Ten Surveying Instruments and Equipment Items

No.	Instrument / Equipment	Primary Function	Key Field Note
1	Automatic Level	Establish horizontal line of sight for leveling	Level instrument carefully and eliminate parallax
2	Electronic Theodolite	Measure horizontal and vertical angles	Center precisely over the station
3	Total Station	Measure angles, distances, and coordinates	Verify prism constant and orientation
4	Surveyor's Compass	Measure magnetic directions/bearings	Keep away from magnetic disturbances
5	Steel Tape	Direct linear measurement	Maintain alignment and appropriate support
6	Leveling Rod	Receive level/stadia readings	Hold vertical and keep graduations readable
7	Prism and Prism Pole	Reflect EDM signal to total station	Maintain correct prism height and verticality
8	Ranging Rod	Mark/range survey points and lines	Keep vertical and visible from the instrument
9	Plumb Bob	Transfer a point vertically	Protect from wind and verify centering
10	GNSS Receiver	Determine coordinates from satellite observations	Record coordinate reference and quality indicators

Twenty Surveying Hand Signals

The exact gesture used in class should match the instructor's demonstrated convention. The table records the intended communication represented in the finished RW.

No.	Signal / Command	Intended Meaning
1	Move left	Shift target/rod to the observer's left
2	Move right	Shift target/rod to the observer's right
3	Move forward	Advance away/toward assigned direction
4	Move backward	Return toward the previous position
5	Come in	Move closer to the instrument/line
6	Go out	Move farther from the instrument/line
7	Raise rod/prism	Increase target height
8	Lower rod/prism	Decrease target height
9	Hold position	Stop movement and remain fixed
10	Rod/prism vertical	Correct or confirm verticality
11	Mark point	Establish/mark the current point
12	Pick up point	Remove or recover the mark/target
13	Ready	Target person is prepared for observation
14	Observation complete	Reading has been accepted/recorded
15	Repeat observation	Reoccupy/hold for another reading
16	Move to next station	Transfer to the next assigned point
17	Tape tight / apply pull	Remove slack and establish measurement condition
18	Stop / unsafe	Suspend activity immediately
19	Traffic clear	Safe to continue the controlled measurement
20	Return to instrument	Report back to the instrument station/team

Discussion

Surveying instruments differ in precision, purpose, and reference system, but all require careful handling, traceable setup information, and consistent communication. Hand signals are especially useful when distance, traffic, noise, or site conditions make verbal communication unreliable.

Conclusion

The ten instruments/equipment items cover basic linear, angular, vertical, electronic, and satellite-based surveying. The twenty field signals support clear coordination between the instrument operator, target/rod personnel, tape personnel, recorder, and safety observer.

Submission: Handwritten RW due on the next class meeting. Any printed instrument or hand-signal illustrations should be labeled and attached cleanly to the handwritten work.
