• A1 inch.
• B2 inches.
• C4 inches.

A 120-foot wood fence has three continuous horizontal rail lines. Rails come in 16-foot boards. Each rail line is estimated separately, and no offcuts may be reused between lines. What is the minimum board count, ignoring saw kerf and other waste?

• A15 boards.
• B18 boards.
• C24 boards.
• D30 boards.

A security design selects the smallest opening among the following chain-link fabrics to reduce available handholds and footholds. Which mesh fits that selection?

• A2-inch mesh.
• B1-3/4-inch mesh.
• C1-1/4-inch mesh.
• D3/8-inch mini-mesh.

A double-swing gate has a 20-foot clear opening between posts. The approved layout reserves a total of 6 inches for both hinge offsets and the center gap. What width is required for each of two equal leaves?

• A9 feet 9 inches.
• B10 feet 0 inches.
• C10 feet 3 inches.
• D10 feet 6 inches.

An estimator wants material cost per linear foot for a fence package. Which calculation has the correct units?

• AMaterial cost multiplied by fence length.
• BMaterial cost divided by fence length.
• CFence length divided by material cost.
• DMaterial cost divided by labor hours.

Site information indicates hard rock at the specified posthole locations. Which estimating action best addresses that known condition?

• AKeep the ordinary-soil excavation productivity unchanged.
• BOmit footing materials because rock is present.
• CPrice a suitable rock-excavation method and productivity.
• DReduce embedment before obtaining design acceptance.

An owner proposes adding privacy slats to an existing open chain-link fence. What design issue should the contractor raise before pricing the change?

• AThe slats necessarily reduce the required post strength.
• BThe slats leave the wind demand unchanged.
• CThe slats alone change the site terrain exposure category.
• DThe added solidity can increase wind demand on the system.

For a nonemergency posthole excavation in California, which notification plan meets the ordinary Government Code section 4216.2 timing rule?

• ANotify 811 at least two working days ahead, excluding the notification day.
• BNotify 811 48 clock hours ahead, counting the notification day.
• CNotify 811 one working day ahead if the hole is narrow.
• DNotify 811 after augering begins if no markings are visible.

An approved site-specific fence drawing requires a 36-inch-deep, 12-inch-diameter line-post footing. Unexpected loose fill is found. What should occur before concrete is placed in a proposed shallower hole?

• AApply a one-third-post-length rule without revising the drawing.
• BWiden the shallower hole without obtaining design review.
• CSubstitute higher-strength concrete for the missing embedment.
• DObtain an approved resolution of the changed ground condition.
