GCC Blueprint Reading & Specifications 2 — Questions and Answers
Question 1: On a structural drawing, what does a dashed hidden line typically represent?
- A dimension line
- An edge or feature not visible from the current view (Correct answer)
- A centerline for symmetry
- A section cut indicator
Correct answer: An edge or feature not visible from the current view
Hidden lines (dashed) show edges or features that exist behind or beneath the surface visible in that view.
Question 2: Which CSI MasterFormat division covers Concrete?
- Division 02
- Division 03 (Correct answer)
- Division 04
- Division 05
Correct answer: Division 03
CSI MasterFormat Division 03 is dedicated to Concrete, covering cast-in-place, precast, and related work.
Question 3: What is the purpose of a 'detail drawing' on a set of construction plans?
- To show the overall site layout
- To provide an enlarged view of a complex area for clarity (Correct answer)
- To list all materials and quantities
- To illustrate the electrical riser diagram
Correct answer: To provide an enlarged view of a complex area for clarity
Detail drawings are enlarged-scale views that clarify complex connections or assemblies that cannot be clearly shown at standard plan scale.
Question 4: A specification section written in the 'closed' format means:
- Only one acceptable manufacturer is listed
- The bidder must use the exact product specified with no substitutions (Correct answer)
- The section is sealed and cannot be opened during bidding
- Alternate bids are required
Correct answer: The bidder must use the exact product specified with no substitutions
A closed specification names one specific product or system and does not allow substitutions, unlike open or performance specs.
Question 5: On a floor plan, what do the letters 'FF&E' typically refer to?
- Foundation, Framing, and Earthwork
- Furniture, Fixtures, and Equipment (Correct answer)
- Fire protection, Fuel, and Electrical
- Finish Floor Elevation
Correct answer: Furniture, Fixtures, and Equipment
FF&E stands for Furniture, Fixtures, and Equipment — items often shown or scheduled on architectural plans but not permanently attached to the building.
Question 6: What does a 'north arrow' on a site plan indicate?
- The direction of water drainage flow
- True or magnetic north for orientation of the drawing (Correct answer)
- The location of the nearest utility connection
- The prevailing wind direction
Correct answer: True or magnetic north for orientation of the drawing
A north arrow orients the drawing on the site relative to true or magnetic north so the viewer can understand the property's geographic orientation.
Question 7: In blueprint reading, what is a 'reflected ceiling plan' used to show?
- The structural framing above the ceiling
- Ceiling layout, lighting, sprinklers, and HVAC grilles as seen looking up (Correct answer)
- The roof drainage plan
- Reflected changes from an earlier revision
Correct answer: Ceiling layout, lighting, sprinklers, and HVAC grilles as seen looking up
A reflected ceiling plan (RCP) shows what would be seen if a mirror were placed on the floor looking up, displaying ceiling elements and MEP equipment locations.
