Question 1
A site plan uses a scale of 1/4 inch = 1 foot. A pool dimension measures 6.5 inches on the plan. What is the actual dimension?
Correct Answer:
26 feet
Explanation:
At 1/4 inch per foot, each inch represents 4 feet. Therefore 6.5 × 4 = 26 feet.
Question 2
Which instrument is most appropriate for transferring a known benchmark elevation to several points around a commercial pool site?
Correct Answer:
Builder’s level with a leveling rod
Explanation:
A builder’s level and leveling rod are used to establish and transfer elevations from a benchmark so excavation, beam, deck, and equipment elevations can be controlled.
Question 3
A geotechnical report indicates a seasonal water table above the proposed deep-end floor elevation. What condition should the contractor plan for before shell construction?
Correct Answer:
Dewatering and control of hydrostatic uplift
Explanation:
Groundwater above the excavation can destabilize the site and create hydrostatic uplift. Dewatering or another engineered groundwater-control method should be planned before shell placement.
Question 4
Before mechanical excavation begins in an area where buried utilities may be present, what is the most appropriate first action?
Correct Answer:
Determine utility locations and contact the utility owners or locating service
Explanation:
The locations of underground utilities that may be encountered must be determined before excavation. Utility owners or the applicable locating service should be contacted before digging.
Question 5
Under OSHA excavation rules, a trench 4 feet or more in depth must have a safe means of egress positioned so an employee travels no more than what lateral distance?
Correct Answer:
25 feet
Explanation:
29 CFR 1926.651(c)(2) requires a stairway, ladder, ramp, or other safe means of egress in trenches 4 feet or more deep so workers need travel no more than 25 feet laterally.
