Question 1

What is the first step a fence contractor should take before digging post holes at any job site?

Accepted Answer

Call 811 to have underground utilities located

Answer

Calling 811 before digging is required by law in all 50 states; utility locators will mark underground lines to prevent dangerous and costly strikes.

Question 2

When laying out a straight fence line across a level lot, which tool is most commonly used to establish a true, consistent line?

Accepted Answer

A mason's string line stretched between stakes

Answer

A taut mason's string line stretched between corner or end stakes provides a continuous visual reference to keep all line posts in perfect alignment.

Question 3

For accurate fence post spacing, measurements should be taken:

Accepted Answer

On-center (center of one post to center of the next)

Answer

On-center measurement ensures consistent panel and rail lengths regardless of post width, which is the standard method used in fence layout.

Question 4

On sloped terrain, which fence installation method allows the fence rails to follow the natural contour of the ground?

Accepted Answer

Raking (parallel/contour) method

Answer

The raking method angles the rails to run parallel with the slope, allowing the fence to follow the ground contour without gaps beneath the bottom rail.

Question 5

When installing fence posts in expansive clay soils, what precaution helps prevent post heaving?

Accepted Answer

Over-excavate the hole and backfill with gravel or concrete

Answer

Over-excavating and replacing expansive clay with compacted gravel or concrete reduces moisture-driven soil expansion that can push posts upward.
