Terms

Description

Ballast

A heavy material installed over
a roof membrane

to prevent
wind uplift and shield the
membrane from sunlight.


Beam

A structural member, usually
horizontal, that
carries a load
that is applied transverse to its
length.


Brownfield

Real property of which the
expansion, redevelopment, or
reuse may be
complicated by
the presence or potential
presence of a hazardous
substance, pollutant, or
contaminant.


Building Code

Legal requirements designed
to protect the public by
providing guidelines for
structural, electrical, plumbing,
and mechanical areas of a

structure.


Built
-
up Roof (BUR)

A roof membrane laminated
from layers of asphalt
-
saturated felt or other fabric,
bonded together with bitumen
or pitch.


Cast
-
in
-
Place Concrete

Concrete that is poured in its
final location.


Column

An upright
structural member
acting primarily in
compression.


Concrete Masonry Unit
(CMU)

A block of hardened concrete,
with or without hollow cores,
designed to be laid in the
same manner as brick and
stone.


Construction Type

Five broad categories of
construction found in the
International Building Code
that are based on the fire
-
resistive capabilities of the
materials used.


Curtain Wall

An exterior building wall that is
supported entirely by the
frame of the building, rather
than being
self
-
supporting or
load bearing.


Decking

(Not like the deck on
a residential home)

A material used to span
across beams or joists to
create a floor or roof surface.


Egress

Exits or a way out.


Elevated Floor

A floor that is above the level
of the
ground.


EPDM (Ethylene Propylene
Diene Monomer)

A synthetic rubber material
used in roofing membranes.


Exit

That portion of the means
-
of
-
egress system between the
exit access and the exit
discharge or the public way.


Exit Access

That portion of the
means
-
of
-
egress system that leads from
any occupied portion in a
building or structure to an exit.


Exit Discharge

That portion of the means
-
of
-
egress system between the
termination of the exit and a
public way.


Fenestration

All areas (including the
frames) in the building
envelope that let in light,
including windows, plastic
panels, clerestories, skylights,
glass doors that are more than
one
-
half glass, and glass
block walls. A skylight is a
fenestration surface having a
slope of less than 60 degree
s
from the horizontal plane.
Other fenestration, even if
mounted on the roof of a
building, is considered vertical
fenestration.


Hybrid

Something that is the product
of mixing two or more different
things.


Ingress

Entrances or a means to
enter.


Light

Gauge Steel

Thin sheet metal folded into a
stiff shape and used as a
structural member.


Load

Forces or other actions that
result from the weight of
building materials, occupants
and their possessions, and
environmental effects.


Load Bearing Wall

A
structural wall that carries
loads other than its own
weight.


Low
-
Slope Roof

A roof that is pitched at an
angle so near to horizontal
that it must be made
waterproof with a continuous
membrane rather than
shingles; commonly and
inaccurately referred to
as a
flat roof.


Masonry

Brickwork, concrete block
work, and stonework.


Municipality

A city, town, etc. having its
own incorporated government
for local affairs.


Non
-
Load Bearing Wall

A wall that does not carry
vertical load other than its own
weight.


Occupancy Group

A specification that indicates
by whom or how the structure
will be used.


Occupant Load

The number of persons for
which the means of egress of
a building or portion thereof is
designed. (IBC)


Open Web Steel Joist

Open web,
parallel chord,
load
-
carrying members
suitable for the direct support
of floors and roof decks in
buildings.


Pitched Roof

A sloping roof.


Ponding

The collecting of water, as on
a roof, into large puddles or a
pond.


Precast Concrete

Concrete cast and
cured in a
position other than its final
position in the structure.


Reinforced Concrete

Concrete into which steel
reinforcing bars have been
embedded to impart tensile
strength to the construction.


Shore

A prop for preventing sinking
or sagging (noun).

To support
by a shore (transitive verb).


Single
-
Ply Membrane

A sheet of plastic, synthetic
rubber, or modified bitumen
used as a roofing sheet for a
low
-
slope roof.


Slab
-
on
-
Grade

A concrete surface lying upon,
and supported directly by, the
ground
beneath.


Span

The distance between
supports for a beam, girder,
truss, or other horizontal
structural member; to carry a
load between supports.


Spray Polyurethane Foam
(SPF)


Polyurethane foam sprayed in
place on a low
-
slope roof then
covered with a
protective
coating.


Stability

A condition of a frame or
structure in which a slight
disturbance in the loads or
geometry of the structure does
not produce large
displacements or failure
.


Strength

The capacity of a structure to
resist the effects of
loads.


Structural Efficiency

Ratio of the maximum design
load to the weight of the
structure.

N/A

Tilt
-
up Construction

A method of constructing
concrete walls in which panels
are cast and cured flat on a
floor slab then tilted up into
their final
position.


Underlayment

A panel laid over a subfloor or
subsurface to create a
smooth, stiff surface for the
application of a finish.


Welded Wire Fabric (WWF)

A grid of steel wires or bars
welded together at all points of
intersection to form an open
mat. The fabric is designated
by the size of the grid (spacing
of the wires) in inches followed
by numbers indicating the
gauge of the wire in each
direction.
