first visit

On march 21st we made our first visit to the job site at Stanford university. My mentor Tommy and I inspected the installation of the existing HVAC system. This picture shows the HVAC duct work above the chilled and heating hot water lines. The duct work with the chilled and heating water lines was demolished. After that process they were put into the dumpster for recycling. They will be recycled at the local garbage company, Allied Waste Services.

 

We then continued to tour the site. we observed the new HVAC system installation taking place. This picture indicates the installation of a plenum wall system. the two men are working on the roof. The walls are 80% complete.

job visit

My mentor and I met on Monday 3/17. We decided to  visit  the job site on Friday located at Stanford University on 267 campus drive . It is a research animal facility which requires retrofitting to bring it online with todays standards. We will walk the site on discuss the logistics of this remodel. It requires relocation of the research animals first. We will observe how the animals are moved to the temporary location. After that we will look at the HVAC systems that need to be demolished. This includes ductwork, chilled water, boilers cooling towers,etc.We will then check the logistics of the new installation of these systems. We will measure the equipment versus the buildings openings and crane access for fitment.

metting number 2

On Sunday March 2nd we made our way down to Critchfield Mechanical Inc., 1901 junction avenue San José 95131. We took a tour of the facilities. We went into the office first where the engineers designed the systems, the detailer's detailed the systems, the shop foreman watches over the shop and the sheet metal mechanic inputs the computer to send to the water jet plasma cutter. We then entered the shop where I was shown the piping and sheet metal departments. The piping department has large cranes to positions the pipe for loading and spherical welding. Then we walk through the shop to the warehouse where all the material delivery trucks are staged. These trucks are used for delivery for sheet metal, piping, tools and material need. After that we walked back to the sheet metal fabrication shop. We observed a press brake in action that bends metal to fabricate duct work. then we walked over to the shear machine which cuts metal for duct fabrication. After that we observed the plasma machine burning metal that had been downloaded from the sheet metal mechanic to fabricate duct work for HVAC systems.
