Flashcards in NCIDQ Codes Systems Standards Contracts Deck (66):
Calcium Chloride test
common and inexpensive test method of determining concrete moisture, conducted by placing a standard mass of the referenced material underneath a plastic cover and sealing it to the concrete floor, then measuring the weight of the standard mass after a 72-hr period, also called the 'moisture dome test'
also know as the relative humidity test; moisture of the concrete is assessed by measuring the relative humidity of the air directly adjacent to it.
polyethylene sheet test
a 1.5 foot square of plastic is laid atop the concrete for a period of atleast 16 hours. If condensation forms on the underside of the plastic, it is considered to be unacceptable for resilient flooring.
In a commercial construction projects, wallboards are typically composed of
metal studs with 5/8", 2 1/2 ", 3 5/8", 4", and 6".
Fire rated gypsum wallboard is often referred to as
Electrical Impedance test
Determines the conductance and capacitance of concrete as a means of determining its moisture content.
Performed to gauge the alkalinity of the concrete, which normally has a PH level from 12-13.3. A Special paper strip is applied to the surface of the concrete; in order for resilient flooring to be applied, concrete needs to have a PH no higher than 9.
An igneous rock with visible grains; common colors include gray, beige, white, red, blue, green, and black. Five common finishes include: polished, honed, fine-rubbed, rubbed and thermal.
A metamorphic rock created when ancient shells are melted and mashed into a calcite or dolomite crystalline substance. 4 common finishes: Polished, hined, abrasive and wet-sand.
More popular for exterior use. It is especially porous stone, it is often filled with resin when it is used as flooring.
A fine-grained rock which can be divided easily into long thin slabs suitable for flooring. 3 common finishes: sand-rubbed, honed and natural cleft.
A sedimentary rock composed partly of sand. Is easy to cut into flat thin surfaces suitable for flooring.
Hydrophobic fabric Wallcovering
do not absorb or retain moisture.
Sound transmission Class (STC)
the single-number rating of the ability of an object to dampen the transmission of sound.
Noise reduction Coefficient (NRC)
the single-number average of the coefficients absorption of a given material at 250HZ, 500HZ, 1000HZ and 2000HZ. This average is rounded to the nearest 0.05
the interval required for the sound level in a space to drop by 60 db after the sound source has stopped production.
indicates how well a ceiling absorbs sound coming over a wall.
Ceiling attenuation Class
is the single-number measure of the transmission loss through ceiling tiles between 2 closed rooms if the is no barrier above the suspended ceiling.
the invoice sent by a shipping company
Bill of lading
indicates the contents of a shipment made by a manufacturer or vendor
are the delivered goods as they are described in the sales agrement.
(live loads, dead loads) all of the weight that depends on the structure of a building
is calculated as the total combined weight of people, furniture & moveable equipment
is calculated as the total weight of the building components and immovable equipment
wind and seismic forces exerted
A force that is applied rapidly or that fluctuates a great deal; Example - Cars moving around in a parking garage.
typically placed either at a mullion or perpendicular to a structural wall or column
are placed at the top of a partition in order to compensate for deflection on the floors above.
consideration of the manner in which the detail connected to the substrate; as well as the manner in which the various parts of the detail are connected.
The ability of the detail to withstand the various forces that are likely to be applied to it during its lifecycle
The ability of the detail to maintain its integrity despite movement due to settling, temperature, or humidity.
The ability of a material used in detailing to vary from a given line indicated in the design documents.
The amount of space that has been left to accommodate the placement if a detail.in order for installation to be possible, a design needs to allow enough room for each subsequent element of construction to be added.
Construction trade sequence
The order in which the construction task will be accomplished
The degree to which the designer is responsible for any errors made during detailing.
concrete slab rests atop intermediate beams, which in turn are placed atop larger girders.
Concrete Joist system
Concrete girders are framed into larger beams; the concrete girders are usually between 24 and 36 inches apart.
Flat Plate construction
a concrete slab is placed atop the columns; in situations where floor to floor heights must be kept as small as possible, this type of construction is appropriate
Flat Slab Construction
A concrete slab is placed atop the columns, a drop panel is placed near the column to improve strength.
Waffle Slab Construction
waffle-like concrete slab resting atop columns; sometimes lighting systems are placed directly into the holes.
Drop ship Order
this is completed when the company placing the order wants to have goods shipped to an address other than their own.
