Presentation Transcript


1. Surveying For landscape construction

2. The tools Level or transit Tripod Rod, decimal or inches and feet Steel tape Clip board Pins Marker paint

3. Surveying Level the level

4. Surveying Attach legs to scope assembly Extend legs Set legs in ground, roughly level Align scope over adjusting knobs Turn knobs until bubble is centered All feet must touch base plate Rotate scope 90 degrees of other knobs

5. Surveying Adjust knobs until bubble is centered Repeat as needed, until bubble stays centered If it doesn’t work, the bubble screws have been tampered with.

6. Surveying tampered screws If this has happened, set up the same way Align scope over one set of knobs Alternatively adjust screws half way and knobs half way Rotate scope 180 degrees and repeat until bubble stays centered

7. Surveying decimal rod View through scope Each b/w bar is 1/100 of a foot

8. Surveying inches and feet rod View through scope Each b/w bar is 1/8 inch

9. Surveying 90 degree angles Top view

10. Surveying 90 degree angles Top view

11. Surveying height Height of instrument 4.43’

12. Surveying height Height of step 3.54’ 4.43’-3.54’=.89 feet x 12=10.68 inches =10 5/8”

13. Surveying height with feet & inches rod Door sill reading =3’ 3 ½” + Decking 1 ½” + Joist 9 Ό” + Beam 9 Ό” + New reading At 4’ 11 ½”

14. Surveying height, decimal feet Height of instrument= 4.56’

15. Surveying height, decimal feet Rod reading .75’ 4.56’-.75’=3.81’ height of hill

16. Surveying height, feet & inches Height of instrument= 4’ 3-1/2”

17. Surveying height, decimal feet Rod reading 7 1/2” 4’3 ½”-7 ½”= height of hill Height of hill is 3’ 8”

18. Surveying height fore sight

19. Surveying height fs 1.23’ bs 6.75’

20. Surveying notes Tp Fs Bs Dif 1 1.23 6.75 5.52 2 2.21 5.42 3.21 3 3.42 4.41 .99 Totals 6.86 16.58 9.72 16.58-6.86=9.72 same Add Fs, add Bs, find difference= Total difference in elevation

21. Surveying notes Tp = turning point Fs= fore sight Bs= back sight You must set up transit at each tp Take reading, rotate 180 degrees Take new reading Add fs, add bs, find difference

22. Surveying notes To double check yourself Find difference between each fs & bs Add up all differences Compare with other method If they are not the same There is a math error

23. Topography Lay out a grid using baselines at 900 Mark base lines at 20’ intervals Mark intersecting points Take readings at each intersection

24. Topography Locating topo lines

25. Topography Locating topo lines

26. Topography Is X a hole or hill?

27. Topography It’s a hill. The #’s are elevations

28. topography The grids and elevations can change If the area is large as in square miles The elevations may be 50 or 100’ The grids may be in square miles In small areas the scale might be 1’ elevations and 10’ grids.

29. topography There are computer programs that will plot for you but you must still measure and enter values

30. Surveying A dumpy level or transit can be used to; Level construction projects Check plumb Square up projects Determine deck post cut off Check drain grade Many other uses
