On the below grid, assume the depth of each point on the grid. The assumed values can range from 1 to 7 meters. Use one decimal point for each depth such as 2.4 or 4,7 meters. The contour lines are giving an indication of the terrain of this large excavation area. Then answer the following questions: 1. Estimate the quantity of excavation of this area, based on the assumed depths on the grid. After excavation the area will be flat surface. The soil of this area is common earth. 2. Select and design the excavation equipment 3. Select and design the hauling equipment (Optimum) 4. Estimate cost and duration of excavation and hauling processes of this area Remarks: Any needed data in your design can be assumed with discussion and justification. The design needs to be supported with clear indication of the tables and equations used. Figure 1: The excavation area. 300 m 150
