The Arizona ROC A-9/B-5/KA-5 exam is a 50-question, 120-minute open-book computer-delivered test administered by PSI Services requiring a 70% passing score. Note: pool equipment is only 8 of 50 questions (16%), so candidates must focus heavily on sitework, rebar, concrete, and shotcrete. The practice bank provided here is an English-language MCQ study adaptation.
Sample AZ ROC Swimming Pools (A-9/B-5/KA-5) Practice Questions
Try these sample questions to test your AZ ROC Swimming Pools (A-9/B-5/KA-5) 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 capacity for a rectangular swimming pool measuring 30 feet in length and 15 feet in width. The pool floor slopes uniformly from a shallow end depth of 3.5 feet to a deep end depth of 6.5 feet. What is the total water volume of the pool in gallons?
2A circular spa/pool has a finished inside diameter of 24 feet and a uniform flat floor depth of 4.5 feet. Using 7.48 gallons per cubic foot, what is the approximate water volume?
3On a pool construction blueprint drawn to a scale of 1/4" = 1'-0", the length of a main pool wall measures 8.75 inches with an architect's scale. What is the actual field dimension of the wall?
4An estimator is calculating concrete volume for a 4-inch-thick pool deck. The overall outer deck boundary is 40 ft by 25 ft, and it encloses an unpaved pool cutout measuring 15 ft by 30 ft. How many cubic yards of concrete are required for the deck (excluding waste factor)?
5A freeform shotcrete pool shell has a total internal surface area (walls and floor) of 800 sq ft and a specified uniform shell thickness of 6 inches (0.5 ft). If the contractor adds a 10% allowance for rebound and waste, how many cubic yards of shotcrete material should be ordered?
6A pool detail drawing specifies top of bond beam (TBB) elevation as +102.50 ft. The deepest pool subgrade elevation at structural floor invert is +94.00 ft. If the engineering plans require 8 inches of compacted aggregate sub-base beneath a 6-inch shotcrete floor shell, what total excavation depth below TBB must be achieved at the deep end pit?
7Per OSHA 1926 Subpart P, how is cohesive soil such as clay, silty clay, or hard caliche with an unconfined compressive strength of 1.5 tons per square foot (tsf) or greater classified?
8During pool excavation, soft unstable organic soil is encountered at the deep end subgrade. What is the standard engineering practice to correct over-excavated or unstable subgrade before placing the pool shell?
9In Arizona, what is the minimum advance notification time required by law to contact Arizona 811 (Blue Stake) before performing pool excavation work?
10What is the primary function of installing hydrostatic relief valves in the main drain sump of a concrete pool shell?
