A soils report has indicated that the water table is 5’ above the basement level of a planned 3 story building. What construction technique will likely be required?
Waterproofing
The assumed height at which work is performed, usually considered to be a desk height, 30in above the floor.
Work plane
The ration of the net glazing area in a room or space (glass only, not including frame or mullions) to the gross exterior wall area
Window to wall ratio
The fraction of visible light that passes through a glazing material
Visible light transmittance
The ratio of the solar heat gain through a fenestration to the total solar radiation incident on the glazing. It’s a value between zero and one.
Solar heat gain coefficient (SHGC)
ASHRAE
American society of Heating, Refrigeration and Air Conditioning Engineers
What is a LAN system
Local area network
What is a WAN system
A WAN is a Wide Area Network
What is an SW type brick, an NW, and a MW?
NW- normal wearing
MW- moderate wearing
SW- severe weathering
What is a reglet
Reglets are horizontal grooves cast into concrete that allow a piece of flashing to be slipped through the brick for proper drainage and moisture control.
What is tuck pointing
Tuck pointing is a process to repair failing mortar joints. The deteriorated mortar is removed to a depth and new, comparable mortar is put in place.
How should metal panels be transported?
Vertically
What is a flitch beam?
A flitch beam combines wood and steel in a sandwich to increase load carrying capacity. They are sometimes called sandwich beams.
The straightest, most uniform grain on board lumber is achieved by specifying…
Rift sawing
What is safing insulation
Fire stop material in the space between floor slab and curtain wall in multi-story construction.
What can be excluded from a foundation waterproofing detail when granular backfill is used?
No drainage board is needed on the exterior
What material contains the most embodied energy
Aluminum
What medium transmits sound the slowest.
- Water
- Steel
- Air
- Concrete
Air
What is the approximate max span of a reinforced concrete waffle slab?
55’
Fluorescent bulbs are primarily filled with what kind of gas?
Mercury
Heavy timber is what construction type?
Type IV
What is the standard corridor width
44”
Fee imposed by a local government within the US on a new or proposed development project to pay for all or a portion of the costs of providing public services to the new development
Impact fee
A lengthwise grain separation in wood between or through growth rings
A shake
A lengthwise separation that occurs through seasoning of wood.
A check
Which of the following soil types is the most thermally conductive?
Saturated sand
Saturated silt
Sand
Clay
Saturated sand
Where is wind energy transfer from a shear wall
The foundation. Lateral loads such as wind are transferred at the foundation of a shear wall.
What is a percolation test used for?
A percolation test is a test to determine the absorption rate of soil for a septic drainfield or “leach field”. The results of a percolation test are required to properly design a septic system.
At what span dimension is a structure considered long span?
There is no set distance at which a structure is considered long span
Aggregate typically occupies what percentage of the total volume of concrete?
65-70%
What is the term for a retaining wall in which the stem and base are connected at intervals by transverse walls?
Counterfort wall

Span/16
Rule of thumb thickness for one way slab.
Max span?
Span/30 for floor slabs
Span/36 for roof slabs
Suitable for spans 6’ - 18’
Slab depth for one way joist slab
Typical spans?
Span/24
Spans typical from 15’ - to 36’
Two way slab and beam slab depth? Two way slab and beam typical spans?
Perimeter/180
Heavy loads from 15’ - 40’
What is a flying form?
Large sections of formwork, including supporting trusses, beams, of r scaffolding that can be moved by a crane in constructing the concrete floors and roofs of multistory buildings.
The word lamella refers to a type of?
Roof structure
Types of moment resisting frames?
IMRF – Intermediate moment-resisting frame
OMRF – Ordinary moment-resisting frame
SMRF – Steel moment-resisting frame
Any carpeting manufactured and sold within the US is required to undergo a special fire test. What is this test called?
Methenamine pill test
What is the purpose of the Steiner tunnel test?
Aka ASTM E84, ul 992, and NFPA 255, it’s used to determine the flame spread rating of finishes for interior walls and ceilings.
