of a structural steel frame?
LINTELS
__________span from column to column, support intermediate
floors, and help carry wall, partition, and point loads.
GIRDERS
Subfloor may be part of structural frame
TRUE
Which one of the following is not considered a type of slab?
ONE-WAY MOLDED SLAB
If ____________________ is used in light commercial and industrial
buildings and residences, the resulting floor will be acoustically
controlled, fire resistant, free from squeaks and will allow for easy MEP
service.
INTEGRATED DISTRIBUTION FLOOR SYSTEM
Which one of the following industrial floor finishes require
mortar and grout?
TILE
Linoleum is a type of resilient tile
TRUE
The curtain wall is a non-load bearing wal
TRUE
In the cavity wall, _____ wall protects from elements like
rain, wind, snow, etc. from going towards _____ of the
structure.
EXTERIOR, INTERIOR
Lightweight curtain wall can be produced from the following
material(s)
ALUMINUM
Thermal insulation is generally considered to be any material
that has a relatively ___ coefficient of thermal conductivity
LOW
Large fluctuations in temperature change cause expansion and
contraction of the exposed section which causes unnecessary
stresses in the building frame.
TRUE
Heat ducts and water lines do not need an insulation to prevent
heat loss.
FALSE
Heat always seek _____ temperature levels. When the outside
temperature is _____, heat will flow from building to outside.
When the outside temperature is ____, heat will flow through
inside.
LOWER, COOL, HOT

TRUE
Includes cladding, exterior doors and windows, painting, etc
EXTERIOR FINISHING
Partitions, wall finishes, floor finishes, stairs, ceilings, trim around doors, windows,
cabinets fixtures, etc.
INTERIOR FINISHING
Interior finishing cannot start until the building exterior
waterproofing and roofing are complete to prevent water
damage
TRUE
Applied to concrete, masonry, metal lath bases, etc. (rough/extreme wear and tear)
