21
Q

shallow frost-protected footing

A

extending insulation down into the earth

22
Q

floating foundation

A

type of matt foundation - calculate weight of building and weight of soil displace and make them equal

23
Q

foundation for earthquakes (3)

A

series of rubber dampers, hydraulic shock absorbers, and base isolation pads

24
Q

caisson vs pile

A

caissons are drilled and then filled with concretepiles are hammered in - use when there is no cohesive soil

25
Q

pile cap

A

group piles together and top them with a pile cap to distribute the load of the column among several piles

26
Q

helical pile

A

used to shore up existing buildings where excess vibrations associated with ramming piles would be a problem - screwed

27
Q

underpinning

A

improve the foundation of an existing building as part of a renovation/restoration

28
Q

underpinning ways (3)

A

extend the foundation to some deeper strata with more competent supportmake foundation wider so that it rest on more soil, distributing the loadimprove the earth with imported fill or grout

29
Q

provide capillary break in the soil (2)

A

drainage mat or gravel fill

30
Q

provide waterproofing

A

sheets, liquid-applied barriers, or special concretes

31
Q

integral waterproofing

A

use of special admixture that stops up the pores of the concrete

32
Q

fundation over budget (3 ways)

A

foundation below water tabledeep foundation bc of structural geometryfoundation interferes with neighboring foundation

33
Q

earth reinforcing (alternative to retaining wall) (2)

A

compact earth into layers, each with net of steel, plastic, or glass fiber to stabilize the soil, creating a wallnetting to hold back the earth, without wall

34
Q

ALTA survey vs Topo surver

A

ALTA survey shows property lines, improvements, easements, rights-of-way, land ownership conditionstopographical survey measures the contours of the land

35
Q

zoning ordinance vs variance

A

zoning ordinance is a rulevariance is an exception to the rule

36
Q

right-of-way vs easement

A

right-of-way allows someone to pass through someone else’s land (for a sum of money and included in the deed)easement allows other parties to use the land (utilities or environmental reasons)

37
Q

first-right-of-refusal

A

contractually agreed upon that if a property goes up for sale, the person with the first-right-of-refusal can place the first bid

38
Q

step-back vs setback

A

step-back limits a building in height before requiring a step back in plan (allow for light and air in a city)setback is the minimum requirement as to how far a building must be from the road or another building

39
Q

maximum cross slope for ADA ramp

A

1:50

40
Q

fire lanes width

A

20ft

41
Q

liquefaction

A

defines the sudden loss of shearing resistance in a cohesionless soil

42
Q

types of piles

A

steel h pilesteel pipe pileprecast concrete pilewood pile

43
Q

An absorption or drain field in which septic tank effluents seep through loose pipes and coarse aggregates into the surrounding soil.

A

leaching field

44
Q

The 23.5º tilt of the earth’s axis relative to a line perpendicular to the plane of the earth’s orbit.

A

Declination

45
Q

What is waterproofing?

A

This is the control of water and moisture that is subject to hydrostatic pressures. It can refer to the application of watertight membranes, waterstops, or bentonite panels when building below the water table.

46
Q

What is dampproofing?

A

This is the control of water and moisture when hydrostatic pressure is not present.

47
Q

What is Surcharging.

A

this is the act of preloading the ground with fill material to cause consolidation and settlement of the underlying soil. It is used to increase the bearing capacity of soil or to decrease possible settlement, or both.

48
Q

What is a waterstop?

A

this is a preformed piece of material used to seal construction joints. The used of these are a subset to the larger requirement of waterproofing.

49
Q

What is a battered wall?

A

This is a type of retaining wall using a material, such as stones or brick, slightly angled to support the adjacent earth.

50
Q

What is a needle beam?

A

This is a temporary beam (typically made of steel) used to hold up existing structures while work is being done to structural elements or foundations below the structure being supported by the beam. For instance repairing or deepening a foundation.

51
Q

What is the conversion for 1 acre in square feet?

A

1 acre = 43,560 square feet
