NICET - Highway Construction Inspection Practice Exam

Which sheets are used to show elevation views of the proposed road?

1. Cross-section sheets

2. Typical section sheets

3. Plan or key sheets

4. Profile sheets

The correct answer is: Profile sheets

Profile sheets are the correct choice for displaying elevation views of the proposed road. These sheets provide a visual representation of the vertical alignment of the roadway, illustrating how the road will ascend or descend in elevation along its length. They typically include critical information such as existing ground elevations, proposed road elevations, and features such as drainage or utilities that may influence the road's profile. On profile sheets, engineers and inspectors can assess the longitudinal changes in grade, which is crucial for design and construction purposes, ensuring proper drainage and safety in road design. By understanding the changes in elevation shown in the profile, construction crews can accurately follow the intended design during the building process. In contrast, cross-section sheets depict a cut-through view of the roadway at specific intervals and do not provide the longitudinal elevation information that profile sheets do. Typical section sheets focus on standard design features and constructions, while plan or key sheets primarily show horizontal layout and alignment rather than elevation details.
