Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.

Question

### Mass Diagram

**Description:**

The Mass Diagram provides a visual representation of earthwork volumes along a project alignment. It plots the net cumulative yardage of cut and fill against the stations of the project.

#### Diagram Details:
- **X-Axis (Stations):** Represents the stations along the project, ranging from 0 to 25.
- **Y-Axis (Net Cumulative Yardage):** Represents the volume of cut (excavation) and fill (embankment) in cubic yards, ranging from -5000 to 5000 cu. yd.

#### Key Points on the Curve:
- The points where the curve crosses the Y-Axis (net cumulative yardage) at zero indicate a balance between cut and fill.
- Positive values indicate fill (borrow), whereas negative values signify cut (excavation).

#### Specific Points on the Curve:
- Stations 0, 10, and 22 indicate zero net cumulative yardage.
- Station 5 has a net cumulative yardage of -3000 cu. yd.
- Station 7 shows a net cumulative yardage of 1500 cu. yd.
- Station 10 illustrates a peak fill of 3500 cu. yd.
- Between stations 7 and 10, and 16 and 20, corrective actions are taken to balance the fill and cut, indicated by green horizontal lines.

#### Calculation:
Given the Mass Haul Diagram and the following information:
- **Excavation Cost:** $3.50/cu. yd.
- **Borrow Cost:** $3.75/cu. yd.
- **Overhaul Cost:** $1.50/sta*cu. yd.
- **Free Haul Limit:** 600 ft.

The task is to compute the total overhaul cost.

#### Cost Calculation Options:
- $10,590.00
- None of these.
- $1,590.00
- $600.00
- $990.00
