7/25/20138 hoursOn the first day, I was introduced to the other mechanical and electrical engineers that worked in the company, dHA and Calpec. Then I was given a packet that lists some of the basic terms and symbols for mechanical engineers. I was introduced to the drafting engineering computer program called auto-cad. Once I learned the basics in utilizing the tools on auto cad such as drawing lines and adding diffusers, I was given a mini project, which was to sketch the duct work for West Valley College (most building sketches are drawn on two programs: auto-cad and Rivet). The project was basically I was given a blue print of the duct work (tubes that help circulate the air conditioning) of West Valley College and I need to draw all of the duct work on auto-cad. As I was drawing on auto-cad, I also took pictures of my work.8 hours

7/26/20138 hoursOne of the mechanical engineers, Tony, taught me how to make text on auto cad. He also taught me about the scale of the blue prints. For instance, in real life a table the ceiling is 20 feet in width, but on the blueprint it’s only 5 feet, because the blue print is in ¼ scale. With this new information, I resized the ducts and added text on each of the details of the drawing. I drew more ducts in the chemistry lab section in the project. Then I attempted stainless steel on the ducts. As I was drawing on auto-cad, I also took pictures of my work.16 hours
4
8/1/20138 hoursStarted working on the green room portion of the project. Again drawing more ducts. I also learned how to draw circles (it was actually really difficult), which would symbolize as my fume hoods for my ducts. Once I was mostly done with the double line ducts, I started to connect the single line ducts to the diffusers. As I was drawing on auto-cad, I also took pictures of my work.24 hours
5
8/2/20134 hoursI finished the first room of the project and started the second room of the project. On the second room, I drew more ducts (I’m sorry if it’s repetitive, but this is what I really did). I learned how to use the hatch tool, which helped made putting on stainless steel on the ducts much easier. As I was drawing on auto-cad, I also took pictures of my work.28 hours
6
8/8/20138 hoursI started to add more ducts that were “curvy”. The first room dealt with less of these “curvy” ducts. I drew more fume hoods and added more stainless steel. I also tried to fix some of my diffusers because I believed I misplaced some of them. As I was drawing on auto-cad, I also took pictures of my work.36 hours
7
8/9/20138 hoursIn the morning, I went to get my hours signed by the President of the company. I learned how to add the hidden line type, which basically tells the architects and the other engineers that, symbolizes the ducts overlapping. I also learned that the architects draw everything out including some the interior structures of building. Tony told me that mechanical engineers have to correct the architects and move some of the mechanical parts that are misplaced. This helped me move more of the diffusers into the correct positions and change the position of the duct-exhausts. As I was drawing on auto-cad, I also took pictures of my work.44 hours

9/20/20132 hoursIt was my first day of my new mentorship, structural engineering. During my first day, my mentor taught me the foundations of roofing for a small homes. These foudnations included the different type of loads that affect the roofing and how to calculate loads. Then my mentor showed me three sketches of the different types of views of roofings and showed me the lengths and widths of each section of the roofing. 2 hours
12
9/25/20133 hoursI told my mentor the focus of my senior project and my EQ. Because my EQ dealt with the affects of earthquakes, my mentor taught me one of the key foundations to earthquake resistance, the SMRF (Special Movement Restraint Frame Elevation). He showed the details of one of the basic SMRF systems, which was usually based on two pad footings, two SMRF columns, a SMRF beam, a grade beam, and a grade slab. After he taught me the basic details of the SMRF system, he showed me mathmatically (through formulas) and artistically (through drawings) how the SMRF system gives enough time for people to evacuate a building during an eathquake. Then he made a rough sketch on the SMRF and told me to start drawing the SMRF on AutoCAD.5 hours
13
10/2/20135 hoursI continued to draw the SMRF on AutoCAD and it took lots of my time. I know, I am experienced with using AutoCAD; however, it took me a while to be a familiar with it, since I haven't used AutoCAD for more than a month. During the first hour working on AutoCAD, I had to do a little bit of trial and error and had to constantly ask my mentor if my drawing of SMRF was accurate. Eventually, I became more comfortable with AutoCAD and I began to work more productively. At the end of the day, I finished sketching the two pad footings and the grade beam of the SMRF.10 hours
14
10/3/20135 hoursAgain, I continued working on the SMRF drawing on AutoCAD. For most of the time, I worked on the columns and the beam of the SMRF. Most of the details in these structures dealt with indicating which parts were steel frame and aligning the measurements with the footings and the grade beam.15 hours
15
10/4/20137 hoursFinishing the last couple of details of SMRF on AutoCAD, I started all the parts of the SMRF system. Once I was done, my mentor told me to print my work, so he can see if my AutoCAD drawing is accurate to his drawing. I was hoping my AutoCAD drawing wouldn't have any errors because I didn't want to redraw or add anymore details. Unfortuantely, there were some errors, so I had to fix some of the errors in AutoCAD. After three checks from my mentor, I finally finished the SMRF drawing on AutoCAD.22 hours
16
11/5/20135 hoursToday, I was taught about more of the specifics of the SMRF. My mentor showed me an actual blueprint of the SMRF and focused on the panel zone of the SMRF. The panel zone is the area of intersection between the SMRF column and the SMRF beam. The blueprint of the panel zone gave a blowup view of the panel zone. In the blueprint it showed me new details that indicated welding. My mentor taught me how the steel structures in the columns and the beams are cut at a certain angle in order for welding to take place. After my mini lecture was over, my mentor gave me a new assignment, which was to draw the panel zone on AutoCAD. 27 hours
17
12/25/20135 hoursMy mentor wanted to focus on several parts of SMRF. He sketched a blowup version of 3 parts of the SMRF. With the sketches, he wants me to again compute his sketches to AutoCAD. Most of the details involved labeling, adding bolts to specific structures, and indicating flanges.32 hours

