CFP Blueprint Reading & Interpretation 2 — Questions and Answers
Question 1: On a fence blueprint, what does a dashed line typically represent?
- A property boundary
- A hidden or underground element (Correct answer)
- A finished grade line
- A north arrow reference
Correct answer: A hidden or underground element
Dashed lines in blueprints conventionally indicate elements that are hidden from view, such as underground footings or buried conduit.
Question 2: A fence plan shows a 'TYP' notation next to a post spacing dimension. What does 'TYP' mean?
- Temporary placement
- Typical — applies to all similar conditions (Correct answer)
- Top of yield point
- Type of material specified
Correct answer: Typical — applies to all similar conditions
'TYP' stands for 'typical' and means the dimension or detail applies to all similar locations throughout the drawing.
Question 3: Which drawing view shows the fence as seen straight on from the front?
- Plan view
- Section view
- Elevation view (Correct answer)
- Detail view
Correct answer: Elevation view
An elevation view depicts the fence from a perpendicular frontal angle, revealing height, panel design, and vertical relationships.
Question 4: A scale of 1" = 20' is noted on a fence site plan. A drawn fence run measures 3.5 inches. What is the actual length?
- 35 feet
- 60 feet
- 70 feet (Correct answer)
- 7 feet
Correct answer: 70 feet
Multiplying 3.5 inches by the scale factor of 20 ft/inch gives 70 feet of actual fence run.
Question 5: On a structural detail, what does the abbreviation 'BRG' stand for?
- Bearing (Correct answer)
- Bracing
- Boring
- Bridging
Correct answer: Bearing
'BRG' is a standard abbreviation for 'bearing,' referring to load-bearing surfaces or soil bearing capacity in fence foundation details.
Question 6: A site plan includes a north arrow pointing toward the upper-left corner of the sheet. How should you orient your fence layout in the field?
- Align the fence with the sheet's top edge regardless of the north arrow
- Rotate your field layout so true north matches the arrow's direction on the plan (Correct answer)
- Ignore the north arrow as it only applies to architectural drawings
- Flip the plan horizontally before using it in the field
Correct answer: Rotate your field layout so true north matches the arrow's direction on the plan
The north arrow establishes the orientation of the drawing relative to true north, so field layout must match that rotational relationship.
Question 7: What information is typically found in the title block of a fence blueprint?
- Material quantities and unit prices
- Project name, drawing scale, revision date, and drafter's name (Correct answer)
- Soil boring logs and compaction test results
- A list of all subcontractors on the project
Correct answer: Project name, drawing scale, revision date, and drafter's name
The title block contains administrative drawing information including project name, scale, sheet number, revision dates, and the responsible firm or drafter.
