**Problem 4:**

A new building is planned upon the site shown below. Assume that the clay solids have a specific gravity of 2.67. Find the primary consolidation settlement if the clay is normally consolidated.

**Diagram Explanation:**

The diagram represents a cross-section of the soil layers at the construction site. The site is divided into two main layers:

1. **Sand Layer**:
- Thickness: 8 feet
- Unit Weight (γ): 110 pounds per cubic foot (pcf)
- A water table is present at a depth of 7 feet with a unit weight of submerged sand (γ') of 115 pcf.

2. **Clay Layer**:
- Thickness: 17 feet
- Properties:
- Water content (w) = 34%
- Liquid Limit (LL) = 50%
- Unit Weight (γ) = 120 pcf

An additional load of Δp = 1 kilopascal per square foot (ksf) is applied on the surface. The water table is indicated by a blue dashed line. This setup is used to calculate the primary consolidation settlement for a normally consolidated clay layer.
