What would NOT be allowed in an access floor with removable
panel?
A. plumbing
B. HVAC
C. electrical conduit
D. computer cable - CORRECT ANSWER-A. plumbing
Explanation: Computer cable and electrical conduit are
commonly placed in raised access floors, used below computer
rooms or where equipment must be kept cool. Duct work is also
allowed. Plumbing is not allowed because pipe breaks can cause
problems.
What determines the depth of steel studs in commercial
construction?
,2|Page
A. acoustical rating of the wall
B. the fire rating of the wall
C. the thickness of the gypsum board
D. partition height, gauge of the stud, spacing of studs and
number of layers of gypsum board - CORRECT ANSWER-D.
partition height, gauge of the stud, spacing of studs and number
of layers of gypsum board
Explanation: The most common size of 2 1⁄2′′ for nonstructural
steel framing. This depth is sufficient for normal ceiling heights
and slab to slab partitions. It allows enough room for electrical
boxes and small pipes. The studs are normally placed 16′′ or 24′′
on center.
Where is the junction box for a power pole located?
A. access panel
B. floor
C. plenum
D. circuit breaker box - CORRECT ANSWER-C. plenum
,3|Page
Explanation: Commercial construction includes a plenum space
above finished ceiling for mechanical systems, wiring and other
building services. A J-box for branching or connecting electrical
circuits would be within the plenum space. Wiring is concealed
within a conduit. J-boxes will be exposed or mounted on the
wall or finished ceiling for lighting or other features requiring an
electrical connection.
Which of the following would be used to improve the acoustical
properties of a wall by isolating the wallboard from rigid
attachment to the framing?
A. wood furring strips
B. resilient channels
C. hat shaped furring channels
D. insulation - CORRECT ANSWER-B. resilient channels
Explanation: Resilient channels improve the acoustical
properties of a wall by separating the wall's structure from its
surface material. They make
the wall less stiff, inhibiting the transfer of vibrations through to
the other side.

The transmission loss of a sound barrier can be improved by
constructing it as two separate layers that are not rigidly
interconnected. The air cavity between reduces the stiffness of
the barrier, and improves its ability to block sound. Filling the
void with porous sound‐absorbing material increases the
transmission loss.
Any rigid interconnections decrease performance, and a
common stud wall will perform in a manner similar to a single‐
material wall.
Hat-shaped furring channels are used for ceiling framing and to
fur out from concrete or masonry walls if the walls are uneven
or if additional depth is needed for electrical outlets or
insulation.
Insulation is also plac
Prior to formally submitting drawings for permit, an interior
designer cannot ask a building official to provide opinions or
likely requirements regarding the proposed design.
A: True
B: False - CORRECT ANSWER-B: False
