Prep & Study Guide
1.
A proposed commercial building is four stories above grade plane and contains
mixed retail and office uses. Which Iowa code is generally the primary building-
code basis for plan review?
A. International Residential Code
B. International Building Code
C. International Plumbing Code only
D. International Existing Building Code only
Answer: International Building Code
,Rationale: Iowa's State Building Code uses the International Building Code as
the general code for commercial buildings and residential buildings outside the
IRC's scope. Detached one- and two-family dwellings and qualifying townhouses
are instead addressed under the IRC.
2.
Under Iowa's adopted scope provisions, which project is generally eligible for
treatment under the residential code rather than the general IBC provisions?
A. A six-story apartment building
B. A four-story townhouse complex without qualifying separate means of egress
C. A detached two-family dwelling not more than three stories above grade plane
D. A five-story mixed-use building
Answer: A detached two-family dwelling not more than three stories above
grade plane
Rationale: Iowa's amended IBC scope specifically excludes qualifying detached
one- and two-family dwellings and certain townhouses not more than three
stories above grade plane when they have a separate means of egress and
directs them to the IRC.
3.
During preliminary plan review, the examiner determines that a project contains
125,000 cubic feet of enclosed heated space. Which additional energy-review
consideration applies under Iowa requirements?
A. No professional review is ever required
B. Review must be performed by a registered architect or licensed professional
engineer for applicable energy-efficiency compliance
C. Review must be performed only by the electrical contractor
D. Review is required only if the building exceeds 200,000 cubic feet
Answer: Review must be performed by a registered architect or licensed
professional engineer for applicable energy-efficiency compliance
,Rationale: Iowa rules provide that buildings exceeding 100,000 cubic feet of
enclosed heated or cooled space are subject to energy-code plan review by a
registered architect or licensed professional engineer.
4.
A plan examiner receives architectural drawings showing occupancy
classifications but no occupant-load calculations. What is the most appropriate
review action?
A. Approve the plans because occupant load is calculated during inspection
B. Require sufficient information to establish the occupant load and verify egress
requirements
C. Ignore occupant load unless the building has sprinklers
D. Require only the structural engineer's signature
Answer: Require sufficient information to establish the occupant load and verify
egress requirements
Rationale: Occupant load affects exit capacity, number of exits, travel distance,
plumbing fixture calculations, and other code provisions. A plans examiner must
be able to verify those interconnected requirements from the submitted
documents.
5.
A designer proposes an assembly room with 300 occupants but provides only one
exit because the room is equipped with an automatic sprinkler system. What
should the examiner do first?
A. Approve because sprinklers permit one exit in every assembly space
B. Verify the applicable occupancy, occupant load, number-of-exit requirements,
and permitted exceptions
C. Require four exits regardless of occupant load
D. Require the room to be converted to business occupancy
, Answer: Verify the applicable occupancy, occupant load, number-of-exit
requirements, and permitted exceptions
Rationale: Sprinkler protection does not automatically eliminate minimum
egress requirements. The examiner must apply the occupancy-specific provisions
and determine whether any exception permits the proposed arrangement.
6.
Which document is most useful for determining whether a building's proposed
construction type is compatible with its height and area?
A. Door schedule only
B. Code analysis and occupancy/construction-type information
C. Plumbing fixture schedule only
D. Finish schedule only
Answer: Code analysis and occupancy/construction-type information
Rationale: Height and area limitations are evaluated by occupancy, construction
type, sprinkler status, and other applicable factors. A complete code analysis
should make those relationships clear.
7.
A five-story office building is proposed using Type V-A construction. The plans
examiner should primarily compare the proposal against which factors before
determining compliance?
A. Only the floor-to-floor height
B. Occupancy, allowable height, allowable area, construction type, and sprinkler
conditions
C. Only the number of elevators
D. Only the exterior finish
Answer: Occupancy, allowable height, allowable area, construction type, and
sprinkler conditions
