On Saturday April 26th my mentor, Jose Quintero, and I went an observed an actual PG&E construction site near San Ramon. Before arriving to the site we were required to wear a long sleeve shirt or sweater which was mandatory, everyone was also required to wear a hard hat for safety. Once arrival there was a meeting with the supervisors and all the construction workers. In the meeting gathering everyone was giving the safety procedures and guidelines, and also time for the workers to ask any questions they had concern with. Once the meeting had ended the workers took their respective areas and jobs and began to work. The channel where the pipe was going to be inserted was already dug up. My mentor and I observed the whole projected while he also made sure the final edits to the blue prints went through and will be used. The gas was shut off throughout the whole circuit of pipes in order to replace a section of the pipe. The workers used a monkey claw type of machinery tool to place the pipe in the ditch. While in the ditch it was welded on to each of the different pipes that were on each side of the newly placed pipe. Once the pipe was welded, a pig launcher was placed in the pipe used to see if the gas would be able to flow and see how much pressure it can withstand. We then went to get lunch and we discussed what we saw and why they take all the procedures they take. We then discussed the next steps they would be taking to finish replacing the section of the pipe.
