NCARB Project Development and Documentation 2 — Questions and Answers
Question 1: Which type of specification writing method gives the contractor the most flexibility in material selection while still ensuring performance outcomes?
- Prescriptive specification
- Performance specification (Correct answer)
- Proprietary specification
- Descriptive specification
Correct answer: Performance specification
Performance specifications define required end results and measurable criteria rather than specific materials or methods, allowing contractors to propose alternative solutions that meet the performance goals.
Question 2: A window schedule on construction documents should include all of the following EXCEPT:
- Rough opening dimensions
- Glass type and U-factor
- Hardware finish
- Unit cost and quantity takeoff (Correct answer)
Correct answer: Unit cost and quantity takeoff
Window schedules are a technical documentation tool and do not typically include cost or quantity takeoff data, which are the contractor's responsibility during bidding.
Question 3: According to ASHRAE 90.1, which building envelope component has the most significant impact on overall thermal performance in a cold climate (Climate Zone 6)?
- Roof assembly R-value
- Window-to-wall ratio and glazing U-factor (Correct answer)
- Foundation insulation
- Interior partition thermal mass
Correct answer: Window-to-wall ratio and glazing U-factor
In cold climates, glazing typically accounts for the greatest heat loss per unit area; ASHRAE 90.1 prescribes strict U-factor and SHGC limits for fenestration to manage this dominant thermal load.
Question 4: When preparing construction documents for a phased project, which drawing should be issued first to allow early site work to begin?
- Architectural floor plans
- Civil and grading drawings (Correct answer)
- MEP coordination drawings
- Interior finish plans
Correct answer: Civil and grading drawings
Civil and grading drawings govern site preparation, earthwork, and utilities — activities that must be completed before the building structure is erected, so they are released first in a phased project.
Question 5: In the context of structural documentation, a general structural note stating 'All concrete to be 4,000 psi minimum compressive strength' is an example of:
- A performance specification
- A keynote
- A general note (Correct answer)
- A material schedule
Correct answer: A general note
General notes appear on drawing sheets and apply broadly to an entire set of documents or system, providing global requirements that govern materials or methods throughout the project.
Question 6: Which document takes legal precedence over others in the event of a conflict during construction?
- The project manual (specifications)
- The architectural drawings
- The addenda (Correct answer)
- The general conditions of the contract
Correct answer: The addenda
Addenda are issued after the original documents and before contract execution, and as the most recently issued documents they take legal precedence over earlier drawings and specifications.
Question 7: A large-scale wall section at 1½" = 1'-0" is primarily used to communicate:
- Overall building massing and proportion
- Room-by-room spatial relationships
- Specific material thicknesses, layers, and assembly details (Correct answer)
- Structural load paths and gravity systems
Correct answer: Specific material thicknesses, layers, and assembly details
Large-scale wall sections (1½" = 1'-0" or larger) are used to show the precise construction of wall assemblies, including individual material layers, thicknesses, insulation, and connections.
