NCIDQ Construction Documents and Details 1 — Questions and Answers
Question 1: Which drawing type in a set of construction documents typically shows wall types, room names, and door/window locations in plan view?
- Floor plan (Correct answer)
- Reflected ceiling plan
- Elevation drawing
- Section drawing
Correct answer: Floor plan
Floor plans are the primary horizontal cut drawings showing room layout, partition locations, door swings, and fixture placement at approximately 4 feet above finish floor.
Question 2: What does a reflected ceiling plan (RCP) show?
- The ceiling as if reflected in a mirror on the floor, showing lights, HVAC diffusers, and ceiling heights (Correct answer)
- A section through the ceiling structure showing joists and beams
- The floor pattern reflected upward for coordination
- A view looking up from below grade
Correct answer: The ceiling as if reflected in a mirror on the floor, showing lights, HVAC diffusers, and ceiling heights
An RCP is drawn as though a mirror on the floor reflects the ceiling, showing light fixture locations, diffusers, ceiling grid, soffits, and ceiling heights.
Question 3: In construction documents, what is the purpose of a 'keynote' system?
- Referencing materials or conditions on drawings to a numbered list in the specifications or drawing notes (Correct answer)
- Numbering all door hardware sets for the hardware schedule
- Marking structural columns with grid identifiers
- Identifying sheet numbers in the drawing index
Correct answer: Referencing materials or conditions on drawings to a numbered list in the specifications or drawing notes
Keynotes use numbers or letters on drawings that cross-reference to a corresponding list of material or construction descriptions, reducing repetitive notation on plans.
Question 4: What does a 'section drawing' reveal that a floor plan cannot?
- Vertical relationships, ceiling heights, and the interior of wall assemblies (Correct answer)
- Room dimensions and door locations
- Light fixture layout and ceiling grid
- Furniture arrangement and circulation paths
Correct answer: Vertical relationships, ceiling heights, and the interior of wall assemblies
Section drawings cut vertically through the building to show floor-to-ceiling relationships, wall assembly thickness, soffit heights, and the stacking of structural and finish elements.
Question 5: Which drawing convention uses a symbol with a triangle pointing to a wall to indicate an interior elevation drawing?
- Interior elevation reference bubble (Correct answer)
- Door tag
- Revision cloud
- Detail reference symbol
Correct answer: Interior elevation reference bubble
Interior elevation reference bubbles with triangular arrows pointing toward walls indicate that an interior elevation of that wall exists on the referenced sheet and detail number.
Question 6: What is the primary purpose of a 'door schedule' in construction documents?
- Tabulating each door's size, type, material, hardware set, and fire rating in one document (Correct answer)
- Listing the sequence in which doors are installed
- Scheduling the delivery dates of door materials
- Noting acoustic requirements for each door opening
Correct answer: Tabulating each door's size, type, material, hardware set, and fire rating in one document
A door schedule is a table that catalogs every door by number, cross-referencing its dimensions, construction type, finish, frame type, fire rating, and hardware group.
