Sample C-13 Fencing Practice Questions

1A contractor must estimate ready-mix concrete for 10 line post footings, each 12 inches in diameter and 36 inches deep. Including a 15% waste allowance, what total volume of concrete should be ordered?

A.Approximately 1.65 cubic yards of ready-mix concrete.

B.Approximately 2.30 cubic yards of ready-mix concrete.

C.Approximately 3.10 cubic yards of ready-mix concrete.

D.Approximately 1.00 cubic yard of ready-mix concrete.

Explanation: The volume of one cylindrical footing is V = π × r² × h = π × (0.5 ft)² × 3 ft = 2.356 cu ft. For 10 footings, the net volume is 23.56 cu ft. Adding a 15% waste allowance yields 27.1 cu ft, which converts to exactly 1.00 cubic yard (27.1 / 27 = 1.00 cu yd).

2A straight property line fence run measures 200 horizontal feet along a uniform 15% slope grade. What is the actual sloped fencing length required for ordering top rails and fabric?

A.Approximately 191.2 linear feet of fencing material.

B.Approximately 202.2 linear feet of fencing material.

C.Approximately 215.5 linear feet of fencing material.

D.Approximately 230.0 linear feet of fencing material.

Explanation: A 15% slope corresponds to an angle θ = arctan(0.15) = 8.53°. The sloped length equals horizontal distance divided by cos(θ): 200 / cos(8.53°) = 200 / 0.9889 = 202.24 linear feet. Standard estimating practices require slope compensation to avoid material shortages.

3A contractor is installing a 350-foot straight chain link fence enclosure with post spacing at exactly 10 feet on center. How many 50-foot fabric rolls and how many total line posts are required?

A.6 fabric rolls and 36 line posts for the enclosure.

B.7 fabric rolls and 36 line posts for the enclosure.

C.7 fabric rolls and 34 line posts for the enclosure.

D.8 fabric rolls and 35 line posts for the enclosure.

Explanation: Dividing 350 feet by 50 feet per roll yields exactly 7 rolls of chain link fabric. A 350-foot run with 10-foot post spacing creates 35 bays. Excluding the 2 end/terminal posts, the number of interior line posts required is 35 - 1 = 34 line posts.

4A contractor needs dry premixed concrete (60-lb bags yielding 0.45 cu ft each) for 4 terminal posts with 16-inch diameter by 42-inch deep footings. How many 60-lb bags are required?

A.Require exactly 28 bags of dry 60-lb premixed concrete.

B.Require exactly 34 bags of dry 60-lb premixed concrete.

C.Require exactly 39 bags of dry 60-lb premixed concrete.

D.Require exactly 44 bags of dry 60-lb premixed concrete.

Explanation: Footing radius r = 8 in = 0.667 ft, depth h = 42 in = 3.5 ft. Volume per footing V = π × (0.667)² × 3.5 = 4.887 cu ft. Total volume for 4 footings is 19.55 cu ft. Dividing by 0.45 cu ft per bag yields 43.44, which rounds up to 44 bags.

5According to ASTM F567 standard practice for chain link fence installation, what is the maximum allowable post-to-post spacing for commercial line posts?

A.Maximum line post spacing shall not exceed 10 feet.

B.Maximum line post spacing shall not exceed 12 feet.

C.Maximum line post spacing shall not exceed 15 feet.

D.Maximum line post spacing shall not exceed 20 feet.

Explanation: ASTM F567 specifies that line post spacing for industrial and commercial chain link fencing shall not exceed 10 feet on center. Maintaining 10-foot maximum spacing ensures structural resistance against wind loading and fabric deflection.

6Under the California Building Code (CBC 105.2), what is the maximum height a residential boundary fence can be constructed without requiring a building permit?

A.Fences up to 6 feet in height require no building permit.

B.Fences up to 7 feet in height require no building permit.

C.Fences up to 8 feet in height require no building permit.

D.Fences up to 10 feet in height require no building permit.

Explanation: CBC Section 105.2 exempts fences not over 7 feet high from requiring a building permit, unless local municipal zoning ordinances specify lower limits (such as 6 feet in front yards). Contractors must verify local planning guidelines prior to construction.

7Per ASTM F1083 specifications for metallic-coated steel pipe framework, what distinguishes Group IA steel pipe from Group IC high-strength pipe?

A.Group IA is cold-formed steel while Group IC is schedule 80.

B.Group IA is aluminum alloy while Group IC is stainless steel.

C.Group IA is standard Schedule 40 hot-dipped galvanized pipe.

D.Group IA is structural tubing while Group IC is solid bar stock.

Explanation: ASTM F1083 defines Group IA as standard Schedule 40 hot-dipped galvanized steel pipe with minimum yield strength of 30,000 psi. Group IC represents high-strength cold-formed steel pipe with minimum yield strength of 50,000 psi and lighter wall thickness.

8When estimating lumber quantities for a custom cedar privacy fence, what standard waste factor percentage should be added for board cutting and defects?

A.Add a 2% to 3% waste factor for custom cedar fence lumber.

B.Add a 5% to 6% waste factor for custom cedar fence lumber.

C.Add an 8% to 9% waste factor for custom cedar fence lumber orders.

D.Add a 10% to 15% waste factor for custom cedar fence lumber.

Explanation: Trade estimating standards recommend adding a 10% to 15% waste factor for wood fencing. This covers end-trimming, knot cut-outs, warped boards, and natural wood defects during field installation.

9Before establishing fence post placement along a boundary line, what action must the contractor take to verify property lines and avoid encroachment?

A.Review boundary survey maps and locate official property monuments.

B.Align the fence parallel to adjacent existing neighbor fences.

C.Measure from the center line of the nearest paved public street right-of-way.

D.Estimate boundary lines based on existing overhead utility lines.

Explanation: Contractors must locate official property boundary survey monuments (rebar/pins) or rely on a licensed land surveyor's boundary survey. Building on assumed property lines or existing neighbor fences risks costly legal disputes and forced fence removal.

10Under the California Swimming Pool Safety Act (Health and Safety Code §115922), what is the maximum allowable gap between the bottom of a pool enclosure fence and the grade?

A.The bottom clearance gap shall not exceed 1 inch.

B.The bottom clearance gap shall not exceed 2 inches.

C.The bottom clearance gap shall not exceed 4 inches.

D.The bottom clearance gap shall not exceed 6 inches.

Explanation: California Health and Safety Code §115922 and the International Swimming Pool and Spa Code (ISPSC) require pool barrier fences to have a maximum vertical clearance of 2 inches above solid ground (or 4 inches above solid concrete deck) to prevent small children from crawling underneath.
