BRICK VENEER

Back 3

shall be attached to the wall using wall ties.

Front 4

PERMEABILITY OF THE SOIL

Back 4

is the ability of the soil to allow water to pass through it. Low permeability= Clay High Permeability= gravel, sand.

influence permeability: type of soil and compaction.

not influence permeability: rainfall or shear strength

Front 5

FACTORS THAT IMPACT A GRADING PLAN

Back 5

1- architect design.

2- local municipality.

3- ADA.

4- utility systems.

Front 6

TYPES OF FOUNDATIONS

Back 6

slabs: flat land, continuous walls: can accommodate steeper slopes and piers: less invasive.

Front 7

MAYOR LOAD CARRIERS IN DECKS

Back 7

beams

Front 8

PROPER GRADING DESIGN KEY TASK

Back 8

positive drainage, all within the PL, no runoff going to the adjacent property, no grade changes within trees drip lines, do not take into account the previous use of the site.

Front 9

POROUS PAVING SYSTEM

Back 9

porous asphalt: better for colder climates.

porous concrete: better for arid climates.

precast pavers: not for heavy traffic, better for parking lots and driveways.

Front 10

GREYWATER SOURCES

Back 10

Good sources: showers, sinks and washing machines.

Bad sources: kitchen sink and dishwashers.

Front 11

MIN ELEVATION POINTS IN A PLAN

Back 11

all proposed bldgs on a grading plan should have spots elevations at every corner and an elevation per floor (typ 5 spots elev)

Front 12

CONSTRUCTION JOINTS

Back 12

placed at any time there is a stoppage in the pouring of concrete during construction. (use Dowel bar)

Front 13

CONTRACTION JOINT

Back 13

used to prevent cracking of the concrete.

Front 14

ISOLATION/ EXPANSION JOINT

Back 14

used between two pours of concrete but involves a material that is placed between the two pours the entire depth of the slab.

Front 15

SOIL BEARING CAPACITY

Back 15

1- organic soils have low bearing capacity.

2- it is acceptable to remove the poor soil and replace it with soil that has a greater bearing capacity.

3- driving piles and spread footing is also acceptable.

Front 16

MORTAR

Back 16

a mix of water, cement, and sand. It has high compressive strength and its used to bond masonry units together.

Front 17

SLUMP TEST

Back 17

performed during the pouring of concrete to determine the workability of concrete.

Front 18

PERLOCATION TEST

Back 18

to determine the absorption rate of the soil

Front 19

PROCTOR TEST

Back 19

to determine the bearing capacity of the soil.

Front 20

ACCESSIBLE RAMP

Back 20

min w 36"

min w 48" if making 180-degree turn

min 60x60 if the ramp is changing direction.

Front 21

WORK ON SITE SEQUENCE

Back 21

protect vegetation, remove topsoil, erosion control, clearing, demo

Front 22

ACCESSIBLE WALKWAYS MATERIALS

Back 22

good: concrete and wood.

for wildlife trail: crushed rock, pea sized gravel, bound wood chips, coarse gravel.

Front 23

PHYTOREMEDIATION

Back 23

PROS: aesthetically pleasing, less secondary waste, soil is usable after the treatment, less cost than mechanical treatment. Acceptable method for removing pesticides on soil.

CONS: slow process than mechanical treatment, possible groundwater contamination, can't remove contaminants on deep soil.

Front 24

STORMWATER MANAGEMENT INFORMATION COMING FROM

Back 24

local ecologist, climate, site and local municipality.

Front 25

GRADING PLAN- WHEN POORLY DESIGNED

Back 25

higher cost

increase flood potential

increase sedimentation

higher volume of runoff

lower quality of storm water

Front 26

RAMPS

Back 26

ONE WAY- 3' MIN

TWO WAY - 5' MIN

5' MIN FOR ALL RAMPS

30' MAX FOR LANDING DISTANCE

MAX SLOPE 1:12 OR 8.33%

Front 27

INFILTRATION TRENCHES

Back 27

use when there is only a small amount of land or space shall be used for more than one thing.

Front 28

RETENTION BASINS

Back 28

store water for a period of time until either infiltrates the soil or evaporates

Front 29

DETENTION BASINS

Back 29

permanent flood with water

Front 33

DECKS- POST AND BEAMS

Back 33

ALL BEAMS SHALL BE AT LEAST THE SAME WITH OF THE POST OR WIDER TO PREVENT WATER FROM GATHERING AT THE TOP OF THE POST

Front 34

BEST MANAGEMENT PRACTICE- LIFE SPECTANCY

Back 34

CONSTRUCTED WETLAND- 20 Y

WET POND - 20 Y

GRASSED SWALE AND SAND FILTERS - 20Y

INFILTRATION TRENCH - IS LIKELY TO FAIL FIRST BY GEOTEXTILE CLOGGING

Front 35

WOOD DECKING CONSTRUCTION

Back 35

flashing shall be used when moisture builds up may be a problem. hot dipped galvanized fasteners decrease corrosion. The blunt tips of nails do not increase the possibility of corrosion. Bottom of post shall be at least 6" above grade.

Front 36

SOIL AND EROSION

Back 36

SILT SOILS ARE MUCH EASIER TO ERODE THAN OTHER SOILS

ORGANIC SOILS ARE VERY PERMEABLE AND THEREFORE DONT ERODE AS MUCH AS SILT SOILS
