Surveying. and Graphics 2015 Fall Term Assignment 06: Total Station 2 and AutoCAD 2: surveying our built environment Due the following week Introduction The total station is a sophisticated instrument that we use to measure distances and angles. It uses advanced measurement technologies complemented by an “on board” computer system able to record measurements and environmental parameters. as well as calculate basic trigo-­ nometric parameters that become a fundamental part of our Surveying activities. The purpose of this exercise is to familiarize students with the set-­up and operation of total stations in Survey-­ ing. This instrument will be use throughout the entire rest of the assignments. Download the TS06 Manual prepared for this tutorial (and class). alternatively. also download the Leica Total Station user manual and quick guide from CULearn. Equipment Take the Total Station kit and tripod. Beside the instrument, the kit should contain the following items: mini prism rod and reflector, two batteries, distance holder for height meter, instrument height meter protection cover, lens protection house. USB 1GB Leica, and USB cable. All team members are responsible for the proper operation. maintenance and integrity of the surveying equipment assigned. Equipment damaged by wanton negligence or improper use will be charged to the team. Teams must return the equipment to the structures lab. 2032 MC at the end of their tutorial. A manual is also provided. Location This will be an “outdoor” tutorial. The instructor has assigned a work area next to the Canal Building and McKenzie Building to conduct this exercise. Students must meet in the lobby of the Bell Theatre at their designated tutorial time to pick-­up the equipment and be directed to the surveying site locate din the Canal Building area. The data collected today will be used for your Final project. Each team will have its own scope of surveying (see Figure 2). Use Figure 1 to identify the benchmark where your group will be working. Part one Set-­up operations Tripod. The instructors will designate a point for your team to set-­up the tripod, center and level. over the designated target station (or fix point). Instrument. The instructor will demonstrate the leveling and proper installation of the TS over the tripod. Also he will demonstrate how to take the height of the instrument over the station. Part two Measure one point. A single point will be identified in the field to be measured from the current location of your TS. as follows: -­‐‑ Control again that your instrument is level as indicated by the CIVE2004 T06 Leica man-­ ual -­‐‑ Power the Total Station (press side red button and hold for 5 seconds);; Assignment 6 – Total Station 2 and AutoCAD 2 – Page 1 of 12 Department of Civil and Environmental Engineering. Carleton University -­‐‑ Follow instructions on the “TS06 leica Manual prepared for class and tutorials” -­‐‑ Record measurements on your notebook as they appear on the screen;; -­‐‑ Use recorded information to calculate the current position of your instrument (see part 6). Part three: Before starting to work, position the instrument on top of the desired fix point, and level it: 1. Please make sure that the following settings are correctly in place: 2. Switch on the instrument by pressing the side red power button for 5 seconds 3. When the “Service check recommended…” message appears, hit “cont (F4)” 4. Spread the legs of the tripod over the fix point 5. When the screen “Level & Plummet ½” appears. Id it does not appear press the “FNC” and level select “2”. 6. Use position of laser plummet (see button laser bin) to spread the legs over the desired fix point 7. Use the water level with the help of two legs to roughly level the instrument 8. When the electronic level appears, use the screws to find the correct leveling 9. Check that the instrument is still on top of the fix point, if not move the metal plate of the Total Station and re-­level. Part four: check settings 10. On the Main “Leica FlexField Plus” window: 11. Select “settings” by pressing 5 or using the arrows and hitting “enter” 12. On “Settings” go to “regional” by pressing 2 or using the arrows and pressing “enter” 13. Press “page” icon on the middle upper part of the keyboard to go to the next page 14. Now check: 15. On “angle unit” set to O ‘ “ (degrees, minutes, seconds) or “dec. deg” if you prefer 16. On “Dist. Unit” set to meter 17. Press “cont.” Part five Check Electronic Distance Measurement (EDM) Mode: 1. Back on the “Settings” menu go to “EDM” by pressing 5 or using the arrows and hitting “enter” 2. If using the Laser (No prism) go to EDM Mode and select the “NP-­Precision” 3. If using the kit mini prism go to EDM Mode and select the “P-­Precise & Fast” and on Prism Type select Mini (GMP) 4. You can also turn the laser pointer by going to “LaserPoint” and set to On, but by keeping this on your battery will run down quickly. 5. When done press “cont” 6. Now back on “settings” press “ESC” to go back to Leica FlexField Plus” window Part six: Setting up the Total Station knowing a station point and an orientation angle (azimuth): 1. Walk around the area and make a detailed sketch of the area you want to measure with all the features and enough space to put Point ID corresponding with the measurements you will be collecting. 2. Switch on the Total Station. Select Prog from the MAIN MENU 3. Position and level the instrument 4. On “Leica FlexField Plus” menu pick “Programs” using the arrows and hit “enter” 5.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
