This Old House

Tommy and Kevin take a road trip to see how the steel beams used in our house are fabricated.  The beams are trucked to the site and Kevin finds Tommy supervising erection on the back of the house.  The third floor has been demo’ed and now Richard can start an HVAC plan for the second floor.  He’s looking on the third floor for a location for an air handler and duct work to provide air to the floor below.  The front porch must be demo’ed to make way for a new design.  With the help of heavy machinery, Tommy’s crew does the job quickly. Then Tommy walks Kevin through the process of placing footings for the new porch.  Kevin finds Mark McCullough working on the firebox.  Kevin wants to learn the dark art of figuring firebox size and chimney height.
