NICET - Highway Construction Inspection Practice Exam

What do you typically find at a benchmark location?

1. A wooden hub

2. A known elevation

3. A fill stake

4. A plumb bob setup

The correct answer is: A known elevation

At a benchmark location, you typically find a known elevation, which is critical for construction and surveying tasks. Benchmarks serve as reference points for measuring elevation and vertical distances, providing a reliable and accurate reference in determining the height of structures, grading for roads, or other elevation-related computations. The known elevation can be used to ensure that other construction elements are at the correct height, making it essential for maintaining conformity with design specifications and ensuring proper drainage, stability, and overall safety of the infrastructure. This precise elevation information is vital for engineers, surveyors, and construction workers to ensure that projects are developed accurately and efficiently.
