Question 1

basement waterproofing vs dampproofing

Answer 1

waterproofing: control water and moisture when hydrostatic pressure is present
dampproofing: no hydrostatic pressure present

Question 2

hydrostatic pressure

Answer 2

force the water in the soil exerts onto your foundation

Question 3

soil treatment ways (7)

Answer 3

drainage, fill (remove undesirable soil and fill with new, engineered soil brought in), compaction, densification, surcharging, mixing, geotextiles

Question 4

surcharging

Answer 4

preloading of the ground with fill material to cause it to consolidate and settle - increases bearing capacity of soil or decreases settlement of soil

Question 5

retention pond

Answer 5

prevents excessive stormwater runoff by temporarily holding it and releasing it at a controlled rate

Question 6

bioswale

Answer 6

allow sediment to settle while water drains

Question 7

infiltration basin

Answer 7

retains sotrmwater until it seeps into the ground

Question 8

proxemics

Answer 8

territorialitym spacing and positioning between people, and organization of the environment

Question 9

stand-off distance

Answer 9

space between building and potential location of blast theart

Question 10

gross area formula

Answer 10

efficiency ratio

Question 11

minimum sidewalk width

Answer 11

5ft

Question 12

active solar system needs:

Answer 12

requires collector, storage device, and distribution system

Question 13

water table

Answer 13

elevation below which the soil is water-saturated

Question 14

geotechnical report info (7)

Answer 14

stability, strength, compaction characteristics, drainage characteristics, organic content, plastic limit, and overal content of earth

Question 15

brownfield site

Answer 15

site that is confirmed or suspected to be contaminated

Question 16

angle of repose

Answer 16

steepest angle that the side of an excavated area can be before soil backslides into the pit

Question 17

soldier beam

Answer 17

wide-flanged steel beams driven into the soil - wood boards (lagging) are placed between the beams - shoring system

Question 18

soil mixing

Answer 18

before excavating, make walls by mixing cement and water with soil in consecutive columns creating a retaining wall for the excavating site

Question 19

cross-lot bracing vs rakers

Answer 19

cross-lot bracing goes all the way across the excavation

rakers go only part way and terminate at the earth

Question 20

tie-backs

Answer 20

secure into the earth by groud - steel roads and cables inserted - anchor in the earth and a waler

Question 21

shallow frost-protected footing

Answer 21

extending insulation down into the earth

Question 22

floating foundation

Answer 22

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

Question 23

foundation for earthquakes (3)

Answer 23

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

Question 24

caisson vs pile

Answer 24

caissons are drilled and then filled with concrete

piles are hammered in - use when there is no cohesive soil

Question 25

pile cap

Answer 25

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

Question 26

helical pile

Answer 26

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

Question 27

underpinning

Answer 27

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

Question 28

underpinning ways (3)

Answer 28

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

Question 29

provide capillary break in the soil (2)

Answer 29

drainage mat or gravel fill

Question 30

provide waterproofing

Answer 30

sheets, liquid-applied barriers, or special concretes

Question 31

integral waterproofing

Answer 31

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

Question 32

fundation over budget (3 ways)

Answer 32

foundation below water table deep foundation bc of structural geometry foundation interferes with neighboring foundation

Question 33

earth reinforcing (alternative to retaining wall) (2)

Answer 33

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

Question 34

ALTA survey vs Topo surver

Answer 34

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

Question 35

zoning ordinance vs variance

Answer 35

zoning ordinance is a rule variance is an exception to the rule

Question 36

right-of-way vs easement

Answer 36

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)

Question 37

first-right-of-refusal

Answer 37

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

Question 38

step-back vs setback

Answer 38

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

Answer 39

1:50
