  1. CE 453 Lesson 23 Courtesy of Dr. David Carlson, Agronomy at Iowa State University

  2. Earthwork Analysis • Average End Area Method • Consideration for shrinkage • Balance line Considerations • Limit of Freehaul (LFD) • Limit of Profitable Haul (LFH)

  3. CUT FILL

  4. Special Terms • Free haul distance (FHD)- distance earth is moved without additional compensation • Limit of Profitable Haul (LPH) - distance beyond which it is more economical to borrow or waste than to haul from the project • Overhaul – volume of material (Y) moved X Stations beyond Freehaul, measured in sta – yd3, or sta-m3 • Borrow – material purchased outside of project • Waste – excavated material not used in project

  5. Mass Diagram Development • 1) Place FHD and LPH distances in all large loops • 2) Place other Balance lines to minimize cost of movement (theoretical) • 3) Calculate borrow, waste, and overhaul in all loops • 4) Identify stations where each of the above occur

  6. Second, Larger Example
