Homeowner Terry Maitland cuts down a tree to make way for the new foundation, while the crew lays out the excavation lines using a small laser level. Excavation contractor Herb Brockert arrives to dig, while out back the old septic field is expanded with a new tank and new leach lines. Inside, the guys review the demolition plans, pointing out the importance of not going beyond the planned areas of reconstruction. Architect Chris Dallmus guides us through a model of the new addition and discusses a possible window choice. Halfway through the excavation, Herb hits large boulders or ledge at about four feet, dashing the Maitlands hopes for a full basement.
