This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - A mass diagram plots cumulative earthwork, where rising slopes mean cut and falling slopes mean fill. - Balance points on the diagram show where the total cut equals the total fill between two stations. - The difference between free haul (cost included in excavation) and overhaul (paid separately for longer distances). - How to apply the shrinkage factor to calculate the required bank volume from a specified compacted fill volume. - The definition of swell factor and its application in determining hauling capacity for loose soil.
