In a project using back-track loading, the loading time is 2 minutes per scraper, and two scrapers are needed. Calculate the total time taken if the pusher's return time is also 2 minutes. Discuss potential strategies to improve efficiency.
💡 Hint: Focus on both loading and return times!
A construction manager wants to employ shuttle loading on a new site with scrapers moving in both directions. If each scraper costs $100/hour to run, calculate the expected savings in labor costs by reducing wait time by 50% using the shuttle method over ten hours compared to back-track.
💡 Hint: Think about how time translates to cost!
