CM 2105 FINAL DELATTE newest actual 2025/2026 QUESTIONS
AND ANSWERS. Verified/graded a+.
Point used in Differential leveling process to temporarily
transfer elevation from the HI - ---Answers---Turning Point
End a level loop at a known benchmark - ---Answers---
Closed Loop
BM + BS = - ---Answers---HI
HI - FS = - ---Answers---TP elevation
Scope: Determination of elevations "profile" along the
centerline of a route
1) plotted profile allows user to "observe" general slope of
ground
2) determine where drainage structures should be located
3) calculate amounts of cut/fill from the existing profile to a
proposed profile - ---Answers---Profile Leveling
Scope: useful in the computation of volumes
1) determines elevations for line perpendicular to the
centerline
2) Planning
,3) elevation spots
4) Accuracy Requirement
5) Equipment
6) Hand level to GPS - ---Answers---Cross Section Leveling
Scope: excellent method for determining volumes of
irregularly shaped excavations
*typically a redundant activity (dying out) - ---Answers---Grid
Leveling
Most common method: use a calibrated chain and transfer
along a column vertically - ---Answers---Transferring
Elevations
Infinite number of ways to apply leveling
1) bucking in elevations
2) setting the instrument at the same elevation each day - ---
Answers---Applied Leveling
Can be existing objects
example: Brass Monuments in Concrete - ---Answers---
Setting Benchmarks
1) Minimizes the possibility of errors and blunders
2) 3 wires are read for one elevation reading (procedure)
, 3) Average of 3 wires is determined (note keeping) - ---
Answers---Three Wire Leveling
- setting elevations is most frequent use of leveling
- no mistakes (100% correct)
- Balance BS and FS
- Obtain HI from 2 benchmarks - ---Answers---Setting Grade
Visible Light
Electronic Level - ---Answers---Types of Lasers
1) Fixed
-pipeline
-pocket
-carpenters
2) Rotating
-horizontal plane
-vertical plane
3) Utility - ---Answers---Classes of Lasers
Line and Vertical Lasers
Pocket Lasers
Walls
Ceilings - ---Answers---Interior Lasers
