The
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.
