When laying out a building, taking two equal measurements of the diagonal corners means that the four corners are:

• not plumb
• not square
• square
• triangles

To be certain that accurate readings are taken, the bubble in the leveling vial of a farm level should be checked:

• after each reading
• before and after each reading
• every hour
• once a day

When one fails to hold the leveling rod up straight, the measurement will be:

• accurate
• inaccurate
• too short
• too small

If Steve is using a builder’s level to lay out a building, the degree reading when the telescope is turned to mark a corner should be:

• 15°
• 30°
• 45°
• 90°

When setting up a tripod and a builder’s level, the leveling screws should be adjusted until the:

• bubble is centered
• leveling rod is level
• plumb bob hits the ground
• tripod is level

If Abby needs to lay out a building using the 3-4-5 method, what measurement is used with 24' and 30' to make a square corner?

• 18'
• 24'
• 30'
• 60'

The person using a laser beam level for surveying knows that the receiver is on the same grade when a signal is seen or heard from the:

• lower sensor
• middle sensor
• rod person
• top sensor

A hidden line that indicates the presence of unseen edges is shown on a drawing by a:

• heavy solid line
• series of dashes
• solid line with arrows
• solid zigzag line

If Matthew needs to use a blueprint view that shows the building as if it were cut in two to see the wall parts, he should look at the:

• elevation views
• floor plan
• scale
• sectional view

When are mechanical drawings used in construction plans?

• after the structure is built
• if a detailed description is needed
• if a general description is needed
• when they are affordable
