Utah-Excavating, Grading, Trenching and Septic Tanks Online Practice Test

These are actual questions from our online practice test.

We have included a question from each chapter of the test. Every question will be multiple choice. The answers are not included with the sample.

Sample Questions

# Chapter Title Question
1 Earthworks, Excavating, Drainage, Compaction and Surveying What is the most critical aspect of subsurface survey?
2 Excavating, Sitework and Removal The minimum depth that all stumps should be cleared away in embankment areas is what?
3 Excavating and Grading

Road design, through its elements such as template (width, full bench/side cast), curve widening and grade affect the potential for erosion. Erosion rates are directly proportional to the total exposed area in cuts and fills. Road cuts and fills tend to increase with smooth, horizontal and vertical alignment. Short vertical and horizontal tangents tend to reduce cuts and fills. Erosion rates can be expected to be lower in the latter case. Prior to the design phase it should be clearly stated which alignment, horizontal or vertical, takes precedence. If the tag line has been located at or near the permissible maximum grade, the vertical alignment will govern. Truck speeds in this case are governed by grade and not curvature. Therefore, horizontal alignment of the center line can follow the topography very closely in order to minimize earthwork. Self balancing sections would be achieved by shifting the template ___________________.

4 Grading and Contours The standard drain field for the pressure distribution system consists of perforated pipes, which are _____________ in diameter.
5 Excavating, Grading, Compaction, Soils, Cleaning Worksite and Drainage

The term dry dam refers to a dam that serves purely for flood control without any conservation storage.

8 Plumbing, PSI, Water Pressure, Water Flow, Pipelines and Water Pressure The size of any required water supply pipe depends on what?
9 Septic Tanks Prior to clearing critical grading jobs, it may be necessary to have a _____________ sample and inspect the material and construction site soils.
10 Sewer Installation, Pipe Lines, Leach Fields and Septic Tank Sewer line connections to existing lines or manholes are not made until upstream lines have been _____________.
11 Sewer System, Location Sites, Soil Conditions and Septic Tanks Prior to clearing critical grading jobs, it may be necessary to have a _____________ sample and inspect the material and construction site soils.