12/27/20137 hoursI continued to work on the 3 parts of the SMRF. During myAutoCAD work, I came across a problem in the welding section during my sketch with the footings. I had to indicate which areas required welding on the column connecting to the footing. The problem with this was indicating welding was troublesome because I had to draw the welding in a certain way. I eventually understood how to draw the welding features, but it took lots of my time to perfect this, because the welding areas are so small in the drawing.39 hours
23
1/20/20145 hoursI did more drawings on AutoCAD and worked on part D on the SMRF. Part D included the grade slab, on top of the footings of the SMRF. My drawing was focused more on the details within the grade slab. This details in the grade slabe were mainly soil, rebars, and bolts.44 hours
24
2/3/20145 hoursI continued workin on part D of the SMRF and finished all the details. Then I went back to my old drawing for part C of the SMRF, the panel zone. I didn't quite finish all the details for the panel zone. Most of the details were finished, but I didn't finish labeling all the details. So I at the end of the day I finished part D and Part C of the SMRF.49 hours
25
2/18/20144 hoursI needed to focus on my two other answer, so I asked my mentor on explaining what time history analysis, since I didn't fully understand when I was doing my research checks. He gave me a better explanation and showed me some sites in where I understand it better. Basically this time in my mentroship, I was studing more on time history analysis and how it really impacted a building's design. 54 hours
26
2/19/20143 hoursLike yesterday, I decided to focus on my other answers, and I stumbled across ground motion maps. I also didn't fully understand ground motion maps, so I asked my mentor to explain how are these maps helpful. After thourgh explanation, I just decided to research more on ground motion maps, because my mentor did not have time to give me a task due to his own job meetings.57 hours
27
2/23/20147 hoursI needed more mentorship hours so I decided to download AutoCAD onto my desktop at home and worked on designs given from my mentor at home. Recently I've been given the MF Column / Pad Footing from my mentor. It was similar to some of the other drawings I accomplished earlier in the year because of it was a footing design. However, I it was important for me to continue to work on footing designs because footings are foundational structures, which help me give a better understanding of how foundations help sustain load. 64 hours
28
3/5/20147 hoursMy mentor gave me another assignment regard connections between beams and columns. This design was called Beam column connection, (I'm not joking). WHat was different in this connection design prior to one of my other ones is the beam and columns are longer and they overlap. But likewise, the purpose of this design is like it's title to connect with other buildings. These connections are vital in not just for earthquakes but stability. In fact, the reason the northridge earthquake did do some damage was because of connection failure, but also because of these connection failures, potential damage was lessened. 71 hours

(used for independent component 2, the 30 hours of this part of Mentorship log)
31
3/15/20147 hoursI continued working on the column footing structure on AutoCAD. I finished designing the dowels and the base plate. This is located within the grade beam of the column footing design. I also cointinued working on the Beam Connection design finishing the end plate typ.78 hours
32
3/19/20147 hoursI finished detail B of the Beam Column Connection design by labeling all the parts. I continued to work detail C of the Beam Column Connection Design, which was mostly designing the same parts as detail B, except the vertical column is much shorter and cuts off at the CAP plate.85 hours
33
3/24/20145 hoursI did more research on the building code ASCE 7 since it was part of my third answer. The AutoCAD designs help me gain more knowledge on the foundation and my answer 1 on my EQ, so I felt like I needed to try to focus on my other answers. My mentor showed me his blueprints and how the requirements of ASCE 7 are used. 90 hours
34
4/7/20145 hoursAgain I researched more on the building code ASCE 7 and asked one of my interviewee's to help give me more insight on the requirements. Basically, all engineers follow all the requirements of ASCE 7 and without these requirements, there is no set standard for a building design not just for seismic resistance.95 hours
35
4/12/20142 hoursI asked the same interviewee during my last mentorship visit on how does equivalent static analysis work. He gave me an article from HLA texas engineers and it showed a clearer explanation on how similar to time history analysis that it is also uses a software to prepare a building for an earthquake.97 hours
36
4/18/20145 hoursMy mentor taught me how the "schedule" on the drawings. Similar to the book my mentor showed me with the values of steel structures, the scheldue also has a set of values that used to identify the label/ structures on the drawings.102 hours
37
4/19/20147 hoursI finished detail C of the Beam Column Connection design by finsihing up the labels. I continued to work on the Column Footing Design and finsihed on designing the slabe underneath the grade beam and finished inputing all the bolts within the grade beama nd the slab. I also did some labeling on the area of the slab.109 hours
38
4/21/20147 hoursI finished the Column Footing Design by finishing all the labeling, and the top portion area which included the column and the slab. I also had to fix the design again because I forgot to input non-shrink grout and some of the dowels within the grade beam. I then got a new assignment from my mentor called Interior Pipe/HSS CoL. Pad Footing. It's three drawings of how the column base is connected with pipes.116 hours
39
5/3/20147 hoursThe drawings of Interior Pipe/HSS CoL. Pad Footing were easier because it was in a downward perspective (basically if a person looked down on a column). Most of the shape were squares or washer meaning there was hole within part of the shapes. This design also included schedule called the HSS CoL Base Plate Schedule. Most of the hard work was the labeling since most of it were notes. The labeling I did for the other designs didn't contain many "notes." 123 hours
