Sample AZ ROC Swimming Pools Including Solar Practice Questions

Try these sample questions to test your AZ ROC Swimming Pools Including Solar exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A contractor is estimating the water volume for a rectangular swimming pool measuring 40 feet in length and 20 feet in width. The pool floor has a shallow end depth of 3.5 feet for 10 feet, a uniform transition slope for 20 feet, and a deep end depth of 8.5 feet for 10 feet. What is the total water capacity of this pool in gallons? (1 cubic foot = 7.48 gallons)
A.35,904 gallons
B.26,928 gallons
C.44,880 gallons
D.53,856 gallons
Explanation: To calculate the pool volume, find the average water depth: (3.5 ft + 8.5 ft) / 2 = 6.0 ft. Multiply the pool surface area (40 ft x 20 ft = 800 sq ft) by the average depth (6.0 ft) to yield 4,800 cubic feet. Multiplying 4,800 cu ft by 7.48 gallons per cubic foot yields exactly 35,904 gallons.
2A circular commercial hydrotherapy spa has an inside diameter of 8 feet and a uniform water depth of 3.5 feet. What is the approximate water volume of the spa?
A.1,053 gallons
B.1,316 gallons
C.1,755 gallons
D.2,106 gallons
Explanation: The radius of an 8-foot diameter spa is 4 feet. The surface area is π x r² = 3.14159 x (4)² = 50.265 sq ft. Volume in cubic feet is 50.265 sq ft x 3.5 ft depth = 175.93 cu ft. Converting to gallons: 175.93 cu ft x 7.48 gal/cu ft = 1,315.9, rounded to 1,316 gallons.
3An engineering plan specifies a 6-inch thick pneumatically placed concrete pool shell floor. The surface area of the pool floor is 1,200 square feet. Including an estimated waste factor of 8% for overspray and rebound, how many cubic yards of shotcrete should be ordered?
A.22.2 cubic yards
B.27.0 cubic yards
C.24.0 cubic yards
D.30.5 cubic yards
Explanation: First calculate neat volume: 1,200 sq ft x (6/12 ft) = 600 cubic feet. Convert to cubic yards: 600 / 27 = 22.22 cu yds. Adding 8% waste (22.22 x 1.08) gives 24.0 cubic yards required.
4On a site plan drawing with 1-foot contour intervals, the proposed pool top-of-wall elevation is established at Finish Floor Elevation (FFE) +104.0 feet. Existing grade contours across the pool excavation footprint range from +100.0 feet to +108.0 feet. What site excavation requirement is indicated?
A.The site requires over-excavation only, with zero cut or fill.
B.The pool must be elevated 8 feet above grade on structural steel piers.
C.The site is completely level and requires no earthwork adjustments.
D.The high side of the pool site requires a 4-foot cut and the low side requires retaining wall or fill support for 4 feet.
Explanation: Because existing grade contours span from +100.0 ft to +108.0 ft across the footprint, setting the top of pool wall at +104.0 ft requires cutting down 4 feet on the high side (+108 ft down to +104 ft) and building up/retaining 4 feet on the low side (+100 ft up to +104 ft).
5On a pool mechanical plan, a circular symbol containing the abbreviation 'HRV' located inside the main drain sump symbol represents which critical plumbing component?
A.Hydrostatic Relief Valve
B.High-Rate Valve
C.Hydraulic Return Vent
D.Heater Recovery System
Explanation: HRV stands for Hydrostatic Relief Valve. It is installed in the bottom of the main drain collector pot to relieve rising groundwater pressure under the pool shell when the pool is drained, preventing vessel upheaval.
6A contractor is estimating #4 steel rebar for a pool shell with a surface area of 1,800 sq ft. Steel is specified in a 12-inch by 12-inch grid in both directions. #4 rebar weighs 0.668 lbs per linear foot. Allowing 15% extra for lap splices and waste, what total weight of steel rebar is required?
A.2,405 lbs
B.2,766 lbs
C.1,380 lbs
D.3,180 lbs
Explanation: A 12" x 12" grid in both directions requires 2 linear feet of rebar per square foot of pool surface area. For 1,800 sq ft, total linear feet = 1,800 x 2 = 3,600 LF. Base weight = 3,600 LF x 0.668 lbs/LF = 2,404.8 lbs. Adding 15% for lap splices and waste = 2,404.8 x 1.15 = 2,765.5 lbs, which rounds to 2,766 lbs.
7According to OSHA 1926 Subpart P Appendix B, what is the maximum allowable slope angle for an unshored excavation up to 20 feet deep in Type B soil?
A.34 degrees (1.5:1 slope)
B.53 degrees (0.75:1 slope)
C.45 degrees (1:1 slope)
D.90 degrees (vertical slope)
Explanation: OSHA 1926 Subpart P Appendix B mandates a maximum allowable slope of 1:1 (45 degrees) for excavations in Type B soil. Type A allows 0.75:1 (53 degrees) and Type C requires 1.5:1 (34 degrees).
8During excavation testing for a pool shell in Phoenix, soil samples exhibit an unconfined compressive strength of 0.3 tons per square foot (tsf). Under OSHA 1926 Subpart P Appendix A, how must this soil be classified?
A.Type A soil
B.Type B soil
C.Stable Rock
D.Type C soil
Explanation: Per OSHA 1926 Subpart P Appendix A, cohesive soil with an unconfined compressive strength of 0.5 tsf or less is classified as Type C soil. Type A soil requires >1.5 tsf, and Type B soil ranges from 0.5 to 1.5 tsf.
9When an excavator accidentally over-digs the floor of a pool excavation by 12 inches below the design grade line, how must the over-excavated area be properly remediated prior to placing rebar?
A.Backfill with engineered granular soil compacted in 6-inch lifts to minimum 95% Standard Proctor density, or fill with lean concrete slurry
B.Fill the 12-inch void with loose uncompacted topsoil
C.Leave the over-excavation empty and increase pool water depth by 12 inches
D.Fill the void with organic mulch to absorb groundwater
Explanation: Over-excavated subgrade must be brought back to design elevation using controlled engineered backfill placed in maximum 6 to 8-inch loose lifts and compacted to at least 95% Standard Proctor density (ASTM D698), or backfilled with lean concrete slurry to prevent differential settlement.
10When excavating a pool in an area with a high groundwater table located 2 feet above the proposed pool floor grade, what is the standard engineering technique to prevent side cave-ins and allow dry shotcrete placement?
A.Pour concrete directly into standing water without dewatering
B.Install a continuous perimeter wellpoint dewatering system or gravel sump pits to lower the water table below the excavation floor
C.Increase soil slope to 90 degrees vertical
D.Mix quicklime into standing water until all liquid solidifies
Explanation: A wellpoint dewatering system or perimeter deep sump pump system must be operated continuously to depress the water table at least 2 feet below the excavation subgrade until the pool shell is placed, cured, and ballast weight or relief valves are established.
