1A private driveway slab measures 20 feet by 40 feet and is 4 inches thick. How many cubic yards of concrete are required, with no waste allowance?

A.6.0 cubic yards

B.8.9 cubic yards

C.9.9 cubic yards

D.13.3 cubic yards

Explanation: Convert thickness to feet and divide by 27: 20 × 40 × (4/12) ÷ 27 = 266.67 ÷ 27 = 9.88 cubic yards, which rounds to 9.9 cubic yards. Order extra only after the net volume is correct; waste is a separate adder.

2One cubic yard of concrete placed 4 inches thick covers 81 square feet. How many cubic yards are needed for 486 square feet of 4-inch walkway, with no waste?

A.4.0 cubic yards

B.5.0 cubic yards

C.6.0 cubic yards

D.8.0 cubic yards

Explanation: Coverage at 4 inches is 27 ÷ (4/12) = 81 square feet per cubic yard. 486 ÷ 81 = 6.0 cubic yards. The same result comes from 486 × (4/12) ÷ 27.

3A site plan is drawn at a scale of 1/4 inch = 1 foot 0 inches. A walkway measures 3-1/2 inches on the drawing. What is the actual length?

A.7 feet

B.10 feet 6 inches

C.14 feet

D.28 feet

Explanation: At 1/4 inch = 1 foot, each inch on the drawing equals 4 feet. 3.5 × 4 = 14 feet. Equivalently, 3.5 ÷ 0.25 = 14.

4A driveway is 12 feet wide, 50 feet long, and 5 inches thick. If the estimator adds 8 percent waste, how many cubic yards should be ordered?

A.8.6 cubic yards

B.9.3 cubic yards

C.10.0 cubic yards

D.11.1 cubic yards

Explanation: Net volume is 12 × 50 × (5/12) ÷ 27 = 250 ÷ 27 = 9.26 cubic yards. Adding 8 percent: 9.26 × 1.08 = 10.00 cubic yards. Order a full 10-yard load.

5Estimate net concrete for an 80-foot walk that is 5 feet wide and 4 inches thick, plus two landings that are each 5 feet by 5 feet and 6 inches thick. Ignore waste.

A.4.9 cubic yards

B.5.4 cubic yards

C.5.9 cubic yards

D.7.4 cubic yards

Explanation: Walk: 80 × 5 × (4/12) ÷ 27 = 4.94 cubic yards. Two landings: 2 × 5 × 5 × (6/12) ÷ 27 = 0.93 cubic yards. Total = 5.87 cubic yards, which rounds to 5.9 cubic yards.

6A civil grading plan uses a scale of 1 inch = 20 feet. A proposed driveway measures 3.25 inches on the plan. What field length should be laid out?

A.32.5 feet

B.48.8 feet

C.65.0 feet

D.80.0 feet

Explanation: Engineer's scale of 1 inch = 20 feet means 3.25 × 20 = 65 feet. Do not apply an architectural 1/4-inch scale to a civil sheet.

7A rebar takeoff lists 24 pieces of No. 4 bar, each 20 feet long. Using 0.668 pounds per foot for No. 4 bar, what is the mill weight?

A.160 pounds

B.241 pounds

C.321 pounds

D.481 pounds

Explanation: Total length is 24 × 20 = 480 feet. 480 × 0.668 = 320.6 pounds, which rounds to 321 pounds. CRSI nominal weights are used for purchasing and for comparing delivered bundles.

8Under New Mexico Construction Industries rules, which adopted code pair applies to a GS-4 contractor placing a residential garage slab versus a commercial building slab?

A.NMAC 14.7.2 (2021 IRC) for both occupancies

B.NMAC 14.7.3 (2021 IBC) for dwellings and NMAC 14.7.2 (2021 IRC) for commercial

C.NMAC 14.7.3 (2021 New Mexico Residential Building Code / IRC) for the dwelling garage and NMAC 14.7.2 (2021 New Mexico Commercial Building Code / IBC) for the commercial slab

D.Only ACI 318; NMAC does not adopt IBC or IRC

Explanation: NMAC 14.7.3 adopts the 2021 IRC as the New Mexico Residential Building Code for one- and two-family dwellings and their accessory structures. NMAC 14.7.2 adopts the 2021 IBC as the New Mexico Commercial Building Code. A GS-4 contractor must read the correct book for the occupancy.

9A 30-foot by 40-foot pad has an existing grade of 102.4 feet and a proposed subgrade of 101.1 feet. Assuming a level cut over the whole pad, how many cubic yards of excavation are required?

A.44.4 cubic yards

B.52.0 cubic yards

C.57.8 cubic yards

D.75.1 cubic yards

Explanation: Cut depth is 102.4 − 101.1 = 1.3 feet. Volume = 30 × 40 × 1.3 ÷ 27 = 1,560 ÷ 27 = 57.8 cubic yards. Existing above proposed is cut; the reverse would be fill.

10How many cubic feet are in one cubic yard of concrete?

A.9 cubic feet

B.27 cubic feet

C.36 cubic feet

D.81 cubic feet

Explanation: A cubic yard is 3 feet × 3 feet × 3 feet = 27 cubic feet. Every GS-4 quantity takeoff that reports cubic yards divides cubic feet by 27.
