restoration of buildings can be significantly aided by archaeological
study.  Some grant and loan programs insist on archaeology as a component of the restoration.  Direct benefits include the recovery of construction details such as wings, foundation locations, previous build episodes and construction details. Excavation might also recover original hardware and in some cases, paint chips.

            Also, since buildings are a part of a larger archaeological site, information about the people who lived or worked at a building is collected providing a broader context for the interpretation of the standing structure.

            These projects are typically driven by the specific needs of the restoration project rather than
archaeological research potential.  Usually, the first concern is foundation repair.  Archaeological features important to dating the building and which might offer useful reconstruction details that might be destroyed by foundation repair include builder’s trenches, porch piers or post holes, and drip lines.  Special consideration of the state of the building and the overall project goals are generally required.
