1. What is the primary purpose of a building code?
A. To establish material prices
B. To regulate contractor advertising
C. To establish minimum standards for safe construction
D. To determine project profit
Answer: To establish minimum standards for safe construction
Rationale: Building codes establish minimum requirements intended to protect
occupants, workers, property, and the public through requirements for
structural, fire, electrical, mechanical, plumbing, and other construction
features.
2. Which organization publishes the International Building Code (IBC)?
A. OSHA
B. ICC
C. NFPA
D. ASME
Answer: ICC
,Rationale: The International Code Council (ICC) publishes the IBC and several
other model construction codes used as the basis for state and local building
regulations.
3. Which set of model codes forms part of the North Dakota State Building
Code?
A. IBC, IRC, IMC, and IFGC
B. NEC, NFPA 70E, and OSHA
C. UPC, UMC, and IFC only
D. ASME, API, and ASTM
Answer: IBC, IRC, IMC, and IFGC
Rationale: North Dakota identifies the International Building Code, International
Residential Code, International Mechanical Code, and International Fuel Gas
Code as components of its State Building Code.
4. Who generally has authority to enforce a building code adopted by a North
Dakota jurisdiction?
A. The federal government
B. The jurisdiction that adopted and enforces the code
C. The material supplier
D. The project architect only
Answer: The jurisdiction that adopted and enforces the code
Rationale: North Dakota's Community Services division is responsible for
updating the State Building Code, while enforcement is performed by
jurisdictions that elect to adopt and enforce building codes.
5. What is the primary purpose of a construction drawing?
A. To advertise the contractor
B. To communicate design and construction requirements
C. To calculate payroll
D. To establish tax rates
,Answer: To communicate design and construction requirements
Rationale: Construction drawings provide dimensions, locations, materials,
details, and other information needed to construct the project.
6. What does a scale of 1/4 inch = 1 foot mean?
A. One inch represents one foot
B. One-fourth inch represents one foot
C. Four inches represent one foot
D. One foot represents four inches
Answer: One-fourth inch represents one foot
Rationale: Architectural scales establish the relationship between
measurements on the drawing and actual dimensions in the field.
7. What is the purpose of a foundation?
A. To provide decorative siding
B. To transfer building loads to the supporting soil
C. To ventilate the attic
D. To provide electrical grounding only
Answer: To transfer building loads to the supporting soil
Rationale: Foundations distribute structural loads to the soil while helping
maintain stability and resist settlement and movement.
8. Which condition generally creates the greatest concern for foundation
settlement?
A. Properly compacted soil
B. Uniform bearing conditions
C. Poorly compacted or unstable soil
D. Proper drainage
Answer: Poorly compacted or unstable soil
, Rationale: Unstable or inadequately compacted soil can compress under loads
and cause differential or excessive settlement.
9. What is the primary purpose of reinforcing steel in reinforced concrete?
A. To increase concrete color
B. To resist tensile forces
C. To eliminate curing
D. To reduce excavation
Answer: To resist tensile forces
Rationale: Concrete performs well in compression but has relatively low tensile
strength. Reinforcing steel provides tensile capacity and helps control cracking.
10.Why is concrete curing important?
A. It removes all water immediately
B. It allows proper hydration and strength development
C. It makes reinforcement unnecessary
D. It prevents concrete from hardening
Answer: It allows proper hydration and strength development
Rationale: Proper curing maintains suitable moisture and temperature
conditions so cement hydration can continue and the concrete can develop its
intended properties.
11.What is the primary purpose of a vapor retarder in a building assembly?
A. To increase electrical capacity
B. To control moisture vapor movement
C. To replace structural framing
D. To increase plumbing pressure
Answer: To control moisture vapor movement
