Team: Wed 200L Green Squad November 1, 2023 MEP Daily Report # 8 Work Schedule Started: 9:00 am Clean up: 11:15 Finished: 11:30 General Description of Work ● The Green Team showed up with all proper PPE. ● Professor Womack and Professor Iacona briefed the teams on the tasks and hazards for that day which was installing MEP ● After Professor Womack was done starting the class, the foreman Latham Fritz went over the JHA to the Green team. This discussed the hazards for the day and the best ways to mitigate the risk ● Once all parts of the JHA were gone over, the green team placed the pallet in the correct location. ● We started by making a plan with our superintendent Maggie Helmen on who would work on what to start. Darren Lemell, Latham Fritz, and Luke Fulk were tasked to install the exhaust fan. Andrew Gera was tasked to work with superintendent Maggie Helmen to pull wire into our J-boxes ● After 15 minute of working, Professor Womack did a demo on how to solder. We all stopped work and went over to the middle of the C4P lab to watch Professor Womack’s demo (Figure 1). ● Luke Fulk attached the fan box assembly to the stud with screws. He did this according to drawings on Sheet ME1. ● Latham Fritz then test fitted the louver cover from the inside to make sure it would not hit any studs on it was installed from the outside (Figure 2). He did this according to the drawings on Sheet ME1. ● After test fitting from the inside, Luke Fulk cut the hole in the Tyvek and densglass. ● After the hole was cut, our superintendent Maggie Helmen inspected the hole. ● Luke Fulk then installed the cover with screws in all four corners (Figure 3).

● Darren Lemell attached the duct piping to the louver cover (Figure 4). ● Andrew Gera installed the j-boxes for the light switch per Sheet ME1. ● Andrew Gera pulled the MC wire into the j-boxes and connected the wires to the switches in the appropriate configuration (Figure 5). ● After that, we cleaned up our workspace and put the pallet back in its storage location. ● We then talked as a team with our superintendent to form a schedule for the next week’s work. ● Finally, our architect Noah Robinson inspected our work for the day. He said everything looked good and to spec. Safety ● JHA was discussed by the foreman Latham Fritz who talked about the hazards of electrical installation and how to solder. ● Some of the hazards involved in today's work were cuts, scrapes, use of power tools, shocks, burns, skin irritation, and use of A frame ladder. ● We talked about all the things we could do to mitigate as much of the risk as we can. This included the use of covers on power tools, being mindful of your surroundings, using caution when dealing with sharp steel, making sure to have 3 points of contact when using the ladder, wearing gloves, and having a clean and focused construction site. ● We also discussed what PPE we were using for that day. Green team made sure to wear gloves, hardhat, safety glasses, high visibility vests, and proper footwear at all times on site. Important conversations ● One of the important conversations we had today was with our superintendent, architect, and Professor Womack. We discussed and decided the appropriate way to run the conduit. This explanation made the installation very easy and smooth. ● Another important conversation we had was with Professor Womack and our superintendent. We were a little confused how to install the switches and connect the wires. Professor Womack explained it to us. Our superintendent took notes on Professors Womack’s explanation and reminded us throughout the remainder of the day on the correct way to connect the wires and install the switches.

Issues and Concerns  The issue today was communication. The day started off smooth but about 30 minutes into the build day, we got scrambled and people stated standing around doing nothing. To fix this, we took a 10-minute break and delegated tasks to each team member. This break and small meeting put us back on track for the day and kept everyone busy.  The second issue/concern was about how to cut the whole for the louver cover. Originally we had planned to cut the hole from the inside. We soon realized that the Tyvek on the outside would get stretched and distorted from the dry wall saw if we cut from the inside. To combat this, we transferred our cut mark to the outside. We first cut the Tyvek with a razor knife, then used the drywall saw to cut the densglass. This fix ended with the Tyvek being smooth and the whole being a clean cut.
