A large-scale earthmoving project requires the construction of an embankment where thousands of cubic metres of common earth (sandy loam) need to be moved from a borrow pit 40 metres away. To achieve the highest possible hourly production output using a single bulldozer, what dozing strategy should be employed?

Question: A large-scale earthmoving project requires the construction of an embankment where thousands of cubic metres of common earth (sandy loam) need to be moved from a borrow pit 40 metres away. To achieve the highest possible hourly production output using a single bulldozer, what dozing strategy should be employed?

Answer options:

• Short pushes with frequent turning to spread the material evenly.
• Aggressive side-casting to quickly dump material from the blade.
• Ripping the material continuously, regardless of consistency. ✅ Utilizing slot dozing to maximize payload per pass.

Correct answer: Utilizing slot dozing to maximize payload per pass.

Explanation: For moving large volumes of material over a 40-metre distance, slot dozing is the most productive technique. The natural containment of the slot walls significantly reduces spillage, allowing the operator to carry more material per pass compared to other dozing methods, thus maximizing hourly output. This is a core HEO productivity technique.
