4 cards from this section. Quick, good the night before a test.
Define job efficiency in the context of earthmoving operations.
Think about how much of the hour is used effectively.
What happens to productivity if the soil density is above the standard density?
Consider the physical effort required to move denser soil.
What is the formula for job efficiency?
What ratio compares actual working time and total time?
True or False: High soil density increases productivity in earthmoving projects.
Think about how dense soil would affect loading and pushing.
A bulldozer has an ideal productivity of 150 loose cubic meters per hour on soil with a density of 1365 kg/m³. During a project, soil density is determined to be 1800 kg/m³. Calculate the new productivity adjustment factor.
Recall how to calculate density-based correction factors.
Given an average operations cost per hour of 1200 rupees, with a modified productivity of 65 loose cubic meters per hour, what would be the estimated unit cost per bank meter cube?
Remember, cost per unit connects total cost to work achieved.
