Which type of slab construction does not have a separate footing?

• A. Floating
• B. Supported
• C. Monolithic
• D. Reinforced

Answer: (C)

Monolithic slab construction is characterized by its design, where the slab and footing are poured simultaneously as a single unit. This method typically creates a continuous slab that rests directly on the ground without requiring a separate footing, which can simplify the construction process and often reduce costs.

In contrast, other types of slab constructions, like floating and supported slabs, involve distinct components where footings are necessary to provide extra stability and support. Reinforced slabs, while they may also be monolithic in nature, specifically refer to the use of steel bars or mesh within the concrete to increase strength. However, the distinguishing factor for monolithic slabs is the lack of separate footings, which makes it the correct choice in this context.
