Transportation lock

17
Q

5 steps to set footing height from a benchmark

A

1) refer to benchmark height
2) initially read BM from level
3) read back sight
4) calculate difference
5) adjust footing height referencing result and builder requirements

18
Q

5 leveling errors

A

1) not adjusting split bubble on a tilting level
2) calculation mistakes
3) instrument out of adjustment
4) altered benchmark
5) target rod out of plumb

19
Q

What 7 factors influence the depth of an excavation?

A

1) frost depth
2) height of first floor above finished grade
3) basement window size requirements
4) footing depth
5) land contour
6) sewer line depth
7) surrounding buildings

20
Q

List out old and new school levels

A

Water level
Hand levels
Rotary laser
Automatic level
Manual (builders) level

21
Q

Describe the 4 main steps to using a transit for layout

A

1) set up transit over reference stake
2) aimed at reference on same building line
3) transfer building line down into excavation
4) repeat for minimum one line AT RIGHT ANGLE to original

22
Q

Can you use intersecting string lines and a long level to drop a reference point into an excavation?

A

Yes. As long as the level is PLUMB

23
Q

Can you use backfill for UNDERNEATH a building foundation?

A

No.

24
Q

What is the term when soil is disturbed and increases in volume?

A

Bulking

25
Q

Is the water table for eating off of? If not, what?

A

It defines the point at which the soil is fully saturated with water

26
Q

Do you have to worry about frost depth if a building is being constructed on top of rock?

A

No.

27
Q

List soils in best to worst load carrying

A

1) sand/gravel: doesn’t stick, doesn’t compact
