House raising
House raising (house lifting, house jacking, barn jacking, building jacking) is the process of separating a building from its foundation and temporarily raising it with hydraulic screw jacks. The process is the first step in structure relocation in which the building is moved to a different location. House raising may also be a part of a renovation to build a foundation under an existing house or make a house larger by building a new floor level creating a two story house. Often employed in areas that are prone to flooding and storm damage, this process can be achieved through the use of either timber piles or helical piles. Once a house is raised and supported on cribbing, a new foundation can be constructed beneath it. After Hurricane Katrina and Hurricane Sandy large numbers of houses in parts of Louisiana, New York and New Jersey were raised to avoid future flooding.
Cornerstone
In the Eastern Orthodox Church the blessing of the bishop must be obtained before construction on a new church may commence, and any clergyman who ventures to do so without a blessing can be deposed. The "Rite of the Foundation of a Church" (i.e., the laying of the cornerstone) will differ slightly depending on whether the church is to be constructed of wood or of stone. Even when a church is built of wood, the cornerstone must in fact be made of stone.
