ICC Permit Technician Practice Exam

During the ___ inspection, the inspector checks the base for material type and thickness, and vapor barrier placement:

1. Foundation

2. Footing

3. Concrete slab-on-grade

4. Framing

The correct answer is: Concrete slab-on-grade

The correct choice is related to the concrete slab-on-grade inspection, which involves verifying various aspects of the concrete placement prior to the slab being poured. During this inspection, the inspector focuses on several critical components, including the type and thickness of the material(s) being used for the slab, as well as the placement of the vapor barrier. The material type is important for ensuring that it meets the structural and durability requirements set by building codes. The thickness is also essential as it can significantly affect the slab's load-bearing capacity and its overall performance. The vapor barrier placement is crucial to prevent moisture from penetrating the slab, which can lead to issues like mold and deterioration of the concrete over time. Thus, this inspection plays a vital role in ensuring the long-term sustainability and integrity of the slab being installed. In contrast, inspections focusing on the foundation or footing would have different specific checks related to the excavation, reinforcement, and anchor placements, while framing inspections would assess the structural elements above the slab. Each of these other types of inspections has their own sets of criteria and components that do not specifically involve the slab-on-grade's material and vapor barrier considerations.
