included-ton constraints are the most common reason the cheapest option stops being cheapest.
Direct strategy: Use safe recommendation for timeline-critical jobs.
Daily material mix changes make density hard to predict.
Included tons, overage rates, and swap lead time.
Choose safe sizing and lock logistics early.
