NICET - Highway Construction Inspection Practice Exam

What is a mass haul diagram used for?

1. Calculating water levels

2. Estimating labor costs

3. Graphing the cumulative amount of earthwork moved

4. Designing drainage systems

The correct answer is: Graphing the cumulative amount of earthwork moved

A mass haul diagram is primarily utilized for graphing the cumulative amount of earthwork moved, which is key in understanding and managing the logistics of earthmoving operations on construction projects. The diagram provides a visual representation of the volumes of material that need to be excavated and transported, along with the corresponding distances for hauling. By illustrating the balance between the amount of cut (earth that is removed) and fill (earth that is added), it aids in determining the most efficient hauling routes and scheduling of equipment. This method allows project managers and engineers to optimize operations, reduce costs, and ensure that the project stays on track. The information presented in a mass haul diagram can also assist in predicting whether extra hauling will be necessary or if surplus fill material will be available on-site. While options relating to calculating water levels, estimating labor costs, or designing drainage systems are important aspects of highway construction, they do not accurately represent the primary function of a mass haul diagram.
