Sample NV B-6 Commercial Remodeling Practice Questions

Try these sample questions to test your NV B-6 Commercial Remodeling exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Per ACI 318-14 Table 20.6.1.3.1, what is the specified concrete cover for cast-in-place nonprestressed reinforcement that is cast against and permanently in contact with the ground?
A.3 inches
B.2 inches
C.1-1/2 inches
D.3/4 inch
Explanation: ACI 318-14 Table 20.6.1.3.1 requires 3 inches of specified cover for all bar sizes when concrete is cast against and permanently in contact with the ground. That cover keeps soil moisture and chemicals off the steel. Smaller covers in the same table apply only to formed concrete that is not cast against earth.
2A B-6 crew is placing an interior concrete topping. Per ACI 318-14 Section 26.12.2, samples for strength tests of each mixture placed each day shall be taken at least once a day, once for each 5,000 square feet of slab or wall surface, and at least once for each:
A.50 cubic yards of concrete
B.75 cubic yards of concrete
C.150 cubic yards of concrete
D.300 cubic yards of concrete
Explanation: ACI 318-14 Section 26.12.2 requires strength-test samples of each mixture at least once each day, at least once for each 150 cubic yards, and at least once for each 5,000 square feet of slabs or walls. The most frequent of those three triggers governs the sampling rate.
3Unless the contract documents specify otherwise, how long should ordinary portland-cement concrete for an interior remodel topping be kept moist after finishing?
A.Not less than 7 days
B.Until the bleed water disappears, then uncovered
C.24 hours, then the slab may dry freely
D.28 days of continuous ponding only
Explanation: ACI 318 construction requirements and ACI 308 practice keep ordinary concrete continuously moist for at least 7 days so hydration can develop specified strength and limit early shrinkage cracking. High-early-strength cement may use a 3-day moist cure when the documents allow it. Bleed-water disappearance only marks the start of finishing, not the end of curing.
4An interior commercial remodel specifies a 1-1/2-inch concrete topping over a 28-foot by 22-foot room. Allowing 8 percent waste, how many cubic yards should be ordered?
A.2.4 cubic yards
B.2.6 cubic yards
C.2.8 cubic yards
D.3.1 cubic yards
Explanation: Volume is 28 ft × 22 ft × (1.5 ÷ 12) ft = 77 cubic feet. Dividing by 27 cubic feet per cubic yard gives 2.85 cubic yards neat. Adding 8 percent waste is 2.85 × 1.08 = 3.08, which rounds to a 3.1-cubic-yard order. Ready-mix is ordered to the next practical tenth so the pour is not shorted.
5IBC 2012 Section 1907.1 requires a vapor retarder under an interior concrete floor slab on ground. What is the minimum polyethylene thickness and the minimum joint lap stated in that section?
A.6-mil polyethylene lapped not less than 6 inches
B.4-mil polyethylene lapped 4 inches
C.10-mil polyethylene lapped 2 inches
D.15-pound felt lapped 12 inches
Explanation: IBC 2012 Section 1907.1 requires a 6-mil polyethylene vapor retarder with joints lapped not less than 6 inches between the base course or subgrade and the concrete floor slab, or another approved equivalent. The retarder limits moisture drive into interior finishes. Four-mil film and 15-pound felt are not the IBC 2012 slab vapor-retarder specification.
6For a non-loadbearing interior masonry partition in a commercial remodel with ordinary exposure, which ASTM C270 mortar type is the general-purpose choice?
A.Type N
B.Type M
C.Type K
D.Type O only, with no alternatives
Explanation: ASTM C270 Type N is the general-purpose mortar for above-grade interior and exterior walls with ordinary loading. Type M is a high-compressive mix used for high loads or severe frost exposure. Type O is a low-strength interior mortar, and Type K is an older restoration mix, not a current C270 workhorse for new commercial partitions.
7Per ACI 530.1 / TMS 602, cleanouts are required at the bottom of grout cells when the grout pour height exceeds:
A.32 inches
B.4 feet 0 inches
C.5 feet 4 inches
D.8 feet 0 inches
Explanation: ACI 530.1 / TMS 602 requires cleanouts when the grout pour height exceeds 5 feet 4 inches so mortar droppings can be removed and the cell inspected before grout is placed. Low-lift grouting at or below that height may proceed without cleanouts. The 32-inch figure is a common horizontal cleanout spacing in solid-grouted work, not the pour-height trigger.
8ACI 530 / TMS 402 treats masonry as laid in running bond when the overlap of units in successive courses is at least:
A.One-eighth of the unit length
B.One-half of the unit length, with no lesser overlap permitted
C.One-fourth of the unit length
D.The full unit length so head joints align
Explanation: TMS 402 defines running bond as an overlap of at least one-fourth of the unit length. Typical half-bond exceeds that minimum. Any pattern with less than one-fourth overlap, including stack bond, is “other than running bond” and needs the extra horizontal joint reinforcement the code requires for that condition.
9How many nominal 8-inch by 8-inch by 16-inch concrete masonry units are required for a 24-foot-long by 8-foot-high interior partition, counting only full-face units and ignoring openings and waste?
A.216 units
B.192 units
C.168 units
D.144 units
Explanation: Each 8-by-16-inch face covers 8/12 × 16/12 = 8/9 square foot, so 1.125 units cover one square foot. Wall area is 24 × 8 = 192 square feet; 192 × 1.125 = 216 units. Equivalently, there are 12 courses (8 ft ÷ 8 in.) and 18 units per course (24 ft ÷ 16 in.), and 12 × 18 = 216.
10What are the actual specified dimensions of a nominal 8-inch by 8-inch by 16-inch concrete masonry unit?
A.8 inches by 8 inches by 16 inches
B.7-1/2 inches by 7-1/2 inches by 15-1/2 inches
C.7-3/4 inches by 7-3/4 inches by 15-3/4 inches
D.7-5/8 inches by 7-5/8 inches by 15-5/8 inches
Explanation: Standard CMU are manufactured 3/8 inch smaller than nominal in each direction so a 3/8-inch mortar joint produces the modular 8-inch and 16-inch layout. A nominal 8×8×16 unit is therefore 7-5/8 × 7-5/8 × 15-5/8 inches. Using the nominal size in a takeoff without mortar will short the wall.
