This Old House - Season 26 Episode 6 Prefab Systems Speed Things Up - The Carlisle House

Tom uses laminated veneer lumber to make up 40-foot beams that will support the first floor deck of the barn. Kevin meets panelized construction specialist Jim LeRoy to watch the I-joist floor panels for the new ell swinging into place with a crane. Norm meets structural insulated panel expert Frank Baker to see the SIPs wall system go up. After discovering that several of our old trees are sick with the fatal diseases Dutch Elm and Ash Yellows, certified arborist Matt Foti brings in two crews with bucket trucks to safely remove them. At the end of the day, Tom and Norm are surprised to learn that the barn was built with one side shorter than the other - a quirt that will cost them time and money.
