TIM 333 Final ExamAccess aisle - ANS-an aisle next to an accessible parking space that allows disabled
individuals to exit and enter vehicles with a device, such as a wheelchair, and travel to
the sidewalk or building entrance
Accessible parking space - ANS-a parking space specifically designed for disabled
persons that meets or exceeds the requirements of the Americans with Disabilities Act
Accessible route - ANS-a route that connects the accessible parking area to an
accessible entrance of the building the parking lot serves. An accessible route should
be a minimum of 36 inches (91 centimeters) wide and have no abrupt surface
transitions (e.g. from sidewalks to streets) or obstructions that would present hazards to
a visually impaired person.
Acrylic - ANS-synthetic material used in making fabric or molded transparent fixtures or
surfaces
Asphalt - ANS-a dark brown or black thermoplastic material refined from petroleum that
is often used in parking lot construction
Bulk continuous filament (BCF) fibers - ANS-continuous strands of fiber that are used to
construct non-woven or tufted carpet
Built-up roof - ANS-a roof system comprising multiple layers of overlapping roofing
materials
Cable elevator system - ANS-an elevator system in which an elevator car moves up and
down with the help of cables and counterweights
Crazing - ANS-fine hairline cracks that form a map-like pattern on the surface of
concrete
Dead load - ANS-a structure's own weight
Delustered - ANS-a process used on nylon carpet to lessen the shine and to give the
surface a duller finish that looks more like wool
Face - ANS-the pile of the carpet
,Face fibers - ANS-yarns that form the pile of the carpet
Face weight - ANS-the measure of a carpet's pile. Equal to the weight of the face fibers
in one square yard of carpet
Flashing - ANS-copper, aluminum, or fiber sheeting that joins the roof covering to the
building structure where the roof meets a wall, chimney, etc.
Hydraulic elevator system - ANS-an elevator system with no cables or counterweights.
Instead, the elevator car is mounted on a giant piston inside a cylinder that extends
underground to a depth equal to the height the elevator will rise.
Leaching - ANS-the subtraction of cementing constituents from cement due to water
migration through the cement.
Live load - ANS-the weight of the people, equipment, furnishings, and so on within a
building
Modacrylic - ANS-acrylic fiber that is less resistant to stains and abrasions
Pile - ANS-the surface of a carpet; consists of fibers or yarns that form raised loops that
can be cut or sheared
Primary backing - ANS-the part of the carpet to which face fibers are attached and
which holds these fibers in place
Roofing felt - ANS-Fiber-filled paper impregnated with asphalt or tar
Secondary backing - ANS-the part of a carpet that is laminated to the primary backing to
provide additional stability and a more secure installation
Single-ply roof - ANS-a roof system using large pieces of roofing material that are
bonded together using heat or chemicals to form a one-piece roof system
Spall - ANS-a surface cavity of a cement slab, caused by corrosion of embedded metals
Staple fibers - ANS-fibers approximately seven to ten inches long that are twisted
together into long strands and used to construct non-woven or tufted carpet
,Subbase - ANS-in parking lot construction, a layer of sand, gravel, crushed stone, or
other granular material that is sometimes placed between a prepared subgrade and the
surface course.
Subgrade - ANS-in parking lot construction, soil that has been prepared and compacted
to support a layer of concrete or asphalt.
Surface course - ANS-a wearing surface for vehicles to drive on, usually made of
concrete or asphalt.
Tensile strength - ANS-the strength to bear longitudinal stress
Thermal imaging - ANS-use of an infrared camera to detect water leaks by identifying
insulations deterioration.
What should an inspector look for when checking a foundation? - ANS-• Cracks through
the foundation wall
• Evidence of water flowing adjacent to the foundation
• Spalling or crumbling concrete
• Moisture penetrating the foundation walls into basement areas
• Foundations are often difficult to inspect and it is impractical to inspect the
underground portion. However, it is essential to inspect the upper portion annually.
• Foundations are traditionally constructed of masonry and/or reinforced concrete
supported by a solid, underground footing
• If firm foundation material is not available at a reasonable depth, it may be necessary
to go deeper by using piles
• Frost walls surround a building in cold climates and are part of the foundation system.
Its primary purpose is to exclude entry of frost into the foundation, and their structural
uses are normally very limited.
• Preventive maintenance on foundations and footings is difficult because they are
mostly hidden and inaccessible
What are some preventive maintenance strategies for a building's structural frame? -
ANS-• Inspecting visible structural members
• Inspecting other building features that might give telltale signs of structural problems
(e.g. cracks in walls, floors, or ceilings)
• Checking doors and windows for proper alignment and closure
• Tightening all connections
• Weatherproofing (including painting) structural elements
, • Maintaining fireproofing materials (Sometimes maintenance on building systems will
result in damage or removal of structural fireproofing)
• Checking reinforced concrete members
• Preserving structural steel members
• Structural frame is thought of as the "skeleton" that provides support for the entire
building. Typically constructed of steel, concrete (reinforced, pre-stressed), and ordinary
or heavy timber
• Structural frame is usually not exposed to view, but can be inspected fairly easily
through access panels and "behind-the-scenes" areas. This inspection should take
place once a year.
What are typical preventive maintenance activities for exterior walls? - ANS-
What is the basic structure of a roof? - ANS-• Composed of a deck and a covering; the
deck is the structural material the covering is placed upon.
• Deck: usually made of wood, metal, or concrete
• Roof system: combination of all the components of the roof that act together to create
a weather and climate barrier for the building
• Common types of roofing materials: asphalt or fiberglass shingles and roll roofing, split
wood shakes, sawn wood shingles, clay and concrete tile, steel and aluminum
• Roofing material will depend on factors such as economics, the shape of the roof,
climate, fire resistance, durability, aesthetics, and even marketing (distinctive color or
shape)
• Primary purpose is to keep water from penetrating the roofing material
• For added protection, roofing felt (a layer of asphalt- or tar-impregnated paper) is
installed directly on the roof's deck
• Built-up roof: When roofs are relatively flat, multiple layers of felt may be sealed
together to form a moisture barrier, then covered with a surface material (often a gravel
washed layer called a ballast) that can reduce damage due to UV rays, provide weight o
hold down insulation materials, and provide a greater degree of fire protection.
• Many flat roofs are built with single-ply roofing: membrane roofing system composed
of large pieces of roofing material that are bonded together using heat or chemicals to
form a one-piece roof system. The roofing material may adhere to the deck by
mechanical means or adhesives.
• A roof's life expectancy depends on the quality of the construction materials, the skill
of the builders, and the effectiveness of the preventive maintenance program
